Update (March 25th, 2009) : Grant Skinner’s gTween and Tweenlite are being merged.

There are a lot Tween engines out there. Here are a couple available for Actionscript development.

  • The FuseKit. (AS2-based tween engine. Moses Gunesch manages this site. I discovered this tween library at Lee Brimelow‘s Flash tutorial site at gotoandlearn.)
  • The GOASAP site is Moses Gunesch’s AS3 Tween engine library
  • Grant Skinner did a major rewrite of his gTween engine recently (Feb 2nd, 2009).
  • KitchenSync (I first came across this at the Head conference online conference.)
  • Tweener (Available for AS2 and AS3. The documentation is very helpful. I use this library for my AS2 development.)
  • Tweenlite (Recommended by Papervision2D’s blog.)

When I had scoured sites over the internet, I could not really find any preference over the other. With exception to Papervision 3D Tutorial site, a blogger named Charlie [If somebody can tell me his name, I would like to know] recommened Tweenlite over Tweener for its superior speed rendering. Anyway, I am sure that someone will have some kind of speed comparison tests.


  1. My personal favorite is also TweenLite; here are 2 benchmarks that say that it is really fast

    I hope this help

  2. Thanks!

  3. Hey Davey,

    Enjoyed the article. I noticed the link back to my site, much appreciated. I originally used Tweener as my tween engine of choice until I was introduced to TweenLite / TweenMax. In most instances you will not notice the difference between the two; but take a look at this comparison.
