The use of signed types in these expressions lead to overflow, hence undefined behaviour. The "sum" aggregator in Com_TouchMemory isn't even used (and presumbably just exists to inhibit optimizations from removing the memory access).
SDL_CFLAGS and SDL_LIBS assignment was "only if absent". However due
to previously assigning them to "pkg-config sdl2" values, the values
from sdl2-config were ignored.
- Parse OpenGL version in sdl_glimp.c to share with both renderers.
- Add GL_VERSION_ATLEAST(major, minor) macro.
- Get address of glGetStringi if using OpenGL 3.
- Fix glConfig.extensions_string when using GL3 core context in
opengl2 renderer.
- Make opengl1 renderer's gfxinfo support qglGetStringi too.
Get all OpenGL functions using SDL_GL_GetProcAddress(). This makes it
easier to cross-arch compile on Linux and add support for OpenGL ES
in the future.
Users still have to supply their own libSDL2 for cross-arch compiling
on Linux. But now the user does not have to re-install libgl1-mesa-dev
package for i386 or amd64 on Debian when switching between compiling
ioquake3 for x86 and x86_64.
If a lightning bolt killed a player or the first shotgun pellet that
hit a player killed them, the shot was not counted as accurate.
Check if shot player is alive for hit accuracy before dealing damage.
Fix for ioq3 test builds for Windows x86 (cross-compiled from Ubuntu
using mingw-w64) requiring libgcc_s_sjlj-1.dll. I'm unable to reproduce
the issue using mingw-w64 in Debian or Cygwin.
Vanilla Q3 UI doesn't list multiple master servers. ioquake3 changed
globalservers 0 to be all masters so they show in Q3 UI, moving single
masters from 0-4 to 1-5.
Vanilla Elite Force on the other hand, uses 0-4 for separate master
servers. So restore that behavior.
Running a server using the client engine would send server snapshots
to loopback and LAN clients each client frame (com_maxfps).
This causes excessive network traffic and likely does not provide new
information to the clients because SV_Frame() won't have run between
the extra snapshots.
This commit restores the original behavior of respecting local/LAN
client's snaps userinfo and sv_fps. The issue was introduced by the
following commit:
Commit ac30d86db0
From: Thilo Schulz
Date: Wed, 13 Jul 2011 17:11:30 +0000
Subject: - Improve snapshot rate and data rate control
Reported by Eugene C.
Fix "Error parsing animation file" messages in UI. Caused by fixing the
handling of missing tokens in animation.cfg parser in a past commit.
Fix new Team Arena torso animation frame numbers in UI.
Add support for fixedtorso and fixedlegs keywords.
Add support for reversed animations (negative numframes).
Disable SDL relative mouse mode when in_nograb is enabled. Relative
mouse mode hides the cursor and it cannot exit the window regardless
of the window's grab state.
This wasn't always the case. SDL before 2.0.4 on GNU/Linux released
the mouse cursor in relative mode. However, SDL 2.0.3/4 on Windows
does not. (I did not test other Windows versions.) So I think SDL
2.0.4 made GNU/Linux X11 behavior consistent with other platforms.
This fixes mouse input being unusable when debuging client crashes
in gdb.
Entering Team Arena's start server or in-game callvote menu causes
arenas to be reloaded. The existing memory is not freed so after
a entering the menus a few times the UI runs out of memory and
crashes.
Just load arenas once when the UI loads like in q3_ui.
- Use common controls 6 so error dialogs use correct visuals on
Windows XP or later!
- Specify running as invoker so Windows doesn't guess if it should
prompt for admin permission on Vista or later.
- Specify compatible with Vista through Windows 10. Tells Windows
not to emulate Vista behavior, not sure if it affects anything.
Makefile automatically runs windres when manifest changes.
After 'Fix floating point precision loss in renderer', Windows x86
client won't load the renderer DLLs. The problem is a 64 bit modulus.
I couldn't find any reports of this online. However, client with
built-in renderer worked with the 64 bit modulus.
Only tested with mingw-w64.
ioquake3.x86_64.exe can't load x86 OpenAL32.dll. Using separate
library names allows shipping OpenAL for both architectures.
Though since the dll name is saved in the config file, using both
clients on the same computer will cause one client arch to always
try to load the wrong OpenAL dll and then fallback to the correct
default OpenAL dll. I guess it could be fixed by using separate
cvar names for s_alDriver.
Don't draw crosshair 0 in Team Arena setup menu. It isn't drawn
in CGame. Wrap cg_drawCrosshair in missionpack menu like CGame
instead of treating as index 0 which is no longer drawn.
Make spectators use green background for team chat box when following
players. The team chat messages are from spectators not the team of
the followed player.
Make spectators draw team chat box even when not following a player.
Only use the crusher for killing the bot's enemy. This doesn't
affect 1v1 very much but prevents the whole team of bots in CTF
from suddenly shooting at the crusher button. Entering the crusher
bounds was basically instant death.
Make bots activate crusher on q3tourney6_ctf and mpq3tourney6.
Check if player is inside the crush bounds instead of below the
crusher. There is a jumppad the goes under it in mpq3tourney6.
SDL doesn't provide exact the exact time that input events happen
so use the earliest possible time that an event could happen.
This make sub-frame input actions such as walking take affect
immediately instead of in the next frame.
Based on patch by Alexander "wareya" Nadeau.
Make callTeamVote check for all command separators like in callVote.
It's not exploitable as the only vote option (leader) always uses an
integer argument.
Also the ioquake3 engine remove command separators from client game
commands in Cmd_Args_Sanitize().
