This de-duplicates the code, simplifying the codebase and reducing the
number of code paths that needs to be maintained. It also adds
robustness checks to LoadIcon that weren't there before (checking that
loading the file succeeded and that decoding the file also succeeded).
Now, you might think that loading the image with alpha will change
things in some way. But actually, I tested it, and I'm pretty sure it
doesn't. Since my window manager, i3, doesn't display icons, I've had to
resort to this hacky multi-liner
( https://unix.stackexchange.com/a/48866 ) to dump the icon to a PAM
file. I don't know what a PAM file is and all my various attempts to
convert it into something readable failed. But what I did instead was
just grab the icon of the game before this commit (on 2.3, just to be
extra sure), and `diff`ed it with the grabbed icon now, and they end up
being the exact same file. So there's literally no difference.
The only other consideration is that LoadImage needs to be exported,
since it's implemented in GraphicsResources.cpp. I just opted to
forward-declare it right before LoadIcon in Screen.cpp, since it's
really the only other time it's used. No need to create a new header
file for it or anything.
This is just to simplify the function. I really don't see any point in
taking away the alpha for some images, other than to disappoint people
who mod the game assets. It just complicates loading the image with no
real gain. To reduce maintenance costs, let's remove this alternate code
path.
Also it's a default argument and I don't like default arguments.
This argument... doesn't do anything.
First off, setting it to true explicitly enables blending on the
resulting surface, which is kind of the exact opposite of the variable
name and is misleading to say the least? And secondly, SDL surfaces have
blending enabled by default anyways, so it still doesn't even do
anything.
It's also a default argument, and I'm not one to shy away from removing
such default arguments.
This includes:
- Removing the constructor in favor of actually being able to see that
there's an actual function called being made initializing the struct
- Removing the use of a reference in Screen::init() in favor of using a
pointer
- Adding the struct qualifier everywhere (it's not much typing),
although technically you could typedef it in C, but I'd rather much
not typedef just to remove a tag qualifier
I know earlier I removed the gameScreen extern in favor of using
screenbuffer, but that was only to be consistent. After further
consideration, I have found that it's actually really stupid.
There's no reason to be accessing it through screenbuffer, and it's
probably an artifact of 2.0-2.2 passing stack-allocated otherwise-global
classes everywhere through function arguments. Also, it leads to stupid
bugs where screenbuffer could potentially be NULL, which has already
resulted in various annoying crashes in the past. Although those could
be fixed by simply initializing screenbuffer at the very top of main(),
but, why not just scrap the whole thing anyway?
So that's what I'm doing.
As a nice side effect, I've removed the transitive include of Screen.h
from Graphics.h. This could've been done already since it only includes
it for the pointer anyway, but it's still good to do it now.
In aa7b63fa5f, I didn't notice that the
result was implicitly being converted to int by the min/max from before.
I instead added it to the existing char, but that resulted in a char
overflow (it's unsigned, so thankfully not undefined behavior).
But of course the entire point of that commit is to make it explicitly
clear when you are converting between types, intentionally or otherwise,
in min/max comparisons. So despite causing a regression (which I have
now fixed), at least it did its job.
It's been long overdue that this variable be named properly. 2.2 added
integer scaling mode (thanks Ethan), 2.3 renamed it to scaling mode. Now
2.4 will properly call it what it is so people won't be confused by it.
The ScreenSettings struct member is renamed from stretch to scalingMode
along with the Screen class member being renamed, as well as the
toggleStretchMode function being renamed to toggleScalingMode as well.
Unfortunately, due to compatibility, we can't change the <stretch> XML
tag.
VVV_min/max are functions that only operate on ints, and SDL_min/max are
macros that operate on any type but double-evaluate everything.
I know I more-or-less said earlier that SDL_min/max were dumb but I've
changed my mind and think it's better to use them, taking care to make
sure you don't double-evaluate, rather than trying to generate your own
litany of functions with either your own hand-rolled generation macros,
C++ templates, C11 generics, or GCC extensions (that last one you'd
technically use in a macro but it doesn't really matter), all of which
have more downsides than just not double-evaluating.
