For future PRs, it'll be very nice to have full control over how VVVVVV
gets drawn to the window. This means we can use the entire window size
for things like touch input, drawing borders, or anything we want.
This removes Graphics::textboxwrap(), as it is now an unused function.
Additionally, this removes the return value of textboxclass::wrap(), as
it is also now unused.
This adds an attribute to textboxclass to allow a text box to keep an
index that references another text box inside the graphics.textboxes
std::vector.
This is needed because the second text box of a "You have found a
shiny trinket!" or "You have found a lost crewmate!" pair of text boxes
explicitly relies on the height of the first text box. With this, I have
moved those text boxes over to the new text box translation system.
Since the update order now matters, I added a comment to
recomputetextboxes() that clarifies that the text boxes must be updated
in linear order, starting from 0.
These seemed annoying to do without copy-pasting, because I didn't want
to make a separate function for every single dialogue, and I didn't know
how to pass through the English text, until I realized that I can just
use the existing original.lines vector in the text box to store the
English text. After that, getting it translated on-the-fly isn't too
bad.
This transfers the responsibility of the adjust() call to
applyposition().
This is because cutscene text boxes (TEXTTRANSLATE_CUTSCENE) will have
adjust() called, but all other text boxes won't. And I can't place the
adjust() call inside applyposition(), because adjust() also calls
applyposition(), and that leads to an infinite loop which leads to a
stack overflow, so I had to remove the applyposition() call from
adjust(), and replace the other existing call to
Graphics::textboxadjust() with Graphics::textboxapplyposition(), and
then remove Graphics::textboxadjust() function because it's no longer
used.
This adds a way to save the text box state of the crew remaining, ACTION
prompt, etc. text boxes by just letting there be a function that is
called to retranslate the text box when needed.
It also adds a way to ignore translating a text box and to leave it
alone, in case there's actually no text in the text box, which is the
case with Level Complete and Game Complete.
Both ways are now in an enum, TextboxTranslate. The former is
TEXTTRANSLATE_FUNCTION and the latter is TEXTTRANSLATE_NONE. The
existing way of translating text boxes became TEXTTRANSLATE_CUTSCENE,
since it's only used for cutscene scripts.
Here's a quick guide to the three ways of creating a text box now.
- TEXTTRANSLATE_NONE: You must call
graphics.textboxoriginalcontextauto() to save the existing text to the
original context of the text box, as that will be copied back to the
text box after the text of the text box is updated due to not having a
translation.
- TEXTTRANSLATE_CUTSCENE: Translates the text from cutscenes.xml, and
overrides the spacing (padding and text centering). Shouldn't need to
be used outside of scriptclass.
- TEXTTRANSLATE_FUNCTION: You must pass in a function that takes in a
single parameter, a pointer to the textboxclass object to be modified.
General advice when retranslating text is to clear the `lines` vector
and then push_back the retranslated text. The function is also solely
responsible for spacing.
In most cases, you will also need to call
graphics.textboxapplyposition() or graphics.textboxadjust() afterwards.
(Some text boxes shouldn't use graphics.textboxadjust() as they are
within the 10-pixel inner border around the screen that
textboxclass::adjust tries to push the text box out of.)
This commit doesn't fix every text box just yet, though. But it fixes
the Level Complete, Game Complete, crew remaining, and ACTION prompt
text boxes, for a start.
This allows switching languages while a text box is on screen by saving
the necessary state for a text box to be retranslated when the language
is switched.
This saves the state of the position and direction of the crewmate that
the text box position is based off of (if applicable), and the text
case of the text box, the script name of the script, and the original
(English) lines of the text box. I did not explicitly label the original
lines as English lines except in a main game context, because
technically, custom levels could have original lines in a different
language.
Unfortunately, this doesn't work for every text box in the game.
Notably, the Level Complete, Game Complete, number of crewmates
remaining, trinket collection, Intermission 1 guides, etc. text boxes
are special and require further fixes, but that will be coming in later
commits.
Originally, I was thinking of adding a notification text that you took a
screenshot, but this is better because it is language-agnostic and it
doesn't contribute to potential UI clutter/clashing.
