Help needed!

We encourage researchers and students in the area of real-time AI to take a look at ORTS and to consider it as a test-bed for their research.

We are also inviting game designers, computer graphics artists, and graphics programmers to contribute to the project by creating new races, low-poly unit and structure models, ground textures, GUI widgets, and stunning particle effects (example).

ORTS development is under full steam!

Plans for Summer 2007 are:


System Requirements

For the graphics client (ortsg) under Linux to reach frame rates >= 20 fps, currently you'll need a mid-range NVIDIA graphics card because the Linux ATI drivers are poor (as of mid 2005). Under Windows there is no such restriction. Having at least 128 MB of video RAM helps and 512 MB of system RAM is minimum when using ortsg.

Download and Installation

Daily development snapshot

SVN Access

(July 2010: the svn URL has changed!)

svn co svn://[user-id]@skatgame.net:/all/pubsoft/orts
svn co svn://[user-id]@skatgame.net:/all/pubsoft/orts_data
(anonymous read-only access: user-id=anonymous password=guest)

See orts/trunk/README for compilation instructions. ORTS compiles under Linux (Fedora 13), MS VC++8, and (probably) MacOS. You need the Boost library, SDL, SDL_net, zlib, OpenGL, glew, and freeglut to compile ORTS.

Compiling ORTS on Windows with VC++8

Follow the instructions in orts\trunk\misc\windows\howto after downloading this archive: win32.zip.
Feedback welcome! We need developers who use VC++ to test and improve the VC++ setup. We recently added a tool that creates project files automatically.
