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_CreateRGBSurfaceFrom
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".
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.
I manually rebased 774f8c31a7 and didn't
notice this. The C++ way of doing things where you add together strings
(or worse, bit shift them) is convoluted and lets you easily miss
things like this. If this was a printf format string it'd be
"trinket%ss." which would stick out like a sore thumb.
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.
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.
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.
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.
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 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...
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.
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().
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.
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.
Enemy/platform bounds are intended to not be drawn if they cover the
whole screen, since that's what their default bounds are.
However, the code inadvertently made it so if ANY of the bounds touched
a screen edge, the bounds wouldn't be drawn. This is because the
conditionals used "and"s instead of "or"s. The proper way to write the
positive conditional is "x1 is 0 and y1 is 0 and x2 is 320 and y2 is
240", and when you invert that conditional, you need to also invert all
"and"s to be "or"s. This is not the first time that the game developers
failed to properly negate conjunctional statements...
This is to make it so RNG is deterministic when played back with the
same inputs in a libTAS movie even if screen effects or backgrounds are
disabled.
That way, Gravitron RNG is on its own system (seeded in hardreset()),
separate from the constant fRandom() calls that go to visual systems and
don't do anything of actual consequence.
The seed is based off of SDL_GetTicks(), so RTA runners don't get the
same Gravitron RNG every time. This also paves the way for a future
in-built input-based recording system, which now only has to save the
seed for a given recording in order for it to play back
deterministically.
