Hi all, i'm moving my objects according to when the last frame was rendered.

I want things to move every 10ms, but on slow computers this won't happen, and on fast computers i want think to move as smoothly as possible.

I'm currently moving objects using this as a way of altering there velocity according to the time passed:

Code:
x*(GetTickCount()-LastThink)/10
where x is the actual velocity, and lastthink is the last time the object moved (the 10 is because i want things based on 10ms).

I think this works ok, but i'm having trouble with acceleration. I'm currently doing this to gradually reduce the speed of my object:
Code:
Velocity *= 0.98
This doesn't work, the object slows down faster when i'm on a fast computer (and it's called a lot), but takes ages to slow down on a slow computer (when it's not called as often).

To fix this i tried using this (pow is a funciton calculating is 1st parameter raised to the power of its 2nd parameter.):
Code:
velocity *= pow(0.98f,(float)((GetTickCount()-LastThink)/10))
This doesn't work either unfortunatly.


Anyone have any ideas??
