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.
Similar to Graphics::map_tab(), this ensures that I don't have to
copy-paste printing the map options for every single game.menupage case
I want, and in this case that's a good thing because there'll be 4
game.menupage cases I'll be using.
This basically adds an extra '|| game.inintermission' because it seems
like the original code forgot about that conditional. You can't save in
level replays, so there's no need to say "You will lose any unsaved
progress." in intermission replays.
In my previous PR, I wrongly assumed that I could just replace the `i`
handling code of those options with an `i++;` at the beginning, and thus
I could put all blocks' `i++;` into ARG_INNER(). Well I was wrong,
because the code was written the original way for a reason, namely that
we still need `i` to point to the -playx/y/rx/ry/gc/music argv so we can
re-compare which argument led us into this code block.
Any decent compiler will optimize this so that it's still only two
function calls (or it gets inlined). However, it's still not very
readable, so I've assigned the result to a variable and used that
instead.
Instead of copy-pasting everything and changing a few parts, just have
something that handles that tiny part. This reduces the amount of code
size the custom level CREW page takes up by half.
This will be used to keep some text positions the same when in Flip
Mode, instead of having to copy and paste code.
This function being at the very top of the file kind of violates
locality, but it has to be done because it can't be a macro.
Previously, the code to print all tab names was copied to every single
tab, resulting in 12 more superfluous print statements than needed. This
commit uses graphics.map_tab to de-duplicate all the code.
This function is useful to de-duplicate all the map page names at the
bottom, which are MAP, CREW/SHIP/GRAV, STATS, and SAVE. If selected, it
will surround the text in square brackets and automatically handle the
positioning.
Shamelessly copy-pasted from Dav999's localization branch.
