This is because destroying the renderer causes use-after-frees since the
renderer destroys all textures when it gets destroyed.
This fixes a Valgrind error where an invalid read occurs because the
font textures get destroyed again after the renderer is destroyed.
This prints the address of every global class to the console, and then
exits.
This is useful for autosplitters, which read memory addresses directly.
Any time a new version of the game is shipped, this makes updating the
autosplitters much easier as people don't have to find the addresses of
the global classes themselves.
I especially focused on graphics.len and the print calls around them,
because graphics.len calls appear a bit less often, might be overlooked
when migrating print calls (thus possibly using different fonts by
accident) and are often used for some kind of right-alignment or
centering which can be changed into PR_RIGHT or PR_CEN with a different
X anyway.
Notably, I also added a new function to generate these kinds of
sliders: ....[]............
Different languages means that the slider for analogue stick
sensitivity needs to be longer to fit possibly long words for
Low/Medium/High, and then different font sizes means that the longer
slider won't fit onscreen in a language that needs a 12-wide font. So
slider_get() can take a "target width", which dynamically changes the
number of characters depending on the width of them in the interface
font.
I kinda forgot that I could force the 8x8 font instead of adapting the
characters in the slider to the font, and other ideas (like using
different characters or a more graphical progress bar) have been
brought up on Discord, so this might all change again sooner or later.
If you for example have your VVVVVV set to English, have the option for
Chinese selected, and then the window loses focus, the English pause
screen would show up in the Chinese font. This is now fixed.
This is still a work in progress, but the existing font system has been
removed and replaced by a new one, in Font.cpp.
Design goals of the new font system include supporting colored button
glyphs, different fonts for different languages, and larger fonts than
8x8 for Chinese, Japanese and Korean, while being able to support their
30000+ characters without hiccups, slowdowns or high memory usage. And
to have more flexibility with fonts in general. Plus, Graphics.cpp was
long enough as-is, so it's good to have a dedicated file for font
storage.
The old font system worked with a std::vector<SDL_Surface*> to store
8x8 surfaces for each character, and a std::map<int,int> to store
mappings between codepoints and vector indexes.
The new system has a per-font collection of pages for every block of
0x1000 (4096) codepoints, that may be allocated as needed. A glyph on
a page contains the index of the glyph in the image (giving its
coordinates), the advance (how much the cursor should advance, so the
width of that glyph) and some flags which would be at least whether the
glyph exists and whether it is colored.
Most of the *new* features aren't implemented yet; it's currently
hardcoded to the regular 8x8 font.png, but it should be functionally
equivalent to the previous behavior. The only thing that doesn't really
work yet is level-specific font.png, but that'll be supported again
soon enough.
This commit also adds fontmeta (xml) support.
Since the fonts folder is mounted at graphics/, there are two main
options for recognizing non-font.png fonts: the font files have to be
prefixed with font (or font_) or some special file extension is
involved to signal what files are fonts. I always had a font.xml in
mind (so font_cn.xml, font_ja.xml, etc) but if there's ever gonna be
a need for further xml files inside the graphics folder, we have a
problem. So I named them .fontmeta instead.
A .fontmeta file looks somewhat like this:
<?xml version="1.0" encoding="UTF-8"?>
<font_metadata>
<width>12</width>
<height>12</height>
<white_teeth>1</white_teeth>
<chars>
<range start="0x20" end="0x7E"/>
<range start="0x80" end="0x80"/>
<range start="0xA0" end="0xDF"/>
<range start="0x250" end="0x2A8"/>
<range start="0x2AD" end="0x2AD"/>
<range start="0x2C7" end="0x2C7"/>
<range start="0x2C9" end="0x2CB"/>
...
</chars>
<special>
<range start="0x00" end="0x1F" advance="6"/>
<range start="0x61" end="0x66" color="1"/>
<range start="0x63" end="0x63" color="0"/>
</special>
</font_metadata>
The <chars> tag can be used to specify characters instead of in a .txt.
