This broke when I was refactoring things earlier, because we no longer
have a direct reference to the contents array, instead using a copied
int. But we have a settile() function anyway, so why not use it?
It is impossible to get on the quicksave screen in time trials, because
Enter is always bound to restarting time trials in a time trial, and
there's no way to open the map screen otherwise.
So, I've decided to add a fun little message in case someone somehow
manages to get to this screen in a time trial.
As is typical, the code was copy-pasted to account for Flip Mode, and
then copy-pasted again to account for custom levels, leading to four
instances of the same code.
I clean this up while also improving code style. This is where the new
FLIP macro and the fixed PrintWrap help a lot - otherwise the "Game
saved ok!" screen would look really wrong without the height
corrections.
It now looks more like the FLIP macro in Render.cpp: The y-position is
simply the height of the area the object is being flipped in, minus the
y-position itself, minus the height of the object. So:
flipped_yp = constant - yp - height
This is just a mathematical simplification of the existing statement,
which is:
flipped_yp = yp + 2 * (constant/2 - yp) - height
Using algebra, the 2 distributes into the parentheses, so
flipped_yp = yp + constant - 2 * yp - height
And the two `yp`s add together, so
flipped_yp = constant - yp - height
It's more readable this way.
Also I am using a named constant instead of a hardcoded one.
Otherwise, the text will be in the wrong position compared to normal
mode.
PrintWrap is not used in Flip Mode yet, but it will be used on the map
screen in an upcoming change of mine. The FLIP macro in Render.cpp can't
help us there, since it would need to know the height of the wrapped
text at compile time, when the height is only figured out at runtime
based off of the string (or, well, right _now_ the string _is_ known,
but we are going to merge localization for 2.4, and it's better to
future-proof...), and only PrintWrap itself can figure out the height of
the text. (Or, well, I suppose you could call it from outside the
function, but that's not very separation-of-concernsy style.)
Flipping objects in Flip Mode needs to account for the heights of those
objects (that's why flipme text boxes in Flip Mode in 2.2 were
positioned wrongly).
Also, turn it into a macro instead of an inline function.
This changes the positions of all existing de-duplicated map menu text
in Flip Mode, but it'll be more correct.
I misread SDL's code and thought that SDL's `begin_code.h` was internal
only to SDL. It turns out you get it when you include basically any
header, such as `SDL_stdinc.h`. So use it directly instead of copying it
for our own.
Between accounting for Flip Mode and custom levels, this code was
copy-pasted three times, leading to _four_ instances of one code!
Anyways, I've cleaned it up. The position of the text in Flip Mode is
going to differ by 4 pixels from how it was previously, but that really
shouldn't matter.
While dying in No Death Mode was fixed to no longer say "One trinkets"
in 2.3, if you win in No Death Mode with one trinket, the game would say
"One trinkets".
So to fix this, just slot a ternary in there. The code is already kind
of bad anyways and is going to be refactored/de-STLed in the future
regardless, so I'm not feeling too badly about shoving a ternary in
there like that.
This macro is to make it so it won't be error-prone to write the
semi-confusing `(a % b + b) % b` statement, and you can just use an easy
macro instead.
Currently, the only places a positive modulo is needed is when switching
tilesets, enemies, and warp directions in the editor, as well as when
getting a tile in the tower, since towers just repeat themselves
vertically. Towers used this weird while-loop to sort of emulate a
modulo, which isn't half-bad, but is unnecessary, and I don't think any
compiler would recognize it as a modulo. (And if it's not optimized to a
proper modulo... what happens if the number being moduloed is really,
really big?)
Believe it or not, there are still some remnants of the ActionScript
coding standards in the codebase! And one of them sometimes pops up
whenever an integer division happens.
As it so happens, it seems like division in ActionScript automatically
produces a decimal number. So to prevent that, the game sometimes
subtracts off the remainder of the number to be divided before
performing the division on it.
Thus, we get statements that look like
(a - (a % b)) / b
And probably more parentheses surrounding it too, since it would be
copy-pasted into yet another larger expression, because of course it
would.
`(a % b)` here is subtracting the remainder of `a` divided by `b`, using
the modulo operator, before it gets divided by `b`. Thus, the number
will always be divisible by `b`, so dividing it will mathematically not
produce a decimal number.
Needless to say, this is unnecessary, and very unreadable. In fact, when
I saw these for the first time, I thought they were overcomplicated
_modulos_, _not_ integer division! In C and C++, dividing an integer by
an integer will always result in an integer, so there's no need to do
all this runaround just to divide two integers.
To find all of these, I used the command
rg --pcre2 '(.+?).+?-.+?(?=\1).+?%.+?([\d]+?).+?\/.+?(?=\2)'
which basically matches expressions of the form 'a - a % b / b', where
'a' and 'b' are identical and there could be any characters in the
spaces.
There's really no need to put the y-multiplication in a lookup table.
The compiler will optimize the multiplication better than putting it in
a lookup table will.
To improve readability and to hardcode things less, the new
SCREEN_WIDTH_TILES and SCREEN_HEIGHT_TILES constant names are used, as
well as adding a new TILE_IDX macro to calculate the index of a tile in
a concatenated-rows (row-major in formal parlance) array. Also, tile
numbers are stored in a temporary variable to improve readability as
well (no more copy-pasting `contents[i + vmult[j]]` over and over
again).
There's really no reason for this simple multiplication plus division to
be in a lookup table. The compiler will optimize it faster than putting
it in a lookup table will, I'm sure.
This comment was referring to a now-deleted variable named mkdirResult
that was binary-"or"ed with all mkdir() results... except for the saves
directory. That variable was only used for save file migration, which is
now axed, so this comment is referring to nothing now.
I don't really know the answer to Ethan's question, but it doesn't
matter now.
So, it turns out freeing everything in binaryBlob::clear() without
checking for NULL results in an abort() because clear() gets called on
musicWriteBlob after it attempts to write the compiled music. It's just
that no one's using VVV_COMPILEMUSIC, so no one's ran into this.
I'm keeping VVV_COMPILEMUSIC around so in the future people can compile
music directly from the game (and probably half the existing
VVV_COMPILEMUSIC code is going to be thrown out, but oh well).
Since this refers to specific exported file data, let's make sure this
is portable. I'm not sure if we'll ever ship on systems where
sizeof(int) != 4 or sizeof(bool) != 1, but better to be safer and
future-proof than not.
This variable is only used when compiling music. Since it doesn't
actually keep track of the number of headers otherwise, ifdef it behind
VVV_COMPILEMUSIC.
2.3 introduced a regression with destroy(platforms). The problem was
that isplatform wasn't being set to false when the entity got disabled,
so if the platform was moving, it would keep moving until it hit a wall,
instead of stopping immediately.
Previously, loading STDIN used std::istreambuf_iterator and std::vector
and whatnot because... I guess it was less typing? But this isn't 1989;
we have the disk space to spare and we don't need to use fancy stuff
just to save on typing. It's not that hard to implement an array that
regrows to the nearest power of two every time.
All system header includes should come before project-specific includes
(includes specific to this game), while coming after the include
specific to the given file (if any; main.cpp doesn't have any).
These are unused.
Ethan originally added them in case Terry wanted achievement
percentages. But he didn't add them, and I don't think the achievements
are changing anytime soon, so it's safe to remove this dead code.
If the string is hardcoded, then use compile-time string literal
concatenation instead.
I don't know if compilers are smart enough to recognize when you're
passing in hardcoded strings and to concatenate them into the string
literal at compile time instead. I also don't know that if compilers are
smart enough to recognize that, that further they recognize all the
logging functions are just wrappers around printf, and so they can
perform the same optimization at those function call sites, too. So it's
better to just do the string concatenation explicitly instead.
Instead of having three separate copies of the function list, use macro
magic to make it so there is only one list that we use in three
different cases.
SDL just got an API to toggle VSync without having to tear down the
renderer ( libsdl-org/SDL#4157 ). We can remove the workaround and use
that instead. For now, we are putting it behind an ifdef until SDL
2.0.18 officially releases in November.
Fixes#831.
Constants.h will house constants like the screen size and others. But
basically only the screen size for now.
Now we don't have to type that "4 bytes per 40 chars (whole screen)"
comment everywhere...
Since those are all downstream recipients of either static storage or
memory that doesn't move for the duration of the custom level, it's okay
to make these be `const char*`s without having to redo any of the RAII
memory management.
mapclass::currentarea() is included in this as well. I also cleaned up
Tower.cpp's headers to fix some transitive includes because I was
removing UtilityClass.h includes from all other level files too.
The "Untitled room" names no longer show any coordinates, because doing
so would require complicated memory management that's completely
unneeded. No one will ever see them, and if they do they already know
they have a problem anyway. The only time they might be able to see them
is if they corrupted the areamap, but this was only possible in 2.2 and
previous by dying outside the room deaths array in Outside Dimension
VVVVVV, which has since been patched out. Besides, sometimes the
"Untitled room" gets overwritten by something else anyway (especially in
Finalclass.cpp), so it really, really doesn't matter.
There's no reason it needs to be an std::string here.
Although, realistically, we should be using an enum instead of
string-typing, but, eh, that can be fixed later.
Companions would not spawn if you didn't load the current room via a
room transition. This meant that companions wouldn't spawn if you loaded
a save file with a companion, at least not until you moved to a
different room and triggered a screen transition. But most importantly,
it meant that the Intermission 1 supercrewmate would never spawn,
because going to Intermission 1 does a straight gotoroom, and does not
do a room transition.
Turns out the roomchange refactor broke things, because of course it
did. The companion logic was implicitly relying on that bool to be set,
because...? Either way, it doesn't make sense. Using roomchange implied
that the code wanted to be ran only when doing a room transition, which
is clearly not the case here. The best thing to do here is to just move
it to a separate function that gets called at the end of
mapclass::gotoroom().
So, I ended up breaking supercrewmate spawning with that roomchange
refactor. However, upon investigating how to fix it, I was running into
a weird interpolation issue due to scmmoveme, as well as the companion
spawning in the ground in "Very Good". And I was wondering why I or no
one else ended up running into them.
Well, as it turns out, scmmoveme ends up doing absolutely nothing. There
are only two instances where scmmoveme is used. The first is if you
respawn in "Very Good", and somehow have your scmprogress set to that
room. But that's impossible, because whenever you respawn, your
scmprogress is always set to the one after the room you respawn in. Even
if you respawned in the room previous to "Very Good" (which is "Don't
Get Ahead of Yourself!"), it still wouldn't work, since the logic always
kicks in when a gotoroom happens, and not only when a supercrewmate is
actually spawned. Since the scmprogress doesn't match, that case never
gets triggered, and we get to the second time scmmoveme is used, which
is in the catch-all case that always executes.
This second instance... also does nothing, because since we just
respawned, and our scmprogress got set to the room ahead of us, there is
no supercrewmate on screen. Then getscm() returns 0, and the player is
always indice 0, so the only thing we end up doing is setting the
player's x-position to their own x-position. Brilliant.
Anyway, this code results in interpolation issues and the supercrewmate
spawning in the ground on "Very Good" if you die, when my fix is
applied, because my fix moves this logic around to a different frame
order, and that actually ends up making scmmoveme no longer dead code.
So to recap: we have dead code, which looks like it does something, but
doesn't. But if you move it around in a certain way, it ends up having
harmful effects. One of the joys of working on this game...
It's also hilarious that it gets saved to the save file. Why? The only
time this variable is true, it is for literally less than a frame,
because it always gets set to false, because you always respawn using a
gotoroom whenever the supercrewmate dies, because you never respawn in
the same room as a supercrewmate, because Intermission 1 was
deliberately designed that way (else you'd keep continually dying since
the supercrewmate wouldn't move out of the way).
These were bfont_rect, bg_rect, foot_rect, and images_rect.
bg_rect was only used once to draw the ghost buffer in the editor, but
that was only because Ally didn't know you could just pass NULL in, cuz
the ghost buffer is the same size as the backbuffer.
RGBflip() does the exact same thing as getRGB(), now that all the
surface masks have been fixed. This axes RGBflip() and changes all
callers to use getRGB() instead. It is more readable that way.
By doing this, there is less copy-pasting. Additionally, it is now
easier to search for RGBf() - which is an ENTIRELY different function
than RGBflip() - now that the name of RGBf is no longer the first four
characters of some different, unrelated function. Previously I would've
had to do `rg 'RGBf[^\w]'` which was stupid and awful and I hated it.
Turns out, the r, g, and b arguments don't actually do anything!
There was a call to RGBf() in the function. RGBf() is just getRGB() but
first adds 128 and then divides by 3 to each of the color channels
beforehand. Unfortunately, RGBf() does not have any side effects, and
the function threw away the return value. Bravo.
This also reveals that the website images drawn in the credits in the
main menu are only recolored because of a stale `ct` set by the previous
graphics.bigprint(), and not because any color values were passed in to
drawimagecol()... What fun surprises the game has in store for me every
day.
