I posted here because this isn't really anything that I'm trying to showcase. I simply wanted to demonstrate physics and physics related issues that I've been having (collision).
The ball does demonstrate nice physics for so easily programmed. The ball is moved solely using the phent_addcentralforce command once per frame, so it's nothing fancy. I have been impressed for the most part with the physics engine. However, I still want to try to help show problems that I am having as to (hopefully) help towards their being improved. I assume if I am having particular problems that others probably are having them as well.
