Re: Formula for Damping f times

I'd say that you have to aim for 100% repeatable with a physics model
that is meant to be part of a network game, but for non multiplayer
games you could get away with it. However, what do you benefit from
variable time step apart from reduced CPU time on tasks? Not much I'd
say. What you gain from fixed time step, fixed point math, or at least
repeatable math, is the ability to debug your model.

Just because the world is full of people that think just like you,
doesn't mean the other ones can't be right.
