The port is +available as a [patch](/patches/ouroboros-ioq3.patch). The servers +currently only work in dedicated mode (there is no way yet to start a +server from the client). + +To get the demo, first get the latest ioq3 sources: + +``` +$ git clone https://github.com/ioquake/ioq3.git +$ cd ioq3 +``` + +Copy the patch via the link above, or get it via wget: + +``` +$ wget https://ouroboros.rocks/patches/ouroboros-ioq3.patch +``` + +Apply the patch to the ioq3 code: + +``` +$ git apply ouroboros-ioq3.patch +``` + +With Ouroboros installed, build the ioq3 project in standalone mode: + +``` +$ STANDALONE=1 make +``` + +You may need to install some dependencies like SDL2, see the [ioq3 +documentation](http://wiki.ioquake3.org/Building_ioquake3). + +The ioq3 project only supplies the game engine. To play Quake III Arena, +you need the original game files and a valid key. Various open source +games make use of the engine. We wil detail the procedure for running +OpenArena in your ioq3 build directory. + +Go to your build directory: + +``` +$ cd build/<release_dir>/ +``` + +To run OpenArena, you only need to the game files. First download the +zip archive (openarena-0.8.8.zip) from the [OpenArena +website](http://www.openarena.ws) (or via wget) and then extract the +baseoa folder: + +``` +$ wget http://www.openarena.ws/request.php?4 -O openarena-0.8.8.zip +$ unzip -j openarena-0.8.8.zip 'openarena-0.8.8/baseoa/*' -d +./baseoa +``` + +Make sure you have a local Ouroboros layer running in your system (see +[this](/tutorial-1/). + +To test the game, start a server (replace <arch> with the correct +architecture extension for your machine, eg x86_64): + +``` +$ ./ioq3ded.<arch> +set com_basegame baseoa +map aggressor +``` + +Bind the pid of the server to a name and register it in the local layer: + +``` +$ irm bind proc <pid> name my.ioq3.server +$ irm reg name my.ioq3.server layer <your_local_layer> +``` + +To connect, start a client (in a different terminal): + +``` +$ ./ioquake3.<arch> +set com_basegame baseoa +``` + +When the client starts, go to the console by typing ~ (tilde) and enter +the following command + +``` +connect -O my.ioq3.server +``` + +The client should now connect to the ioq3 dedicated server over +Ouroboros. Register the name in non-local layers to connect from other +machines. Happy Fragging! |
