collision question

The easiest way I've found is to expand the sides of the box by the radius of the sphere. You can then just check if the point (the center of the sphere) is inside the 'new' box.

Hope this helps!

fins closest point on the perimeter of the box to the sphere centre. check if that point is in the sphere. YOu also can use that point to push the sphere away from the box so it stops intersecting.

There was a thread with some code and discussion of this algorithm recently in the math and physics forum. Try searching for 'Avro's algorithm' to find it.