The original idea was to just always use the existing .txt system for
specifying the font charset, and only use the XML for the other stuff
that the .txt doesn't cover. However, it's probably better to keep it
simple if possible - having to only have a .png and a .fontmeta seems
simpler than having the data spread out over three files. And a major
advantage: Chinese fonts can have about 30000 characters! It's more
efficient to be able to have a tag saying "now there's 20902 characters
starting at U+4E00" than to include them all in a text file and having
to UTF-8 decode every single one of them.
If a font.txt exists, it takes priority over the <chars> tag, and in
that case, there's no reason to include the <chars> tag in the XML.
But font.txt has to be in the same directory as font.png, otherwise it
is rejected. Same for font.fontmeta. If neither font.txt nor <chars>
exist, then the font is seen as a 2.2-and-below-style ASCII font.
In <special>: advance is the number of pixels the cursor advances after
drawing the character (so the width of the character, without affecting
the grid in the source image), color is whether the character should
have its original colors retained when printed (for button glyphs).
As for <white_teeth>:
The renderer PR has replaced draw-time whitening of sprites/etc
(using BlitSurfaceColoured) by load-time whitening of entire images
(using LoadImage with TEX_WHITE as an argument).
This means we have a problem: fonts have always had their glyphs
whitened at printing time, and since I'm adding support for colored
button glyphs, I changed it so glyphs would sometimes not be whitened.
But if we can't whiten at print time, then we'd need to whiten at load
time, and if we whiten the entire font, any colored glyphs will get
destroyed too. If you whiten the image selectively, well, we need more
code to target specific squares in the image, and it's kind of a waste
when you need to whiten 30000 12x12 Chinese characters when you're only
going to need a handful, but you don't know which ones.
The solution: Whitening fonts is useless if all the non-colored glyphs
are already white, so we don't need to do it anyway! However, any
existing fonts that have non-white glyphs (and I know of at least one
level like that) will still need to be whitened. So there is now a
font property <white_teeth> that can be specified in the fontmeta,
which indicates that the font is already pre-whitened. If not
specified, traditional whitening behavior will be used, and the font
cannot use colored glyphs.
The MAKEANDPLAY, NO_CUSTOM_LEVELS, and NO_EDITOR defines remove content
or features. However, they then raise several warnings because of some
cases, functions, or variables that end up not being used.
This silences them by using the UNUSED macro, or by adding a default
catch-all case if the define is defined (so unhandled cases will still
raise warnings in a build that doesn't have these defines).
This adds the build type in brackets in `-version` output after e.g.
"VVVVVV v2.4". The build type is MAKEANDPLAY, NO_CUSTOM_LEVELS, or
NO_EDITOR (which are not necessarily mutually exclusive).
This is appended on to the end of the first line so as to not break
Ved's existing `-version` check which only checks if the beginning of
STDOUT is "VVVVVV" followed by any version number.
Ever since VVVVVV was initially ported to C++ in 2.0, it has used surfaces from SDL. The downside is, that's all software rendering. This commit moves most things off of surfaces, and all into GPU, by using textures and SDL_Renderer.
Pixel-perfect collision has been kept by keeping a copy of sprites as surfaces. There's plans for pixel-perfect collision to use masks instead of reading pixel data directly, but that's out of scope for this commit.
- `graphics.reloadresources()` is now called later in `main`, because textures cannot be created without a renderer.
- This commit also removes a bunch of surface functions which are no longer needed.
- This also recaches target textures in certain places for d3d9.
- graphics.images was converted to a fixed-size array.
- fillbox and fillboxabs use SDL_RenderDrawRect instead of drawing an outline using four filled rectangles
- Update my name in the credits
This is useful for developers who may have multiple builds of the game
from various different branches and may easily forget which build of the
game is what.
This shows up in the bottom-right corner of the title screen and also
with the `-version` command-line option, and in the status message
printed when building the game.
colourTransform is a struct with only one member, a Uint32. The issue
with `Uint32`s is that it requires a bunch of bit shifting logic to edit
the colors. The issue with bit shifting logic is that people have a
tendency to hardcode the shift amounts instead of using the shift amount
variables of the SDL_PixelFormat, which makes it annoying to change the
color masks of surfaces.
This commit fixes both issues by unhardcoding the bit shift amounts in
DrawPixel and ReadPixel, and by axing the `Uint32`s in favor of using
SDL_Color.
