Does anyone know of a non-cpu intensive way of measuring a physics objects' angle of motion?
ATM I base the angle on an earlier position and compare it to a current one. However, to get this smooth it is calculating it every 0.01 seconds, and I think this may be pretty intensive.
Say for example I'm trying to 'animate' an arrow so that it launches into the sky and falls down, with the arrow head always leading the way. The thing is, I have to use physics.