This fixes a regression where entering playtesting while a track was
fading out (by exiting out of playtesting with a track playing and then
immediately entering back in with the level start music set) would
result in no music.
The cause is the game doing fades even though nothing is playing, which
puts it in a confusing state.
This wrapper function is for (a) future-proofing (b) proactive
prevention of future copy-pasting (c) to clarify that we never actually
halt music in the SDL_mixer sense, we only pause it, so to check if the
music is halted we actually check if the music is paused instead. This
is important because Mix_PlayingMusic() does not check if the music is
paused and Mix_PausedMusic() does not check if the music is halted.
When you're on the music changing screen in the editor, it plays the
current track. When you return, it stops playing the track. However, if
you press escape, it doesn't stop playing the track. This is because
pressing escape just returns to the previous menu without stopping
playing the track.
To fix this, I just added some kludge in the return menu function. This
is kinda super bad but it works for now and is just something to clean
up later. Maybe like each menu having exit callbacks or something, I
dunno.
This is kinda a regression, kinda sorta not. In 2.2 and previous,
pressing escape would just close the settings menu entirely, which also
bypassed the music fadeout. 2.3 made it so pressing escape doesn't
entirely close the settings menu, and just returns to the previous menu,
which fails in a different way. But the intended way is definitely to
select the return option and having the music fade out.
This function now properly deletes the Super Gravitron record, the Super
Gravitron rank, and the best game deaths. They were not being properly
reset previously, meaning you would have to go into your save file to
properly clean out your save data.
If the map size was less than 20x20, platv values outside the map would
end up being saved as 67372036.
This happens because SDL_memset() operates on the byte level, and not
the multi-byte level. So it takes only the lower 8 bits of 4 and repeats
it for each byte in each integer, creating 67372036.
This was done in 2.2 and previous probably to fix the fact that there
were multiple conflicting audio controls (the player wants to mute the
audio but the game wants to fade in the audio), but is now actively
harmful since 2.3, because muting the game while finishing the
completion prompt means the music will never come back in, even after
unmuting.
I also notice that when collecting a custom crewmate, the game checks
for the level's start music instead of if there's actually a current
song playing right now. I don't know why this was done, because it
would've been better to copy-paste the trinket collection logic here.
It's entirely possible for the audio to just be muted and never come
back if the level has no start music but plays a song by using a script.
Anyways, leaving it alone because it's quite possible that a level might
be intentionally designed around this, I can't really tell the
intentions of every level creator, and it's easy to work around (either
don't use custom crewmates, which every modern level basically does
nowadays, or just set the start music).
For some reason, when completing a custom level and fading to the menu,
the game attempts to fade the music in and also fade the music out at
the same time. This results in nothing happening at all, and in 2.2 and
previous, results in audio fading out from max volume while the game is
frozen on a black screen after the fadeout.
To avoid any potential badness, just remove these.
In the main game, if you press R during the trinket collection prompt
after collecting a trinket, AND you have never entered Comms Relay, and
you respawn in a different room, the trinket collection gamestate will
be interrupted, but you will still be left with the advance text prompt,
cutscene bars, and muted music.
The previous workaround to fix the music would be to mute and then
unmute the game, but due to the new music changes, this workaround
(which in and of itself is a bug) no longer works. Instead, the music
would have to be restarted by going into another zone on the map.
Having an advance text prompt outside of a cutscene results in the
player being unable to flip, but they can still move around left and
right.
Speedrunners previously used the no-Comms-Relay interrupting behavior to
skip certain trinket collection prompts entirely with a frame-perfect R
press, so I can't patch that out. Having an advance text prompt outside
of a cutscene is (ab)used in custom levels to intentionally prevent the
player from flipping, and furthermore, it's also used in credits warp
runs of the main game to increment the gamestate; so I cannot patch that
out. The ability to press R everywhere even during cutscenes was added
for good reason - to make it less likely that a softlock can happen - so
I don't want to revert it.
But I still think this is worth fixing because previously, the
punishment for missing the frame-perfect window late was simply not
skipping the trinket prompt (since the R-press would be ignored), but
now the punishment is basically having to reset because of the advance
text prompt.
I would usually handle this in gamestate 0, but awful custom levels
might want to intentionally interrupt the gamestate to do, I don't know,
something. No level does that so far, but I'd like to do the least
invasive thing.
So what I've done is made it so the effects of interruption are undone
if you press R and the gamestate is interrupted. This is handled in
mapclass::resetplayer().
Without this, `fixedloop` will loop infinitely until focus is regained.
However, Emscripten won't actually know that focus is regained until
`fixedloop` returns.
getBGR, when used in FillRect, was actually passing colors in RGB order.
But now the masks are fixed, so remove it, and fix up all existing
getBGR colors to use getRGB instead.
Due to the mask inconsistencies, getRGB calls that were passed to
FillRect ended up actually being passed in BGR order. But now that the
masks are fixed, all these BGR colors look wrong. So, fix up all of them
(...that's a _lot_ of copy-pasted code...) to be passed in RGB order.
This fixes the color ordering of every SDL_Surface in the game.
Basically, images need to be loaded in ABGR format (except if they don't
have alpha, then you use RGB? I'm not sure what's going on here), and
then they will be converted to RGB/RGBA afterwards.
Due to the surfaces actually being BGR/BGRA, the game used to use
getRGBA/getRGB to swap the colors back around to BGRA/BGR, but I've
fixed those too.
If it's at all possible to use `const std::string&` when passing
`std::string`s around, then we use it. This is to limit the amount of
memory usage as a result of the frequent use of `std::string`s, so the
game no longer unnecessarily copies strings when it doesn't need to.
I've made a new function, Graphics::do_print(), that does the actual
text printing itself. All the interfaces of the other functions have
been left alone, but now just call do_print() instead.
I also removed PrintOffAlpha() and just calculated the center x-position
in bprintalpha() itself (like bigbprint() does) to make it easier to
de-duplicate code.
Text boxes have `r`, `g`, and `b`, and `tr`, `tg`, and `tb`. `tr`, `tg`,
and `tb` are the real colors of the text box, and `r`, `g`, and `b` are
merely the colors of the text box as the text box's alpha value is
applied to them.
Compare this with, say, activity zones (which are drawn like text boxes
but aren't text boxes): There is `activity_r`, `activity_g`, and
`activity_b`, and when they're drawn they're all multiplied by
`act_alpha`.
So just do the same thing here. Ditch the `tr`, `tg`, and `tb`
variables, and make `r`, `g`, and `b` the new `tr`, `tg`, and `tb`
variables. That way, there's simply less state to have to update
separately. So we can get rid of `textboxclass::setcol()` as well.
This is a variable that's only used in one method, and it's always
initialized beforehand. No need to carry it around, taking up memory,
and making code analysis more complicated.
All parameters are now made const, to aid in the reader in knowing that
they aren't ever changed.
Useless comments have been removed and been replaced with helpful
comments.
Useless parentheses have been removed.
Spacing has been made consistent.
Declarations and code are no longer mixed.
I'm honestly not too sure why drawcustompixeltextbox ever existed? All
it seemed to do was draw even more horizontal/vertical tiles to finish
any gaps in the tiling... which was all completely unnecessary and
wasteful, because even the previous drawpixeltextbox implementation
covered all gaps in all custom level map sizes that I tried.
Anyway, that at least gets rid of one copy-pasted function.
This draws the remaining horizontal/vertical tile just beside the final
corner if the width/height is not a multiple of 8. (It'd be wasteful to
draw it if the width/height was a perfect multiple of 8, and result in
double-drawing translucent pixels if there were any.)
This has an advantage over the previous system of shifting the
horizontal/vertical tiling, in that custom corner textures don't look
weird due to overlapping like this. Now, custom horizontal/vertical
tiles _can_ look weird if they don't completely tile correctly (or if
they have translucent pixels), but that's better than mucking up the
corners.
`w` and `h` are provided alongside `w2` and `h2`. `w2` and `h2` are in
blocks of 8, while `w` and `h` are in pixels. Therefore, `w2` and `h2`
can just be figured out by diving `w` and `h` by 8.
Also, `xo` and `yo` were used to slide the horizontal/vertical tiling of
the text box a bit into one set of corners, so the horizontal/vertical
tiling wouldn't visibly overlap with the other corners, if using default
textures. This requires hardcoding it for each width/height of text box,
which isn't something that's generalizable. Also, it results in corners
that look weird if the corners have custom textures that don't adhere to
the same shape as default textures.
In the next commit I'll fix the non-multiple-of-8 text box dimensions
differently. Can't do it in this commit or the diff looks weird (at
least with my diff algorithm).
This fixes a bug where the player could bring up the map on the very
first frame of a gamemode(game) animation. This is because the menu
animation checked graphics.menuoffset, but graphics.menuoffset wouldn't
have changed at that point because it only set graphics.resumegamemode.
Instead, just check for graphics.resumegamemode directly. We also need
to assign it to false whenever the map is closed so the player won't be
prevented from using the map screen again.
This fixes all the headaches about map.extrarow having to be the correct
value and which way it should be and whatnot. The latest headache was
the detection that prevent user-initiated menu animations while an
animation was already happening being tripped because
graphics.menuoffset would be 230 (due to closing the menu while being in
a room without a room name), but then going to a room with a room name
would check for 240 instead, and 230 is less than 240. (The numbers are
the wrong way round because I got the ternaries the wrong way round, but
even if the numbers are the correct way round, the bug would still
happen, but it would just be reversed.)
So instead, I've just made it 240 for both. This doesn't change the
duration of the menu animation (because the animation moves in
increments of 25, and 230 / 25 == 240 / 25 under integer division). It
might change the animation slightly, but it was already inconsistent
anyway because map.extrarow was always set to be 1 in custom levels, and
I legitimately would not be able to tell the difference without
recording the animations and nitpicking it frame-by-frame.
Fixes#841.
The player gets kicked out of the Super Gravitron if they have
invincibility or slowdown enabled. However, this can be confusing if no
message pops up
( https://steamcommunity.com/app/70300/discussions/0/3039355280230178910/ )
. So I've made it so that a text box will pop up when they get kicked
out.
This makes it so gamemode(teleporter) will always do an animation, even
if the game is already in TELEPORTERMODE.
I used this script to test:
gamemode(teleporter)
delay(5)
gamemode(teleporter)
delay(5)
gamemode(teleporter)
In 2.2, this script starts the map menu bringing-up animation three
times.
In previous 2.3, this script starts the map menu bringing-up animation
once, but then the next gamemode(teleporter) immediately finishes the
animation, and the third gamemode(teleporter) does nothing.
This commit restores it to 2.2 behavior.
This makes it so it's not even possible to stay on the TELEPORTERMODE
screen by opening the map while it's being brought down. It also makes
it so the map animation is able to be canceled when being brought up
just by opening the map and closing it.
Fixes#833.
This restores it to 2.2 behavior, where the cutscene bars timer also
ticked in TELEPORTERMODE. It was a 2.3 regression that the cutscene bars
timer didn't tick there.
This makes it so if you manage to get stuck in TELEPORTERMODE when a
cutscene ends, the cutscene won't be stuck on untilbars() waiting for
the cutscene bars to go away, since the cutscene bars timer now ticks.
Also, add a sync parameter to avoid calling syncfs too often.
Calling syncfs twice in a row is both inefficient and leads to errors
displaying twice. This allows us to bypass it when saving unlock.vvv as
part of savestatsandsettings.
This object basically had no reason to exist... it was just more verbose
to use, which really reminded me of Java. Anyway, this is the last thing
named after the editor for no reason when it should be a part of the
customlevelclass, so I moved its attributes to customlevelclass.
This fixes the fact that the name of the singular type is plural, but
the name of the plural array is singular. Which has always annoyed me,
too. Also this makes it more clear that custom entities don't have much
to do with the editor.
That's what it is - it's an entity in a custom level. Not something to
do with the editor, necessarily. Like before, the name of the XML
element will remain the same.
That's what edlevelclass is... so that's what it should be named. (Also
removes that "ed", too, making this less coupled to the in-game editor.)
Unfortunately, for compatibility reasons, the name of the XML element
will still remain the same.
CustomLevels.h now uses 4-space indents - like all other space-indented
files - instead of 2-space indents. This has bugged me for a while and I
decided to just fix it now.
This is a pretty hefty commit! But essentially, I made a new editorclass
object, and moved all functions and variables that only get used in the
in-game level editor to that class. This cleanly demarcates which things
are in the editor and which things are just general custom level stuff.
Then I fixed up all the callers. I also fixed up some NO_CUSTOM_LEVELS
and NO_EDITOR ifdefs, too, in several places.
As far as I can tell, this function has never been implemented, and only
existed in this header file. FILESYSTEM_getLevelDirFileNames() already
exists (well, used to exist; it's been changed and renamed to
FILESYSTEM_enumerateLevelDirFileNames()), so I'm removing this now.
