Q3lite is an updated id Tech 3 game engine for embedded Linux systems. The project is a fork of ioquake3. Q3lite provides users with an updated version of the engine running on OpenGL ES and SDL2. The goal of the project is to add useful new features that enhance the game experience for both players and server administrators while staying in sync with the updated Quake III Arena engine. The long term plan is to slim the code down to improve performance on low-end embedded processors, hence the name Q3lite.
- Raspberry Pi Zero, Zero W
- Raspberry Pi 1 Model A+, B, B+ w/512 MB Memory
- Raspberry Pi 2
- Raspberry Pi 3, 3A+, 3B+
- Pi platforms are supported on Raspbian Desktop and Raspbian Lite
- Built on the latest ioq3 codebase using OpenGL ES.
- Set the game resolution independent of your desktop resolution on the Pi.
- Play full screen with or without x11 running.
- Optimized player and dedicated server config files included with instructions for each setting.
- The provided compile script automatically detects the Pi processor type and sets optimized compiler settings.
- Includes a robust installer to automatically create game directories, copy game files and download / install updated pak files from the Q3A Point Release. It can also install SDL2 dynamic libraries so there's no need to compile or preinstall SDL2. The installer creates game, server, rcon and timedemo launch icons in the applications menu as seen in the image above.
Note: You'll still need to copy the pak0.pk3 file from your full version of Quake III Arena to play the game. See section 1.1 of the Q3lite FAQ for details.
- Uninstaller included for removing installation if desired.
- Includes all files and step by step instructions to run a dedicated server from the applications menu or as a systemd service at boot time.
- Timedemo four runs at ~150 fps on a Pi 3 B+ at 720P (without overclocking).
- Also includes a desktop Remote Console (rcon) application to send console commands to the background server.
New Q3lite cvars
These cvars are in addition to those currently available in the base game. All new features can be turned off to maintain default Quake3 behavior. Set client cvars in your autoexec.cfg file and server cvars in your server.cfg file, both located in ~/.q3a/baseq3.
Client cvars: cg_drawSpeedometer <0|1> - Toggle display of player speed in Quake units per second. Speed shown in upper right corner under the match clock. Also works with demos and while following other players in spectator mode. 0 = disabled. 1 = enabled. cg_nochatbeeps <0|1|2|3> - Toggle playing of the chat beep sound. Handy on servers with chatty spectators. 0 = disabled. 1 = No chat beeps for non-team chat only. 2 = No chat beeps for team chat only. 3 = No chat beeps for team / non-team chat. cg_novotebeeps <0|1|2|3> - Toggle playing of the vote beep sound. 0 = disabled. 1 = No vote beeps for non-team votes only. 2 = No vote beeps for team votes only. 3 = No vote beeps for team / non-team votes. cg_noTaunts <0|1> - Toggle playing of client taunt sounds. Useful when opponents press the taunt key excessively. 0 = disabled. 1 = No taunt sounds played. Server cvars: g_intermissionDuration <seconds> - Limits end-of-round intermission duration. Prevents endless intermission if a human player is away from the keyboard. 0 = disabled. > 0 = intermission duration in seconds, then server moves to the next map. Valid range 5 - 30 seconds. sv_inactivity <seconds> - Move player to spectator mode after a period of inactivity rather than kick them as g_inactivity does. Set to a lower value than g_inactivity if both are used. 0 = disabled. > 0 = inactivity period in seconds, then server moves player to spectator mode. sv_maxconcurrent <0|1..64> - Limits the number of simultaneous player connections from the same IP address. 0 = disabled. Valid range 1 - 64.
- See the Compiling and Installation Guide for instructions on how to get Q3lite up and running.
- Copy the pak0.pk3 file from your official copy of Quake III Arena or Steam version to
- Set the memory split on the Pi platform. See section 2.2 of the Q3lite FAQ for details.
- Be sure to set the necessary passwords in your server.cfg file located in ~/.q3a/baseq3.

Compilation and installation
- Change to the directory containing this readme.
- Run 'make'.
- Please refer to the excellent instructions here: http://wiki.ioquake3.org/Building_ioquake3
For Mac OS X, building a Universal Binary
- Install MacOSX SDK packages from XCode. For maximum compatibility, install MacOSX10.4u.sdk and MacOSX10.3.9.sdk, and MacOSX10.2.8.sdk.
- Change to the directory containing this README file.
- Run './make-macosx-ub.sh'
- Copy the resulting ioquake3.app in /build/release-darwin-ub to your /Applications/ioquake3 folder.