It flashes yellow if the screenshot successfully saved, and red if it
didn't.
The plan is to have Steam screenshots always be 2x, but in the VVVVVV
screenshots directory (for F6 keybind) save both 1x and 2x.
Again, just for now, the 2x screenshot is being saved to a temporary
location for testing and will get proper timestamps later.
"But people already have screenshot tools", you might protest. The
rationale is simple: If you play with any video setting other than 1x
windowed (no stretching and no letterbox), then your screenshot will be
too big if you want the internal resolution of 320x240, and downscaling
will be an inconvenience.
The point is to make screenshots based off of internal resolution so
they are always pixel perfect and ideally never have to be altered once
taken.
I've added the keybind of F6 to do this.
Right now it saves to a temporary test location with the same filename;
future commits will save to properly-timestamped filenames.
This is mostly so people making levels in an RTL language have a more
pleasant and logical experience. If roomtext is placed in a level set
to RTL, it will get p1=1, which makes that roomtext right-aligned.
Because, imagine for English you click to place roomtext, and the text
runs left of where you clicked, which wouldn't be logical.
Since it's an entity-bound property, switching RTL on and off either in
the editor or via a script does not affect existing entities.
`levelcomplete` and `gamecomplete` were hardcoded using textbox colors
which were offset by 1. This PR fixes that, no longer requiring
slightly-off colors, and instead adding a new property to textboxes
which tell the game to display either level complete or game complete.
This commit adds a system for displaying sprites in textboxes, meant to
replace the hardcoded system in the main game. This does not support
levelcomplete.png and gamecomplete.png yet, which will most likely just
be special cases.
Language folders can now have a graphics folder, with these files:
- sprites.png and flipsprites.png: spritesheets which contain
translated versions of the word enemies and checkpoints
- spritesmask.xml: an XML file containing all the sprites that should
be copied from the translated sprites and flipsprites images to
the original sprites/flipsprites.
This means that the translated spritesheets don't have to contain ALL
sprites - they only have to contain the translated ones. When loading
them, the game assembles a combined spritesheet with translated sprites
replacing English ones as needed, and this sheet is used to visually
substitute the normal sprites at rendering time.
It's important to note that even if 32x32 enemies have pixel-perfect
hitboxes, this is only a visual change. This has been discussed several
times on Discord - basically we don't want to give people unfair
advantages or disadvantages because of their language setting, or
change existing gameplay and speedruns tactics, which may depend on the
exact pixel arrangements of the enemies. Therefore, the hitboxes are
still based on the English sprites. This should be basically
unnoticeable for casual players, especially with some thought from
translators and artists, but there will be an option in the speedrunner
menu to display the original sprites all the time.
I removed the `VVV_freefunc(SDL_FreeSurface, *tilesheet)` in
make_array() in Graphics.cpp, which frees grphx.im_sprites_surf and
grphx.im_flipsprites_surf. Since GraphicsResources::destroy() already
frees these, it looks like the only purpose the one in make_array()
serves is to do it earlier. But now we need them again later (when
switching languages) so let's just not free them early.
This commit removes the `NO_EDITOR` and `NO_CUSTOM_LEVELS` defines,
which cleans up the code a lot, and they weren't really needed anyways.
This commit also disables the editor on the Steam Deck, and adds a
program argument to re-enable the editor, `-enable-editor`.
Turns out `graphics.drawrect` exists. Well, not anymore!
This was another function from before the renderer rewrite which tried
to draw a rectangle by using four filled rectangles. We can draw
outline rectangles properly now, so let's make sure everywhere does it!
As #974 states, the lab background only ever uses the first generated
value from `backboxint`, so let's change it to a normal variable
instead of an array. Also, stars don't need their width/height set to
2 constantly... they never change in the first place, Terry!
Some code still used rectangles to draw things like lines and pixels,
so this commit adds more draw functions to support drawing lines and
pixels without directly using the renderer.
Aside from making generated minimaps draw points instead of 1x1
rectangles, this commit also batches the point drawing for an
additional speed increase.
