Documentation

See the documentation for players.

Running a server

Generally, the OpenArena documentation on how to run a server applies. Check out additional settings in ratmod using \cvarlist g_* from the server console.

Some important/recommended settings are (incomplete list):

set sv_pure 1 // pure server, only allow clients to load pk3s also loaded on the server
set sv_fps 40 // ratmod is intended to be used with 40 server frames per second.
set pmove_float 1 // floating-point physics
set pmove_fixed 0

// sv_floodprotect may cause issues (chats not going through etc)
// you should use the g_flood* settings to limit flooding instead
set sv_floodProtect 0 

// enable hitscan delag
set g_delagHitscan 1
set g_lagLightning 0

// recommended:
set sv_timeout 60 // quick timeout
set sv_maxping 0 // may cause problems if set to any other value
set com_ansiColor 1 // colored console
set videoflags 0 // allow clients to use things like vertex light, picmip etc

Many of the mod settings listed are defaults already, but may have different defaults in OA itself. Be careful not to mix up configs from different games.

Download

Ratmod releases are built automatically by Github Actions. The latest releases of the mod be downloaded from github.com.

Installation

Simply put the z-ratmod-v*.pk3 file into ~/.openarena/rat (or %APPDATA%\OpenArena\rat on Windows) and you should be able to load the mod from the OA main menu. You can also launch directly into the mod with openarena +set fs_game rat from the command line (or adjust your desktop shortcut accordingly).

Building

If you want to build ratmod from source, you should check out the ratarena_release repository, which can be used to compile the gamecode and assets in a reproducible manner.

Note: Building Ratmod is only tested on Linux. It might work on BSDs, but will likely fail on Windows.

For developers, you can build the QVM + native code from this repository using:

make WITH_MULTITOURNAMENT=1 BUILD_GAME_QVM=1 BUILD_STANDALONE=1 BUILD_GAME_SO=1 BUILD_MISSIONPACK=0
