Is there any built librarys/function for collision detection?

We provide a number of bounding volumes with intersection and containment checks. This would give you simple collision detection.

We do not provide any sort of complex collision detection or physics simulation (collision or response).

Paul,

Are you with Microsoft? If so, can you explain why complex collision detection was left out of the XNA Framework since it was available in Managed DirectX 2.0 using the Mesh.Intersect method? Complex collision detection is a must if you want to do things like fire a bullet at an object and have the bullet leave a mark on the object. Is this something that will be added to the XNA Framework in the future? Even if you want to use the Bounding Box based model collision detection in the XNA Framework, you have to determine the Bounding Box or Bounding Sphere yourself when under MDX 2.0 there is a Geometry class that could compute these things for you. I thought XNA was supposed to make things easier not more difficult.

I would appreciate any comments from Microsoft on this.