According to the SDL_PixelFormat documentation (
https://wiki.libsdl.org/SDL2/SDL_PixelFormat ), the logic to read and
draw to pixels from colors below 32-bit was just wrong. Specifically,
for 8-bit, there's a color palette used instead of some intrinsic color
information stored in the pixel itself. But we shouldn't need that logic
anyways because we don't use colors below 32-bit. So I axed that too.
This commit adds most of the code changes necessary for making the game
translatable, but does not yet "unhardcode" nearly all of the strings
(except in a few cases where it was hard to separate added
loc::gettexts from foundational code changes, or all the localization-
related menus which were also added by this commit.)
This commit is part of rewritten history of the localization branch.
The original (unsquashed) commit history can be found here:

This overhauls scriptclass::gamemode massively.
The first change is that it now uses an enum, and enforces using that
enum via using its type instead of an int. This is because whenever
you're reading any calls to startgamemode, you have no idea what magic
number actually corresponds to what unless you read startgamemode
itself. And when you do read it, not every case is commented adequately,
so you'd have to do more work to figure out what each case is. With the
enum, it's obvious and self-evident, and that also removes the need for
all the comments in the function too. Some math is still done on mode
variables (to simplify time trial code), but it's okay, we can just cast
between int and the enum as needed.
The second is that common code is now de-duplicated. There was a lot of
code that every case does, such as calling hardreset, setting Flip Mode,
resetting the player, calling gotoroom and so on.
Now some code may be duplicated between cases, so I've tried to group up
similar cases where possible (most notable example is grouping up the
main game and No Death Mode cases together). But some code still might
be duplicated in the end. Which is okay - I could've tried to
de-duplicate it further but that just results in logic relevant to a
specific case that's located far from the actual case itself. It's much
better to leave things like setting fademode or loading scripts in the
case itself.
This also fixes a bug since 2.3 where playing No Death Mode (and never
opening and closing the options menu) and beating it would also give you
the Flip Mode trophy, since turning on the flag to invalidate Flip Mode
in startgamemode only happened for the main game cases and in previous
versions the game relied upon this flag being set when using a
teleporter for some reason (which I removed in 2.3). Now instead of
specifying it per case, I just do a !map.custommode check instead so it
covers every single case at once.
This makes it so room names are no longer pointers to someone else's
memory, and instead to set them you use `mapclass::setroomname`. If the
string is short enough to fit in a static, no-alloc buffer, then it gets
copied there. Otherwise, a new heap allocation is made that duplicates
the string, and the new pointer is used instead.
This makes it possible for room names to contain arbitrary data whose
origin is temporary (e.g. from a script command that could be added in
the future).
This adds the `-console` command-line option (for Win32 only) so the
game can spawn an attached console window which will contain all console
output.
This is to make it easier for people to debug on Windows systems.
Otherwise, the only way to get console output would be to either compile
the application as a console app (i.e. switch the subsystem to console)
- which is undesirable for regular users as this makes it so a console
is always spawned even when unwanted - or launch the game with shell
arguments that make it so output is redirected to a file.
As a result, color checking support is factored out of vlog_init() into
its own function, even though we don't support colors on Windows.
Using SDL_GetTicks() to seed the Gravitron RNG caused many
reproducibility issues while syncing https://tasvideos.org/7575S . To
fix this, add a frame counter, which is a number that is incremented
every frame and never resets, and use it instead.
If someone needs to switch back to SDL_GetTicks() for old TASes, then
provide the -seed-use-sdl-getticks command-line option for them.
I'm fine with putting the release version in a header file, thus
necessitating the need to recompile every file that includes it if it's
changed, simply because it's not supposed to be changed that often.
The SDL_arraysize is necessary because sometimes we'll have subreleases
(e.g. 2.4.1, 2.4.2, 2.4.3), and who knows, maybe we'll get to 2.10
someday.
This reworks how the commit hash and date are compiled so that if
they're changed (and they're changed often), only one source file needs
to be recompiled in order to update it everywhere in the game, no matter
how many source files use the hash or date.
The commit hash and date are now declared in InterimVersion.h (and they
need `extern "C"` guards because otherwise it results in a link fail on
MSVC because MSVC is stupid).
