OpenSteer: Steering Behaviors for Autonomous Characters

Feb. 2019

• Ported to glfw and Cmake

OpenSteer is a C++ library for constructing steering behaviors for autonomous characters in games and animation. In addition to the library, OpenSteer provides an OpenGL-based application called OpenSteerDemo which demonstrates a variety of steering behaviors. The user can quickly prototype, visualize, annotate and debug new steering behaviors by writing a plug-in for OpenSteerDemo.

OpenSteer provides a toolkit of steering behaviors, defined in terms of an abstract mobile agent called a "vehicle." Sample code is provided, including a simple vehicle implementation and examples of combining simple steering behaviors to produce more complex behavior. OpenSteer's classes have been designed to flexibly integrate with existing game engines by either layering or inheritance.

OpenSteerDemo's plug-in framework allows a game AI programmer to quickly prototype behaviors during game design, and to develop behaviors before the main game engine is finished. OpenSteerDemo allows the user to interactively adjust aspects of the simulation. The user can: start, stop and single step time, select the vehicle/ character/ agent of interest, adjust the camera's view and its tracking behavior.

OpenSteer was initially developed by Craig Reynolds beginning in 2002 at the Research and Development group of Sony Computer Entertainment America. The OpenSteer authors wish to acknowledge the support of SCEA, SCEI and in particular these executives who had the foresight to release this code as open source for all to use: Shin'ichi Okamoto, Masa Chatani and Dominic Mallinson.

After OpenSteer's source code was first released on May 1, 2003 a group of dedicated volunteers quickly formed and began to extend the system. Ports to Windows and Mac OS X were contributed within 24 hours! Today we continue to discuss, test and improve OpenSteer. To contribute, or to just listen in, please visit the Open Discussion forum.

Here is a partial list of those who have contributed to OpenSteer, sorted roughly by the amount and "freshness" of their contributions: Bjoern Knafla (bknafla), Nick Porcino (meshula), Ben Forsyth (bforsyth), Dominik (inikofdoom), Paul (spanneradmin), Kris Hauser (kkhauser), Leaf Garland (leaf), Stefan Moises (beffy), Bruce Mitchener (brucem), Maciej Sinilo (yarpen), Michael Holm (gizwiz), Richard Cannock (perambulator). Let us know of any omissions from this list.
