A Lightweight (2K) and FAST Tweening Engine in AS3: TweenLite

While we a re still waiting for Zigo/Fuse to update their engine, I started using TweenLite, and really start liking it.

It is light (2kB), and fast, does rely on flashes built in easing classes though. It is rather basic, but useful for almost all purposes.
here a simple example, of a sequenced animation with :

  import gs.TweenLite;
  import fl.motion.easing.Elastic;
  TweenLite.to(mc_my, 0.8, {x:120, y:143,ease:Elastic.easeOut,delay:2,onComplete:onFinishTween, onCompleteParams:[5, mc_my],overwrite:false});
  private function onFinishTween(Num,target_mc){
    trace("tween finished "+target_mc
  }
