Taking it out on you? Why the hell do people always feel they are being attacked when I try to explain reality.
The reality is, such a physics are quite hard to create in darkplaces and quakec. I agree that these physics would improve the game, I don't think anyone would argue against that but we need to find a line between fantasy and reality.
I found Urre's post inspiring. Far beyond my current capabilities but perhaps some of the more inclined mathematicians will find pleasure in the article. Maybe even build off the source.
I'm not trying to discourage anyone, I'm trying to inform you of the facts.