To do this, what now happens is that upon every rebuild,
InterimVersion.in.c is processed to create InterimVersion.out.c, then
InterimVersion.out.c is compiled into its own static library that is
then linked with VVVVVV.
(Why didn't I just simply add it to the list of VVVVVV source files?
Well, doing it _now_ does nothing because at that point the horse is
already out of the barn, and the VVVVVV executable has already been
declared, so I can't modify its sources. And I can't do it before
either, because we depend on the VVVVVV executable existing to do the
interim version logic. I could probably work around this by cleverly
moving around lines, but that'd separate related logic from each other.)
And yes, the naming convention has changed. Not only did I rename
Version to InterimVersion (to clearly differentiate it from
ReleaseVersion, which I'll be adding later), I also named the files
InterimVersion.in.c and InterimVersion.out.c instead of
InterimVersion.c.in and InterimVersion.c.out. I needed to put the file
extension on the end because otherwise CMake wouldn't recognize what
kind of language it is, and I mean like yeah duh of course it doesn't,
my text editor doesn't recognize it either.
As already described in cc61194bed, as
well as Ved's commits from the last almost two weeks, starting VVVVVV
from Ved for playtesting could be made a lot faster by "preloading" the
game - letting it do all its asset loading in the background without
creating a window - and then waiting until the level is passed in via
stdin. There's only one problem left with this approach: VVVVVV
currently expects the starting position to be passed via command line
arguments, which isn't known yet at the time we'd like to start VVVVVV.
Therefore, this commit allows passing the starting position via the
level XML, instead of via arguments.
The extra XML looks like this, and is added next to the <Data> tag:
<Playtest>
<playx>214</playx>
<playy>112</playy>
<playrx>100</playrx>
<playry>100</playry>
<playgc>0</playgc>
<playmusic>4</playmusic>
</Playtest>
This is handled similarly to how the equivalent arguments are handled:
when the level metadata is loaded for CLI playtesting, we also try to
find this tag, and if it exists, it sets the same variables that the
arguments would have otherwise set.
This is a minor optimization to streamline the experience of Ved
playtesting. Previously, the user would have to wait for all the assets
to load when launching playtesting (most of the time, I suspect, is
taken up by loading music from a vvvvvvmusic blob). With this
optimization, however, the game can be launched in the background and
its assets can be loaded, while it blocks on STDIN input. During this
time, the user in Ved will be choosing where to start playtesting. After
Ved provides STDIN input, then the window will be created and appears
instantaneously.
This also fixes a related issue in which providing an invalid
playtesting level name would result in a brief window flash that gets
instantly destroyed. With this, if the level is invalid then no window
is ever shown at all.
Probably should have done this earlier in 2.3, but better late than
never.
This makes it easier for third-party programs like Ved to detect what
version of the game this is.
Slightly quick-n-dirty for now, I'll de-duplicate the version number
later, and add commit hash and date if applicable.
This removes the magic numbers previously used for controlling the fade
mode, which are really not readable at all unless you already know what
they mean.
0: FADE_NONE
1: FADE_FULLY_BLACK
2: FADE_START_FADEOUT
3: FADE_FADING_OUT
4: FADE_START_FADEIN
5: FADE_FADING_IN
There is also the macro FADEMODE_IS_FADING, which indicates when the
intention is to only check if the game is fading right now, which wasn't
clearly conveyed previously.
I also took the opportunity to clean up the style of any lines I
touched. This included rewriting if-else chains into case-switches,
turning one-liner if-then statements into proper blocks, fixing up
comments, and even commenting the `fademode == FADE_NONE` on the tower
spike checks (which, it was previously undocumented why that check was
there, but I think I know why it's there).
As for type safety, we already get some by transforming the variable
types into the enum. Assignment is prohibited without a cast. But,
apparently, comparison is perfectly legal and won't even give so much as
a warning. To work around this and make absolutely sure I made all
existing comparisons now use the enum, I temporarily changed it to be an
`enum class`, which is a C++11 feature that makes it so all comparisons
are illegal. Unfortunately, it scopes them in a namespace with the same
name as a class, so I had to temporarily define macros to make sure my
existing code worked. I also had to temporarily up the standard in
CMakeLists.txt to get it to compile. But after all that was done, I
found the rest of the places where a comparison to an integer was used,
and fixed them.
