Graphics::drawmenu() no longer has copy-pasted code for each individual
case. Instead, the individual cases have their own adding on to common
code, which is far easier to maintain.
Also, the only difference Graphics::drawlevelmenu() does is in some
y-positioning stuff. There's no reason to make it a whole separate
function and duplicate everything AGAIN. So it's been consolidated into
Graphics::drawmenu() as well, and I've added a boolean to draw a menu
this way if it's the level menu.
These unused vars are:
- Graphics::bfontmask_rect
- Graphics::backgrounds
- Graphics::bfontmask
- GraphicsResources::im_bfontmask
While it seems that Graphics::backgrounds was indexed in
Graphics::drawbackground(), in reality there was never anything in that
vector and thus actually using it would cause a segfault.
The problem we're running into is entirely contained in the Screen - we need to
either decouple graphics context init from Screen::init or we need to take out
the screenbuffer interaction from loadstats (which I'm more in favor of since we
can just pull the config values and pass them to Screen::init later).
The game for some reason had this thing where it would not draw the
diagonal background tiles if you had animated backgrounds turned off.
Which is weird, because spikes with that background are still drawn as
spikes with that background. And also, it doesn't do this for any of the
tower hallway rooms, which is inconsistent.
Better to simplify the logic in Render.cpp anyways by removing
graphics.drawtower_nobackground() and making it really clear what
exactly we'll do if backgrounds are turned off. ("Aren't we already not
drawing the background? What's this _nobackground() function for?")
All menus had a hardcoded X position (offset to an arbitrary starting
point of 110) and a hardcoded horizontal spacing for the "staircasing"
(mostly 30 pixels, but for some specific menus hardcoded to 15, 20 or
something else). Not all menus were centered, and seem to have been
manually made narrower (with lower horizontal spacing) whenever text
ran offscreen during development.
This system may already be hard to work with in an English-only menu
system, since you may need to adjust horizontal spacing or positioning
when adding an option. The main reason I made this change is that it's
even less optimal when menu options have to be translated, since
maximum string lengths are hard to determine, and it's easy to have
menu options running offscreen, especially when not all menus are
checked for all languages and when options could be added in the middle
of a menu after translations of that menu are already checked.
Now, menus are automatically centered based on their options, and they
are automatically made narrower if they won't fit with the default
horizontal spacing of 30 pixels (with some padding). The game.menuxoff
variable for the menu X position is now also offset to 0 instead of 110
The _default_ horizontal spacing can be changed on a per-menu basis,
and most menus (not all) which already had a narrower spacing set,
retain that as a maximum spacing, simply because they looked odd with
30 pixels of spacing (especially the main menu). They will be made even
narrower automatically if needed. In the most extreme case, the spacing
can go down to 0 and options will be displayed right below each other.
This isn't in the usual style of the game, but at least we did the best
we could to prevent options running offscreen.
The only exception to automatic menu centering and narrowing is the
list of player levels, because it's a special case and existing
behavior would be better than automatic centering there.
Similar to Graphics::map_tab(), this ensures that I don't have to
copy-paste printing the map options for every single game.menupage case
I want, and in this case that's a good thing because there'll be 4
game.menupage cases I'll be using.
This function is useful to de-duplicate all the map page names at the
bottom, which are MAP, CREW/SHIP/GRAV, STATS, and SAVE. If selected, it
will surround the text in square brackets and automatically handle the
positioning.
Shamelessly copy-pasted from Dav999's localization branch.
This adds Graphics::crewcolourreal(), which is like the
entityclass::crewcolour() that the editor already uses, except for the
real color instead of the color ID. Also, editorclass now has an
attribute `entcolreal` so enemy colors don't update more than 30 frames
a second.
Currently it interpolates it based on the current state of game.swngame,
but when game.swngame changes the interpolation doesn't know that it has
JUST changed or anything. So add a kludge variable to fix this
off-by-one.
These colors were of the colors of each crewmate, the inactive crewmate
color, and the color of the trinket and clock on the quicksave/summary
screens.
These colors all used fRandom() and so kept updating too quickly because
they would be recalculated every time the delta-timestep render function
got called, which isn't ideal. Thus, I've had to add attributes onto the
Graphics class to store these colors and make sure they're only
recalculated in logic functions instead.
