And further clean up skin api.
It turns out that skin functions must all be in the render libs, and
this results in Skin_Set (was Skin_SetSkin) needs to be accessed via a
function pointer rather than directly :(
This takes care of the double free and also cleans up a lot of the skin
api. However, the gl renderer lost top/bottom colors (for now). Vulkan
skins still don't work yet.
It should be much harder for a malicious server to crash the client
(there were a few holes in there still).
Also, set the fallback (server didn't specify) top/bottom colors to be
such that the default colors from the skin are used instead of white.
cl_player_shadows defaults to 1 thus giving a nice (for the resolution)
shadow of the player (and disables the weapon shadow). Mirrors the
change to nq (I really need to get these last bits merged).
punchangle wasn't getting decayed for two reasons: I had forgotten to
set the flag in qw, and the decayed value was not getting written to
viewstate.
Also, the rotation was misapplied (I had the two quaternions swapped) so
punchangle was being applied to world Y instead of local Y, thus the
seemingly random rolls.
Wandering off to infinity makes for some interesting side effects (in
solid, world partially drawn). Fixes the green screen and missing walls
for the first few seconds of being in a map.
Some of them were actual leaks, but tracking memory should be a lot
easier now. However, there's a lot of room for optimization of
allocations (eg, recylcling of hierarchies. There is now 1 active
allocation (according to tracy) when nq exits: Qgetline's string buffer
(I think an api change is in order).
The main goal of this change was to make it easier to tell when a
hierarchy has been deleted, but as a side benefit, it got rid of the use
of PR_RESMAP. Also, it's easy to track the number of hierarchies.
Unfortunately, it showed how brittle the component side of the ECS is
(scene and canvas registries assumed their components were the first (no
long the case), thus the sweeping changes).
Centerprint doesn't work (but it hasn't for a while).
This relies on my fork of tracy: https://github.com/taniwha/tracy
on the wip-c-vulkan branch. Everything is still rather flaky though.
This necessitated the jump to vulkan 1.2 as a requirement.
This allows tracy to clean up properly. However, Sys_Quit will use the
jump buffer (sys_exit_jmpbuf) only if it has been set, so the use of
Sys_setjmp is optional.
Host_Error and Host_EndGame use setjmp/longjmp to implement an exception
of sorts, but this messes with tracy's state even with cleanup
attributes. However, it turns out that those cleanup attributes are
exactly how gcc implements C++ destructors, and so the standard Unwind
api (part of libgcc) respects them (so long as -fexceptions is enabled
for C). Thus... replace longjmp with an implementation that uses Unwind
to unwind the stack and call the cleanup functions as needed. This is
actually important for more than just tracy as the cleanup attributed
vars can be thread locks.
Tracy is a frame profiler: https://github.com/wolfpld/tracy
This uses Tracy's C API to instrument the code (already added in several
places). It turns out there is something very weird with the fence
behavior between the staging buffers and render commands as the
inter-frame delay occurs in a very strangle place (in the draw code's
packet acquisition rather than the fence waiter that's there for that
purpose). I suspect some tangled dependencies.
They're not quite working (trail path offset is incorrect) but their
pixels are getting to the screen. Also, lifetimes are off for rocket
trails in that as soon as the entity dies, so does the trail.
Although the model subsystem does this too, it does it too late relative
to the video shutdown, resulting in segfaults for glsl due to the
drivers having been unloaded.
By default. Conversion of quake strings needs to be requested (which is
done by nq and qw clients and servers, as well as qfprogs via an
option). I got tired of seeing mangled source code in the disassembly.
Fixing a load of issues related to autoconf and some small source-level issues to re-add clang support.
autoconf feature detection probably needs some addressing - partially as -Werror is applied late.
The use of a static set makes Mod_LeafPVS not thread safe and also means
that the set is not usable with the set iterators after going to a
smaller map from a larger map.
While the insertion of dlights into the BSP might wind up being overly
expensive, the automatic management of the component pool cleans up the
various loops in the renderers.
Unfortunately, (current bug) lights on entities cause the entity to
disappear due to how the entity queue system works, and the doubled
efrag chain causes crashes when changing maps, meaning lights should be
on their own entities, not additional components on entities with
visible models.
Also, the vulkan renderer segfaults on dlights (fix incoming, along with
shadows for dlights).
Setting the cvar to > 0 causes demo playback to stop (via demo_speed 0)
when the read packet count reaches the specified value. Very useful for
debugging rendering glitches that are easily reproduced in a demo.
I guess I wasn't sure how to find all the allocated entities from within
the registry, but it turned out to be trivial. This takes care of leaked
static entities (and, in a later commit, leaked light entities, which is
how I found the problem).
There's still the problem with unused variables when building for
windows because of vulkan debug stuff, but this fixes the important
errors. It actually still works (at least under wine).
It does almost nothing (just puts a non-function button on the screen),
but it will help develop the IMUI code and, of course, come to help with
debugging in general.
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.
I never liked it, but with C2x coming out, it's best to handle bools
properly. I haven't gone through all the uses of int as bool (I'll leave
that for fixing when I encounter them), but this gets QF working with
both c2x (really, gnu2x because of raw strings).
CURLOPT_PROGRESSFUNCTION was deprecated in favor of
CURLOPT_XFERINFOFUNCTION (and the parameters for the callback adjusted).
I'm not sure why this didn't trigger until now.
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).
This means that the component id used for hierarchy references must be
passed to Hierarchy_New and Hierarchy_Copy, but does all an entity to
have more than one hierarchy, which is useful for canvases (hierarchies
of views) in the 3d world (the canvas root would have a 3d hierarchy
reference and a 2d (view) hierarchy reference).
viewstate's time is from cl.time which is not what's used to set
last_servermessage (that uses realtime). After careful investigation, I
found that cl.time is not at all suitable and that the original id code
used realtime (I think it was just me being lazy when I merged the
code). Fixes the stuck net icon.
It's currently used only by the vulkan renderer, as it's the only
renderer that can make good use of it for alias models, but now vulkan
show shirt/pants colors (finally).
Well, sort of: it's still really in the renderer, but now calling
R_AddEfrags automatically updates the visibility structure as necessary,
and deleting an entity cleans up the efrags automatically. I wanted this
over twenty years ago.
