This is a partial port of the bullet physics library (v2.79) , written in C# and using the XNA 4.0 libraries. It's aim as much as possible was to provide a fairly straight port of the c++ libraries to make maintaining compatability between the 2 version easier.

Current stable version is : 127

It currently supports:

All collision shapes All constraint types It doesn't support :

Bullet Serialization Soft Body It supports :

pc,360 and windows phone 7.1. Links / Examples

Ragdoll Demo / Contraints - twitchy BvhBroadphase? - seems to be a bug in cleanup , removing then adding all items breaks collision - noticed in KillerCore? To Do

2.82 updates where appropriate. Mult-threading support (see multi-threaded branch) MonoGame? support Remove dependencies on 'core' xna where possible to move to a more platform netural library Add serialisation Further performance improvements Most widely used internal objects are now pooled. Most chokepoints now have in-lined code. New demos Soft Body if I'm feeling brave. Playstation Suite? ;) Many thanks to the JetBrains? team for the use of their excellent dotTrace profiling tools that have helped tremendously on this port.
