In #553, when Dav999 added error messages to settings menus if the game
was unable to successfully save the changed settings, he seemed to have
forgotten the PPPPPP/MMMMMM toggle option.
However, I can fully blame him for only that miss. The Flip Mode options
were using game.savemystats (which was removed in #591), so if he
searched for all instances of game.savestats()
(game.savestatsandsettings() was only added in #557), he would've missed
the game.savemystats.
Later, when I did #591, I didn't realize that I should've replaced the
ones in the Flip Mode options with game.savestatsandsettings_menu(), so
part of the blame does fall on me.
Anyways, this is fixed now.
If there was absolutely no music playing, and you went to the in-game
options to switch between MMMMMM and PPPPPP, the behavior would be a bit
glitchy.
If you started with PPPPPP, switching once to MMMMMM wouldn't play
anything, but then switching back to PPPPPP would play MMMMMM track 15.
Then switching back to MMMMMM wouldn't do anything, but then switching
back to PPPPPP again would play PPPPPP track 15 - and from there, the
behavior is stable.
If you started with MMMMMM, switching once to PPPPPP would play MMMMMM
track 15. Then switching back to MMMMMM wouldn't do anything, but then
switching back to PPPPPP would play PPPPPP track 15 - and as above, the
behavior is stable after that.
Anyways, the point is, -1 shouldn't be passed to musicclass::play()
unless you want glitchy things. And I'm not patching -1 out of
musicclass::play() itself, because passing negative numbers results in a
useful glitch (that's existed since 2.2) where you can play MMMMMM
tracks while having PPPPPP selected, effectively doubling the amount of
usable music tracks within a custom level; it also seems like the game
does -1 checks elsewhere, so I'm just being consistent with the rest of
the game (although, yes, I am technically single-case patching this).
I ran Include What You Use on the file, and a BUNCH of transitive
includes showed up.
colourTransform is used in the file, so GraphicsUtil.h needs to be
included. libc floor() is used in the file, so math.h needs to be
included (I'm removing this next...). NULL is used, so stddef.h. And
stdlib.h is used because we use rand() directly instead of going through
fRandom(). Speaking of which, we use fRandom(), so Maths.h needs to be
included, too.
So, 2.3 added recoloring one-way tiles to no longer make them be always
yellow. However, custom levels that retexture the one-way tiles might
not want them to be recolored. So, if there are ANY custom assets
mounted, then the one-ways will not be recolored. However, if the XML
has a <onewaycol_override>1</onewaycol_override> tag, then the one-way
will be recolored again anyways.
When I added one-way recoloring, I didn't intend for any custom asset to
disable the recoloring; I only did it because I couldn't find a way to
check if a specific file was customized by the custom level or not.
However, I have figured out how to do so, and so now tiles.png one-way
recolors will only be disabled if there's a custom tiles.png, and
tiles2.png one-way recolors will only be disabled if there's a custom
tiles2.png.
In order to make sure we're not calling PhysFS functions on every single
deltaframe, I've added caching variables, tiles1_mounted and
tiles2_mounted, to Graphics; these get assigned every time
reloadresources() is called.
This function will check if a specific file is a mounted per-level
custom asset, instead of being a variable that's true if ANY file is a
mounted asset.
Now you only have to call one function (and pass it a tile number) to
figure out if you should recolor a one-way tile or not, and you don't
have to copy-paste.
It's only used in FileSystemUtils and never anywhere else, especially
not Graphics. Why is this on Graphics again?
It's now a static variable inside FileSystemUtils. It has also been
renamed to assetDir for consistency with saveDir and levelDir. Also,
it's a C string now, and is no longer an STL string.
There's no need to create an std::string for every single element just
to see if it's a key name.
At least in libstdc++, there's an optimization where std::strings that
are 16 characters or less don't allocate on the heap, and instead use
the internal 16-char buffer directly in the control structure of the
std::string. However, it's not guaranteed that all the element names
we'll get will always be 16 chars or less, and in case the std::string
does end up allocating on the heap, we have no reason for it to allocate
on the heap; so we should just convert these string comparisons to C
strings instead.
This bug is technically NOT a regression - the code responsible for it
has been around since the source release.
However, it hasn't been a problem until Graphic Options and Game Options
were added to the pause screen. Since then, if you opened the pause menu
in Flip Mode, pressing up would move to the menu option below, and
pressing down would move to the menu option above. Notably, left and
right still remain the same.
