This is a physics engine only release. No new demos.
This release includes the following updates:
Updated PolygonRigidBody, RectangleRigidBody, CircleRigidBody, and PointRigidBody. Rectangle, Circle, and Point rigid bodies now all derive from PolygonRigidBody.
I've also fixed up the constructors so that the collisionPrecisionFactor can be passed in if desired.
Updated all the Joint and Spring code.
RevoluteJoint now derives from the abstract Joint class. LinearSpring and AngularSpring now derive from the abstract Spring class.
All springs and joints now support the Dispose pattern. Calling Dispose on any of these objects will instantly remove there influence within the physics world.
If a body is disposed that is part of a joint or spring, then the corresponding spring or joint will automatically be destroyed.
I started creating a .chm help file. You can currently find it in the bin-->Debug-->Help folder. Not much there yet, but I'll be adding to it continuously.
That's all I can think of... Have fun and post in the forums if you have questions.
