Well I'm starting a new game and it will be the first time using timer based movement. So I looked online to get a basic understanding of it. I came up with this simple code for it but can someone tell me if I've done it properly?
Here, timer damping is the amount to multiply the sprite movements by. Do I have to call up GetTimerDamping every time I position a sprite or just once at the top of my loop?

The way I do it is like this:



Where t and factor# must be global, I then multiply my movement code by factor.



will move the object at 10unit/sec

Your method looks similar, I can't see why it wouldn't work, just remember to make tmr global

Ok good, just checking, and Tmr is global.
Your's is pretty much the same except t is updated right after the factor# is taken. Does that make a difference? When am I actually supposed to update Tmr.LastF, before the sync, after it, or at the beginning of my loop?

Nah it won't matter at all, neither does the point at which you update it, although I think it would be best if you update the timer based movement, make all your movements, then sync the screen.

Hope this helps

Okay, I got it working but how would I get the screen to a constant sync rate of 60? I have it calculating FPS already.