This is because the map screen input code assumes that the menu options
will be flipped around - however, this has never been the case. What
happens instead is that the menu options get flipped around time when in
Flip Mode - flipping what's already flipped - so it ends up the same
again.
(Incidentally enough, the up/down reversing code is present on the title
screen, and is correct - if you happen to set graphics.flipmode to true
on the title screen, the title screen doesn't negate the flipped menu
options, so pressing up SHOULD be treated like pressing down, and vice
versa. However, in 2.3, it's not really possible to set
graphics.flipmode to true on the title screen without using GDB or
modifying the game. In 2.2 and previous, you can just complete the game
in Flip Mode, and the variable won't be reset; 2.3 cleaned up all exit
paths to the menu to make sure everything got reset.)
This isn't a problem when there's only two options, but since 2.3 adds
two more options to the pause screen, it's pretty noticeable.
Anyway, this is fixed by simply removing the branch of the
graphics.flipmode if-else in mapinput(). The 'else' branch is now the
code that gets executed unconditionally. Don't get confused by the diff;
I decided to unindent in the same commit because it's not that many
lines of code.
This fixes a "root cause" bug (that's existed since 2.2 and below) where
recreated surfaces wouldn't preserve the blend mode of their original
surface.
The surface-level (pun genuinely unintended) bug that this root bug
fixes is the one where there's no background to the room name during the
map menu animation in Flip Mode.
This is because the room name background relies on graphics.backBuffer
being filled with complete black. This is achieved by a call to
ClearSurface() - however, ClearSurface() actually fills it with
transparent black (this is not a regression; in 2.2 and previous, this
was an "inlined" FillRect(backBuffer, 0x00000000)). This would be okay,
and indeed the room name background renders fine in unflipped mode - but
it suddenly breaks in Flip Mode.
Why? Because backBuffer gets fed through FlipSurfaceVerticle(), and
FlipSurfaceVerticle() creates a temporary surface with the same
dimensions and color masks as backBuffer - it, however, does NOT create
it with the same blend mode, and kind of sort of just forgets that the
original was SDL_BLENDMODE_NONE; the new surface is SDL_BLENDMODE_BLEND.
Thus, transparency applies on the new surface, and instead of the room
name being drawn against black, it gets drawn against transparency.
Here I'm using "surface recreation" to mean allocating a new surface
with almost the exact same properties as a given previous. As you can
see, GraphicsUtil likes to recreate surfaces all the time - copying the
masks and flags (unused lol) of an existing surface - and only varies it
by the dimensions of the new surface.
As you can see, this is a lot less wordy and a lot less repetitive than
copy-pasting it a bunch.
In normal mode, the room name is at the bottom of the screen. When you
bring up the map screen, it appears as if the room name is moving up
from the bottom of the screen, and the map screen is "pushing" it up.
The effect is pretty seamless, and when I first played the game (back in
2014), I thought it was pretty cool.
However, in Flip Mode, the room name is at the top of the screen. So one
would expect the menu animation to come from above the screen. Well, no,
it still goes from the bottom of screen; ruining the effect because it
seems like there are two room names on the screen, when there ought to
be only one.
To be fair, I only noticed this while fixing another bug now, but it's
one of those things you can't unsee (I have cursed you with knowledge!);
not to mention that I probably only didn't notice this because I don't
play in Flip Mode that often (and I'd wager almost no one does; Flip
Mode previous to 2.3 seems to have been really untested, like I said
in #165). It feels like a bit of an oversight that the direction of the
animation is the same direction as in unflipped mode. So I'm fixing
this.
If you stood in two activity zones at once, you'll automatically select
the one that got created first. And when you activated it, the activity
zone prompt would switch to fading out the prompt of the OTHER activity
zone, the one you didn't activate.
This wasn't a problem in 2.2 and previous, because the fading animation
was simply bugged and defaulted to being solid black. However, in 2.3,
the fading animation is fixed, so this is possible.
Also, this really only happens in the main game. Since there's only one
type of useful activity zone in custom levels - namely the terminal
activity zone - if two activity zones did happen to overlap, activating
one of them wouldn't result in visibly fading out a different activity
zone (because they both look the same); furthermore custom level makers
are careful to not overlap terminal activity zones, lest this result in
player confusion; furthermore the placed activity zones only cover a
small area, whereas in the main game, crewmates' activity zones are
pretty big.
(Technically, you CAN create main game activity zones in custom levels,
but those are hardcoded to call main game scripts, and basically nobody
uses them.)
