Raymond's comment about not being able to find the collision code is a bit absurd. I can't recall if Danny or I named the top-level collision detection function, but it was just named 'pb_collide'.

It's nice to be able to point to this line: https://github.com/k4zmu2a/SpaceCadetPinball/blob/5947727f80...

And, while it is true that the code is sparsely commented, the geometry code that computes ray intersections is commented.
