Hmmm I'm not sure why I didn't carry the Explode Behavior over to WPF... I don't think there is anything in there that WPF won't handle, so it should be an easy port. There were some differences with WPF for the Sound Behavior so I remember I couldn't quickly
port that one. Anyway if you want to try porting Explode, you should just need to bring in the PhysicsExplodeBehavior into the PhysicsBehaviors.WPF project, and then create a ucExplode user control that has the explode animation.
As far as documentation, here are the best sources I think:
1. The Videos at http://physicshelper.codeplex.com/
2. The Demos included in the download
3. The documentation for Farseer, as this is the underlying engine in the Helper:
http://farseerphysics.codeplex.com/ ... Note that you can get at any of the Farseer Objects in the Physics Helper, see the section "Coding Techniques" at
