I've found anecdotally the onEnterFrames are less CPU intensive than a setInterval running at a similar rate.
The cons of setInterval are worth noting, but if you're using a good OOP code design, and you're strict about tracking your interval IDs, then you don't have to be too afraid of setInterval. I usually define a single member variable in a class to track a particular interval. Any time I want to call set interval, I first make sure the interval is cleared. ... if(this.intervalId) clearInterval(this.intervalId); this.intervalId = setInterval(this, "someMethod", time); Seems to work pretty well. There is also a gotcha related to onEnterFrame that's worth mentioning: A MovieClip can only have a single onEnterFrame handler, so when you assign an event handler to some MovieClip you'd better make sure it doesn't already have a different onEnterFrame already assigned to it. I've run into this kind of thing when working with animations from artists who like to put a lot of Actionscript functionality into their MovieClips. -Adam On 5/24/06, Rifled Cloaca <[EMAIL PROTECTED]> wrote:
Flashcoders, I'm building a modular system that contains various programmatic animations within seperate modules, coordinated by a central wrapper class. I've opted to use empty movieclips with onEnterFrame functions to manage timing in animations and presentation playback, as opposed to setInterval. Reason being is that I don't want to have to worry about scoping my intervals, and most of all, losing track of intervals and eventually having them stack up, interfere with eachother, and cause memory leaks. Question is, isn't it more processor intensive to use a series of onEnterFrames like this? Can anyone think of any other cons to the method I've chosen?