This accompanies the editor.cpp -> CustomLevels.cpp change; I'll be
splitting out the editor functions in the next commit. The name of the
include guard has been changed as well, but not anything else.
This moves editorrenderfixed(), editorrender(), editorinput(),
editorlogic(), and their associated functions to a new file named
Editor.cpp - which is exactly what it says on the tin; it stores all the
functions related to the actual in-game editor loop. Also, the existing
editor.cpp has been renamed to CustomLevels.cpp.
All XML functions now check the return value of
tinyxml2::XMLDocument::Error() after each document gets loaded in to
TinyXML-2. If there's an error, then all functions return. This isn't
strictly necessary, but printing the error message that TinyXML-2 is the
bare minimum we could do to be useful.
Additionally, I've standardized the error messages of missing or
corrupted XML files.
Also, the way the game went about making the XML handles was... a bit
roundabout. There were two XML handles, one for the document and one for
the root element - although only one XML handle suffices. So I've
cleaned that up too.
I could've gone further and added error checking for a whole bunch of
things (e.g. missing elements, missing attributes), but this is good
enough.
Also, if unlock.vvv or settings.vvv don't exist yet, the game is
guaranteed to no-op instead of continuing with the function. Nothing bad
seems to happen if the function continues, but the return statements
should be there anyway to clearly indicate intent.
If settings.vvv doesn't exist, loadsettings() calls savesettings(), but
savesettings() already prints a message if settings.vvv doesn't exist.
So then the output would look like
No settings.vvv found. Creating new file
No settings.vvv found
Which is clearly redundant.
The same thing happens with unlock.vvv, but in that case the following
prints instead
No unlock.vvv found. Creating new file
No Stats found. Assuming a new player
I will need to be able to return from this function if there's an XML
error, otherwise writing out the control flow manually gets really
nasty. And while I'm at it, it's some a nice de-duplication as well.
To do this, we create a temporary struct that bundles up all the
information we want for the summary, and pass it in to the intermediate
load function.
Furthermore, we can get rid of reading map.finalstretch - it affects
nothing. map.finalmode is still needed, however, because of the usage of
map.area().
Previously, Flip Mode rendering had to be complicated and allocate
another buffer to call FlipSurfaceVerticle, and it was just a mess.
Instead, why not just do SDL_RenderCopyEx, and let SDL flip the screen
for us? This ends up pretty massively simplifying the rendering code.
`-forcecolor` will force color to be on. `-nocolor` will force color to
be off.
And just because I'm a nice person, I've also added British versions of
those flags. As a treat.
This includes the bold as well.
INFO is just default, WARN is yellow, ERROR is red.
We try to automatically detect if the output is a TTY (and thus supports
colors), and don't emit colors if so. Windows 10 supports ANSI color
codes starting with a specific build, but we don't care to emit whatever
garbage Microsoft invented for builds older than that.
This is because the y-position of the graphics.onscreen() check was a
little too high. Then their name (under Beta Testing) would suddenly
disappear too early. You'd have to look real close to spot it, but it
does happen. It's cuz the credits are all kinda hardcoded, which is
probably bad, but fixing that would have to come later...
I talked with Ethan earlier about this. For 2.3, he wanted me in GitHub
contributors (well, still separate from the rest), to really highlight
the source-code-release community-driven nature of 2.3, but he said it'd
be fine to put me in C++ credits in 2.4.
The RWops stuff isn't a part of any standard PhysFS package (and given
that it explicitly wraps around SDL I'm not sure how you _would_ package
it). So we need to get the physfsrwops.h include in if
BUNDLE_DEPENDENCIES is off, otherwise this results in a compile-time
include-not-found failure.
Additionally, I've placed the PhysFS RWops stuff in their own extras/
folder, so none of the other PhysFS stuff gets included in a
-DBUNDLE_DEPENDENCIES=OFF build.
The game will freeze the player immediately if they release a
directional button within 3 frames of pressing it. Similar to flipping,
this involves global state, and will only apply to the first player
entity.
Closes#484
Flipping only applies momentum to the player entity currently being
processed. This normally wouldn't be a problem. However, flipping
involves global state, and only one flip can occur per frame. This means
that additional player entities don't get this boost of momentum, which
feels somewhat unnatural during gameplay.
This commit fixes this by splitting flip logic out of the loop over
player entities, and applying the flip momentum to all player entities.
We need to check for graphics.setflipmode, not graphics.flipmode,
because graphics.flipmode only gets assigned at the end of the frame
(due to the deferred callback). Otherwise, returning from the options
menu would always turn flag 73 on, which would make you ineligible to
get the Flip Mode trophy, even if you're in Flip Mode.
Originally this started as a "deduplicate a bunch of duplicated code in script commands" PR,
but as I was working on that, I discovered there's a lot more that needs to be done than
just deduplication.
Anything which needs a crewmate entity now calls `getcrewmanfromname(name)`, and anything which
just needs the crewmate's color calls `getcolorfromname(name)`. This was done to make sure that
everything works consistently and no copy/pasting is required. Next is the fallback; instead of
giving up and doing various things when it can't find a specific color, it now attempts to treat
the color name as an ID, and if it can't then it returns -1, where each individual command handles
that return value. This means we can keep around AEM -- a bug used in custom levels -- by not
doing anything with the return value if it's -1.
Also, for some reason, there were two `crewcolour` functions, so I stripped out the one in
entityclass and left (and modified) the one in the graphics class, since the graphics class also
has the `crewcolourreal` function.
If `setactivitytext` was the last line in a script,
the command would index the vector out of bounds.
I also modified the formatting to keep consistent
with the rest of the codebase.
These commands will change the colour and text of the next
activity zone that gets spawned. `setactivitycolour` takes all
textbox colors, and `setactivitytext` will take the text on
the next line. These commands were designed this way
to avoid breaking forwards compatibility.
When an activity zone is spawned through the
use of `createactivityzone`, and `i` is 35,
then it'll change the activity zone text to
"Press ENTER to interact".
On Emscripten, SDL_Delay is implemented as a busy loop. In addition,
everything happens on a single thread. This effectively means that
you have to let Emscripten manage the main loop, since if you do it
yourself the browser will just be frozen.
Otherwise, the new arguments to destroy(), which are 'moving' and
'disappear', would be thrown away by the simplified parser. Let's create
less work for ourselves to do and simply not have a hardcoded list of
allowed arguments for destroy() in the parser.
destroy(platforms) has been bugged since 2.0. The problem with it is
that it removes the platform entity, but doesn't remove its block. This
results in essentially turning the platorm invisible and stopping it
from moving.
This error should be fixed, but some levels (including my own) rely on
the invisible platform trick. So instead, the fixed version will be
implemented under a different name, destroy(moving).
There's also another problem with destroy(platforms), which is that the
name is misleading and it doesn't additionally destroy disappearing
platforms. I would also fix this, but in order to not run the risk of
breakage, it will have to be implemented under a different name, too. So
this will be destroy(disappear). As an added benefit, it's also more
granular to have platform-destroying functions under different names
than it is to consolidate them under the same name.
When I added the two-frame delay fix, I didn't realize that Game had a
roomchange variable that was being used as a temporary variable here.
Now that it's fully spelled out and obvious (just look at the top of
gamelogic()), I realize that the variable exists and is being used, and
other readers will realize it's being used too - so now that I know it
exists, I can axe the screen_transition variable I added in favor of
using roomchange instead.
The purpose of this variable was to keep track of if gamelogic() called
map.gotoroom() at any point during its execution. So map.gotoroom()
always unconditionally set it to true, and then gamelogic() would check
it later.
Well, there's no need to put that in a global variable and do it like
that! It makes it less clear when you do that.
So what I've done instead is made a temporary macro wrapper around
map.gotoroom() that also sets roomchange to true. I've also made it so
any attempt to use map.gotoroom() directly results in failure (and since
then using map.gotoroom() in the wrapper macro would also fail, I've had
to make a gotoroom wrapper function around map.gotoroom() so the wrapper
macro itself doesn't fail).
This is a temporary vector that only gets used in mapclass::gotoroom().
It's always guaranteed to be cleared, so it's safe to move it off.
I'm fine with using references here because, like, it's a C++ STL vector
anyway - when we switch away from the STL (which is a precondition for
moving to C), we'll be passing around raw pointers here instead, and
won't be using references here anyway.
This is a temporary variable that doesn't need to be on Game. It is
guaranteed to be initialized every time mapclass::gotoroom() gets
called, so it's safe to move it off.
Enemy/platform bounds are intended to not be drawn if they cover the
whole screen, since that's what their default bounds are.
However, the code inadvertently made it so if ANY of the bounds touched
a screen edge, the bounds wouldn't be drawn. This is because the
conditionals used "and"s instead of "or"s. The proper way to write the
positive conditional is "x1 is 0 and y1 is 0 and x2 is 320 and y2 is
240", and when you invert that conditional, you need to also invert all
"and"s to be "or"s. This is not the first time that the game developers
failed to properly negate conjunctional statements...
This is to make it so RNG is deterministic when played back with the
same inputs in a libTAS movie even if screen effects or backgrounds are
disabled.
That way, Gravitron RNG is on its own system (seeded in hardreset()),
separate from the constant fRandom() calls that go to visual systems and
don't do anything of actual consequence.
The seed is based off of SDL_GetTicks(), so RTA runners don't get the
same Gravitron RNG every time. This also paves the way for a future
in-built input-based recording system, which now only has to save the
seed for a given recording in order for it to play back
deterministically.
Otherwise, levels could leave stale arguments in the array, and then the
behavior of another level loaded right after might end up being
different because of that.
This is done for consistency with Terry's patrons, which are sorted by
first name and not last.
Also some people go with their usernames and so don't have a last name
to speak of, which ended up being pretty weird.
Kai is my last name. Elizabeth is my middle name. I went with my middle
name as last name for a while before figuring out what I wanted my last
name to be.
Third time's the charm.
The fundamental problem with the previous attempts was that they ended
up saying arguments existed due to stale `words` anyway. So to actually
know if an argument exists or not, we need to assign to `argexists` _as_
we parse the line.
And make sure to take care of that last argument too.
Also I thoroughly tested this this time around. I'm done pulling my hair
out over this.
Ever since tilesheets got expanded, custom levels could use as many
tiles as they wanted, as long as it fit under the 32-bit signed integer
limit.
Until 6c85fae339 happened and they were
reduced to 32,767 tiles.
So I'm being generous again and changing the type of the contents array
(in mapclass and editorclass) back to int. This won't affect the
existing tilemaps of the main game, they'll still stay short arrays. But
it means level makers can use 2 billion tiles once again.
This lets users place down tiles above 1199 in Direct Mode, if their
tilesheet has more than 1200 tiles.
I don't like the copy-pasted code here but it'll have to make do.
If you use Lab tilecol 6, you get the rainbow background. However, this
is unintended, because the associated autotiling is... not very good.
To combat that, Ved disallows using the Lab rainbow background outside
of Direct Mode. We will follow Ved here and only allow switching to the
rainbow background if you're in Direct Mode. Also make sure if someone
is disabling Direct Mode with the rainbow background that it gets reset
properly.
The main game used a set of copy-pasted code to set the music of each
area. There WAS some redundancy built-in, but only three rooms in each
direction from the entrance of a zone.
Given this, it's completely possible for players to mismatch the music
of the area and level. In fact, it's easy to do it even on accident,
especially since 2.3 now lets you quicksave and quit during cutscenes.
Just play a cutscene that has Pause music, then quicksave, quit, and
reload. Also some other accidental ways that I've forgotten about.
To fix this, I've done what mapclass has and made an areamap. Except for
music. This map is the map of the track number of every single room,
except for three special cases: -1 for do nothing and don't change music
(usually because multiple different tracks can be played in this room),
-2 for Tower music (needs to be track 2 or 9 depending on Flip Mode),
and -3 for the start of Space Station 2 (track 1 in time trials, track 4
otherwise).
I've thoroughly tested this areamap by playing through the game and
entering every single room. Additionally I've also thoroughly tested all
special cases (entering the Ship through the teleporter or main
entrance, using the Ship's jukebox, the Tower in Flip Mode and regular
mode, and the start of Space Station 2 in time trial and in regular
mode).
Closes#449.
2.3 has a regression where if you move back and forth between a zone,
you can get the wrong music playing in a zone. An example is the
Overworld and Lab. Just walk in to the Lab and immediately walk back
out, and you'll get Potential for Anything playing in the Overworld.
This regression was caused by facb079b35.
That commit removed assigning -1 to currentsong when a fadeout was
called.
Basically, the previous behavior was: currentsong is 4, we enter Lab and
nicechange gets queued to 3 but currentsong gets set to -1, then going
back nicechange gets queued to 4 again.
