"by {author}" is a string that will cause a lot of localization-related
problems, which then become much worse when different languages and
levels can also need different fonts:
- If the author name is set to something in English instead of a name,
then it'll come out a bit weird if your VVVVVV is set to a different
language: "de various people", "por various people", etc. It's the
same problem with Discord bots completing "playing" or "watching" in
their statuses.
- Translators can't always fit "by" in two letters, and level creators
have understandably always assumed, and will continue to assume, that
"by" is two letters. So if you have your VVVVVV set to a language that
translates "by" as something long, then:
| by Various People and Others |
...may suddenly show up as something like:
|thorer Various People and Othe|
- "by" and author may need mutually incompatible fonts. For example, a
Japanese level in a Korean VVVVVV needs to be displayed with "by" in
Korean characters and the author name with Japanese characters, which
would need some very special code since languages may want to add
text both before and after the name.
- It's very possible that some languages can't translate "by" without
knowing the gender of the name, and I know some languages even
inflect names in really interesting ways (adding and even replacing
letters in first names, surnames, and anything in between, depending
on gender and what else is in the sentence).
So to solve all of this, the "by" is now replaced by a 10x10 face from
sprites.png, like a :viridian: emote. See it as a kind of avatar next
to a username, to clarify and assert that this line is for the author's
name. It should be a fairly obvious/recognizable icon, it fixes all the
above problems, and it's a bonus that we now have more happy faces in
VVVVVV.
The last two deprecated functions are:
- Graphics::Print
- Graphics::PrintWrap
These are used a lot, but they're relatively easy to replace, since the
only flag I probably have to immediately worry about is PR_CEN. I do
often need to add PR_FONT_* flags but I don't need to add any
PR_2X/PR_3X/PR_4X anymore.
Only three deprecated functions remain:
- Graphics::Print
- Graphics::PrintWrap
- Graphics::bigprint
I also fixed multiline transparent textboxes having their outlines
overlap the text itself, and fixed textboxclass::padtowidth assuming
glyph widths of 8 (it made the hints at the start of intermission 1
run offscreen for example)
Only four deprecated functions remain:
- Graphics::Print
- Graphics::PrintWrap
- Graphics::bigprint
- Graphics::bprint
Graphics::bprint is the least-used one of them, and after that, the
other functions are used a LOT, but it'll be a lot faster to go through
them, since I have less and less flags to worry about. I'll probably
start using Vim macros again like I did for loc::gettext()ing strings,
or maybe I'll automate this completely.
I migrated all of them to font::print, so they can now be removed.
Six deprecated print functions left! (Of which some are used a whole
lot, it's simpler if the lesser-used ones are gone first.)
I migrated all graphics.len calls over to font::len (and also migrated
prints mainly surrounding those graphics.len's) so the old len function
is now completely removed.
Activity zones need to be in the interface font if the message is from
the system (like Press ENTER to activate terminal, which may be in a
different language) and in the level font if it's a customized message
(setactivitytext).
Graphics::drawtextbox was counting the textbox width and height in
8x8 characters, even including the borders as characters, so it'd need
to be told what the font for the textbox is, and then probably only the
height needs to be adapted to the font and not the width because that's
adapted to the screen width... So just call Graphics::drawpixeltextbox
directly instead. It was already weird enough how actual cutscene
textboxes called Graphics::drawtextbox with x/8, y/8 before the
previous commit, (when you already have the pixel width and height!)
only to have that be a wrapper for drawpixeltextbox by doing x*8, y*8.
Some textboxes need to be in the level font (like room names, cutscene
dialogue, etc - even in the main game), and some need to be in the
interface font (like when you collect a shiny trinket or crewmate). So
most of these textboxes now have graphics.textboxprintflags(font_flag)
as appropriate.
RoomnameTranslator.cpp is now also migrated to the new print system -
in room name translator mode, the room name is now displayed in the 8x8
font if it's untranslated and the level font if it is.
The following functions were moved directly:
- next_wrap
- next_wrap_s
- string_wordwrap
- string_wordwrap_balanced
- string_unwordwrap
These ones will probably still need get a flags argument, except for
string_unwordwrap (since they need to know what font we're talking
about.
The implementation of graphics.len has also been moved to Font.cpp,
but graphics.len still exists for now and is deprecated.
graphics.PrintWrap is now also deprecated. An advantage of the new
version (with flags) is that it'll be possible to do things like put
a border around wrapped text, wrap text at larger scales, etc, but
these things don't work perfectly yet.
This commit also has some other fixes, like the default advance of
6 pixels for characters 0x00-0x1F in 8x8 fonts.
