Centiseconds won't be saved to any save file or anything. This is just
to make speedrunning a bit more competitive, being able to know the
precise time of a time trial or full game run.
The time trial par time on the result screen always has ".99" after it.
This is basically due to the game comparing the number of seconds to the
par number of seconds using less-than-or-equal-to instead of simply
less-than.
The only reason why gray Warp Zone entities were green originally was
because there is a giant concatenated list of tileset+tilecol
combinations, and by using tileset 3 tilecol 6 you're using the entry
of tileset 4 tilecol 0, which is the green Ship tileset.
So without interfering with the green Ship tileset's entry, I've decided
that the best thing to do is to just add special cases. The enemy color
was easy enough to fix. The platform color was also easy to fix.
However, there exist no existing textures for gray conveyors, so at that
point I decided to just tint the existing green one gray, and then I did
the same for platforms.
This patch is very kludge-y, but at least it fixes a semi-noticeable
visual issue in custom levels that use internal scripts to spawn
entities when loading a room.
Basically, the problem here is that when the game checks for script
boxes and sets newscript, newscript has already been processed for that
frame, and when the game does load a script, script.run() has already
been processed for that frame.
That issue can be fixed, but it turns out that due to my over-30-FPS
game loop changes, there's now ANOTHER visible frame of delay between
room load and entity creation, because the render function gets called
in between the script being loaded at the end of gamelogic() and the
script actually getting run.
So... I have to temporary move script.run() to the end of gamelogic()
(in map.twoframedelayfix()), and make sure it doesn't get run next
frame, because double-evaluations are bad. To do that, I have to
introduce the kludge variable script.dontrunnextframe, which does
exactly as it says.
And with all that work, the two-frame (now three-frame) delay is fixed.
It's annoying for casuals to have to close the game if they manage to
get themselves to turn into VVVVVV-Man, but it's amusing enough to
glitchrunners that they mess about with VVVVVV-Man in the main game,
clipping through walls everywhere (well, they call it Big Viridian, but
still).
Ironically enough, resetting more variables in script.hardreset() makes
the glitchy fadeout system even more glitchy. Resetting map.towermode,
for example, makes it so that if you're in towers when you quit to the
menu, script.hardreset() makes it so that the game thinks you're no
longer inbounds (because it no longer thinks you're in a tower and thus
considers coordinates in the space of 40x30 tiles to be inbounds instead
of 40x700 or 40x100 tiles to be inbounds), calls map.gotoroom(), which
resets the gamestate to 0. So if we're using the old system, it's better
to reset only as much as needed.
And furthermore, we shouldn't be relying on script.hardreset() to
initialize variables for us. That should be done at the class
constructor level. So I've gone ahead and initialized the variables in
class constructors, too.
This was fixed in 2.3 because one of the side effects of this janky
system was being able to accidentally immediately quit to the title if
the screen was black during a cutscene, which is something very likely
to happen to casual players.
Anyway, credits warp uses this gamestate-based system because it
utilizes quitting to the title screen doing gamestate 80. From there,
you increment the gamestate to gamestate 94 to use the Space Station 2
expo script.
This is the second part of what is necessary for credits warp to work.
The speedrunners call this "text storage". You need to get the
advancetext prompt up without a text box in order to be able to
increment the gamestate without bound. In 2.0, script.hardreset() reset
the text boxes, but not the prompt.
This is the first part of what is necessary for credits warp to work.
If the "- Press ACTION to advance text -" prompt is up, and you manage
to keep it up, then you can indefinitely increment the gamestate by
pressing ACTION.
This is first used in credits warp to teleport to the start of Space
Station 2 (by utilizing the Eurogame expo script, triggered by a
gamestate), and then again later by using a teleporter that has a high
gamestate number to increment to the [C[C[C[C[Captain!] cutscene.
Glitchrunner mode is intended to re-enable glitches that existed in
older versions of VVVVVV. These glitches were removed because they could
legitimately affect a casual player's experience. Glitches like various
R-pressing screwery, Space Station 1 skip, telejumping, Gravitron
out-of-bounds, etc. will not be patched.
The tilesheets in question are font.png, tiles.png, tiles2.png,
tiles3.png, entcolours.png, teleporter.png, sprites.png, and
flipsprites.png.
This patch removes the hardcoded dimensions when scanning the
tilesheets, because it's simpler that way. It also de-duplicates it so
it isn't a bunch of copy-paste, by using macros. (I had to use macros
because it was the easiest way to optionally pass in some extra code in
the innermost for-loop.)
Also, if the dimensions of a scanned tilesheet aren't exactly multiples
of the dimensions of the tile unit for that given tilesheet (e.g. if the
dimensions of a scanned tiles.png are not exact multiples of 8), then an
SDL_SimpleMessageBox will show up with the error message, a puts() of
the error message will be called, and the program will exit.
