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.
Just to be helpful if someone has a failing FILESYSTEM_init(), but
doesn't know that's their issue and keeps wondering why VVVVVV just
exits with code 1.
The command-line argument parsing code has a lot of copy-paste. This
copy-paste would get even worse if I added safety checks to make sure
you couldn't index argv out-of-bounds by having an argument like
`-renderer` without having anything after it, i.e. you'd be doing the
command `./VVVVVV -renderer`.
Previously, only the playtest arguments (apart from the recently-added
`playassets`) had this safety check, but the message it printed whenever
the safety check failed was always "-playing option requires one
argument" regardless of whatever argument actually failed to be parsed.
So I fixed it so that all arguments actually output the correct
corresponding failed argument instead.
Also, `strcmp(argv[i], <name>) == 0` is really kind of noisy, even if
you understand what it does perfectly well.
So I refactored it with a bunch of macros. ARG() just does the strcmp()
char* comparison, and ARG_INNER() does the safety check and returns 1,
along with printing a message, if the safety check fails.
This is used if you're loading a level file from STDIN. The game needs
to know the actual level assets directory you're referring to, since
when it gets the level from STDIN, it doesn't know the actual filename
of the level.
Fixes#309.
The assets mounting code was put directly in editorclass::load(), but
now it's in a neat little function so it can be called from multiple
places without having to call editorclass::load().
This ensures that endsWith() can be used outside of editor.cpp.
When leo60228 originally wrote endsWith(), it was static, but I asked
him on Discord just now and he more-or-less confirmed that it's fine if
it's not static. If it was static, it would be confined to
UtilityClass.cpp now instead!
Ugh, this is terrible and stupid and I hate myself for it.
Anyway, since the SDL2 VSync hint only applies when the renderer is
created, we have to re-create the renderer whenever VSync is toggled.
However, this also means we need to re-create m_screenTexture as well,
AND call ResizeScreen() after that or else the letterbox/integer modes
won't be applied.
Unfortunately, this means that in main(), gameScreen.init() will create
a renderer only to be destroyed later by graphics.processVsync().
There's not much we can do about this. Fixing this would require putting
graphics.processVsync() before gameScreen.init(). However, in order to
know whether the user has VSync set, we would have to call
game.loadstats() first, but wait, we can't, because game.loadstats()
mutates gameScreen! Gahhhhhh!!!!
@leo60228 suggested to fix that problem (
https://github.com/TerryCavanagh/VVVVVV/pull/220#issuecomment-624217939
) by adding NULL checks to game.loadstats() and then calling it twice,
but then you're trading wastefully creating a renderer only to be
destroyed, for wastefully opening and parsing unlock.vvv twice instead
of once. In either case, you're doing something twice and wasting work.
Otherwise a NO_CUSTOM_LEVELS build would fail. Also I got rid of the
'graphics.flipmode = false;' in the fixed loop because I don't think it
does anything.
This is needed for the next step. I want to put all the loop stuff in
their own functions so the code isn't one huge blob, but to do that I'll
need to make 'time' a global variable, but I can't do that because
actually 'time' is already a function, apparently, and you're only
allowed to shadow variables when already inside a function.
Like actual entities, editor ghost colors were updating every render
frame instead of logic frame. So just like actual entities, I added a
realcol attribute to them that editorrender() uses instead, and added
code to update said realcol attribute in editorlogic(). That way the
colors don't go by too quickly (especially the death color).
Just like all the other fixes, the variable that controls the amount of
ghosts to show was being updated every render frame instead of every
logic frame.
This is because due to the game loop changes in this over-30-FPS patch,
editorrender() can be called and undo graphics.backgrounddrawn being set
to false once again. Solution here is to make it so it keeps being set
to false until game.shouldreturntoeditor is turned off, which has also
been moved to editorlogic().
This is to make sure no lerping occurs in 30-FPS mode, otherwise things
might look weird. A good case that this fixes is how entities look in a
double-gotoroom (they should be completely frozen in 30-FPS mode).
There is now an option in "graphic options" named "toggle fps", which
toggles whether the game visually runs at 1000/34 FPS or over 1000/34
FPS. It is off by default.
I've had to put the entire game loop in yet another set of braces, I'll
indent it next commit.
What happens here is that the entity gets created and then gets
immediately updated on the next frame, but there's no time for their
walkingframe of 0 to be rendered, so it'll look like they have just
started with walkingframe 1. However in the delta-timestep rendering
it'll render with walkingframe 0. So we need to fix their drawframe and
increment it when creating them.
Looks like mapclass::changefinalcol() is called whenever you enter a
room in Outside Dimension VVVVVV.
mapclass::changefinalcol() changes the tile, but it doesn't update their
drawframe. So after that function is called, update their drawframe.
If you update their drawframe while inside that function, then when the
platform actually cycles color it'll cycle backwards quickly sometimes,
which is not ideal.
When I loaded the room where Vitellary is in Space Station 2, I saw this
1-frame glitch happen despite my previous efforts to prevent it. So now
it's fixed.