However, if we don't assign -1, then going back will keep nicechange at
3. Why? Because niceplay() checks for currentsong before assigning
nicechange. If currentsong is still the same then it doesn't assign
nicechange.
To fix this, just always unconditionally assign nicechange.
If spawned as a custom enemy (createentity entry 56), or spawned outside
of the rooms they spawn in in the main game, they will repeatedly clone
themselves every frame, which profusely leaks memory. In fact it quickly
causes a crash in 2.2 and previous, but 2.3 fixes that crash, so it just
keeps spawning enemies endlessly, which eventually lags the game, and
eventually can out-of-memory your system (bad!).
The problem is those movement types rely on entclass::setenemyroom() to
change their `behave` to be 11 or 13. Else, the new entity created will
still have `behave` 10 or 12, which will create ANOTHER entity in the
same way, and so on, and so forth.
So to fix this, just make it so if an enemy is still `behave` 10 or 12
by the end, then, just set it to -1. That way it'll stay still and won't
cause any harm.
I considered setting the `behave` to 11 or 13 respectively, but, that's
probably going farther than just fixing a memory leak, and anyways, it's
not that much useful for me as a custom level maker, and the entities
spawned aren't really controllable.
In order to let callers provide their OWN callback functions through the
callback function WE provide to PhysFS, we casted the function pointer
to a void pointer.
Unfortunately, this is apparently undefined behavior... if your compiler
doesn't have an extension for it. And most compilers on most
architectures do. (In fact compilers on POSIX systems most certainly
have it due to dlsym() returning a void* which could actually be a
pointer to a function sometimes.)
But imo, it's better to be safe than sorry in this regard. Especially
when given GCC's approach to optimizing int + 100 > int (spoilers: they
remove it entirely! It's faster, but also broken!).
I've decided to wrap it in a struct. And as a nice side effect, if we
ever need more data to be passed through... well we already have this
struct.
Technically, it's also standards-compliant to cast a _pointer to_ a
function pointer to a void pointer. But that extra layer of pointer
indirection would get real confusing to conceptualize real fast (or at
least is more confusing than just putting it in a struct).
Since you've been able to resume music stopped by stopmusic() with
resumemusic(), if a track was stopped by stopmusic(), the unfocus pause
itself would end up resuming the track when regaining focus.
The solution is to simply check for if music.currentsong is -1 or not.
So, platv is a room property that controls the speed of custom entity
platforms in the room (unless, of course, they're created with
createentity). Problem is, this is how 2.2-and-previous coding standards
were:
ed.level[game.roomx-100+((game.roomy-100)*ed.maxwidth)]
Overly long, verbose, not entirely clear unless you already know what it
means? Copy-pasted over and over due to all of the above? Surely a
recipe for not making any coding errors!
Ironically enough, copy-pasting is basically the best approach here
(short of refactoring the whole thing, like I did in
945d5f244a), since if you don't ACTUALLY
copy-paste and just re-type it on your own, you'll end up making more
mistakes. Like what happened here:
ed.level[game.roomx-100+((game.roomy-100)*ed.mapwidth)].platv
Do you see the mistake...? Yeah, mapwidth (with a P) instead of maxwidth
(with an X). You'd have to look closely to find it.
So what does this mean for platv? Well, it means that it multiples the
y-coordinate of the room by the map width instead of the max width (20),
like every other room property. So that means if your map width is less
than 20, like say, map width 10, the platv value for (2,2) will be
stored in (2,1)'s room properties instead of (2,2)'s. Because if you go
off of map width, the room index for (2,2) is 2 + 2 * 10 = 22, but if
you go off of max width, the room index for (2,1) is 2 + 1 * 20 = 22.
Now this wouldn't be bad, except for another 2.2-and-previous
standard... kind of just not exposing things directly to the end user.
Whether that's simply not documenting something (as in the case of
ifwarp and warpdir, which by all measures were completely intended to be
used in custom levels but just simply were never known properly until I
discovered how to use them in 2019), or in this case, not giving any way
for the user to fiddle with platv from the in-game editor. Because if
there was a way to do that, and someone decided to test to see if platv
worked okay, they would discover something was up.
So... since I refactored room properties in
945d5f244a, I kind of broke platv by
fixing it. Now levels that relied on platv being the broken way don't
work.
How do I fix it, and thus break it again? Well, I'll do what I did for
scripts - handle the scrambling when reading and writing the level, and
keep things sane at least internally.
Thus: editorclass::load() will unscramble platv data in the right way,
and editorclass::save() will re-scramble platv in the right way too.
To match the option to nuke all main game save data, there is also now
an option to nuke all custom level save data separately (which is just
all custom level quicksaves, along with stars for level completion). It
has its own confirmation menu too. It does not delete any levels from
the levels folder.
Custom level quicksaves are NOT affected by the clear data menu, so the
player should be able to delete quicksaves this way. The quicksave
confirmation menu now has an extra option to delete the save (and that
option also has its own confirmation menu before deleting).
This error case can happen, but if it does, non-console users get an
ERROR page with no further information. So use setLevelDirError if this
failure mode happens. And Menu::errorloadinglevel needs to be changed to
accomodate that.
Not sure why the original implementation decided to do things this way
instead of snprintf'ing a path to the .zip itself. Otherwise, if the
level is from data.zip, PHYSFS_getRealDir() will return the path of
data.zip, which then fails to mount for separate reasons.
Since createentity() started accepting p1/p2/p3/p4 arguments, it now
unconditionally passes in whatever arguments were present there
previously, when there weren't any before.
This can lead to unexpected behavior when selectively using and then
omitting p1/p2/p3/p4 arguments.
Also, plenty of existing levels already only use the 5-argument version
of createentity(). And createcrewman() can take up to 6 arguments at
once. It's not far-fetched that an existing level could createentity()
right after doing a 6-argument createcrewman(), which would lead to a
different behavior than in 2.2 and previous.
So instead, instead of checking if `words[index]` is an empty string (it
only sets the string to be empty if there are enough argument separators
on the line), ACTUALLY check if it's empty. I've added a static array
(no need for it to be exported) that keeps track of this. createentity()
now checks for that instead of `words`.
It's possible to get one page of levels by removing all the built-ins,
either by removing them directly from data.zip or by putting files with
the same filenames as them in your level folder that don't contain
nothing.
And hey, there's already a check for if no levels exist at all, so why
not check for this too?
Previously, you would only get the trinket completion star if you got
the exact same amount of trinkets as there are custom entity trinkets in
the level file. But if you got more (say, if the level spawned extra
"bonus trinkets"), you wouldn't be able to get the star.
This is true of the custom crewmate case as well, but I've decided to
not change that case, because there are still downsides to the resulting
behavior and it's better to just leave it alone because it's rare for it
to happen anyways.
Since custom levels have gained the functionality to show trinkets on
the minimap, it's nice to just save the showtrinkets variable directly
to the save file, without having to make level makers handle it
themselves.
If you have unfocus pause off, and unfocus audio pause off, then this command will go into effect.
When it's set to on, the audio will pause when you unfocus the game. When it's set to off, the
audio will not. This is different from the setting, and gets saved to the save file.
If a zip file is improperly structured, a message will be displayed when
the player loads the level list.
This will only display the last-displayed improper zip, because there
only needs to be one displayed at a time. Also because doing anything
more would most likely require heap allocation, and I don't want to do
that.
This will wrap text on-the-fly, since I will be introducing text that
needs to be wrapped whose length we can't know in advance. (Or we can,
but, that'd be stupid.)
I took the algorithm from Dav999's localization branch, but it's not
like it's a complicated algorithm in the first place. Plus I think it
actually handles words that get too long to fit on a single line better
than his localization branch. The only difference is that I removed all
the STL, and made it more memory efficient (unlike his localization
branch, it does not copy the entire string to make a version with
newline separator characters).
This macro needs to be used because Clang is stupid and doesn't let you
use /* fallthrough */ comments like GCC does. However, if GCC is too old
(as is the case on CentOS 7), then it won't recognize __has_attribute
either.
Some people prefer the 2.2 behavior where unfocusing pauses the game,
but the music still plays. One such person is Trinket9 on the VVVVVV
Discord server, who wanted it that way.
The reason audio pausing was added in the first place was to prevent
desyncing music in levels with cutscenes that synced to music. Rather
than reverting it, let's add this option instead.
Similar to disabling the elephant flashiness, at least one
photosensitive person has told me the flashy color animation makes their
eyes kind of hurt a little bit. Also it screws up the compression really
badly when they record (especially the green noisy tiles!).
The colors will still cycle, but the individual animations within each
color will be completely static.
It's quite rude to close the game. Especially if the user does not use
the console. They won't know why the game closed.
Instead, just return -1. All usages of font_idx() should be and are
bounds checked anyways. This will result in missing characters, but,
it's not like the characters had a font image in the first place,
otherwise we wouldn't be here. And if the user sees a bunch of
characters missing in their font, they'll probably work out what the
problem is even without having a console. And it's still far better than
abruptly closing the game.
And use WHINE_ONCE to prevent spamming the console.
Let's say you have a zip named LEVELNAME.zip, but the only .vvvvvv file
it contains is NOTLEVELNAME.vvvvvv. This zip would end up printing both
the 'LEVELNAME.vvvvvv is missing' and 'It has .vvvvvv file(s) other than
LEVELNAME.vvvvvv' messages, even though we already know there's
something wrong with the zip, and the 'other level files' message is
redundant, since in this case the problem here is simply just the
.vvvvvv file being named the wrong way.
The 'other level files' message is only intended to be printed when
LEVELNAME.vvvvvv *does* exist, but there's additional .vvvvvv files in
the zip on top of that, so don't print this message if LEVELNAME.vvvvvv
exists.
Since colors going into FillRect() need to be in BGR format, we need to
use getBGR instead. (Well, actually, it gets passed in RGB, but then at
some point the order gets switched around, and, really, this game's
masks are all over the place, I'm going to fix that in 2.4.)
This can happen if you select an option in a menu that (A) returns to
the previous menu and (B) saves settings. If the settings save fails,
this will create another menu on the same frame that cycles the tower BG
after it's already been cycled for that frame. Examples are the slowdown
and glitchrunner menus.
I could fix this by creating a new function that copy-pastes all of
Game::savestatsandsettings_menu() except for the map.nexttowercolour()
at the end. But that's copy-pasting code.
Instead what I've done is added a variable to signal if the color has
already been cycled this frame, so we don't cycle it again. This also
covers cases of possible double-cycling in the future as well.
This is because the fade delay did not last long enough.
I was under the mistaken impression that the fade animation lasts for 15
frames. However, this does not account for the fact that the offset of
each fade bar is dependent on RNG, and the worst case scenario is that
they have an offset of 96 pixels (in the opposite direction of the
fade).
The actual fade animation timer accounts for the worst case scenario, so
the fade animation actually lasts for (320 pixels plus 96 pixels is 416
pixels, 416 pixels divided by 24 pixels per frame equals 17.333...
frames, but since the actual timer keeps adding/subtracting 24 pixels
per frame until it passes the 416-pixel threshold, that gets rounded up
to...) 18 frames.
And an extra frame to make it so deltaframe interpolation doesn't
suddenly stop on the last deltaframes before the screen is completely
black.
I also need to draw the screen black on the map screen when glitchrunner
mode is off, if there's a fadeout going on. Else that would introduce
yet another frame flicker.
This fixes a bug where the player would always be facing right if they
were loading in for the first time. This essentially made them always
ignore the facing direction set in the save file if the facing direction
was leftwards.
The problem is facing direction only gets set in map.resetplayer(), but
if loading in for the first time, that path is never taken (unless you
are loading a main game quicksave that's inside a tower). The solution
is to always reset the player, even after creating them for the first
time.
This fixes being able to re-trigger the fadeout while a fadeout is
already happening. It also fixes being able to enter playtesting during
the fadeout, which means the level now has a fadeout you normally can't
do in actual gameplay.
There's nothing to interpolate. It moves at one pixel per frame. And
interpolating sometimes results in the box being short by 1 pixel to
cover the whole screen on deltaframes, so if you stand on the right edge
of the screen and have a translucent sprite, it will quickly draw over
itself many times, and it looks glitchy. This commit fixes that bug.
Previously, turning glitchrunner mode on essentially locked you to
emulating 2.0, and turning it off just meant normal 2.3 behavior. But
what if you wanted 2.2 behavior instead? Well, that's what I had to ask
when a TAS of mine would desync in 2.3 because of the two-frame delay
fix (glitchrunner off), but would also desync because of 2.0 warp lines
(glitchrunner on).
What I've done is made it so there are three states to glitchrunner mode
now: 2.0 (previously just the "on" state), 2.2 (previously a state you
couldn't use), and "off". Furthermore, I made it an enum, so in case
future versions of the game patch out more glitches, we can add them to
the enum (and the only other thing we have to update is a lookup table
in GlitchrunnerMode.c). Also, 2.2 glitches exist in 2.0, so you'll want
to use GlitchrunnerMode_less_than_or_equal() to check glitchrunner
version.
