[AS3] Dynamic Timer based on FPS... ideas?

[ICD2k3]

Hey guys, so basically I'm making a processor intensive webcam motion detection game. The motion detection is called using a timer at that runs every fraction of a second.

The problem: on slower computers the game slows way down... when I increase the interval wait time it fixes the issue (with slightly less responsive motion detection)... so it seems I need some way to create a dynamic timer that can change it's delay time based on a user's FPS... I already have a script that gets FPS (counter-productively it makes it even slower cause it uses an enterframe).

Any suggestions to this issue would be greatly greatly appreciated.

Stick the motion detection code in an onEnterFrame event instead. As the frame rate slows your motion detection code gets run fewer times & as it picks up, more times.

If you don't want to run it as many times as once per frame do this sort of thing...

frameCnt = 0;
this.addEventListener(Event.ENTER_FRAME, motionDetect);

function motionDetect(e:Event):void
{
if(frameCnt%4 == 0) {
// motion detect code
}
frameCnt ++;
}

which will run your code every 4 frames.
