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.
This is the variable dwgfx.translucentroomname and <translucentroomname>
in unlock.vvv.
This lets you see through the black background of the roomname at the
bottom of the screen, i.e. it makes the roomname background translucent.
So you can see if someone decides to hide pesky spikes there.
The roomname background used to just be a simple SDL_Rect that was drawn
using SDL_FillRect with a color of 0. Unfortunately, it seems that you
cannot use transparent colors with SDL_FillRect, it just defaults to
being fully opaque. However, you CAN draw surfaces with translucency,
which seems like the easiest thing to do. But the first step is to
convert the roomname background to an SDL_Surface.
This replaces the FillRect()s with SDL_BlitSurface() in the three places
roomnames are drawn: in towerrender, in gamerender, and in editorrender.