And the upside of not double-evaluating is that you're disencouraged
from having really complicated single-line min/max expressions and
encouraged to precompute the values beforehand anyway so the final
min/max is more readable. And furthermore you'll notice when you
yourself end up doing double-evaluations anyway. I removed a couple
instances of Graphics::len() being double-evaluated in this commit (as
well as cleaned up some other min/max-using code). Although the only
downside to those double-evaluations was unnecessary computation,
rather than checking the wrong result or having multiple side effects,
thankfully, it's still good to minimize double-evaluations where
possible.
The reason why the wall stuck flipping behavior happened in the first
place was because the code went like this:
if (jumppressed)
{
if (onground && gravitycontrol == 0)
{
gravitycontrol = 1;
}
if (onroof && gravitycontrol == 1)
{
gravitycontrol = 0;
}
}
Basically, if you were both on ground and on a roof (i.e. stuck in a
wall), you would flip, but then due to code order and the fact that the
statement is not connected to the previous one, you would immediately
unflip afterwards. But if you were already flipped then the only path
that can be taken is to unflip you, since it's the statement that
appears last.
52fceb3f69 replaces the onground/onroof
conditionals with any_onground/any_onroof, so any player entity would
allow you to flip. But otherwise the code is the same. So is that the
problem?
No; tracing it through with GDB reveals that when you flip,
gravitycontrol is being set to 1, but never being set to 0. And it turns
out that's because any_onroof is not getting set. And that happens
because of another thing that 52fceb3f69
did - which was to set any_onground/any_onroof to true if indeed any
player entity was on ground or on a roof.
Unfortunately, the way Leo did it was to make the two statements
mutually exclusive - an 'if'-'else if' instead of two separate
statements. So a single entity could not mark both any_onground and
any_onroof as true (and the majority of the time, you will be a single
entity).
Thus, the solution is to just drop that 'else'.
Fixes#855.
I noticed when going frame-by-frame in Vertigo that sometimes the
wrapping enemies at the top sometimes just "popped" in frame. This is
because the sprite warp code only draws the warping sprite of sprites at
the bottom of the screen if they're below y=210. However, the warp point
starts at y=232, and warp sprites can be at most 32x32, which is exactly
the case with the Vertigo sprites, which are exactly 32x32. So the warp
code should start warping sprites if they're below y=200 (232 - 32)
instead.
Horizontal warping also has this problem; it warps at x=320 and
starts drawing warp sprites at x=300, even though it should start
drawing at x=288 (320 - 32). I've gone ahead and fixed that as well.
This is just in case the background gets changed by a custom level or
something to be something that would otherwise result in bad contrast.
Also if it needs to go outside the box for some reason. And I just like
the look of the outline.
Whew, look at all those copy-pasted print statements!
Doing this because of the in-game timer feature. The text would
otherwise clash harshly with the timer otherwise. Even with the outline
it still clashes, but at least there's an outline so it's not as harsh.
This adds centiseconds to the in-game timer, as well as the time trial
timer.
This is to aid speedrun moderators in determining when exactly a run was
completed, which they can't easily do if the timer only has a precision
up to a second.
The problem was that it also needed to check that game.swnmode was true,
in addition to game.swngame being 1, to actually check that the Super
Gravitron was being played.
Currently, all game-gamestate variables are just ints. This is not
particularly type-safe, in case the number of enums changes. To verify
that all current uses of the game-gamestate variables actually use the
enums, change them to be typed with the enum instead.
(As an aside, we should probably rename this so that it can't be
confused with Terry's state machine that has several different ways to
exploit to warp you to the credits, but that's something to do later.)
You'll note that getting in to the glitchy state of the game (the state
where you could play the game after it had hardreset() called on it)
required the player to quit to menu with ingame_titlemode set to true.