Installation, for *nix
- Set the COPYDIR variable in the shell to be where you installed Quake 3 to. By default it will be /usr/local/games/quake3 if you haven't set it. This is the path as used by the original Linux Q3 installer and subsequent point releases.
- Run 'make copyfiles'.
It is also possible to cross compile for Windows under *nix using MinGW. Your distribution may have mingw32 packages available. On debian/Ubuntu, you need to install 'mingw-w64'. Thereafter cross compiling is simply a case running 'PLATFORM=mingw32 ARCH=x86 make' in place of 'make'. ARCH may also be set to x86_64.
The following variables may be set, either on the command line or in Makefile.local:
CFLAGS - use this for custom CFLAGS V - set to show cc command line when building DEFAULT_BASEDIR - extra path to search for baseq3 and such BUILD_SERVER - build the 'ioq3ded' server binary BUILD_CLIENT - build the 'ioquake3' client binary BUILD_BASEGAME - build the 'baseq3' binaries BUILD_MISSIONPACK - build the 'missionpack' binaries BUILD_GAME_SO - build the game shared libraries BUILD_GAME_QVM - build the game qvms BUILD_STANDALONE - build binaries suited for stand-alone games SERVERBIN - rename 'ioq3ded' server binary CLIENTBIN - rename 'ioquake3' client binary USE_RENDERER_DLOPEN - build and use the renderer in a library USE_YACC - use yacc to update code/tools/lcc/lburg/gram.c BASEGAME - rename 'baseq3' BASEGAME_CFLAGS - custom CFLAGS for basegame MISSIONPACK - rename 'missionpack' MISSIONPACK_CFLAGS - custom CFLAGS for missionpack (default '-DMISSIONPACK') USE_OPENAL - use OpenAL where available USE_OPENAL_DLOPEN - link with OpenAL at runtime USE_CURL - use libcurl for http/ftp download support USE_CURL_DLOPEN - link with libcurl at runtime USE_CODEC_VORBIS - enable Ogg Vorbis support USE_CODEC_OPUS - enable Ogg Opus support USE_MUMBLE - enable Mumble support USE_VOIP - enable built-in VoIP support USE_FREETYPE - enable FreeType support for rendering fonts USE_INTERNAL_LIBS - build internal libraries instead of dynamically linking against system libraries; this just sets the default for USE_INTERNAL_ZLIB etc. and USE_LOCAL_HEADERS USE_INTERNAL_ZLIB - build and link against internal zlib USE_INTERNAL_JPEG - build and link against internal JPEG library USE_INTERNAL_OGG - build and link against internal ogg library USE_INTERNAL_OPUS - build and link against internal opus/opusfile libraries USE_LOCAL_HEADERS - use headers local to ioq3 instead of system ones DEBUG_CFLAGS - C compiler flags to use for building debug version COPYDIR - the target installation directory TEMPDIR - specify user defined directory for temp files

README for Developers
ioquake3 has a useful new feature for mappers. Paths in a game directory with the extension ".pk3dir" are treated like pk3 files. This means you can keep all files specific to your map in one directory tree and easily zip this folder for distribution.
If you wish to compile external mods as shared libraries on a 64bit platform, and the mod source is derived from the id Q3 SDK, you will need to modify the interface code a little. Open the files ending in _syscalls.c and change every instance of int to intptr_t in the declaration of the syscall function pointer and the dllEntry function. Also find the vmMain function for each module (usually in cg_main.c g_main.c etc.) and similarly replace the return value in the prototype with intptr_t (arg0, arg1, ...stay int).
Add the following code snippet to q_shared.h:
#ifdef Q3_VM typedef int intptr_t; #else #include <stdint.h> #endif
Note if you simply wish to run mods on a 64bit platform you do not need to recompile anything since by default Q3 uses a virtual machine system.
Creating mods compatible with Q3 1.32b
If you're using this package to create mods for the last official release of Q3, it is necessary to pass the commandline option '-vq3' to your invocation of q3asm. This is because by default q3asm outputs an updated qvm format that is necessary to fix a bug involving the optimizing pass of the x86 vm JIT compiler.
Creating standalone games
Have you finished the daunting task of removing all dependencies on the Q3 game data? You probably now want to give your users the opportunity to play the game without owning a copy of Q3, which consequently means removing cd-key and authentication server checks. In addition to being a straightforward Q3 client, ioquake3 also purports to be a reliable and stable code base on which to base your game project.