Thankfully, the color used for the sprites on the time trial results
screen doesn't use fRandom(), so I don't have to worry about those.
There's a new version of Graphics::drawsprite() that takes in a pre-made
color already, instead of a color ID. As well, I've also added
Graphics::updatetitlecolours() to update these colors on the title
screen.
Okay, so the problem here is that Graphics::setcol() is called right
before a sprite is drawn in a render function, but render functions are
done in deltatime, meaning that the color of a sprite keeps being
recalculated every time. This only affects sprites that use fRandom()
(the other thing that can dynamically determine a color is help.glow,
but that's only updated in the fixed-timestep loop), but is especially
noticeable for sprites that flash wildly, like the teleporter, trinket,
and elephant.
To fix this, we need to make the color be recalculated only in the
fixed-timestep loop. However, this means that we MUST store the color of
the sprite SOMEWHERE for the delta-timesteps to render it, otherwise the
color calculation will just be lost or something.
So each entity now has a new attribute, `realcol`, which is the actual
raw color used to render the sprite in render functions. This is not to
be confused with their `colour` attribute, which is more akin to a color
"ID" of sorts, but which isn't an actual color.
At the end of gamelogic(), as well as when an entity is first created,
the `colour` is given to Graphics::setcol() and then `realcol` gets set
to the actual color. Then when it comes time to render the entity,
`realcol` gets used instead.
Gravitron squares are a somewhat tricky case where there's technically
TWO colors for it - one is the actual sprite itself and the other is the
indicator. However, usually the indicator and the square aren't both
onscreen at the same time, so we can simply switch the realcol between
the two as needed.
However, we can't use this system for the sprite colors used on the
title and map screen, so we'll have to do something else for those.
In order to make sure colors don't update more than 1000/34 frames per
second, I'll have to move the color-setting part of this function
somewhere else.
These special images are the crewmates, Level Complete, and Game
Complete images. They flashed depending on if you were lucky and
happened to got your delta-timesteps just right when text boxes were
fading in and out.
Honestly, I'm surprised text box fading in/out hasn't ran into this
issue before. It's insane luck that this issue hasn't occurred before or
anything.
Well, anyways, to fix this, there's now an attribute `allowspecial` on
text boxes, and an optional parameter of the same name for
Graphics::createtextbox(). This attribute is the only thing that will
let these special text box images render. And any createtextbox()es that
utilize these special images have been updated accordingly.
Now it's really, really smooth. Except for like the last frame when it
goes down, which I sometimes didn't notice (but maybe it didn't happen
every time due to being lucky on the delta timesteps or something,
whatevs.)
Otherwise the screen will shake too fast for my liking.
Also I'm planning to add an FPS limiting option later (because right
now, un-capping the FPS is pretty wasteful and eats up lots of
resources, especially since I have only a 60hz monitor), and it'd feel
weird if screen shaking updated every delta timestep.
I've added a function Graphics::lerp() which simply interpolates between
two values given a certain alpha value. It's just like drawing a
straight line between two points.
Also, Graphics now has an `alpha` attribute, and it is set on every
deltatime update to be used in linear interpolation.
The only class that actually needs its i/j/k kept is scriptclass,
because some custom levels rely on it for creating custom activity
zones. So I haven't touched that.
Other than that, there's no chance that anything important relies on
i/j/k in any other class. For that to be the case, it would have to use
i/j/k without initializing it beforehand, and that can simply be
detected by removing the attribute from the header file and seeing where
the compiler complains. And the compiler complains only about cases
where it's initialized first. (Note that due to this check, I *haven't*
removed Graphics's `m` as it precisely does exactly this, using it
without initializing it first.)
Interestingly enough, otherlevelclass and towerclass have unused i/k
variables for whatever reason.
A few months ago, I added ghosts to the VVVVVV: Community Edition editor. I was told recently I should think
about upstreaming it, and with Terry saying go ahead I finally ported them into VVVVVV. There's one slight
difference however--you can choose whether you have them or not in the editor's settings menu. They're off by
default, and this is saved to the save file.
Anyway, when you're playtesting, the game saves the players position, color, room coordinates and sprite every 3
frames. The max is 100, where if it tries to add more, the oldest one gets removed.