It seems like they were unfinished. This commit makes them properly
work.
When a track is stopped with stopmusic() or musicfadeout(),
resumemusic() will resume from where the track stopped. musicfadein()
does the same but does it with a gradual fade instead of suddenly
playing it at full volume.
I changed several interfaces around for this. First, setting currentsong
to -1 when music is stopped is handled in the hook callback that gets
called by SDL_mixer whenever the music stops. Otherwise, it'd be
problematic if currentsong was set to -1 when the song starts fading out
instead of when the song actually ends.
Also, music.play() has a few optional arguments now, to reduce the
copying-and-pasting of music code.
Lastly, we have to roll our own tracker of music length by using
SDL_GetPerformanceCounter(), because there's no way to get the music
position if a song fades out. (We could implicitly keep the music
position if we abruptly stopped the song using Mix_PauseMusic(), and
resume it using Mix_ResumeMusic(), but ignoring the fact that those two
functions are also used on the unfocus-pause (which, as it turns out, is
basically a non-issue because the unfocus-pause can use some other
functions), there's no equivalent for fading out, i.e. there's no
"fade out and pause when it fully fades out" function in SDL_mixer.) And
then we have to account for the unfocus-pause in our manual tracker.
Other than that, these commands are now fully functional.
This fixes a corner case where using gamestate 82 from the editor would
put you in a softlock because it would return to the editor settings
menu, which only functions in EDITORMODE and results in a softlock in
TITLEMODE.
This is already done for invincibility. It's kind of unnecessary, but
it's just to make sure if for some reason in the future variables like
insecretlab/intimetrial/nodeathmode don't get reset when exiting to the
menu.
To fix this annoying flicker (which, btw, took me WAY too long to do), I
had to introduce yet another kludge variable to signal that the
horizontal/vertical warp background should be re-initialized on the
pause screen.
I think I could technically keep the 'graphics.backgrounddrawn = false;'
in maplogic() and remove the 'graphics.backgrounddrawn = false;' in
Game::returntopausemenu(), but I'm keeping that other one around because
it doesn't hurt and just as a general precaution and safety measure.
This makes it so the tower background doesn't persist and scroll upwards
if you exit the menu in a warp zone horizontal or vertical room.
Ugh, and while we're on the subject of separating the in-game tower
background and the menu tower background, could we PLEASE separate the
horizontal / vertical warp backgrounds from the tower backgrounds, too?!
Another thing that's annoyed me a lot is being unable to simply press
Esc to close the pause menu. You'd have to hover over the "return to
game" or "keep playing" option. This would be even more annoying with
more options on the menu, so allowing to press Esc is a nice
quality-of-life thing.
Otherwise you could keep re-pressing ACTION on the "yes" option and keep
stalling it until it finally faded out, or quickly go back past menu
options or something.
Otherwise the menu background would have this rendering glitch where the
bypos of the in-game tower wouldn't divide easily and have a bunch of
jitters in an otherwise smooth but overall still somewhat smooth
background.
Also set map.tdrawback to true when leaving the menu.
This is to fix the interpolated color of the tower background
persisting, as well as making sure the menu background doesn't persist
when exiting.
This would be fine, under the assumption that you could never reach the
menu from outside the menu. Well, now you can, so now this has to play
the correct song instead of track 6.
This is to pre-emptively prevent piling up stack frames for what I'll be
adding next, which is pressing Esc in the options menu in-game
automatically moving you back to MAPMODE.
Since the exact same tower background is also used on the menu, we need
to save the current state of the background when entering the menu
(before overwriting it), and then put it back when we're done. Maybe we
ought to separate the in-game and menu tower backgrounds...
This also fixes a semi-hilarious bug where you could make Panic Room go
in the other direction by simply going to the options menu in-game.
This is accomplished by adding convenience functions
mapclass::bg_to_kludge() and mapclass::kludge_to_bg().
Well this is a bit annoying. I can call graphics.updatetowerbackground()
just fine, but I have to get at the title color update routine inside
titlelogic(), which is hard-baked in. So I have to pull that code
outside of the function, export it in the header, and then call it when
I transition to TITLEMODE.
So now the options do what they do. However, I still need to fix the
1-frame glitch when switching to TITLEMODE, as well as make returning
from the menu return back to MAPMODE, as well as making this better menu
integrate seamlessly with the existing menus.
This prevents from having to repeat 'if (game.menupage == ...)'
everywhere, which makes for more concise code.
I know you're technically supposed to indent the cases surrounded by
if-guards, but I don't think indenting them here would help anything.
I'd only indent it if the 'if' had an 'else', for example. But if it
surrounds the whole case, then there's no need for indentation.
