Hey

Lets say I'm making an animation with a ball kicking about in a box -
obviously the ball needs to bounce off the box which is ok if I know the
dimensions of the box. But lets suppose I don't. So how do I achieve
collision detection?

I have a feeling that the answer lies in the trace() function but after
reading and re-reading the docs I still don't understand the concept. Is
there any tutorials anywhere for this sort of thing?

Thanks
jim