Well, quitting to menu calls hardreset(). So if hardreset() is called
when quitting, then you can no longer preserve ingame_titlemode that
way. This is a bit overkill, but I'm just taking precautions.
The game will now assert if the main menu is created while
ingame_titlemode is true, or if we attempt to load into a mode while
it's true. And if assertions are disabled then it just stops doing it
anyway.
I don't think there's any way to get a glitched ingame_titlemode again,
ever since I removed save data deletion taking you back to the main
menu. But I've had enough bugs with the fact that we more-or-less use
the same state for main menu options and in-game options, and that
glitched ingame_titlemode bug DID just happen, so I'm taking
precautions.
The next commit will add logic that more-or-less quits the whole block
if ingame_titlemode, and instead of adding another layer of indentation
I will just pull this into its own function so we can use a return
statement.
While I was testing deleting data while you were in-game, I noticed that
deleting data gave you all the "Win with less than X deaths" trophies,
even if you never got any of them before deleting data. Well, it turns
out that if you have the best game death count of 0, then you win every
trophy, and if you have the best game death count of -1 then that means
you haven't completed the game yet.
This reset was added in e3bfc79d4a, so at
least it's not in 2.3, but I only have myself to blame for making this
mistake. Whoops.
Going back to the main menu allowed for glitchiness to occur if you
deleted your save data while in in-game options. This meant you could
then load back in to the game, and then quit to the menu, then open the
options and then jump back in-game, exploring the state of the game
after hardreset() had been called on it. Which is: pretty glitchy.
For example, this meant having your room coordinates be 0,0 (which is
different from 100,100, which is the actual 0,0, thanks for the
100-indexing Terry), which caused some of the room transitions to be
disabled because room transitions were disabled if the
game.door_up/down/left/right variables were -2 or less, and they were
computed based on room coordinates, which meant some of them went
negative if you were 0,0 and not 100,100. At least this was the case
until I removed those variables for, at best, doing nothing, and at
worst, being actively harmful.
Anyways, so deleting your save data now just takes you back to the
previous menu, much like deleting custom level data does. I don't know
why deleting save data put you back on the main menu in the first place.
It's not like the options menu needed to be reloaded or anything. I
checked and this was the behavior in 2.0 as well, so it was probably
added for a dumb reason.
I considered prohibiting data deletion if you were ingame_titlemode, but
as of the moment it seems to be okay (if albeit weird, e.g. returning to
menu while in Secret Lab doesn't place your cursor on the "play"
button), and I can always add such a prohibition later if it was really
causing problems. Can't think of anything bad off of the top of my head,
though.
Btw thanks to Elomavi for discovering that you could do this glitch.
Okay, so, this is the elephant sprite, right?
https://i.imgur.com/dtS70zk.png
This is how it looks in the actual game, when you stitch all the rooms
together:
https://i.imgur.com/aztVnFT.png
Looks kind of messed-up, doesn't it?
Okay, so, in the bottom two rooms (11,9) and (12,9), the elephant is
placed at y-position -152. But in (11,8) and (12,8), it's placed at
y-position 96. This is despite the fact that -152 plus 240 is 88, not
96.
Similarly, in the left two rooms (11,8) and (11,9), the elephant is
placed at x-position 64, but in the right two rooms (12,8) and (12,9),
the elephant is placed at -264. This is despite the fact that 64 minus
320 is -256, not -264.
All of this stems from the calculations in Otherlevel.cpp using offsets
of -248 and -328 instead of -240 and -320.
So there's an 8-pixel offset that causes the elephant to be chopped off
when viewed with all the rooms stitched together. Simple enough to fix.
For the y-position fixes, I decremented the initial 8-pixel multiplier
as well, else the elephant would sink into the floor.
And this is what the elephant looks like now after stitching:

Thanks to Tzann for pointing this out.