So what's the solution? Simply adding game.hascontrol and script.running
checks to the updating of game.activity_last[prompt|r|g|b].
Why not add those checks to the assignment of game.activeactivity, just
above? Because that would introduce a frame ordering issue (that
would NOT be (automatically) fixed by #535) where the eligibility of
pressing Enter on an activity zone now checks if you were standing in an
activity zone LAST frame, and not THIS frame. (I tested this with
libTAS.) Better to fiddle with the rendering code than fiddle with the
actual physics code.
The specific spot I used to test this was standing in Violet's activity
zone and the activity zone of the ship radio terminals (the three
terminals on the ground in her room); the ship radio terminals are
first-placed, so if you're testing this (and you should!), make that the
prompt is of the ship radio activity zone before activation.
This probably should've been moved to RenderFixed a while ago, because
it's unnecessary to run this on every single deltaframe.
The only minor wrinkle here is that this means rendering of activity
zone fades will be delayed for 1 frame, but #535 will fix that.
Since you're now allowed to bring up the map screen during cutscenes,
you've also been able to activate activity zones and teleporter prompts
during cutscenes. This only really affects custom levels; nowhere in the
main game can you overlap with an activity zone while in a cutscene.
To fix this, I've just added a script.running check to Enter keybind
processing.
I was looking through all calls to game.returnmenu(), and I noticed that
the return option in the game pad screen didn't have a
map.nexttowercolour(). I tested it and, yep, returning from there
doesn't update the background color.
So that should be fixed now.
I'm... not sure why this was here? It's absolutely not needed.
I'm guessing maybe at one point during development, there might have
been wanted a special song to be played during the credits, or no song
at all (although the function being niceplay() instead of play() seems
to support the first possibility) - but there's no need for this to be
here.
Now that recreating the same menu keeps currentmenuoption, we can remove
all these superfluous assignments. This means repeating ourselves less;
in case the option numbers change in the future, we won't have to
remember to update these reassignments, too.
When recreating the same menu, there's basically no reason to reset the
currently-selected menu option. (Also, no need to worry about indexing
out of bounds or anything - the number gets checked while iterating over
all menu options; it's never used to actually index anything. At worst
there might be a 1-frame flicker as the bounds code in gameinput() kicks
in, but that shouldn't happen anyways.)
Zip files that have been successfully mounted in editorclass::loadZips()
will now be ignored when the game does its second pass over the levels
directory. Otherwise, this would produce a superfluous error message,
because the game would attempt to parse the zip file as a level file
(when it's not a level file and is in fact a binary file).
This returns if the file given is mounted or not. 2.3 added level zip
support, so whenever the game loads level metadata, it will mount any
zip files in the levels directory; this function can be used to check if
any of those files have been mounted, and ignore them if so.
Otherwise, this would produce a superfluous warning message in the
console. Directories are now ignored and never attempted to be opened;
so now any warning messages printed out are genuine file that something
has genuinely gone wrong with.
Well, there's still a warning message printed if there's a symlink to a
directory; this is rarer, but it's still a false positive.
This function will be used to differentiate files from directories.
Or at least that was the hope. Symlink support was added in 2.3, but it
doesn't seem like PHYSFS_stat() lets you follow the symlink to check if
what it points to is itself a file or directory. And there doesn't seem
to be any function to follow the symlink yourself...
So for now, this function considers symlinks to directories to be files.
PHYSFS_readBytes() returns a PHYSFS_sint64, but we forcefully shove it
into a 32-bit signed integer.
Fixing the type of this doesn't have any immediate consequences, but
it's good for the future in case we want to use the return value for
files bigger than 2 gigabytes; it doesn't harm us in any way, and it's
just better housekeeping.
PHYSFS_fileLength() returns -1 if the file size can't be determined. I'm
going to set it to 0 instead, because it seems like that's more
well-behaved with consumers.
Take lodepng_decode24() or lodepng_decode32(), for example - from a
quick glance at the source, it only takes in a size_t (an unsigned
integer) for the filesize, and one of the first things it does is malloc
with the given filesize. If the -1 turns into SIZE_MAX and LodePNG
attempts to allocate that many bytes... well, I don't know of any
systems that have 18 exabytes of memory. So that seems pretty bad.