Two problems: the fRandom() range was from 0..36, but that's 37
characters, not 36. And the check to sort the lower 26 values into the
Latin alphabet used a 'lesser-than-or-equal-to 26' check, even though
that checks for the range of values of 0..26, which is 27 letters, even
though the alphabet only has 26 letters. So just drop the equals sign
from that check.
It was checking for .vvv-mnt-temp-XXXXXX/LEVELNAME.vvvvvv instead of
LEVELNAME.vvvvvv. When PhysFS enumerates the folder, it only gives us
LEVELNAME.vvvvvv, and not .vvv-mnt-temp-XXXXXX/LEVELNAME.vvvvvv.
This fixes a regression that desyncs my Nova TAS after re-removing the
1-frame input delay.
Quick stopping is simply holding left/right but for less than 5 frames.
Viridian doesn't decelerate when you let go and they immediately stop in
place. (The code calls this tapping, but "quick stopping" is a better
name because you can immediately counter-strafe to stop yourself from
decelrating in the first place, and that works because of this same
code.)
So, the sequence of events in 2.2 and previous looks like this:
- gameinput()
- If quick stopping, set vx to 0
- gamerender()
- Change drawframe depending on vx
- gamelogic()
- Use drawframe for collision (whyyyyyyyyyyyyyyyyyyyyyyyyyyy)
And now (ignoring the intermediate period where the whole loop order was
wrong), the sequence of events in 2.3 looks like this:
- gamerenderfixed()
- Change drawframe depending on vx
- gamerender()
- gameinput()
- If quick stopping, set vx to 0
- gamelogic()
- Use drawframe for collision (my mind has become numb to pain)
So, this means that all the player movement stuff is completely the
same. Except their drawframe is going to be different.
Unfortunately, I had overlooked that gameinput() sets vx and that
animateentities() (in gamerenderfixed()) checks vx. Although, to be
fair, it's a pretty dumb decision to make collision detection be based
on the actual sprites' pixels themselves, instead of a hitbox, in the
first place, so you'd expect THAT to be the end of the dumb parade. Or
maybe you shouldn't, I don't know.
So, what's the solution?
What I've done here is added duplicates of framedelay, drawframe, and
walkingframe, for collision use only. They get updated in gamelogic(),
after gameinput(), which is after when vx could be set to 0.
I've kept the original framedelay, drawframe, and walkingframe around,
to keep the same visuals as closely as possible.
However, due to the removal of the input delay, whenever you quick stop,
your sprite will be wrong for just 1 frame - because when you let go of
the direction key, the game will set your vx to 0 and the logical
drawframe will update to reflect that, but the previous frame cannot
know in advance that you'll release the key on the next frame, and so
the visual drawframe will assume that you keep holding the key.
Whereas in 2.2 and below, when you release a direction key, the player's
position will only update to reflect that on the next frame, but the
current frame can immediately recognize that and update the drawframe
now, instead of retconning it later.
Basically the visual drawframe assumes that you keep holding the key,
and if you don't, then it takes on the value of the collision drawframe
anyway, so it's okay. And it's only visual, anyway - the collision
drawframe of the next frame (when you release the key) will be the same
as the drawframe of the frame you release the key in 2.2 and below.
But I really don't care to try and fix this for if you re-enable the
input delay because it's minor and it'd be more complicated.
In the past, people have reported having glitched levels where they
can't get the trinket star or can't complete the level because the
number of trinkets or crewmates is one higher than what can be obtained
in the level.
How did this happen? Well, it turns out that if you place an entity, and
then resize the level to be smaller, that entity still exists. This is
inconsequential for most entities, but if the entity is a trinket or
crewmate, that entity is still counted towards the number of trinkets or
crewmates in the level.
One fix would be to just remove entities whenever the level is
downsized, but then if someone accidentally downsizes the level and
wants to go back, that entity will be gone. Plus, it would be
inconsistent with tiles, because tiles don't get removed when you
downsize the level. Also, it wouldn't fix existing levels where people
have managed to place trinkets or crewmates out of bounds.
So instead, ed.numtrinkets() and ed.numcrewmates() should simply ignore
trinkets and crewmates that are outside the playable area. That way,
levels with glitched trinkets and crewmates can still be completed, and
can still be completed with the trinket star.
This fixes a regression where you're unable to activate activity zones
in in-editor playtesting if your interact button is not separate from
the map button.
When I originally did #743, I didn't have an option to set the bind to
be non-separate, so I removed this logic without adding a
game.separate_interact check. But when I added the option, I overlooked
this code, and so this regression happened. Whoops.
Not every music path will trip the quick_fade bool that resets the timer to
500ms, so we need to do this as soon as it's asked of us. This fixes the fade
when quitting to the main menu.
Fixes#764
Without this you end up with two problems:
- Fades will start past their fade time, causing it to just not fade at all
- Fades will start in the middle of their fade time, causing dramatic changes
in volume that are unintentional
The fade system already preserves the volume that music is playing during a
previous fade, so we can always reset the timer and get a good result.
Part of #764
This fixes one of two desyncs in my Nova TAS.
The problem is that by adding two frames of edge-flipping to vertically
moving platforms, Viridian's framedelay is updated for one extra frame
after they step off of a vertically-moving platform. This then messes up
Viridian's drawframe for the rest of the TAS until they die in a
drawframe-sensitive trick.
The solution here is to only set the visual onroof/onground to 1
instead. The logical onroof/onground is still 2, so players still have
two frames of edge-flipping off of vertically-moving platforms - it just
won't really look like it (not that you could easily tell anyway).
- use fseeko and ftello like FreeBSD in tinyxml2
- use current directory as basePath if NULL (OpenBSD doesn't actually support this feature it is disabled via a patch in their ports)
In order to help players spot the difference between outlined text and
non-outlined text, we now outline the text outline text itself (if text
outline is enabled, of course). But drawing the outline alone doesn't
stand out enough, so we have to draw a solid backing against the text as
well, in order to properly show the contrast.
This fixes a regression where you're able to start flipped by restarting
and then holding ACTION.
This happens because when the game resets all variables, it turns
hascontrol back on (because of hardreset()). However, this is handled in
the input function, and it's handled before player input is handled, so
the player is able to get 1 frame of being able to flip after a time
trial resets.
Why didn't this happen in 2.2? Because resetplayer() in 2.2 would set
lifeseq to 10, as if the player had died. However, this is inconsistent,
because loading in to the game for the first time would not result in a
lifeseq of 10. So, in 2.2, restarting the time trial would remove that 1
frame of being able to flip because of lifeseq, while 2.3 doesn't set
lifeseq because the player hasn't died.
I could have fixed this by setting lifeseq in the time trial restart
code, but I decided to just set hascontrol to false instead.
Fixes#770.
In earlier 2.3, if the roomname was empty, Dimension VVVVVV was used
instead. However, instead of doing that, it's better to just use the
hiddenname instead. Both because it's less hardcoded, and some rooms
have hidden names that aren't Dimension VVVVVV.
This makes the text much more readable against certain backgrounds (if
you have text outline enabled), especially against the Warp Zone
background (when you start in "This is how it is").
If you enter the Secret Lab from the title screen, all rooms will be
explored. However, if you enter the Secret Lab via the Secret Lab
entrance cutscene (epilogue), not all rooms will be explored, which is
inconsistent.
To do this, just do an SDL_memset() for the entersecretlab script
command.
SDL_memset() conveys intent better and is snappier than using a
for-loop. Also, using SDL_memset() to explore all rooms is more
future-proof, in case the size of map.explored were to change in the
future, and it's more conducive to optimization.
However, the `i` variable has to be explicitly set because it was
previously used here, but it's much better that it's explicitly set here
rather than being subtlely hidden in the inner for-loop initialization.
This is more future-proofing than anything else. The position of the
indicators is just the x-position of the gravitron square divided by 10,
but the gravitron squares will always only ever move at 7 pixels per
frame - so the distance an indicator travels on each frame will only
ever be at most 1 pixel. But just in case in the future gravitron
squares become faster than 10 pixels per frame, their indicators will be
interpolated as well.
When rollcredits is ran during in-editor playtesting, all unsaved data
is lost. To prevent this, just return to the editor if rollcredits is
ran, with a note saying "Rolled credits".
The text box drawn at the bottom of the map screen isn't wide enough, so
it's possible to see the corners on the right side of the text box if
you have custom graphics like I do.
The solution is to increase the width of the text box by one tile.
The game automatically writes settings to disk after any other setting
is changed, so it should do the same whenever the user changes
controller keybinds.
For consistency, the Viridian squeak will now play whenever you start
editing a level description field, or finish editing it (either by
pressing Esc or Enter).
If a level zip is named LEVELNAME.zip, the level file inside it must
also be named LEVELNAME.vvvvvv, else custom assets won't work.
This is because when we mount the zip file, we simply add
LEVELNAME.vvvvvv to the levels directory. Then whenever we load
LEVELNAME.vvvvvv, we look at the filename, remove the extension, and
look for the assets inside the zip of the same name, LEVELNAME.zip.
As a result, if someone were to make a level zip with assets but
mismatch the filename, the assets wouldn't load. Furthermore, if someone
were to add extra levels in the same zip, they wouldn't have any assets
load for them as well, which could be confusing.
To make things crystal-clear to the user, we now filter out any zips
that have incorrect structures like that, and print a message to the
terminal. Unfortunately nothing gets shown for non-terminal users, but
at least doing this and filtering out the zips is less confusing than
letting them through but with the issues mentioned above.
FILESYSTEM_mountAssets() has a big comment describing the magic numbers
needed to grab FILENAME from a string that looks like
"levels/FILENAME.vvvvvv".
Instead of doing that (and having to write a comment every time the
similar happens), I've written a macro (and helper function) instead
that does the same thing, but clearly conveys the intent.
I mean, just look at the diff. Using VVV_between() is much better than
having to read that comment, and the corresponding SDL_strlcpy().
This is so it can be reused without having to copy-paste.
generateBase36() is guaranateed to completely initialize and
null-terminate the buffer that is passed in.
This fixes a bug where the player's y-position would be incorrect if
they loaded a save that was on a conveyor and it was their first time
loading in since the game was opened.
This is because on the first load, the game creates a new player entity,
but on subsequent loads, the game re-uses the player entity. Subsequent
loads use mapclass::resetplayer(), which already has the newxp/newyp
fix, but as for the first time, the game does not set newxp/newyp.
So just set newxp/newyp, like in mapclass::resetplayer().
Upon further discussion it was decided to keep the soundtrack as originally
shipped, instead of changing it after the fact.
This reverts commit cf51379097.
There is a pattern in the Super Gravitron that is meant to "staircase",
similar to the Gravitron in Intermission 2. Something like:
[]
[]
[]
[] []
[] []
Unfortunately, due to an oversight, this pattern can only ever produce 1
square or 4 squares, which look out of place.
Both gravitrons are state machines (of course). States 20 and 21 in the
Super Gravitron are this staircase pattern (state 20 spawns the squares
on the left, state 21 spawns the squares on the right).
The only way states 20 and 21 can be reached is through state 1, and the
only way state 1 can be reached is through state 3. The only way state 3
can be reached is through states 28, 29, 30, and 31.
In states 20 and 21, the variable used to keep track of the amount of
squares spawned is swnstate4. However, states 28, 29, 30, and 31 all end
up using swnstate4, and at the end of states 28 and 29, swnstate4 will
be 7, and at the end of states 30 and 31, swnstate4 will be 3. This
means if we go to states 20 and 21 after coming from states 28 and 29,
we will only get 1 square, and if we go to states 20 and 21 after coming
from states 30 and 31, we will only get 4 squares.
This can be clearly filed under a failure to reset appropriate state.
What's the solution here? Just reset swnstate4 in state 3, so there will
be 7 squares, as intended. This also fixes the bug for state 22 as well,
which is affected in the same manner.
This fixes an oversight that could lead to confusion by the player.
showtargets is the variable that shows all unexplored teleporters on the
map as a question mark, so players know where to head to to make
progress. However, it previously was not directly saved to the main game
file. Instead, it would be set to true if flag 12 was turned on in the
save file.
How well does flag 12 correlate with showtargets?
Well, the script that turns on showtargets (bigopenworld and
bigopenworldskip) doesn't turn it on. Neither does completing Space
Station 1.
This flag is only turned on when the player activates Violet's activity
zone for the first time.
Therefore, it's entirely possible that a new player could complete Space
Station 1, then save their game, and come back to resume playing later.
When they do come back, the question marks that Violet told them about
won't show up on the minimap, and they'll be confused. They may not know
where to go.
And it is completely unintuitive for them to know that in order to get
the question marks to show up again, they have to not only talk to
Violet, but then save the game again, and reload the save. Especially
since the question marks only show up after you reload the save, and not
when you talk to Violet (because flag 12 is only a proxy for
showtargets, not the actual variable itself).