These warnings are kinda spammy, and they make sense in principle.
vlog_error takes a format string, so passing it an arbitrary string
(even error messages from libraries) isn't a good idea.
Dvoid from Discord just reported a crash when trying to load a
custom tiles2.png that was encoded weirdly.
The problem is that we don't check the return value from LodePNG, so
LodePNG gives us a null pointer, and then
SDL_CreateRGBSurfaceWithFormatFrom doesn't check this null pointer,
which then propagates until we crash in SDL_ConvertSurfaceFormat (or
rather, one of its sub-functions), and we would probably crash somewhere
else anyway if it continued.
After properly checking LodePNG's return value, along with printing the
error, it turns out that Dvoid's custom tiles2.png had an "invalid CRC".
I don't know what this means but it sounds worrying. `feh` can read the
file correctly but it also reports a "CRC error".
While we can't fix Canonical, we can at least work around them, and help
people on Ubuntu out by linking them to my comment listing the
currently-known workarounds.
SDL_GetTicks64() is a function that got added in SDL 2.0.18, which is
just an SDL_GetTicks() without a value that wraps every ~49 days,
instead wrapping after the sun explodes and kills us all. Oh sorry,
didn't mean to get existential.
For now, put this behind an SDL_VERSION_ATLEAST guard, which will be
removed when SDL 2.0.18 officially releases and we can update to it.
My latest rebase of #624 (refactoring/splitting editor.cpp) accidentally
overwrote #787 and essentially reverted it entirely. So, add it back in.
This is the same as #787 except it uses the new names, uses SDL_INLINE
to inline the function, and uses named constants.
GCC warns on casting `void*` to function pointers. This is because the C
standard makes a clear distinction between pointers to objects (`void*`)
and pointers to functions (function pointers), and does not specify
anything related to being able to cast object pointers to function
pointers.
The warning message is factually wrong, though - it states that it is
forbidden by ISO C, when in fact it is not, and is actually just
unspecified.
We can't get rid of the cast entirely, because we need the explicit cast
(the C standard _does_ mandate you need an explicit cast when converting
between object pointers and function pointers), and at the end of the
day, this is simply how `SDL_LoadFunction()` works (and more
importantly, how `dlsym()` works), so we can't get rid of it, and we
have no reason to anyways since it means we don't have a hard runtime
dependency on Steam (unlike some other games) and casting `void*` to
function pointers always behaves well on every single platform we ship
on that supports Steam.
Unfortunately, this warning seems to be a part of -Wpedantic, and
there's no way to disable this warning specifically without disabling
-Wpedantic. Luckily, I've found a workaround - just cast to `intptr_t`
before casting to the function pointer. Hopefully the compiler doesn't
get smarter in the future and this ends up breaking or anything...
* Add `setactivityposition(x,y)`, add new textbox color `transparent`
This commit adds a new internal command as a part of the visual activity zone changes I've been making.
This one allows the user to reposition the activity zone to anywhere on the screen.
In addition, this commit adds the textbox color `transparent`, which just sets r, g and b to 0.
rgb(0, 0, 0) normally creates the color black, however in VVVVVV textboxes, it makes the background
of them invisible, and makes the text the off-white color which the game uses elsewhere.
* add new variables to hardreset
* Fix unwanted text centering; offset position by 16, 4
It makes sense for `setactivityposition(0, 0)` to place the activity zone in the default position,
so the x has been offset by 16, and the y has been offset by 4.
Text was being automatically centered, meaning any activity zone which wasn't centered had misplaced text.
This has been fixed by calculating the center manually, and offsetting it by the passed value.
In previous versions, the game mistakenly checked the wrong color
channel of sprites, checking the red channel instead of the alpha
channel. I abuse this in some of my levels. Then I broke it when
refactoring masks so the game now no longer checks the red channel but
seems to check the blue channel instead. So re-fix this to the previous
bug, and preserve the previous bug with a comment explaining why.
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.