There has always been a mess of different print functions that all had
slightly different specifics and called each other:
Print(x, y, text, r, g, b, cen)
nothing special here, just does what the arguments say
PrintAlpha(x, y, text, r, g, b, a, cen)
just Print but with an alpha argument
PrintWrap(x, y, text, r, g, b, cen, linespacing, maxwidth)
added for wordwrapping, heavily used now
bprint(x, y, text, r, g, b, cen)
prints an outline, then just PrintAlpha
bprintalpha(x, y, text, r, g, b, a, cen)
just bprint but with an alpha argument
bigprint(x, y, text, r, g, b, cen, sc)
nothing special here, just does what the arguments say
bigbprint(x, y, text, r, g, b, cen, sc)
prints an outline, then just bigprint
bigrprint(x, y, text, r, g, b, cen, sc)
right-aligns text, unless cen is given in which case it just
centers text like other functions already do?
bigbrprint(x, y, text, r, g, b, cen, sc)
prints an outline, then just bigrprint
We need even more specifics with the new font system: we need to be
able to specify whether CJK characters should be vertically centered or
stick out on the top/bottom, and we sometimes need to pass in
brightness variables for colored glyphs. And text printing functions
now fit better in Font.cpp anyway. So there's now a big overhaul of
print functions: all these functions will be replaced by font::print
and font::print_wrap (the former of which now exists). These take flags
as their first argument, which can be 0 for a basic left-aligned print,
PR_CEN for centered text (set X to -1!!!) PR_BOR for a border (instead
of functions like bprint and bigbprint), PR_2X, PR_3X etc for scaling,
and these can be combined with |.
Some text, for example [Press ESC to return to editor], fades in/out
using the alpha value, which is passed to the print function. In some
other places (like Press ENTER to teleport, textboxes, trophy text...)
text can fade in or out by direct changes to the RGB values. This means
regular color-adjusted white text can change color, but colored button
glyphs can't, since there's no way to know in the print system what the
maximum RGB values of a specific textbox are supposed to be, so the
only thing it can do is draw the button glyphs at full brightness,
which looks bad. Therefore, you can now also pass in the brightness
value via the flags, with PR_COLORGLYPH_BRI(255).
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 `point` struct was a relic of ActionScript and was added because of
the Flash 'point' object. However, it seems like Simon Roth didn't
realize that SDL has its own point struct.
With this, `Maths.h` can be un-included from a couple headers, which
exposes the fact that `preloader.cpp` was relying on `Maths.h` being
transitively included from `Graphics.h`.
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
In general, "temp" is a bad name because it could mean anything. In this
case the buffer isn't really temporary and it's only used for drawing
the menu with a certain offset, so I made it use a better name. But also
because I'm going to be adding temporary buffers so I don't want the
names to be confused.
`ct` was used to be a variable that a color was temporarily stored in
before being passed to a draw function. But this is unnecessary and you
might as well just have a temporary of the color directly. I guess this
was the practice used because temporaries were apparently really bad in
Flash.
setcolreal() was added in 2.3 to do basically the same thing (set it
directly from entities' realcol attributes). But it's no longer needed.
Correspondingly, Graphics::setcol has been renamed to Graphics::getcol
and now returns an SDL_Color, and Graphics::huetilesetcol has been
renamed to Graphics::huetilegetcol for the same reason.
Some functions (notably Graphics::drawimagecol and
Graphics::drawhuetile) were relying on the `ct` to be implicitly set and
weren't ever having it passed in directly. They have been corrected
accordingly.
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.
I wanted to not complicate the system with different string cases (like
cgettext) if possible, and I have been able to keep the main strings a
simple English=Translation mapping thus far, but apparently strings
like "Rescued!" (which are one string in English), have to be
translated for the correct gender in some languages. So this was a good
time to add support for string cases anyway.
It's a number that can be given to a string to specify the specific
case it's used, to disambiguate identical English keys. In the case of
"Rescued!" and "Missing...", male versions of the string are case 1,
female versions are case 2, and Viridian being missing is case 3. Of
course, if a language doesn't need to use different variants, it can
simply fill in the same string for the different cases.
If any other string needs to switch to different cases: distinguish
them in the English strings.xml with the case="N" attribute (N=1 and
higher), sync language files from the translator menu (existing
translations for the uncased string will simply be copied to all cases)
and change loc::gettext("...") to loc::gettext_case("...", 1),
loc::gettext_case("...", 2), etc.
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.

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.
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.
These were bfont_rect, bg_rect, foot_rect, and images_rect.
bg_rect was only used once to draw the ghost buffer in the editor, but
that was only because Ally didn't know you could just pass NULL in, cuz
the ghost buffer is the same size as the backbuffer.
RGBflip() does the exact same thing as getRGB(), now that all the
surface masks have been fixed. This axes RGBflip() and changes all
callers to use getRGB() instead. It is more readable that way.
By doing this, there is less copy-pasting. Additionally, it is now
easier to search for RGBf() - which is an ENTIRELY different function
than RGBflip() - now that the name of RGBf is no longer the first four
characters of some different, unrelated function. Previously I would've
had to do `rg 'RGBf[^\w]'` which was stupid and awful and I hated it.
Turns out, the r, g, and b arguments don't actually do anything!
There was a call to RGBf() in the function. RGBf() is just getRGB() but
first adds 128 and then divides by 3 to each of the color channels
beforehand. Unfortunately, RGBf() does not have any side effects, and
the function threw away the return value. Bravo.
