qvmcall64 has its own custom calling convention due to pushing all non-volatile registers to the stack. The game uses set/longjmp which on Windows uses "RtlUnwindEx" to unwind the callstack. qvmcall64 cannot be unwound by default due to the custom calling convention. To allow unwinding, we need to add custom SEH unwind data to the function.
Not all non-volatile registers were actually saved and restored, leading to a few registers being trashed after calling the vm instructions.
All non-volatile registers have been added.
The affect of my 2017 commit c3e64d3806
"Make bots only use q3tourney6 crusher to kill their enemy"
made it easier to beat the last map of the Quake 3 single player
campaign. It was mainly intended for CTF and Team Arena gametypes
variants of the map. (Team deathmatch is usually treated as deathmatch
with teams rather than an actual team based gametype.)
Restore original difficulty for non-CTF/Team Arena gametypes; bot will
crush player even if bot hasn't seen the player since either they or
player respawned. [This is not good in CTF where all five bots on the
team suddenly flip around and shoot at the crusher trigger.]
Team deathmatch still uses my added behavior of not triggering crusher
if there is a teammate under the crusher.
Pulseaudio audio capture didn't stop when paused on Debian 8 but works
on Debian 9 when using the same manual SDL build. So it seems to have
been an issue in pulseaudio, not SDL.
There is no need for a tentative definition in this case. By providing
an explicit initializer, the resulting definition has the same effect
as before, but is no longer tentative. This avoids easy errors
resulting from multiple tentative definitions in different translation
units. (Previous compilers permitted those common errors, but GCC 10
rejects them by default.)
My 2017 commit f7c3276 ("Fix g_teamAutoJoin and g_teamForceBalance")
caused BroadcastTeamChange() to be run an extra time when bots connect.
This caused a duplicate center print message to be sent to all clients.
g_teamAutoJoin 1 sent an extra center print when any player or bot
connects. Though that is the original behavior from Team Arena.
Team set during connection no longer sends broadcast as it will be
sent later in ClientConnect().
Reported by Pascal Brochart (pbrochart) as causing clients to be
kicked due to server command overflow if many bots join at the
same time.
If bots join before the local client (dedicated server) the bots would
not be listed in the Q3A team orders menu and so they could not be given
orders using the menu.
The Q3A team orders menu got local client's team while looping through
all clients. Ignoring any bots with clientnum lower than the local
client. Get local client's team before the loop so all bots are
listed.
The lightning trail is fired from the real non-predicted entity for
the local client so it can show the server location. The real client
entity was always used to check if a player entity is firing the
lighting gun. This potentially causes corpses and players on single
player podiums with lightning gun to render the lightning trail if
the real (living) client is firing the lightning gun.
I'm not aware of this causing any issues without modifying the game
logic. Corpses have no weapon and it's not possible to fire during
single player intermission.
GL_CLAMP (clamp to border) was changed to GL_CLAMP_TO_EDGE in 2008
(f2baf359). In 2018 (ce1d5406) I made OpenGL 1.2 be required since
GL_CLAMP_TO_EDGE is used.
Restore support for GL_CLAMP in order to support OpenGL 1.1 like vanilla
Quake 3 does. This should allow using the default Microsoft Windows
GDI Generic OpenGL 1.1 driver (untested but it won't fail the version
check at least).
From gpuinfo.org, it looks like drivers stopped advertising support for
GL_SGIS_texture_edge_clamp so use a version check in addition to the
extension check.
r_allowExtensions 0 disables using GL_CLAMP_TO_EDGE in the opengl1
renderer. GL_CLAMP support wasn't added to the opengl2 renderer.
For lerped frames (refEntity_t frame not equal oldframe) IQM joint
matrices may have incorrect axis scale. This can cause significant model
distortion. The matrix lerp is linear causing each vector to move in a
straight line between frames instead of arcing like a circle. Each joint
frame can have a different scale so can't just normalize the joint
matrix.
Store joints as quaternions and spherical lerp between them and then
convert to a matrix. For my test model, setting up the skeleton is four
times slower now but it still seems to be fast enough to be usable.
r_cubeMapping requires textureCubeLod() which is only in OpenGL 3.0
(GLSL 1.30) and later. It's not in OpenGL ES 3.0 / GLSL ES 3.00.
This needs to be checked before R_InitImages() so can't just check in
GLSL_InitGPUShaders().
Override the video mode list in the Team Arena data files with detected
modes from SDL like in ioquake3's Q3 UI. Add the aspect ratio to the
end of the video resolution (i.e., "640x480 (4:3)"). Add the current
(custom) video mode to the list.
Before when using a custom resolution in the menu you could not change
the video mode using the mouse because the resolution text was blank.
Now custom video resolution is displayed and can be clicked.
Team Arena HUD's team member info box can be cycled through using
nextTeamMember and prevTeamMember commands. nextTeamMember command loops
around when end of list is reached but prevTeamMember command got stuck
at last entry in list (team overview).
My commit last month "Fix SDL audio playback with surround sound" broke
16-bit stereo sound. S_TransferStereo16() still assumed that dma.samples
was a power of two. I also cleaned up code related to the previously
mentioned commit.
If user has surround sound enabled, ioq3 would not play any sound.
Fix painting sound buffer for 4/5.1 audio channels. Extra channels
currently play no audio.
BotSetEntityNumForGoal() was checking all entities that are not
team_redobelisk (which is the obelisk visual entity) to find the
untitled obelisk collision entity. This may fail in rare cases where
there is an another entity within 10 units of the obelisk origin.
Failing to find the correct entity may cause bots to not attack the
obelisk.
Instead add BotSetEntityNumForGoalWithActivator() for looking for the
obelisk collision entity by activator classname (team_redobelisk) which
should be less likely to find the wrong entity.
This doesn't affect official Team Arena maps (unknown if it affects any
others).
Reversed strcmp check was reported by Thomas Köppe.
Bounds are optional for animated IQM models but are not possible to
include with unanimated models (seems intended for use with separate
model containing animations and bounds). Calculating bounds for
unanimated IQM models fixes culling and head model on HUD which
calculates position from model bounds.
The axis returned for IQM tag was the animation's joint rotation without
the base frame joint rotation. It only worked correct for models that
did not rotate the base frame joints.
Using GPU vertex skinning is significantly faster than CPU vertex
skinning. Especially since OpenGL2 has to run R_VaoPackNormal() and
R_VaoPackTangent() each vertex each frame which causes CPU vertex
skinning to be significantly slower than OpenGL1 renderer.
Only calculate vertex blend matrix for each unique bone indexes/weights
combination once per-surface instead of recalculating for each vertex.
For best performance the model surfaces needs to use few vertex bone
indexes and weights combinations.
Unroll loops so GCC better optimizes them.
In my tests drawing animated IQM may take 50% as long in opengl1 and
70% as long in opengl2. It will vary by model though and might not
help much at all.
Made unanimated IQM models skip matrix math altogether.
- Only allocate memory for vertex arrays that are present in the IQM
file and are actually used (may not have colors or blend index/weights,
don't load tangents in opengl1). (Colors is fixed to next commit.)
- Explicitly handle loading IQM files without meshes (bones only).
- Better IQM validation. Header data offset 0 mean data is not present
in file. Check if required vertex arrays are present.
This involved a lot of white space changes and moving code around.