So what's the solution? Just save showtargets to the save file directly.
If you have invincibility enabled, the tower camera behavior is
inconsistent.
In ascending towers, you can "push" the camera upwards; however you
cannot push it downwards; at least it stays still when it comes up to
you if you stay still. In descending towers, the camera moves quicker
when you're at the bottom of the screen, but it's slower than your
falling speed and quickly loses sight of you; the camera can be pushed
upwards; unfortunately it also does a "bumping" motion if you're
standing still when the camera reaches you, which gets real annoying and
isn't particularly pleasant to look at.
There are two problems, so this does two fixes:
1. Pushing the camera now applies the appropriate counter-offset
depending on the direction of the tower. You can now push the camera
downwards in ascending towers.
2. To fix the "bumping" when the camera reaches you if you stand still,
there are now a 8-pixel-high "gray areas" at the top and bottom of
the screen where the camera simply won't move if you're in them.
Doing these camera offsets instead of simply canceling the movement if
the player is offscreen is a bit ugly... but it works for now.
This is a lot of copy-pasted code, but a little bit of copy-pasting
never hurt anyone...
The keybind to interact with activity zones and teleporters is now
separate from the keybind to open the map, or return to the editor from
in-editor playtesting, or restart a time trial. The keybind is now E,
and the default controller bind is X. No controller button prompts, but
the game didn't have controller button prompts anyways, so whatever.
Doing this now because if people's muscle memory are going to be broken
by not being able to spam the map keybind anymore, at least we can help
a bit by changing the keybind so they can keep spamming it - their
muscle memory is going to be broken anyways.
This option has to be enabled by going to the speedrunner menu options
and selecting "interact button". It is disabled by default.
All prompt text needs to be string-interpolated every time they are
drawn, because it is possible for people to change which interact button
they use in the middle of gameplay, via the in-game options.
Closes#736.
Colors in over-30-FPS mode shouldn't be updating every deltaframe;
mostly to ensure determinism between switching 30-mode and over-30 mode.
I'm going to overhaul RNG in 2.4 anyway, but right now I'm going to fix
this because I missed it.
The RNG of each special text box is stored in a temporary variable on
the text box itself, and only updated if the color uses it (hence the
big if-statement). Lots of code duplication, but this is acceptable for
now.
After the dimension destabilizes, the song that plays is Positive Force.
Which has already been played twice in the game at that point (first in
Tower, then in the Gravitron). Since Piercing the Sky is unused, why not
play a song that the player hasn't heard before? It would also be
musically fitting for the scenario.
The song gets played in two places - one for if you have cutscenes
enabled, and one for if you don't - so we just need to change both of
them.
I asked Terry in Discord DMs if he wanted this change and he approved of
it.
If you have completed No Death Mode, and entered the Master of the
Universe trophy room in the Secret Lab in over-30-FPS mode, it would
appear to start at one position before quickly zipping to another during
the deltaframes.
This is because it updates its position after the initial assignments of
lerpoldxp/lerpoldyp in entityclass::createentity().
Other entities do this too, and what's been done for them is to
copy-paste the lerpoldxp/lerpoldyp updates alongside the xp/yp updates.
However, instead of single-case patching this deltaframe glitch, I've
opted to fix ALL cases by simply moving the lerpoldxp/lerpoldyp
assignments to the end of the function, guaranteeing that all entities
that update their position after the initial assignment in the function
will not have any deltaframe glitches.
Of course, there's still the duplicate lerpoldxp/lerpoldyp updates in
entityclass::updateentities()... I'm not sure what to do about those.
If you had Flip Mode enabled when exiting from in-game options, the game
would flash the in-game options menu as flipped for 1 frame before
returning to the pause menu.
To fix this, just defer the Flip Mode variable assignment to be done at
the end of the frame.
This is a small quality-of-life fix in the same vein as allowing the
player to press Esc in the teleporter menu (which they weren't able to
do in 2.2, either).
This fixes the finalstretch tile shifting persisting if you return to
the main dimension and final_colormode isn't reset properly.
It's possible to do so in the main game by using a teleporter in
finalmode while having the Intermission 1 or 2 companion active.
For custom levels, level makers can make a setup that automatically
turns on finalstretch, goes to finalmode, and then returns to the main
dimension. The only thing being... as a level maker myself, this tile
shifting REALLY doesn't seem useful (and no one has ever used it because
the setup to do so hadn't really been found or documented until this
year). For one, the exact shift is randomized every time (there's an
fRandom() call to cycle the colors). For two, it goes away after the
player saves and reloads the level. And for three, it doesn't animate
like it does in finalmode (this is the biggest reason IMO).
Nevertheless, I've decided to keep support for this in custom levels, in
case someone in the future does want to use it and is okay with the
limitations.
There's a bit of inconsistency with how long each color lasts for during
final stretch. Initially, each color lasts for 40 frames, but when you
enter either of the minitowers, the color switches to lasting for 15
frames only. This is because a final_colorframe of 1 makes it go for 40
frames, but a final_colorframe of 2 makes it go for 15 frames - and
final_colorframe gets set to 2 whenever you enter a minitower.
This seems like an oversight because (1) final_colorframe doesn't affect
anything inside the minitower, (2) final_colorframe doesn't get saved to
the save file and always gets set to 1 if your save file has
finalstretch set to true, so saving and reloading will set the colors
back to 40 frames each, and (3) final_colorframe doesn't get set back to
1 when leaving the minitowers.
When you enter the Super Gravitron, you have to wait until the Super
Gravitron actually starts before being able to press Enter to return to
the Secret Lab. This is annoying if you just want to get back to the
Secret Lab. So, I've made it so the press-Enter-to-return functionality
is enabled from the moment that the Super Gravitron starts.
It turns out, despite the game attempting to prevent you from using
invincibility or slowdown in the Super Gravitron by simply preventing
you from entering the Secret Lab from the menu, it's still possible to
enter the Super Gravitron with it anyways. Just have invincibility or
slowdown (or both!) enabled, enter the game normally, and talk to
Victoria when you have 20 trinkets, to start the epilogue cutscene.
Yeah, that's a pretty big gaping hole right there...
It's also possible to do a trick that speedrunners use called
telejumping to the Secret Lab to bypass the invincibility/slowdown
check, too.
So rather than single-case patch both of these, I'm going to fix it as
generally as possible, by moving the invincibility/slowdown check to the
gamestate that starts the Super Gravitron, gamestate 9. If you have
invincibility/slowdown enabled, you immediately get sent back to the
Secret Lab. However, this check is ignored in custom levels, because
custom levels may want to use the Super Gravitron and let players have
invincibility/slowdown while doing so (and there are in fact custom
levels out in the wild that use the Super Gravitron; it was like one of
the first things done when people discovered internal scripting).
No message pops up when the game sends you back to the Secret Lab, but
no message popped up when the Secret Lab menu option was disabled
previously in the first place, so I haven't made anything WORSE, per se.
A nice effect of this is that you can have invincibility/slowdown
enabled and still be able to go to the Secret Lab from the menu. This is
useful if you just want to check your trophies and leave, without having
to go out of your way to disable invincibility/slowdown just to go
inside.
This factors out the slowdown and invincibility conditionals to a
function. This means less copy-pasted code, and it also conveys intent
(that we don't want to allow competitive options if we have either of
these cheats enabled).
This function isn't implemented in the header because then we would have
to include Map.h for map.invincibility, and transitive includes are
evil. Although, map.invincibility ought to be on Game instead (it was
only mapclass due to 2.2-and-previous argument passing), but that's a
bunch of variable reshuffling that can be done later.
They are now factored out to an inline function named incompetitive().
This is so their usage can be changed without having to change each
individual one in every place. This also clarifies the intent of using
these conditionals (they are for when we're in a "competitive" mode).
Tower backgrounds have a bypos and bscroll. bypos is just the y-position
of the background, and bscroll is the amount of pixels to scroll the
background by on each frame, which is used to scroll it (if it's not
being redrawn) and for linear interpolation.
For the tower background (and not the title background), bypos is
map.ypos / 2, and bscroll is (map.ypos - map.oldypos) / 2. However,
usually bscroll gets assigned at the same time bypos is incremented or
decremented, so you never see that calculation explicitly - except in
the previous commit, where I worked out the calculation because the
change in y-position isn't a known constant.
Having to do all these calculations every time introduces the
possibility of errors where you forget to do it, or you do it wrongly.
But that's not even the worst; you could cause a linear interpolation
glitch if you decide to overwrite bscroll without taking into account
map.oldypos and map.ypos.
So that's why I'm adding a function that automatically updates the tower
background, using the values of map.oldypos and map.ypos, that is used
every time map.ypos is assigned. That way, we have to write less code,
you can be sure that there's no place where we forget to do the
calculations (or at least it will be glaringly obvious) or we do it
wrongly, and it plays nicely with linear interpolation. This also
replaces every instance where the manual calculations are done with the
new function.
If you have invincibility enabled and push the camera, the background
would smear. This is because the game doesn't calculate the proper
bscroll and bypos of the tower background, and also doesn't end up
redrawing it.
We do both these things now, so this is fixed.
These places didn't assign map.oldypos when they assigned map.ypos. This
could have only resulted in visual glitches, but it's good to be
consistent and proactively fix these.
This fixes issues where they would be silent for 1 frame due to frame
ordering, resulting in a weird-sounding beginning of these tracks due to
a lack of attack (in the musical sense).
This is similar to the issue where tracks fading in would suddenly be
loud for 1 frame, again due to frame ordering.
This fixes issues with music playing, only for it to fade out
afterwards. This happened if tracks 0 or 7 were played after fading out,
because playing other tracks reset the fade booleans (by calling a
fade-in), but not tracks 0 or 7.
The previous fade system used only one variable, the amount of volume to
fade per frame. However, this variable was an integer, meaning any
decimal portion would be truncated, and would lead to a longer fade
duration than intended.
The fade per volume is calculated by doing MIX_MAX_VOLUME / (fade_ms /
game.get_timestep()). MIX_MAX_VOLUME is 128, and game.get_timestep() is
usually 34, so a 3000 millisecond fade would be calculated as 128 /
(3000 / 34). 3000 / 34 is 88.235..., but that gets truncated to 88, and
then 128 / 88 becomes 1.454545..., which then gets truncated to 1. This
essentially means 1 is added to or subtracted from the volume every
frame, and given that the max volume is 128, this means that the fade
lasts for 128 frames. Now, instead of the fade duration lasting 3
seconds, the fade now lasts for 128 frames, which is 128 * 34 / 1000 =
4.352 seconds long.
This could be fixed using floats, but when you introduce floats, you now
have 1.9999998 problems. For instance, I'm concerned about
floating-point determinism issues.
What I've done instead is switch the system to use four different
variables instead: the start volume, the end volume, the total duration,
and the duration completed so far (called the "step"). For every frame,
the game interpolates which value should be used based on the step, the
total duration, and the start and end volumes, and then adds the
timestep to the step. This way, fades will be correctly timed, and we
don't have potential determinism issues.
Doing this also fixes inaccuracies with the game timestep changing
during the fade, since the timestep is only used in the calculation
once at the beginning in the previous system.
To exclude gravitron squares, the game excluded all entities whose
`size` was 12 or higher. The `size` of the player when they transform
into VVVVVV-Man is 13.
We have already inadvertently fixed VVVVVV-Man not warping vertically in
2.2. This was done with the previous room transition/warping code
refactors; the gravitron square conditionals were simply excluded from
the vertical warp code, because there's no situation where there would
ever be a gravitron square outside the screen vertically.
As with making rescuable crewmates warpable, I have yet to ever see
people use VVVVVV-Man in a custom level. It's not like they would want
to use it anyway; VVVVVV-Man is really, really buggy. And it's probably
better to make it less buggy, starting with this commit.
That being said, VVVVVV-Man's collision when warping horizontally is
really janky, so I still wouldn't use it.
The game excluded every entity whose `type` was 50 or higher. The `type`
of rescuable crewmates is 55.
Could some levels be broken by this behavior? Unlikely; without warping,
the crewmates would end up falling out of the room and would become
unrescuable. So this is more likely to fix than to break.
But more importantly, *no one knows that rescuable crewmates don't
warp*. If anyone would know, it would be me, because I've been in the
custom levels community for over 7 years - and yet, during that time, I
have not seen anyone run into this corner case. If they did, I would
remember! This implies that people simply have never thought about
putting rescuable crewmates in places where they would warp - or they
have, ran into this issue, and worked around it.
With those two reasons, I'm comfortable fixing this inconsistency.
This saves one indentation level. I also fixed the comments a bit
(multiline instead of single-line, "gravitron squares" instead of "SWN
enemies", also commented the player exclusion from horizontal wrapping
in vertically-wrapping rooms).