This also reveals that the website images drawn in the credits in the
main menu are only recolored because of a stale `ct` set by the previous
graphics.bigprint(), and not because any color values were passed in to
drawimagecol()... What fun surprises the game has in store for me every
day.
getBGR, when used in FillRect, was actually passing colors in RGB order.
But now the masks are fixed, so remove it, and fix up all existing
getBGR colors to use getRGB instead.
If it's at all possible to use `const std::string&` when passing
`std::string`s around, then we use it. This is to limit the amount of
memory usage as a result of the frequent use of `std::string`s, so the
game no longer unnecessarily copies strings when it doesn't need to.
I've made a new function, Graphics::do_print(), that does the actual
text printing itself. All the interfaces of the other functions have
been left alone, but now just call do_print() instead.
I also removed PrintOffAlpha() and just calculated the center x-position
in bprintalpha() itself (like bigbprint() does) to make it easier to
de-duplicate code.
I'm honestly not too sure why drawcustompixeltextbox ever existed? All
it seemed to do was draw even more horizontal/vertical tiles to finish
any gaps in the tiling... which was all completely unnecessary and
wasteful, because even the previous drawpixeltextbox implementation
covered all gaps in all custom level map sizes that I tried.
Anyway, that at least gets rid of one copy-pasted function.
This will wrap text on-the-fly, since I will be introducing text that
needs to be wrapped whose length we can't know in advance. (Or we can,
but, that'd be stupid.)
I took the algorithm from Dav999's localization branch, but it's not
like it's a complicated algorithm in the first place. Plus I think it
actually handles words that get too long to fit on a single line better
than his localization branch. The only difference is that I removed all
the STL, and made it more memory efficient (unlike his localization
branch, it does not copy the entire string to make a version with
newline separator characters).
This is a simple change - we draw minimap.png, instead of the generated
custom map, if it is a per-level mounted custom asset.
Custom levels have already been able to utilize minimap.png, but it was
limited - they could do gamemode(teleporter) in a script, and that would
show their customized minimap.png, but it's not like the player could
look at it during gameplay.
I would have done this earlier if I had figured out how to check if a
specific asset was mounted or not.
The config option has been removed. I'm going to implement something
that automatically shows and hides the mouse cursor whenever
appropriate, which is better than a config option.
It's just like bigprint() except it duplicates some of the calculations
because I didn't want to make a bigprintoff() function which would
duplicate even more code. I'm beginning to think these text printing
functions are completely horrible to work with...
While I've decoupled fademode from gamemode starting, being faded out on
the title screen results in a black screen and you being unable to make
any input. So we'll need to store the current fademode in a temporary
variable when going to in-game options, then put it back when we return
to the pause menu. Yes, you can turn on glitchrunner mode during the
in-game options, and then immediately return to the pause menu to
instantly go back to the title screen; this is intended.
Due to frame ordering, putting the fademode back needs to be deferred to
the end of the frame to prevent a 1-frame flicker.
It's actually sufficient enough to do this temporary fademode storage to
fix the whole thing, but I also decided to decouple fademode and
gamemode starting just to be sure.
In 2.2, at render time, the game rendered screenshakes and flashes if
their timers were above 0, and then decremented them afterwards. The
game would also update the analogue filter right before rendering it,
too.
In 2.3, this was changed so the flash and screenshake timers were
unified, and also done at the end of the frame - right before rendering
happened. This resulted in 1-frame flashes and screenshakes not
rendering at all. The other changes in this patchset don't fix this
either. The analogue filter was also in the wrong order, but that is
less of an issue than flashes and screenshakes.
So, what I've done is made the flash and screenshake timers update right
before the loop switches over to rendering, and only decrements them
when we switch back to fixed functions (after rendering). The analogue
filter is also updated right before rendering as well. This restores
1-frame flashes and screenshakes, as well as restores the correct order
of analogue filter updates.
createtextboxreal() is the same as createtextbox(), but with a flipme
parameter added to create text boxes that have their flipme attribute
set to true. createtextbox() just calls createtextboxreal() with flipme
set to false, and createtextboxflipme() just calls createtextboxreal()
with flipme set to true; this is because I do not want to use C++
function overloading.
These default arguments are never used anywhere. And if they were used
anywhere, it'd be better to explicitly say 255,255,255 than make readers
have to look at the header file to see what these default to. Also, this
creates four different overloads of createtextbox(), instead of only
two - but we ought to not be using function overloading anyway.
Like cutscene bars, I've added Graphics::setfade(), to ensure that no
deltaframe rendering glitches happen due to oldfadeamount not being
updated properly.
And indeed, this fixes a deltaframe rendering glitch that happens if you
return to the editor from playtesting on a faded-out screen, then fade
out again (by either re-entering playtesting and then cause a fadeout to
happen again, or by quitting from the editor afterwards). The same
glitch also happens outside of in-editor playtesting if you exit to the
menu while the screen is faded out.
To do this, I've added Graphics::setbars(), to make sure
oldcutscenebarspos always gets assigned when cutscenebarspos is. This
fixes potential deltaframe rendering issues if these two mismatch.
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.
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.