However, before you start compiling your own version of ioquake3, you have to ask yourself: Have we changed or will we need to change anything of importance in the engine?
If your answer to this question is "no", it probably makes no sense to build your own binaries. Instead, you can just use the pre-built binaries on the website. Just make sure the game is called with:
+set com_basegame <yournewbase>
in any links/scripts you install for your users to start the game. The binary must not detect any original quake3 game pak files. If this condition is met, the game will set com_standalone to 1 and is then running in stand alone mode.
If you want the engine to use a different directory in your homepath than e.g. "Quake3" on Windows or ".q3a" on Linux, then set a new name at startup by adding
+set com_homepath <homedirname>
to the command line. You can also control which game name to use when talking to the master server:
+set com_gamename <gamename>
So clients requesting a server list will only receive servers that have a matching game name.
+set com_basegame basefoo +set com_homepath .foo +set com_gamename foo
If you really changed parts that would make vanilla ioquake3 incompatible with your mod, we have included another way to conveniently build a stand-alone binary. Just run make with the option BUILD_STANDALONE=1. Don't forget to edit the PRODUCT_NAME and subsequent #defines in qcommon/q_shared.h with information appropriate for your project.
Standalone game licensing
While a lot of work has been put into ioquake3 that you can benefit from free of charge, it does not mean that you have no obligations to fulfill. Please be aware that as soon as you start distributing your game with an engine based on our sources we expect you to fully comply with the requirements as stated in the GPL. That includes making sources and modifications you made to the ioquake3 engine as well as the game-code used to compile the .qvm files for the game logic freely available to everyone. Furthermore, note that the "QIIIA Game Source License" prohibits distribution of mods that are intended to operate on a version of Q3 not sanctioned by id software:
"with this Agreement, ID grants to you the non-exclusive and limited right to distribute copies of the Software ... for operation only with the full version of the software game QUAKE III ARENA"
This means that if you're creating a standalone game, you cannot use said license on any portion of the product. As the only other license this code has been released under is the GPL, this is the only option.
This does NOT mean that you cannot market this game commercially. The GPL does not prohibit commercial exploitation and all assets (e.g. textures, sounds, maps) created by yourself are your property and can be sold like every other game you find in stores.
ioquake3 supports the use of PNG (Portable Network Graphic) images as textures. It should be noted that the use of such images in a map will result in missing placeholder textures where the map is used with the id Quake 3 client or earlier versions of ioquake3.
Recent versions of GtkRadiant and q3map2 support PNG images without modification. However GtkRadiant is not aware that PNG textures are supported by ioquake3. To change this behaviour open the file 'q3.game' in the 'games' directory of the GtkRadiant base directory with an editor and change the line:
texturetypes="tga jpg png"
Restart GtkRadiant and PNG textures are now available.
Building with MinGW for pre Windows XP
IPv6 support requires a header named "wspiapi.h" to abstract away from differences in earlier versions of Windows' IPv6 stack. There is no MinGW equivalent of this header and the Microsoft version is obviously not redistributable, so in its absence we're forced to require Windows XP. However if this header is acquired separately and placed in the qcommon/ directory, this restriction is lifted.
Please send all patches to bugzilla (https://bugzilla.icculus.org), or as a GitHub pull request and submit your patch there.
The focus for ioq3 is to develop a stable base suitable for further development and provide players with the same Quake 3 experience they've had for years.
We do have graphical improvements with the new renderer, but they are off by default. See opengl2-readme.md for more information.
Building Official Installers
We need help getting automated installers on all the platforms that ioquake3 supports. We don't necessarily care about all the installers being identical, but we have some general guidelines:
Please include the id patch pk3s in your installer, which are available from http://ioquake3.org/patch-data/ subject to agreement to the id EULA. Your installer shall also ask the user to agree to this EULA (which is in the /web/include directory for your convenience) and subsequently refuse to continue the installation of the patch pk3s and pak0.pk3 if they do not.
Please don't require pak0.pk3, since not everyone using the engine plans on playing Quake 3 Arena on it. It's fine to (optionally) assist the user in copying the file or tell them how.
It is fine to just install the binaries without requiring id EULA agreement, providing pak0.pk3 and the patch pk3s are not referred to or included in the installer.
Please include at least a libSDL2 so/dylib/dll on every platform.
Please include an OpenAL so/dylib/dll, since every platform should be using it by now.
Please be prepared to alter your installer on the whim of the maintainers.
Your installer will be mirrored to an "official" directory, thus making it a done deal.