The function returns a PHYSFS_sint64, but we forcefully shove it into a
PHYSFS_uint32. This means we throw away all the negative numbers, which
is bad because the function returns -1 if the size of the file can't be
determined; plus, we also throw away 32 bits of information, reducing
our range of supported file sizes from 9 exabytes to 4 gigabytes.
File size support is only as good as the weakeast link, and it looks
like one of the consumers of FILESYSTEM_loadFileToMemory(),
SDL_RWFromConstMem(), only takes in a signed 32-bit integer of size;
however, I would still like to do at least the bare minimum to support
as many file sizes as we can, and changing types around is one of those
bare minimums.
I had misread this line in #629 and thought that it was just clearing
the entire surface, when really it was filling the surface with opaque
black. ClearSurface() would instead make it transparent, which would
mean when it got drawn, it would get drawn against blue, and not black.
Whoops.
These float attributes are assigned to, and then never read again. The
coordinate systems of blocks are a bit of a mess - some use xp/yp, some
use xp/yp and rect.x/rect.y - but I can confidently say that these are
never used, because it compiles fine if I remove the attributes from the
class, plus remove all assignments to it.
Screen.cpp wasn't explicitly including SDL.h, instead relying on
Screen.h to include it.
It was also relying on SDL.h to include stdio.h on Linux, which breaks
because SDL.h doesn't include stdio.h on Windows. So stdio.h is now
explicitly included as well.
stdlib.h is not used in this file.
After reasoning about it for a bit, there's no reason for these checks
to be here. `zip_normal` will either be
/home/infoteddy/.local/share/VVVVVV/levels if the asset directory is a
directory, or levels/levelname.zip if the asset directory is inside the
same zip as the level is. I don't see how they could ever be data.zip.
My guess is because of the VCE bug where it messed up its search path,
and before that bug was fixed, it had to be worked around here by
explicitly blacklisting data.zip here. When the assets mounting stuff
was ported from VCE to vanilla, vanilla didn't have the problem, and so
this data.zip blacklisting stuff was unnecessary.
Either way, I see no reason for this, so I'm going to remove it.
There is no need to use heap-allocated strings here, so I've refactored
them out. I've also cleaned up both of the functions a bit, because the
line spacing of the previous version was completely non-existent, brace
style was same-line instead of next-line, and the variable names were a
bit misleading (in FILESYSTEM_mountassets(), there is a `zippath` AND a
`zip_path`, which are two completely different variables).
Also, FILESYSTEM_mount() now prints an error message and bails if
PHYSFS_getRealDir() returns NULL, whereas it didn't do that before.
The function is literally just an alias for PHYSFS_exists(), which does
not exclusively check for directories. Plus, the function is also used
to check if a non-directory file exists. Why is this function named
"directoryExists"?!
The info message when a .data.zip file is mounted is now differentiated
from the message when an actual directory is mounted (the .data.zip
message specifies ".data.zip").
The error message for an error occurring when loading or mounting a .zip
is now capitalized.
The "Custom asset directory does not exist" now uses puts(), because
there's no need to use printf() here.
I don't know why this is here; it's unused. I don't know why the
compiler doesn't warn about this being unused either - maybe it's
secretly being used? That also means I'm not sure if the compiler is
optimizing this away or not. Anyway, this is getting removed.
The STL here cannot be completely eliminated (because the custom entity
object uses std::string), but at least we can avoid unnecessarily making
std::strings until the very end.
There's not really any reason for this function to use heap-allocated
strings. So I've refactored it to not do that.
I would've used SDL_strrstr(), if it existed. It does not appear to
exist. But that's okay.
PhysFS by default just uses system malloc(), realloc(), and free(); it
provides a way to change them, with a struct named PHYSFS_Allocator and
a function named PHYSFS_setAllocator().
According to PhysFS docs, this function should be called before
PHYSFS_init(), which is why this allocator stuff is handled in
FileSystemUtils.cpp.
Also, I've had to make two "bridge" functions, because PHYSFS_Allocator
wants pointers to functions taking in `PHYSFS_uint64`s, not `size_t`s.
ClearSurface() is less verbose than doing it the old way, and also
conveys intent clearer. Plus, some of these FillRect()s had hardcoded
width and height values, whereas ClearSurface() doesn't - meaning this
change also has better future-proofing, in case the widths and heights
of the surfaces involved change in the future.
When you pass NULL in for the SDL_Rect* parameter to SDL_FillRect(), SDL
will automatically fill the entire surface with that color. There's no
need for us to create the SDL_Rect ourselves.
