Just an idea - you could use TweenLite with an onUpdate to do something like:
var frequency:Number = 0.05; //number between 0 and 1 indicating how often your
function should get called over the course of time
var myObject:Object = {progress:0};
var nextTrigger:Number = frequency;
TweenLite.to(myObject, 5, {progress:1, ease:Strong.easeIn,
onUpdate:checkProgress});
function checkProgress():void {
if (myObject.progress >= nextTrigger) {
myFunction();
nextTrigger = myObject.progress + frequency;
}
}
Then you can swap out the easing equation with whichever one you want. Or build
a custom ease with something like http://blog.greensock.com/customease/. And in
the example, the tween lasts 5 seconds, but obviously change that to whatever
you need.
Warning: The updates are based on the frame rate, so this method does not
guarantee that the function will get called at precise increments, nor does it
guarantee that the function will be called a certain number of times, but since
your stuff doesn't render inbetween frames anyway, I believe it should
generally produce the results you're after (easing the time between function
calls). If not, ignore this post - it was just an idea I had off the top of my
head :)

Subject: Re: [Flashcoders] Easing a selection
I use TweenLite daily, but I am not tweening the properties on a
DisplayObject, I am "easing" the call of methods over time.
I believe that a timer, setting the delay after each call, and based on a
number of times to call might serve me well.
