It's usually desirable to hide the cursor when playing quake, but when
using the console, or in various other states, being able to see the
cursor can be quite important.
And other graphics versions too, of course. A lot of it feels rather
like a hack, but I think the entire canvas/console setup and console
related event handling may need a rethink (it's not horribly wrong, but
it doesn't feel right), particularly the initial sizing and binding for
toggling the console.
This will make it easy for client code to set up data needed by the
console before the console initializes. It already separates console
cvar setup and initialization, which has generally been a good thing.
Instead of creating new entities for the text views. This approximately
halves the number of entities required to display flowed text, but also
tests the ability to have an entity in multiple hierarchies (the goal of
the ECS component and system changes).
Font and text handling is very much part of user interface and at least
partially independent of rendering, but does fit it better with GUI than
genera UI (ie, both graphics and text mode), thus libQFgui as well as
libQFui are built in the ui directory.
The existing font related builtins have been moved into the ruamoko
client library.
This puts the hierarchy (transform) reference, animation, visibility,
renderer, active, and old_origin data in separate components. There are
a few bugs (crashes on grenade explosions in gl/glsl/vulkan, immediately
in sw, reasons known, missing brush models in vulkan).
While quake doesn't really need an ECS, the direction I want to take QF
does, and it does seem to have improved memory bandwidth a little
(uncertain). However, there's a lot more work to go (especially fixing
the above bugs), but this seems to be a good start.
The palette is a modified version of the default VGA colormap as
explained by Noah Johnson (https://github.com/canidlogic/vgapal) and the
generation code is heavily influenced by his code. However, I've
reversed the HSV groups so I could have the pure bright colors in the
fullbright range and added a few colors in the 248-255 range (mostly
greens and ambers meant to be close to the old phosphor monitors).
The colormap is generated by laying the colors from the palette across
the middle of the map (rows 31 and 32) then linearly interpolating from
0 to the color, and the color to 2x the color (clamped) and then
converting back to a palette. Mr Fixit actually looks ok still in the
software renderer (unaffected in the others) though quakeguy is a hoot
in all the renderers :).
This replaces *_NewMap with *_NewScene and adds SCR_NewScene to handle
loading a new map (for quake) in the renderer, and will eventually be
how any new scene is loaded.
The goal is to have somewhere to put entities so they can be rendered. I
suspect I could have used a bsp tree to partition space for frustum
culling, but it's probably not worth it at this stage (but shouldn't
require any changes to the engine: just the model).
This is the bulk of the work for recording the resource pointer with
with builtin data. I don't know how much of a difference it makes for
most things, but it's probably pretty big for qwaq-curses due to the
very high number of calls to the curses builtins.
Closes#26
This is part of the work for #26 (Record resource pointer with builtin
function data). Currently, the data pointer gets as far as the
per-instance VM function table (I don't feel like tackling the job of
converting all the builtin functions tonight). All the builtin modules
that register a resources data block pass that block on to
PR_RegisterBuiltins.
This will make it possible for the engine to set up their parameter
pointers when running Ruamoko progs. At this stage, it doesn't matter
*too* much, except for varargs functions, because no builtin yet takes
anything larger than a float quaternion, but it will be critical when
double or long vec3 and vec4 values are passed.
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.
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).