This fixes a bug where using the fullscreen toggle keybind (Alt+Enter,
Alt+F, or F11) wouldn't update the color of the "resize to nearest" menu
option. The color doesn't functionally change anything - the option
still won't work, and will still have the message telling you that you
need to be in windowed mode when you move your menu selection to it -
but it's an easy inconsistency to fix; just move the menu recreation in
to Screen::toggleFullScreen() itself.
The game dereferences graphics.screenbuffer without checking it first...
it's unlikely to happen, but the least we can to do be safe is to add a
check and assert here.
If there were two scripts with the same name, removing one of them would
only remove the other script from the script name list, and not also
remove the contents of said script - leading to a desync in state, which
is probably bad.
Fixing this isn't as simple as removing the break statement - I either
also have to decrement the loop variable when removing the script, or
iterate backwards. I chose to iterate backwards here because it
relocates less memory than iterating forwards.
No need to use it when good ol' loops work just fine.
Iterating backwards is correct here, in case there happen to be more
than one of the item in the vectors, and also to minimize the amount of
memory that needs to be relocated.
This is a simple change - we draw minimap.png, instead of the generated
custom map, if it is a per-level mounted custom asset.
Custom levels have already been able to utilize minimap.png, but it was
limited - they could do gamemode(teleporter) in a script, and that would
show their customized minimap.png, but it's not like the player could
look at it during gameplay.
I would have done this earlier if I had figured out how to check if a
specific asset was mounted or not.
Previously, if the game couldn't set the write dir to the base
directory, or couldn't make the base directory, or couldn't calculate
the base directory, it would probably dereference NULL or read from
uninitialized memory or murder your family or something. But now, I've
eliminated the potential Undefined Behavior from the code dealing with
the base path.
Previously, this function had a bug due to failing to account for array
decay. My solution was to just repeat the MAX_PATH again. But in
hindsight I realize that's bad because it hardcodes it, and introduces
the opportunity for an error where we update the size of the original
path but not the size in the function.
So instead, just pass the size through to the function.
I don't want to add too many asserts, because sometimes it's okay if a
file is missing (mmmmmm.vvv). But currently, the game basically expects
all images and sound effects to be present. That might change in the
future, but for now, these asserts are okay.
FILESYSTEM_loadFileToMemory() dereferenced pointers without checking if
they were valid... I don't know of any cases where they could have been
NULL, but better safe than sorry.
So, the codebase was kind of undecided about who is responsible for
initializing the parameters passed to FILESYSTEM_loadFileToMemory() - is
it the caller? Is it FILESYSTEM_loadFileToMemory()? Sometimes callers
would initialize one variable but not the other, and it was always a
toss-up whether or not FILESYSTEM_loadFileToMemory() would end up
initializing everything in the end.
All of this is to say that the game dereferences an uninitialized
pointer if it can't load a sound effect. Which is bad. Now, I could
either fix that single case, or fix every case. Judging by the title of
this commit, you can infer that I decided to fix every case - fixing
every case means not just all cases that currently exist (which, as far
as I know, is only the sound effect one), but all cases that could exist
in the future.
So, FILESYSTEM_loadFileToMemory() is now guaranteed to initialize its
parameters even if the file fails to be loaded. This is better than
passing the responsibility to the caller anyway, because if the caller
initialized it, then that would be wasted work if the file succeeds
anyway because FILESYSTEM_loadFileToMemory() will overwrite it, and if
the file fails to load, well that's when the variables get initialized
anyway.
My next commit will involve using goto to jump to the end of a function
to initialize the variables to NULL, but that results in a compiler
error if we have initializations in the middle of the function. We might
as well put all declarations at the top of each block anyway, to help
the move to C, so I'm doing this now.
Since the length variable in the STDIN block now overshadows the length
variable in the outer block, I've renamed the length variable in the
block to stdin_length.
These casts are sprinkled all throughout the graphics code when creating
and initializing an SDL_Rect on the same line. Unfortunately, most of
these are unnecessary, and at worst are wasteful because they result in
narrowing a 4-byte integer into a 2-byte one when they don't need to
(SDL_Rects are made up of 4-byte integers).
Now, removing them reveals why they were placed there in the first place
- a warning is raised (-Wnarrowing) that implicit narrowing conversions
are prohibited in initializer lists in C++11. (Notably, if the
conversion wasn't narrowing, or implicit, or done in an initializer
list, it would be fine. This is a really specific prohibition that
doesn't apply if any of its sub-cases are true.)
We don't use C++11, but this warning can be easily vanquished by a
simple explicit cast to int (similar to the error of implicitly
converting void* to any other pointer in C++, which works just fine in
C), and we only need to do it when the warning is raised (not every
single time we make an SDL_Rect), so there we go.
This fixes a bug where after loading in to the level editor, pressing
Esc and then switching your option to something other than the first
option, then pressing Esc again to close the menu, then pressing Esc
once more would not keep your menu option.
This is because the code that checks if Menu::ed_settings is already in
the stack doesn't account for if ed_settings is the current menu - the
current menu doesn't get put in to the stack.
In hindsight, maybe I could have designed the new menu system better so
the current menu IS on the stack, and/or should have used a
statically-allocated linked list for each menu name for the stack frames
(instead of an std::vector) and asserted if a menu that already existed
in the stack was created instead... that'll have to be done later,
though.
Pressing Esc to cancel the confirm quit menu didn't play the squeak, in
contrast to pressing ACTION to cancel it, so now it does; pressing Esc
to close the pause menu or pressing ACTION will also now play the
Viridian squeak too.
vx/vy mean x-velocity and y-velocity... except here, where it seems like
they're used as extra parameters that do different things depending on
the entity. But it seems like at one point they were actually meant to
be the speed of the entity (this is the case for the unused decorative
particle entities), and then just never got renamed when they weren't.
The custom levels community named these two parameters meta1 and meta2
in the reference list of entities for the createentity() script command,
so that's what I'm naming them here. This will avoid confusion (I know
that some people reading this function have genuinely mistaken the vx/vy
for actually meaning x-velocity and y-velocity, simply because they were
named that way).
I have spelled out each overloaded version instead, and only the
overloads that are actually used - which just happens to be everything
except the 8-argument one. I don't want to deal with callers right now
(there are too many of them), so I'm not going to change the names that
the callers use, nor do I want to change the amount of arguments any
existing callers use right now - but we will have to deal with them in
one way or another when we move to C.
The script command createentity() is always an int. But not only that,
every time createentity() is used, its arguments are always treated like
ints. Always. I knew that vx/vy were floats because of the int casts in
the function, but I didn't even realize that xp/yp were floats, too,
until I checked just now! That's how much they're treated like ints.
All int casts in createentity() have also been removed, due to being
unnecessary (either because of us suppressing MSVC implicit conversion
warnings, or because there are now no longer any conversions happening).
This boolean is assigned, and it is checked... but it's never assigned
to true, thus making it useless. I also checked 2.2 source and the same
thing happens there; to prevent any confusion, I'm removing this.
So... I did see that map.ypos was a float when I added over-30-FPS mode,
because map.oldypos wasn't there before... I'm guessing that I kind of
just ignored it at the time. But, c'mon, map.ypos and map.oldypos are
always treated as ints, so there's literally no reason for them to be
actually floats in reality. I didn't even know they were anything other
than ints until I checked Map.h.
This is quite simple - whenever the user uses their keyboard or
controller, we hide the mouse cursor. Whenever they move the mouse, we
show it again. This makes it so the cursor gets out of the way when they
play the game, but reappears when they need it.
There is also a timeout, to prevent strobing if the user decides to use
the keyboard/controller and mouse at the same time. There is no timeout
from hiding the mouse cursor, but there is a timeout from showing the
mouse cursor - this because it's okay if the mouse lingers for a few
frames when you start using the keyboard, but really annoying if the
mouse doesn't instantly appear when you move it.
The config option has been removed. I'm going to implement something
that automatically shows and hides the mouse cursor whenever
appropriate, which is better than a config option.
These are two C++ features that we don't need, don't use, and will never
use in the future. Apparently the best way of doing this in CMake is to
fiddle with the CXX_FLAGS using regex.
Now this is one less flag I need to supply myself when I invoke CMake...
This variable is not defined anywhere and never has been since the
source code release (which is when this CMake file was first created).
To make things clearer, I'm cleaning this variable up.
A function like add_definitions() adds definitions to ALL targets, not
just VVVVVV. This kind of namespace pollution is messy, and could result
in bugs if you pollute with the right kind of pollutant.
So instead of using add_definitions(), use target_compile_definitions().
And instead of using include_directories(), use
target_include_directories().
All the C third-party dependencies are C90, and all the C files we have
are also C90 (well, almost, but that's easily sorted). So we have
basically no reason to not go with C90 here.
The only wrinkle is, turning C extensions off for physfs-static results
in linker errors because PhysFS implicitly uses alloca() without
including it properly (on Linux). I am not the only one who has ran into
this - see https://icculus.org/pipermail/physfs/2020-April/001293.html -
and it's a bug with PhysFS. The workaround I've gone with is to enable C
extensions. (There might also be some funkiness with PhysFS's use of the
`inline` keyword, so enabling extensions will paper over that as well.)
So there were actually only two instances of C99-style end-of-line
comments in C files - and technically one of them was just a C file
including MakeAndPlay.h.
It seems like CMake 3.1.3 introduced the C/C++ standard properties,
while the minimum version of this CMake file is 2.8.12. So we do what
FAudio does, which is print a warning if the CMake version is too old
and otherwise use it if we have the feature.
They're the same thing, but using option() better conveys intent.
However this can't be done for anything that isn't a bool, which the
CUSTOM_LEVEL_SUPPORT option is not (it's a tri-state string).
These were introduced in 098fb77611 - did
Leo not know that they were already there at the top of the file? This
does the same thing, except it only sets it for VVVVVV instead of
everything (so this wouldn't set it for the third-party dependencies).
If a track was restarted after it faded out, then it wouldn't play. This
is because currentsong wasn't set to -1 after fading out, and that is
because the fade out calls pause() instead of haltdasmusik() when it
finishes.
Unlike f196fcd896, this fixes the time
trial music while keeping it to the same behavior as 2.2, and fixes
every single possible case that this music bug could have happened.
This reverts only a part of f196fcd896 -
as the original commit author did not do their changes atomically, they
also squashed in a de-duplication within the same commit. So I'm only
reverting the part of the commit that wasn't the de-duplication, which
is simply the changes to the music.fadeout() calls.
This is being (partially) reverted for several reasons:
1. It's not the correct behavior. What this does instead is persist the
track through after you restart the time trial, instead of fading it
out, then restarting it again. This is in contrast to behavior in
2.2, and I see no reason to not keep the same behavior.
2. It's a single-case patch. The time trials are not the only time in
the game a music track could fade out and then be restarted with the
same track - custom levels could do the same thing too. Instead of
fixing only one case, we should strive to fix EVERY case.
The original commit author (trelbutate) also didn't write anything in
the commit description of f196fcd896. What
you should write in the commit description is things like rationale,
analysis, and other good information that would be useful to anyone
looking at your commit to understand why you did what you did. Having no
commit description leaves readers in the dark as to why you did what you
did.
Thus, I don't know why trelbutate went with this solution, or if they
knew that it was only a single-case patching, or if they knew that it
wasn't 2.2 behavior.
By not writing the commit description, they miss a chance for
reflection; speaking from personal experience, I myself have gone back
and improved my commits countless times because I wrote commit
descriptions for every single one of them, and sometimes whenever I
write them, I think to myself "hang on a minute, that doesn't sound
quite right" and end up finding improvements.
If trelbutate wrote a commit description, they might have realized that
it wasn't 2.2 behavior, and gone back and fixed up their commit to be
correct. As it stands, though, they didn't have to think about it in the
first place because they never bothered to write a commit description.
edteleportent is a global variable that gets assigned whenever the
player collides with a warp token, and gets read from later down the
line in gamelogic(). While I don't know of any way to cause anything bad
with this (and I did try), storing a temporary indexing variable like
this is only bound to be a liability in the future - so we might as well
prevent badness now by adding a bounds check here.
This fixes a bug where quitting to the menu from command-line
playtesting with -playassets specified would always use those assets
when loading back in to any custom level. This also fixes loading in to
a custom level quicksave always using the command-line playtesting
arguments instead of using the actual quicksave.
In a vertically-warping room, the 'height' of the room becomes 232
pixels, regardless of if you have a room name or not. So the remaining 8
rows of pixels at the bottom of the screen corresponds with the first 8
rows of pixels at the top of the screen, and entities in the bottom 8
rows of pixels get teleported to the top of the screen.
The screen wrapping drawing code doesn't draw entities in the top 8 rows
of pixels at the bottom, leading to a discontinuous effect where it
looks like vertically-warping entities don't neatly change from the
bottom to the top or vice versa - this is especially noticeable with
enemies. To fix this, just increase the threshold for drawing top
entities at the bottom of the screen by 8 pixels.
