Sauerbraten

Documentation

Sauerbraten is multiplayer/singleplayer FPS freeware game project, and soon an RPG game project. The sourcecode for the engine used in these games is Open Source (ZLIB licence, read the "License" section below carefully before starting ANY kind of project based on this engine).

You will want to read (roughly this order):

• Game: Information on gameplay.
• Config: How to run the game, configure it for your machine, and extend it with scripts.
• Editing Tutorial: A guide to making maps.
• Editing Reference: Map making reference.
• Models: How to put models into the game.
• History: For seeing latest changes.
• RPG: Some notes on the in-development RPG, Eisenstern.

The Wiki

In addition to the documentation provided, the wiki has a lot of useful information for working with the game and engine, contributed by the community which elaborates and breaks alot of the information down into more digestable chunks. This is just provided a short rundown of the most useful topics to new players, and those looking for quick readable information. For more go visit the Cube Wiki Online, or use the Offline Version.

• Beginners Guide: Go through the steps to get up and running (offline version).
• Frequently Asked Questions: Get the answers to some commonly asked questions, like; "The game runs very slowly, how can I fix it?", "Why is the game behaving strangely?", and "How do I fix the 'Hall of Mirrors' effect?" (offline version).
• Performance Guide: Things you can try to make Sauerbraten either run faster or look better on your machine (offline version).
• Older Stuff: From Quadropolis.
• Some old random documentation bits from our previous wiki that don't have a place yet.

Current Features

Sauerbraten is under constant development, but is very feature-rich and playable as a game. What follows is a list of the most prominent features.

Game Features

• Oldskool fast & intense gameplay (read: similar to Doom 2 / Quake 1).
• Many multiplayer gameplay modes, most in teamplay variants as well: deathmatch, instagib, efficiency, tactics, capture (domination/battlefield style), coop edit (!).
• Masterserver & ingame server browser.
• Lag-free gameplay experience.
• Two singleplayer modes: DMSP (fight a monster invasion on any DM map), classic SP (progression driven SP like other games)
• 7 weapons tuned for maximum satisfaction: double barrelled shogun, rocket launcher, machine gun, rifle, grenade launcher, pistol, fist.

Engine Features

• 6 directional heightfield in octree world structure allowing for instant easy in-game geometry editing (even in multiplayer, coop edit).
• Rendering engine optimized for high geometry throughput, supporting hardware occlusion culling.
• Lightmap based lighting with accurate shadows from everything including mapmodels, smooth lighting for faceted geometry, and fast compiles.
• Pixel and vertex shader support, each model and world texture can have its own shader assigned.
• Robust physics written specifically for this world structure.
• Loading of md2/md3 models for animated characters, weapons, items, world objects.
• Network library designed for high speed games, client/server network system.
• Small but complete configuration/scripting language.
• Simple stereo positional sound system.
• Particle engine, supporting text particles.
• 3d menu/gui system, for in-world representation of choices.

License

The Sauerbraten game is freeware, you may freely distribute the Sauerbraten archive/installer unmodified on any media. You may re-compress using different archival formats suitable for your OS (i.e. zip/tgz/rpm/deb/dmg), any changes beyond that require my explicit permission.

You may play Sauerbraten for any purpose as long as you don't blame the authors for any damages incurred.

If you want to produce new content with the sauerbraten engine, you have to be aware that the source code may be Open Source, but the game and the media it consist of have their individual licenses and copyrights. This means that you have roughly 3 options:

• You may produce new content for the sauerbraten game, for example as a "custom map" (.ogz/.cfg/textures etc). Contributing to the original game is most welcome, and the most productive way of working with Sauerbraten.
• If you want to create your own gameplay beyond what you can do with a map, the best way to do this is as a "mod" (same as above, but with new executable that incorporates your gameplay), that requires an existing install of sauerbraten, and installs only the new files you created in parallel to the existing files.
• If you insist on making a standalone game based on sauerbraten, do realize that only the sourcecode is yours to use freely (if you abide by the ZLIB license, see below), not the media. You CANNOT simply redistribute the entire sauerbraten package with your modified files, as the majority of game media is not yours to use freely (it is made by many authors with a variety of licences and copyright restrictions). Unless you have explicit permission from the authors, or the readme says explicitly "may be used for any purpose" or similar language, it will be illegal to include in your standalone game based on the sauerbraten engine (you may not assume that just because a file has no explicit license, that it is free of copyright). Therefore, if you wish to produce a standalone game, be prepared to make many of the maps, models, textures, sounds etc from scratch yourself.

In this sense sauerbraten is similar to games like Quake (its code is Open Source, but its media is not), it is a game that is meant to be added to, not copied and used as a template. Sauerbraten is not meant to be a quick game creation kit, it is a game.

If you wish to use the Sauerbraten source code (ZLIB license) in any way, read the src/readme_source.txt file carefully.
