Stuttering of animation due to CPU intensive operation

[Jack 0 Likes (Newbie)]

My animation (a rotating loading indicator) occasionally stalls as my app is processing some code. Is there a way to avoid this? Is there a way to make the animation run on the GPU rather than the CPU? Any ideas are welcomed!

 

thanks,

Jack

 

Below is the code that I run. The displayObject "_spCenter" is a circular loading indicator:

private function rotate():void {
  if(_tween == null || !_tween.active){
  _tween = new TweenLite(_spCenter, .6, {rotation: 355, ease: Linear.easeInOut, onComplete:rotate});
  }
}

nope. if flash is processing an intensive amount of code the next frame will not render until that code is processed.

 

I am not aware of any work-arounds for this.

What about Stage3D? Is that something to look into?

I doubt Stage3D will solve your problem or that the rotation is really the source anyway, but I will point out that using TransformMatrixPlugin to do the rotation may be a bit smoother - see the interactive example at http://www.greensock.com/tweening-tips/ (first tip)

try to divide calculations over multiple frames:
