q3lite's Issues

Compile Error

Getting error at the compile step, it might be an error on my end, but I’m getting this:

Can't connect to server

Just getting "Awaiting Challenge..." when trying to the server.

Mirrors are black

Whenever there should be a mirror i see a black surface instead.

Logging out after quitting game

Hello

I'm really impressed of the performance of q3lite. But I have one issue, why is the game always logging out after quitting the game. I'm starting the game in the console. How can I fix this issue?

Thanks

Portals and mirrors

Any idea why the portals and mirrors have HOM effect on GLES1? Testing on Android devices. Looking to fix myself but just checking if you a hint as to the reason? Thanks!

Build error when we compile with USE_MUMBLE=1 (default)

On latest commit from dev branch there is an error in : code/client/cl_main.c +1409 if the USE_MUMBLE is defined there are misplaced parenthesis which will result in a compilation error.

Building on Mali platform

Hi,
I have an armv8 board (same CPU as the RPi3) with a Mali GPU.
SDL2 (2.0.8) is built and working with GLES2 in framebuffer, for various emulators.
As this isn't Broadcom I've got libEGL.so, libGLESv1_CM.so and libGLESv2.so to build against.

I still have my old PC copy of Q3A I'm very curious to see if I can get this port running.

Questions:

1. I seem to have 2 client builds, both of which I've tried. At runtime I'm getting:

./quake3_opengl2.aarch64

Compiled with SDL v2.0.8
Linking against SDL v2.0.8
----- Client Initialization Complete -----
----- R_Init -----
SDL using driver "mali"
Initializing OpenGL display
Display aspect: 1.778
...setting mode -2: 1920 1080
Trying to get an OpenGL 3.2 core context
SDL_GL_CreateContext failed: Could not create EGL context (call to eglCreateContext failed, reporting an error of EGL_BAD_ATTRIBUTE)
Reverting to default context
----- Client Shutdown (Client fatal crashed: Unsupported OpenGL Version: OpenGL ES 2.0

or with

./quake3.aarch64

Compiled with SDL v2.0.8
Linking against SDL v2.0.8
----- Client Initialization Complete -----
----- R_Init -----
SDL using driver "mali"
Initializing OpenGL display
Display aspect: 1.778
...setting mode 3: 640 480
----- Client Shutdown (Client fatal crashed: Unsupported OpenGL Version: OpenGL ES 2.0

Which is the intended binary?

2. The wiki states "Q3lite is currently compatible with SDL2-2.0.4 only. Newer versions of SDL2 will have subtle issues due to incompatibilities with the Q3lite OpenGL ES 1.1 renderer."
   That's fine, I can build an older version of SDL2 (I've been building it since 2.0.2!), but does this mean it's only supporting GLES1.1 and not GLES2? I thought I'd give it a try as there seemed to be a build option for it in make-raspberrypi.sh which I borrowed as BUILD_RENDERER_OPENGL2=1

3. Should I be using the includes I built SDL2 with, or the ones you've supplied under core/SDL2/inlcudes?

Many thanks for any advice.

smoking guns game

Hello great engine

im trying to run smokinguns game that uses the same engine in a Raspberry pi 3
while im succeded into trying the quake3 rally game
in smoking guns it stucks in the Loading now screen although it loads ok plays videos etc
but when i go to the single player and select any level and press load it stucks in the loading now screen if a press any buttons it goes back to main menu

i have the game running with ./quake3.armv7l +set fs_game smokinguns

the gpu shared mem is 192mb

any suggenstion?

Q3lite compatible with Pi Zero 2 W running Raspberry Pi OS Buster

Hi @cdev-tux.
I just want to confirm, that Q3lite is still compatible with Pi Zero 2 W running Raspberry Pi OS based on Debian Buster.

Since Zero 2 W is really just a under-clocked Pi 3 in Zero size and Buster based OS still works on it, I gave it a go, and with small addition to install script, it compiled and run without any issue.

"^Revision\s*:\s*[ 123][0-9a-f][0-9a-f][0-9a-f]12[0-9a-f]$"

I'm getting 89 fps in FullHD with included timedemo four.

Unable to determine platform type from /proc/cpuinfo

I just ran ./make-raspberrypi.sh but it gave me this

Hello there im trying to use your engine on a raspberry pi3 to play the urban terror

Are there specific instructions/commands to run a mod/standalone game with q3lite?

i tried to launch the game from latest raspbian lite with this command ./quake3.armv7l +set com_hunkMegs 320 +set fs_game q3ut4 (where the q3ut4 folder is the urban terror v4 game)
it worked i loaded the first map but i had artifacts on screen and the mouse was not working correct the whole game was not responding.
are there any extra commands to add to the /quake3.armv7l to make it work correct>?
i compiled the game engine following the normal instructions here
Thanks

Can't not type words at 'Talk' funsion

Hello.
Thanks for your project. I am using raspberry pi 3 for this game and so nice!

But however, I could not type something at the funsion --> talk, when I tick 'T' at my keyboard, and I see a 'say: ' on the screen. But I cannot talk everything,
Please fix.
Thanks again.

q3a-server guide

Hi,

Great work guys. I love seeing these types of projects for the RasPi.

I previously published a quick guide for setting up a Q3A server. It is well suited for the RasPi and other low-power systems. Perhaps you would be interested in adding a link to the repo or using the config files for your own project?

Cheers!

Servers

I was wondering is q3lite clients and servers compatible with regular q3 clients?

Another Map Editor

Noticed that you only have GtkRadiant linked. Should link Quark too: http://quark.sourceforge.net/

Compiling fails under Raspberry Pi OS Bullseye

I used this tutorial https://pimylifeup.com/raspberry-pi-quake-3/

• Under Buster Lite it succeeds.
• Under Bullseye Lite it fails:

Unsupported OpenGL Version (OpenGL ES 2.0), OpenGL 1.2 is required

I'm trying to crosscompile q3lite from an x86 machine to arm, using buildroot (which is an embedded linux system development suite).

I'm calling make directly (not using make-raspberrypi.sh):
q3lite-build.txt

But q3lite isn't starting:
q3lite-glesissue.txt

Throwing the message:
"Unsupported OpenGL Version (OpenGL ES 2.0), OpenGL 1.2 is required"

Would you mind taking a look to see if I'm missing something?

Raspberry pi 4 support

Hello will you add support for the Raspberry pi 4 ??
Thanks

2D objects invisible when VC4 driver used on Raspberry Pi

The VC4 driver for Raspberry Pi allows use of Mesa instead of Broadcom-specific GL APIs.

Firstly, Q3lite runs normally and as expected with the default Broadcom GL libraries. But I wanted to run Q3lite with the VC4 driver, so I did this by first configuring my system to use VC4, then modifying the Makefile like so:

diff --git a/Makefile.q3lite b/Makefile.q3lite
index bd7929a..4101d0c 100644
--- a/Makefile.q3lite
+++ b/Makefile.q3lite
@@ -140,15 +140,16 @@ endif
     PI_CFLAGS=-march=armv8-a+crc -mfpu=vfpv4 -mtune=cortex-a53
   endif
   CFLAGS += -DHAVE_GLES $(PI_CFLAGS) -mfloat-abi=hard -Ofast -I/opt/vc/include
-  ifneq ($(wildcard /opt/vc/lib/libbrcmEGL.so),)
-    ifneq ($(wildcard /opt/vc/lib/libbrcmGLESv2.so),)
-      LDFLAGS += -L/opt/vc/lib -lbrcmEGL -lbrcmGLESv2
-    else
-      LDFLAGS += -L/opt/vc/lib -lEGL -lGLESv2
-    endif
-  else
-    LDFLAGS += -L/opt/vc/lib -lEGL -lGLESv2
-  endif
+  LDFLAGS += -lEGL -lGLESv2 -lGL
 
 endif #ifneq ($(PLATFORM_TYPE),)

Exactly how correct this approach was I'm unsure (having no GL experience whatsoever) but it at least compiled.

I ran it within an X11 session with the following parameters:

./quake3.armv7l \
  +set com_hunkMegs 192 \
  +set com_zoneMegs 24 \
  +set com_soundMegs 16 \
  +set vm_ui 2 \
  +set vm_cgame 2 \
  +set com_introplayed 1 \
  +set com_protocol 68 \
  +map q3dm1 \
  +set r_mode -1 \
  +set r_customwidth 1024 \
  +set r_customheight 768 \
  +set r_fullscreen 0

The game started, and I could see the map and walk around, but all 2D things were missing from the display, like my crosshair, health status, and the pull-down console.

I ran the game through apitrace and noticed the following errors:

99138: message: major api error 1: GL_INVALID_OPERATION in unsupported function called (unsupported extension or deprecated function?)
99138 @0 glOrthof(left = 0, right = 1920, bottom = 1080, top = 0, zNear = 0, zFar = 1)
99138: warning: glGetError(glOrthof) = GL_INVALID_OPERATION

According to the documentation, it appears the glOrthof() function doesn't exist in OpenGL ES 2.0, and hence not Mesa, but for some reason is included in the Broadcom ES 2.0 library anyway:

grep --files-with-matches glOrthof /opt/vc/lib/libbrcmGLESv2.so /lib/libGLESv2.so
/opt/vc/lib/libbrcmGLESv2.so

grep --files-without-match glOrthof /opt/vc/lib/libbrcmGLESv2.so /lib/libGLESv2.so
/lib/libGLESv2.so

I've attached the apitrace file. I'm not sure how portable this file is, but it reproduces the graphical issue nicely on my laptop with Intel graphics:

quake3.invisible.trace.gz

As VC4 is the long-term future of graphics on the Raspberry Pi, using more standard components of the Linux graphics stack (Mesa, DRM, KMS), it will be good to get Q3lite working in this situation.

not an issue.. but a thankyou!

managed to get this compiling on ubuntu 16.04 with the 3.4 downstream kernel on the Microsoft Surface RT 1 and 2 (arm32). runs great and uses the nvidia gles driver for full gpu acceleration.

thank you for making this port!
