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().
While the game does support playing levels with filenames that don't
have the .vvvvvv extension, it doesn't do it well.
Namely, those files can't be loaded or saved into the editor (because a
.vvvvvv always gets tacked on to your input when saving or loading). In
2.3, this gets worse because you can't load a level without a .vvvvvv
extension from command-line playtesting (because a .vvvvvv automatically
gets added) and you can't load per-level custom assets.
The only place where extensionless level files are supported is when
loading level metadata. But this makes it so they no longer work. This
is technically an API break, but it's easily fixed (just add the
.vvvvvv), plus there's nothing to be gained from not having an
extension, plus basically no one ever actually did this in the first
place (as far as I know, I am the only person to have ever done this,
and no one else ever has).
This fixes an issue where you would be able to mount things other than
custom assets in per-level custom asset directories and zips.
To be fair, the effects of this issue were fairly limited - about the
only thing I could do with it was to override a user-made quicksave of a
custom level with one of my own. However, since the quicksave check
happens before assets are mounted, if the user didn't have an existing
quicksave then they wouldn't be able load my quicksave. Furthermore,
mounting things like settings.vvv simply doesn't work because assets
only get mounted when the level gets loaded, but the game only reads
from settings.vvv on startup.
Still, this is an issue, and just because it only has one effect doesn't
mean we should single-case patch that one effect only. So what can we
do?
I was thinking that we should (1) mount custom assets in a dedicated
directory, and then from there (2) mount each specific asset directly -
namely, mount the graphics/ and sounds/ folders, and mount the
vvvvvvmusic.vvv and mmmmmm.vvv files. For (1), assets are now mounted at
a (non-existent) location named .vvv-mnt/assets/. However, (2) doesn't
fully work due to how PhysFS works.
What DOES work is being able to mount the graphics/ and sounds/ folders,
but only if the custom assets directory is a directory. And, you
actually have to use the real directory where those graphics/ and
sounds/ folders are located, and not the mounted directory, because
PHYSFS_mount() only accepts real directories. (In which case why bother
mounting the directory in the first place if we have to use real
directories anyway?) So already this seems like having different
directory and zip mounting paths, which I don't want...
I tried to unify the directory and zip paths and get around the real
directory limitation. So for mounting each individual asset (i.e.
graphics/, sounds/, but especially vvvvvvmusic.vvv and mmmmmm.vvv), I
tried doing PHYSFS_openRead() followed by PHYSFS_mountHandle() with that
PHYSFS_File, but this simply doesn't work, because PHYSFS_mountHandle()
will always create a PHYSFS_Io object, and pass it to a PhysFS internal
helper function named openDirectory() which will only attempt to treat
it as a directory if the PHYSFS_Io* passed is NULL. Since
PHYSFS_mountHandle() always passes a non-NULL PHYSFS_Io*,
openDirectory() will always treat it like a zip file and never as a
directory - in contrast, PHYSFS_mount() will always pass a NULL
PHYSFS_Io* to openDirectory(), so PHYSFS_mount() is the only function
that works for mounting directories.
(And even if this did work, having to keep the file open (because of the
PHYSFS_openRead()) results in the user being unable to touch the file on
Windows until it gets closed, which I also don't want.)
As for zip files, PHYSFS_mount() works just fine on them, but then we
run into the issue of accessing the individual assets inside it. As
covered above, PHYSFS_mount() only accepts real directories, so we can't
use it to access the assets inside, but then if we do the
PHYSFS_openRead() and PHYSFS_mountHandle() approach,
PHYSFS_mountHandle() will treat the assets inside as zip files instead
of just mounting them normally!
So in short, PhysFS only seems to be able to mount directories and zip
files, and not any loose individual files (like vvvvvvmusic.vvv and
mmmmmm.vvv). Furthermore, directories inside directories works, but
directories inside zip files doesn't (only zip files inside zip files
work).
It seems like our asset paths don't really work well with PhysFS's
design. Currently, graphics/, sounds/, vvvvvvmusic.vvv, and mmmmmm.vvv
all live at the root directory of the VVVVVV folder. But what would work
better is if all of those items were organized into a subfolder, for
example, a folder named assets/. So the previous assets mounting system
before this patch would just have mounted assets/ and be done with it,
and there would be no risk of mounting extraneous files that could do
bad things. However, due to our unorganized asset paths, the previous
system has to mount assets at the root of the VVVVVV folder, which
invites the possibility of those extraneous bad files being mounted.
Well, we can't change the asset paths now, that would be a pretty big
API break (maybe it should be a 2.4 thing). So what can we do?
What I've done is, after mounting the assets at .vvv-mnt/assets/, when
the game loads an asset, it checks if there's an override available
inside .vvv-mnt/assets/, and if so, the game will load that asset
instead of the regular one. This is basically reimplementing what PhysFS
SHOULD be able to do for us, but can't. This fixes the issue of being
able to mount a quicksave for a custom level inside its asset directory.
I should also note, the unorganized asset paths issue also means that
for .zip files (which contain the level file), the level file itself is
also technically mounted at .vvv-mnt/assets/. This is harmless (because
when we load a level file, we never load it as an asset) but it's still
a bit ugly. Changing the asset paths now seems more and more like a good
thing to do...
This will clarify which directory, exactly, failed to mount. I know it
gets printed earlier in the mounting process, but it can't hurt to print
it twice, just to be sure. Also this is for consistency.
Default function arguments are the devil, and it's better to be more
explicit about what you're passing into the function. Also because we
might become C-only in the future and to help faciliate that, we should
get rid of C++-isms like default function arguments now.
PHYSFS_getDirSeparator() already gets called and stored in pathSep at
the top of FILESYSTEM_init(). So clearly, two people worked on this
function and forgot that both pieces of code existed at the same time
(or it was one person independently forgetting both).
PhysFS uses platform-independent notation, so we really don't need to
care about getting the correct dir separator here. Especially since we
don't ever do so anywhere else (e.g. load/saveTiXml2Document()), either.
This is to make it clear that this is not a general-purpose mounting
function; it is a helper function for FILESYSTEM_mountAssets()
specifically for treating a directory or file as an assets directory,
and mounting assets from there.
There's no reason to handle mounting .zip files differently than
mounting a directory... we already mount .data.zip files using
FILESYSTEM_mount(), so why go through the trouble of opening a .zip
manually (which means on Windows the .zip can't be touched for the
duration of playing the custom level), making up a place to mount it at,
and then mount that made-up name, instead of just using
FILESYSTEM_mount()?
Whoever cobbled this asset mounting thing together really didn't fully
understand what they were doing.