When you exit playtesting, the saved positions appear one at a time, and you can use the Z key to speed it up.
[Here's a video of them in action.](https://o.lol-sa.me/4H21zCv.mp4)
It's less code being copied and pasted, especially since for my
over-30-FPS patch I would have to make a separate function for each if
both of them were still there, but if they're unified into one then I
will only have to make one more function.
And since map.scrolldir is now used outside of GAMEMODE, we'll need to
reset it in hardreset() and when exiting playtesting.
This de-duplicates the screen effects rendering code by putting it
inside a function, Graphics::renderwithscreeneffects(), and using that
instead of copy-pasted code.
This removes lots of duplicated code that drawtowerentities() did,
because all that really changed was accounting for map.ypos (which can
be done conditionally) and where and when the room wrapped (which can
also be done conditionally).
This removes the variables graphics.ntextbox, as well as removing
'active' from each text box object. Thus, all text boxes are really
real, and you don't have to check its 'active' variable.
Unlike, say, the scriptclass i/j/k stuff, these tempstrings are only
purely visual, and there's no known glitches to manipulate them anyway.
Thus I think it's safe to make this cleanup.
The 'r', 'g', and 'b' arguments do absolutely nothing. Except unlike
Graphics::drawtile(), there's only one version of Graphics::drawtile2(),
so just remove those args and update callers.
The 'r', 'g', and 'b' arguments do absolutely nothing, even though
they're used in the version of Graphics::drawtile() that's more used. So
delete the other version without those extra arguments, and then remove
the extra arguments from the remaining version. And then update callers.
This removes global args from all functions on the Graphics class.
Callers of those functions in other files have been updated accordingly.
Of course, since Graphics.cpp is already in the Graphics namespace,
I do not need to change all 'dwgfx' to 'graphics' in Graphics.cpp.
I've decided to call dwgfx/game/map/obj/key/help/music the "global args".
Because they're essentially global variables that are being passed
around in args.
This commit removes global args from all functions on the Game class,
and deals with updating the callsites of said functions accordingly. It
also renames all usages of 'dwgfx' in Game.cpp to 'graphics', since the
global variable is called 'graphics' now.
Interesting to note, I was removing the class defines from Game.h, but
it turns out that Graphics.h depends on the mapclass and entityclass
defines from Game.h. And also Graphics.h spelled mapclass wrong (it
forgot the "class") so I just decided to use that existing line instead.
This is only temporary and after all is said and done, at the end of
this pull request those class defines will be gone.
This makes the "[Press ENTER to return to editor]" fade out after a few frames, allowing screenshots of custom levels to be cleaner and to make sure nothing is obscured while the user is editing their level.
This commit also adds alpha support in BlitSurfaceColoured, where it takes into account the alpha of the pixel *and* the alpha of the color.
`graphics::getRGBA(r,g,b,a)` was added to help with this.
This uses utfcpp combined with a custom font, in the form of a PNG and text file. By default, the game acts exactly as it did before; custom fonts can be provided by third parties.
This commit makes `help`, `graphics`, `music`, `game`, `key`, `map`, and
`obj` essentially static global objects that can be used everywhere.
This is useful in case we ever need to add a new function in the future,
so we don't have to bother with passing a new argument in which means we
have to pass a new argument in to the function that calls that function
which means having to pass a new argument into the function that calls
THAT function, etc. which is a real headache when working on fan mods of
the source code.
Note that this changes NONE of the existing function signatures, it
merely just makes those variables accessible everywhere in the same way
`script` and `ed` are.
Also note that some classes had to be initialized after the filesystem
was initialized, but C++ would keep initializing them before the
filesystem got initialized, because I *had* to put them at the top of
`main.cpp`, or else they wouldn't be global variables.
The only way to work around this was to use entityclass's initialization
style (which I'm pretty sure entityclass of all things doesn't need to
be initialized this way), where you actually initialize the class in an
`init()` function, and so then you do `graphics.init()` after the
filesystem initialization, AFTER doing `Graphics graphics` up at the
top.
I've had to do this for `graphics` (but only because its child
GraphicsResources `grphx` needs to be initialized this way), `music`,
and `game`. I don't think this will affect anything. Other than that,
`help`, `key`, and `map` are still using the C++-intended method of
having ClassName::ClassName() functions.
