Using SDL_GetTicks() to seed the Gravitron RNG caused many
reproducibility issues while syncing https://tasvideos.org/7575S . To
fix this, add a frame counter, which is a number that is incremented
every frame and never resets, and use it instead.
If someone needs to switch back to SDL_GetTicks() for old TASes, then
provide the -seed-use-sdl-getticks command-line option for them.
While fixing #885, I noticed that I had a bunch of
`special/stdin.vvvvvv` entries saved in my `levelstats.vvv`. At once I
knew that the dumb `special/stdin` hack that actually checks if the
filename passed is `special/stdin` was to blame.
STDIN playtesting was first merged, I knew in the back of my mind that
it was a bit of a dumb hack, but I didn't know it would cause
consequences like showing up in `levelstats.vvv`. For now, I'll just
have to patch it, but hopefully in the future I'll remove the dumb hack
entirely. Commenting both instances of the dumb hack with instructions
to grep for it should help maintainers out.
This removes the magic numbers previously used for controlling the fade
mode, which are really not readable at all unless you already know what
they mean.
0: FADE_NONE
1: FADE_FULLY_BLACK
2: FADE_START_FADEOUT
3: FADE_FADING_OUT
4: FADE_START_FADEIN
5: FADE_FADING_IN
There is also the macro FADEMODE_IS_FADING, which indicates when the
intention is to only check if the game is fading right now, which wasn't
clearly conveyed previously.
I also took the opportunity to clean up the style of any lines I
touched. This included rewriting if-else chains into case-switches,
turning one-liner if-then statements into proper blocks, fixing up
comments, and even commenting the `fademode == FADE_NONE` on the tower
spike checks (which, it was previously undocumented why that check was
there, but I think I know why it's there).
As for type safety, we already get some by transforming the variable
types into the enum. Assignment is prohibited without a cast. But,
apparently, comparison is perfectly legal and won't even give so much as
a warning. To work around this and make absolutely sure I made all
existing comparisons now use the enum, I temporarily changed it to be an
`enum class`, which is a C++11 feature that makes it so all comparisons
are illegal. Unfortunately, it scopes them in a namespace with the same
name as a class, so I had to temporarily define macros to make sure my
existing code worked. I also had to temporarily up the standard in
CMakeLists.txt to get it to compile. But after all that was done, I
found the rest of the places where a comparison to an integer was used,
and fixed them.
This prevents writing to unlock.vvv or settings.vvv if the game hasn't
made an attempt to load them yet. Otherwise, if the game aborted via
VVV_exit() because of, say, failure to parse a graphics file, it would
overwrite perfectly existing valid save data since it hasn't loaded it
yet.
Fixes#870.
This is mainly to make sure the game is definitely set to fullscreen in
Big Picture and on the Steam Deck, and to also remove windowed options
that wouldn't make sense if you're not on a desktop (toggling
fullscreen, resize to nearest). Those options would also be removed on
console and mobile too.
There's a bit of an annoying bug where if you launch the game in forced
fullscreen mode, but then exit and relaunch in normal mode, your game
will have fullscreen window sizes but it won't be fullscreen. This is
because forced fullscreen mode tries to preserve your non-forced
fullscreen setting, but due to the way window sizes are stored and
queried, it can't preserve the non-forced window size. This is a bit
difficult to work around, so I'm just putting in a FIXME here because we
can fix it later and I'd rather have a slightly buggy forced fullscreen
mode than not have one at all.
Closes#849.
Here's my notes on all the existing functions and what kind of time
formats they output:
- Game::giventimestring(int hrs, int min, int sec)
H:MM:SS
MM:SS
- Game::timestring()
// uses game.hours/minutes/seconds
H:MM:SS
MM:SS
- Game::partimestring()
// uses game.timetrialpar (seconds)
MM:SS
- Game::resulttimestring()
// uses game.timetrialresulttime (sec) + timetrialresultframes (1/30s)
MM:SS.CC
- Game::timetstring(int t)
// t = seconds
MM:SS
- Game::timestringcenti(char* buffer, const size_t buffer_size)
// uses game.hours/minutes/seconds/frames
H:MM:SS.CC
MM:SS.CC
- UtilityClass::timestring(int t)
// t = frames, 30 frames = 1 second
S:CC
M:SS:CC
This is kind of a mess, and there's a lot of functions that do the same
thing except using different variables. For localization, I also want
translators to be able to localize all these time formats - many
languages use the decimal comma instead of the decimal point (12:34,56)
maybe some languages really prefer something like 1時02分11秒44瞬...
Which I don't know to be correct, but it's good to be prepared for it
and not restrict translators arbitrarily to only changing ":" and "."
when we can start making the system better in the first place.
I added a new function, UtilityClass::format_time. This is the place
where all time formats come together, given the number of seconds and
optionally frames. I have simplified the above-mentioned functions
somewhat, but I haven't given them a complete refactor or renaming -
I mainly made sure that they all use the same backend so I can make the
formats consistent and properly localizable.
(And before we start shoving more temporary char buffers everywhere
just to get rid of the std::string's, maybe we need to think of a
globally used working buffer of size SCREEN_WIDTH_CHARS+1, as a
register of sorts, for when any line of text needs to be made or
processed, then printed, and then goes unused. Maybe help.textrow,
or something like that.)
As for this commit, the available time formats are now more consistent
and changed a little in some places. Leading zeroes for the first unit
are now no longer included, time trial results and the Super Gravitron
can now display hours when they went to 60 minutes before, and we now
always use .CC instead of :CC. These are the formats:
- H:MM:SS
- H:MM:SS.CC
- M:SS
- M:SS.CC
- S.CC (only used when always_minutes=false, for the Gravitrons)
Here's what changes to the current functions:
- Game::partimestring() is removed - it was used in two places, and
could be replaced by game.timetstring(game.timetrialpar)
- Game::giventimestring(h,m,s) and Game::timestring() are now wrappers
for the other functions
- The four remaining functions (Game::resulttimestring(),
Game::timetstring(t), Game::timestringcenti(buffer, buffer_size)
and UtilityClass::timestring(t)) are now wrappers for the "central
function", UtilityClass::format_time.
- UtilityClass::twodigits(int t) is now unused so it's also removed.
- I also added int UtilityClass::hms_to_seconds(int h, int m, int s)
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.
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.
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.
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.)
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.
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.
* 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.
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.
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.
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).
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.
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.
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.
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 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.
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 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.
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.
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().
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.
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).
