Fixes axis inputs being half what they should be. Can't quite get +1,
though (need to figure something out for the positive axis range being
slightly smaller than the negative range).
It's very much a hack, but it will do for now until I can rewrite the
whole thing: it's not at all thread safe, but it is over eight years
old and has survived a lot of bit-rot.
The old math functions from quake and quakeworld don't belong with the
newer ones as their presence in the same object file causes invalid
builtin warnings when pr_cmds isn't present.
With some hacks that are not included (plan on handling events and
contexts properly), button inputs, including using listeners, are
working nicely: my little game is working again. While the trampoline
code was a bit repetitive (and I do want to clean that up), connecting
button listeners directly to Ruamoko instance methods proved to be quite
nice.
mtwist_rand_0_1 produces numbers in the range [0, 1) and
mtwist_rand_m1_1 produces numbers in the range (-1, 1). The numbers will
not be denormal, so the distribution should be fairly uniform (as much
as Mersenne Twister itself is), but this needs proper testing.
0 is included for the mtwist_rand_0_1 as it seems useful, but -1 is not
included in mtwist_rand_m1_1 in order to keep the extremes of the
distribution balanced around 0.
And create rua_game to coordinate other game builtins.
Menus are broken for key handling, but have been since the input rewrite
anyway. rua_input adds the ability to create buttons and axes (but not
destroy them). More work needs to be done to flesh things out, though.
Until now, the new qwaq startup was used only in command-line tools and
console applications where things like Ruamoko security and having a
hunk were not an issue. Now the start up code (qwaq-*.c) can specify
that Ruamoko is to be secured and provide a hunk on a per-thread basis,
and the thread data is passed into the progs code via a progs resource.
It now uses the advanced command line parsing used by qwaq-curses and
qwaq-cmd, but currently disables multi-threading (I don't want to deal
with threading in the engine just yet). The int file is -graphics
because qwaq-x11 is really just the X11 target, qwaq-win is built for
windows, but they use the same basic startup (I hope).
This takes care of the global variables to a point (there is still the
global struct shared between the non-vulkan renderers), but it also
takes care of glsl's points-only rendering.
After yesterday's crazy marathon editing all the particles files, and
starting to do another big change to them today, I realized that I
really do need to merge them down. All the actual spawning is now in the
client library (though particle insertion will need to be moved). GLSL
particle rendering is semi-broken in that it now does only points (until
I come up with a way to select between points and quads (probably a
context object, which I need anyway for Vulkan)).
This may seem a little contradictory, but it's due to the difference
between a high level (engine) render pass and a Vulkan render pass
object (and quite likely a poor choice in names for the high level
object). This is necessary for supporting compute shader dispatches as
they cannot be submitted inside a Vulkan render pass.
This has the advantage of getting entity_t out of the particle system,
and much easier to read math. Also, it served as a nice test for my
particle physics shaders (implemented the ideas in C). There's a lot of
code that needs merging down: all but the actual drawing can be merged.
There's some weirdness with color ramps, but I'll look into that later.
They should increment by one for each pic, not 4 (I think some fluff
remaining from copying glsl's draw code).
I noticed the problem when I saw large gaps of 0s in the vertex data in
renderdoc.
This gets the crosshair working in Vulkan (next commit) and fixes issues
with changing the palette (though I've never seen a different palette
for quate, there's still the change from "all black" to an actual
palette).
This was needed to get crosshaircolor working correctly, but is likely
another step towards resizable windows (the listener set types are
generic for any viddef event, not just palette changes).
Holding onto the pointer is not a good idea, and it is read-only as
direct manipulation of the world matrix is not supported. However, this
is useful for passing the matrix to the GPU.
This means color, emission, and translucent. Fixes the HOM issues on my
VersaPro (but halves the frame-rate... definitely need to bring back the
forward renderer as an option).