When an entity vertically warps, it teleports upwards or downwards by
232 pixels. However, the graphics code draws them with an offset of 230
pixels. This is off by 2 pixels, but it's enough to make a
downwards-moving enemy look like it suddenly collides with the bottom of
the screen (in a room without a room name) before it warps, especially
if you go frame-by-frame.
It seems like for whatever reason that the frames portion of save files
is never read from, and always zeroed. Well, technically they get parsed
but the result is immediately discarded afterwards.
I see no reason to do this, so I'm removing these zeroes.
This fixes being able to make music fully fade in (or out) by unfocusing
the game, or making the fade bars fully fade in (or out) by unfocusing
the game, or racking up the timer while the game is unfocused.
In 2.2 and previous, the game would call resetgameclock() every frame
for the last 30 frames of the time trial countdown in order to make sure
it gets reset. This was in a render function, and didn't get brought out
in 2.3, so 2.3 resets the game clock *while rendering*, which is kinda
bad and is an oversight on my part for not noticing.
Instead of doing that, just add a conditional to the timer so that it
won't tick during the time trial countdown. This fixes#699 even further
by making it so the time trial par can't even be lost during the
countdown, because the timer won't tick up - so you can never get a sad
squeak to play by pausing the game or unfocus-pausing it during the
countdown.
For some reason, resetgameclock() is only ever used in gamerender(), and
everywhere else just zeroes the clock manually. This is weird to me, so
I've made it so everywhere that zeroes the clock uses the
resetgameclock() function to do so.
Otherwise, if the timer ticked up past the par (via using the unfocus
pause or pause menu), it would result in the sad squeak being played
every frame because the game would constantly be setting
timetrialparlost, then moving to the code block below, assuming that
since timetrialparlost that we haven't lost the par already, and playing
the squeak.
timetrialparlost gets reset in hardreset() and startgamemode() anyways,
so there's no need to be constantly resetting this variable.
Fixes#699.
It turns out this entire chunk of code is simply unneeded (and is
actively harmful) since when we're done with the time trial,
quittomenu() gets called, and that removes the previous stack frame
anyway.
I'm guessing that I added this code, then added quittomenu(), then
didn't consider how this code and quittomenu() would mix. But anyways,
this bug is fixed.
Fixes#714.
This seems to be a comment left by Ethan that he never got around to. So
I did it for him.
What I've done is made it so FileSystemUtils.cpp knows what a binary
blob is, and moved the binary blob loading code directly to
FileSystemUtils.cpp. To do this, I removed the private access modifier
from binaryBlob - I don't think we'll need it, and anyways when we move
to C we can't use it.
Along the way, I also cleaned up the style of the function a bit - the
null termination offset is no longer hardcoded, and the function no
longer mixes code and declarations together in the same block.
I also noticed that when printing all the filenames at the end, a single
invalid header would stop the whole loop instead of just being skipped
over... this seems to be a bug to me, so I've made it so invalid headers
just get skipped over instead of stopping the whole loop.
In FileSystemUtils.h, I used a forward declaration. In hindsight,
incomplete forward declarations should basically always be done in
header files if possible, otherwise this introduces the possibility of
transitive includes - if a file includes this header and it does a full
include, the file is silently able to use the full header, whereas if
it's a forward declaration, then the moment the file tries to use the
full header it fails, and then it's forced to include the full header
for itself. But uh, that's a code cleanup for later.
While fixing all the other music bugs, I discovered that starting
playtesting in the editor wouldn't play the level music.
The problem is that the editor playtesting start code calls
music.fadeout() before calling music.play(). This queues up the track
from the music.play() call. After that, what should happen is that
processmusic() processes the fade, the fade is then finished, and then
after that it sees that the music is halted so it can play the queued
track.
Instead what happens is that the function first attempts to play the
music before the fade is processed and finished, so play() will re-queue
the music again, but the queue gets cleared right after that (this is a
subtle bit of behavior - it means if the game fails to play a queued
track due to it fading, it's not going to re-queue it again and end up
in some sort of infinite loop).
This is a frame ordering issue - the function is tripping over itself
when it shouldn't be. To fix it, just put the queue processing code
after the fade processing code.
This fixes the 2.2-and-below music blocking workaround not working in
2.3.
The issue was that when the music got halted by the script, the fade
volume would still be processing, silently being decremented in the
background. So the script playing the track afterwards would make the
game queue it (as it was called during the fade), but then the music is
halted so the game would attempt to play it, but the fade is STILL
happening so it wouldn't actually play it and would attempt to queue the
track again.
However, that queue gets discarded immediately afterwards because the
music.play() call happened inside the code responsible for playing the
queued music, and that code unconditionally clears the queue variables
immediately after calling play(). So that's good to know - if the game
queues a song, but fails to play it because of a fade, it's not going to
immediately re-queue it and potentially get stuck in a loop of
infinitely queueing the same song over and over again each frame.
Anyways, the source of the problem is not resetting the fade booleans
when halting music, so I've reset them.
Fixes#701.
The problem here is that even though we start playing the music when the
volume is set to zero, mixer's state doesn't have volume zero, so
whatever it plays next will be the very first quanta of the track but at
the previous volume (in this case, the maximum volume). To fix this,
just update mixer when we update the volume here - it's okay to not
account for user volume because it ends up being zero anyway.
Fixes#710.
This fixes a bug where fading music in but not going through the
music.play() path wouldn't start the fade volume from zero. If this
happened, then the previous volume would persist, and if the previous
volume was the max volume, then that essentially canceled out the
fade-in and prevented it from happening at all. But now all paths to
fadeMusicVolumeIn() set the volume to zero first, instead of only the
caller of music.play().
When you pick up a trinket in the wild, the music gets silenced, so it
silently plays in the background until you advance the trinket text.
However, foundtrinket (used when Victoria or Vitellary give you a
trinket) is inconsistent with this, and halts the music instead of
silencing it.
This was probably due to the musicfadein script command not being
implemented, so Terry or Simon had to simply make do and halt the music
instead. But musicfadein is implemented and is being used in the trinket
cutscenes, so this is another inconsistency that I will fix.
When you pick up a trinket in the wild, the music will fade back in
afterwards. However, the special trinket cutscenes (where Victoria or
Vitellary will directly give you a trinket) are inconsistent with this,
and restart the music instead of fading it back in.
Looking at the scripts themselves, it immediately becomes obvious the
reason for this inconsistency - 2.2 and previous didn't implement the
musicfadein command, so it couldn't be used, and Terry or Simon simply
had to make do with simply restarting the music. However, 2.3 implements
musicfadein, so we can simply swap it out and remove the
trinketscriptmusic command.
This is 2.2 behavior, which I forgot to keep. Otherwise, if music has
halted and you try to play the same track, it simply won't work, because
the current song is the same as the song you're trying to play. This is
what happened with the trinket scripts - the game halted music, then
tried to play the same track.
Fixes#712.
It's not really used because CreateDirectory doesn't support setting
chmod values, but it does clarify intent of the argument.

In #52 I fixed VVVVVV not being able to handle filepaths with non-ASCII
characters on Windows. 2f0a0bce4c and
aa5c2d9dc2 reintroduce this problem,
however, by reverting the definition of mkdir to how it was before the
fix and using the non-Unicode version of CreateDirectory. And I can
confirm that VVVVVV indeed doesn't make its folder anymore with a
Windows username of "тест". This commit fixes that issue.
This adds music and volume sliders to the audio options. To use the
sliders, you navigate to the given option, then press ACTION, and your
selection will be transferred to the slider. Pressing left or right will
move the slider accordingly. Then you can press ACTION to confirm the
volume is what you want and deselect it, or you can press Esc to cancel
the volume change, and it will revert to the previous volume; both
actions will write your settings to disk.
Most of this commit is just adding infrastructure to support having
sliders in menus (without copy-pasting code), which is a totally
completely new user interface that has never been used before in this
game. If we're going to be adding something new, I want to make sure
that it at least is done the RIGHT way.
Closes#706.
This adds <musicvolume> and <soundvolume> tags to unlock.vvv and
settings.vvv, so users' volume preferences will be persistent across
game sessions. This does not add the user interface to change them from
in-game; the next commit will do that.
This function is simple - it takes a given buffer and its size, fills it
with a certain character, and null-terminates it. It's meant to be used
with freshly-created buffers, so we don't copy-paste code.
Pressing return in gameplay options would send you back to the pause
menu instead of the general options menu, and pressing return in graphic
options would send you back to the pause menu instead of the general
options menu, too. Additionally, pressing Esc in graphic options would
also send you back to the pause menu instead of the general options
menu.
Like I said before, the menu system is still a bit hardcoded in some
places, and these happened because Terry forgot to update them when he
changed the menus around.
Fixes#711.
The in-game menu code is better than it was in 2.2 but still pretty
hardcoded, so to fix this just change each individual case around. This
bug happened because the "options" button was in the place where "quit
to menu" was previously, but Terry forgot to update it when changing all
the options around.
PhysFS requires a write dir to create a directory, so the first PHYSFS_mkdir
never could have worked. Because of that we need to go back to the old mkdir,
and since we're bringing that back we can reuse it for saves/levels, because we
know it works and we don't have to worry about middlewares ruining anything.
When a text box in the script system (not the gamestate system) is
displayed onscreen and "- Press ACTION to advance text -" is up, the
game sets pausescript to true, so the script system won't blare past the
text box and keep executing. Then it also sets advancetext to true.
Crucially, these two variables are different, so if you have pausescript
true but advancetext false, then what happens?
Well, you get softlocked. There's no way to continue the script.
How is this possible? Well, you can teleport to the (0,0) teleporter
(the teleporter in the very top-left of the map) and regain control
during the teleporter animation. To do that, in 2.2 and below, you have
to press R at the same time you press Enter on the teleporter, or in 2.3
you can simply press R during the cutscene. Then once you teleport to
the room, it's really precise and a bit difficult (especially if
Viridian is invisible), but you can quickly walk over to the terminal in
that room and press Enter on it.
Then what will happen is the terminal script will run, but the
teleporter gamestate sequence will finish and turn advancetext off in
the middle of it. And then you're softlocked.
To fix this, just add a check so if we're in gamestate 0 and there's a
script running, but we have pausescript on and advancetext off, just
turn pausescript off so the game automatically advances the script.
This softlock was reported by Tzann on the VVVVVV speedrunning Discord.
If you manage to get softlocked by being stuck in completestop, the next
thing you'll notice is that quitting to the menu or loading back in will
not reset this.
So you can actually softlock yourself in 2.3 by doing the trinket
cutscene, then quitting to the menu (because 2.3 lets you open the pause
menu during completestop). This is a bug, and should be fixed.
You can skip the "You have found a shiny trinket!" cutscene. The
conditions are that this can only be done in the main game, in the main
dimension (no Polar Dimension), the checkpoint that you last touched
must not be in the same room as the trinket, and you have to have
skipped the Comms Relay cutscene. To do the skip, you press R on the
exact frame (or previous frame, if input delay is enabled) that Viridian
touches the trinket. Then, the gamestate will be immediately set to 0
(because of the gotoroom) and the cutscene will be skipped.
Speedrunners of the main game, well, run the main game already, the
only trinket in the Polar Dimension is not one you want to do a death
warp at, and they have a habit of automatically skipping over the Comms
Relay cutscene because they press R at the beginning of the run when
Viridian teleports to Welcome Aboard, to warp back to the Ship and so
they can leave rescuing Violet for later.
So someone reported softlocking themselves by doing the trinket text
skip in 2.3. The softlock is because they're stuck in a state where
completestop is true but can't advance to a state that turns it off. How
does this happen? It's because they pressed R too late and interrupted
the gamestate sequence. In 2.2 and previous, if you're in the gamestate
sequence then you can't press R at all, but 2.3 removes this restriction
(on account of aiming to prevent softlocks). So only on the very first
frame can you death warp and interrupt the gamestate sequence before it
happens at all.
Anyways to fix this, just turn completestop off automatically if we're
in gamestate 0 and there's no script running.
This softlock was reported by Euni on the VVVVVV speedrunning Discord.
So some people reported the levels list crashing when they loaded it.
But this wasn't reproducible every time. They didn't provide any
debugging information, so I had to use my backup plan: doing a full
audit of the code path taken for loading the levels list.
And then I found this. It turns out this was because I used a
LOAD_ARRAY_RENAME() macro on an std::vector. You can't do that because
you need to use push_back() to resize a vector, so the macro will end up
indexing into nothing, causing a segfault. However, this code path would
only be taken if you have an old levelstats.vvv, from 2.2 and previous -
which explains why it wasn't 100% reproducible. But now that I know you
need an old levelstats.vvv, this bug happens 100% of the time.
Anyways, to fix this, just ditch the macro and expand it manually, while
replacing the indexing with a proper usage of push_back().