This isn't necessary, but it does silence these annoying logs if you
pass an invalid argument or don't have data.zip:
[ERROR] Could not get window size: Invalid renderer
[WARN] Stats not loaded! Not writing unlock.vvv.
[ERROR] Could not get window size: Invalid renderer
[WARN] Settings not loaded! Not writing settings.vvv.
To do this, I've added FILESYSTEM_isInit().
This includes:
- Removing the constructor in favor of actually being able to see that
there's an actual function called being made initializing the struct
- Removing the use of a reference in Screen::init() in favor of using a
pointer
- Adding the struct qualifier everywhere (it's not much typing),
although technically you could typedef it in C, but I'd rather much
not typedef just to remove a tag qualifier
I know earlier I removed the gameScreen extern in favor of using
screenbuffer, but that was only to be consistent. After further
consideration, I have found that it's actually really stupid.
There's no reason to be accessing it through screenbuffer, and it's
probably an artifact of 2.0-2.2 passing stack-allocated otherwise-global
classes everywhere through function arguments. Also, it leads to stupid
bugs where screenbuffer could potentially be NULL, which has already
resulted in various annoying crashes in the past. Although those could
be fixed by simply initializing screenbuffer at the very top of main(),
but, why not just scrap the whole thing anyway?
So that's what I'm doing.
As a nice side effect, I've removed the transitive include of Screen.h
from Graphics.h. This could've been done already since it only includes
it for the pointer anyway, but it's still good to do it now.
SDL_GetTicks64() is a function that got added in SDL 2.0.18, which is
just an SDL_GetTicks() without a value that wraps every ~49 days,
instead wrapping after the sun explodes and kills us all. Oh sorry,
didn't mean to get existential.
For now, put this behind an SDL_VERSION_ATLEAST guard, which will be
removed when SDL 2.0.18 officially releases and we can update to it.
I misread SDL's code and thought that SDL's `begin_code.h` was internal
only to SDL. It turns out you get it when you include basically any
header, such as `SDL_stdinc.h`. So use it directly instead of copying it
for our own.
All system header includes should come before project-specific includes
(includes specific to this game), while coming after the include
specific to the given file (if any; main.cpp doesn't have any).
Without this, `fixedloop` will loop infinitely until focus is regained.
However, Emscripten won't actually know that focus is regained until
`fixedloop` returns.
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.
This fixes the fact that the name of the singular type is plural, but
the name of the plural array is singular. Which has always annoyed me,
too. Also this makes it more clear that custom entities don't have much
to do with the editor.
That's what it is - it's an entity in a custom level. Not something to
do with the editor, necessarily. Like before, the name of the XML
element will remain the same.
This is a pretty hefty commit! But essentially, I made a new editorclass
object, and moved all functions and variables that only get used in the
in-game level editor to that class. This cleanly demarcates which things
are in the editor and which things are just general custom level stuff.
Then I fixed up all the callers. I also fixed up some NO_CUSTOM_LEVELS
and NO_EDITOR ifdefs, too, in several places.
This accompanies the editor.cpp -> CustomLevels.cpp change; I'll be
splitting out the editor functions in the next commit. The name of the
include guard has been changed as well, but not anything else.
Previously, Flip Mode rendering had to be complicated and allocate
another buffer to call FlipSurfaceVerticle, and it was just a mess.
Instead, why not just do SDL_RenderCopyEx, and let SDL flip the screen
for us? This ends up pretty massively simplifying the rendering code.
`-forcecolor` will force color to be on. `-nocolor` will force color to
be off.
And just because I'm a nice person, I've also added British versions of
those flags. As a treat.
This includes the bold as well.
INFO is just default, WARN is yellow, ERROR is red.
We try to automatically detect if the output is a TTY (and thus supports
colors), and don't emit colors if so. Windows 10 supports ANSI color
codes starting with a specific build, but we don't care to emit whatever
garbage Microsoft invented for builds older than that.
On Emscripten, SDL_Delay is implemented as a busy loop. In addition,
everything happens on a single thread. This effectively means that
you have to let Emscripten manage the main loop, since if you do it
yourself the browser will just be frozen.