The clock on the Game Saved quicksave screen has always been upside-down
in Flip Mode. And technically, the trinket was too, but this was
unnoticeable because the default trinket sprite is symmetrical.
To fix this, draw flipsprites.png if these sprites are being drawn in
Flip Mode instead of sprites.png.
This will actually do several things:
(1) Make the tile size checks apply to the appropriate graphics files
once again.
(2) Make the game print a fallback error message if the error message
hasn't been set on the levelDirError error screen.
(3) Use levelDirError for graphics errors too.
(4) Make the error message for tile size checks failing specify both
width and height, not just a square dimension.
(5) Make the error messages mentioned above translatable.
It turns out that (1) didn't happen after #923 was merged, since #923
removed needing to process a tilesheet into a vector of surfaces for all
graphics files except sprites.png and flipsprites.png. Thus, the game
ended up only checking the correct tile sizes for those files only.
In the process of fixing this, I also got rid of the PROCESS_TILESHEET
macros and turned them into two different functions: One to make the
array, and one to check the tile size of the tilesheet.
I also did (2) just in case FILESYSTEM_levelDirHasError() returns false
even though we know we have an error.
And (3) is needed so things are unified and we have one user-facing
error message system when users load levels. To facilitate this, I
removed the title string, since it's really not needed.
Unfortunately, (1) doesn't apply to font.png again, but that's because
of the new font stuff and I'm not sure what Dav999 has in store for
error checking. But that's also why I did (4), because it looks like
tile sizes in font.png files can be different (i.e. non-square).
For some reason, the accessibility option that was meant to disable
flashes doesn't disable ALL flashes, only screen flashes and screen
shaking. This commit disables a lot more, most importantly randomness
in colors, the player flashing on death/respawn, and teleporters
flashing.
Misa asked me if this should only work for non-transparent textboxes,
and it shouldn't - that was kind of an oversight.
To make it work for transparent textboxes as well, I made a little
restructuring to avoid duplicating the code - fill_buttons() is now
called textbox_line(), and it replaces the direct accessing of the
textbox lines in the printing loops. The code that checks the width
of the textbox does not need to be copied, since the text box is
naturally not drawn for transparent text boxes.
There's a few places where textboxes are constructed through code, but
they pass in the color's RGB values in manually. This commit
unhardcodes most of them them, replacing them with a color lookup.
The ones that weren't changed are special cases, like `175, 174, 174`.
Violet's dialogue now looks like this:
squeak(purple)
text(purple,0,0,2)
Remember that you can press {b_map}
to check where you are on the map!
position(purple,above)
textbuttons()
speak_active
The new textbuttons() command sets the next textbox to replace {b_map}
with the map button, and {b_int} with the interact button. The
remaining keys would be added as soon as they need to be added to
ActionSets.h as well.
Tools were a mess, spread all over the code with hundreds of `else-if`
statements. Instead of magic numbers denoting tools, an enum has been
created, and logic has been extracted into simple switch/cases, shared
logic being deduplicated.
The base of a state system for the editor has been created as well,
laying a good path for further organization improvements. Because of
this, the entire editor no longer gets drawn underneath the menus,
except for a few pieces which I haven't extracted yet. Either way,
this should be good for performance, if that was a concern.
It turns out this texture is only used as a temporary texture to draw
the screen with an offset before rendering it to the output target.
I thought it was used for drawing the map menu animation, but that was
only true of `tempBuffer`, and is no longer true of the new render
system.
The style we have here is that functions with no arguments are to have
explicit `void` arguments, even though this doesn't apply in C++,
because it does apply in C.
Unfortunately, some have slipped through the cracks. This commit fixes
them.
Drawing a texture onto itself seems to produce issues on Metal.
To fix this, use a temporary texture instead, that then gets drawn onto
the original texture.
Fixes#927.
I'm going to soon be creating an actually temporary texture, so having
two textures named "temp" would get confusing. This is also a good
chance to correct the name of this texture, because it's not really
temporary, but it's used for map menu animation rendering.
"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
