Fast Flash Tweening Engine: TweenLite

TweenLite is a lightweight and fast tweening engine for Flash AS2 & AS3.

It is lightweight because it only takes 3kb when published which makes it one of the smallest tweening engines around. And you can extend it with TweenFilterLite and TweenMax to add ColorMatrixFilter effects like saturation, contrast, brightness, hue, and even colorization.

Why use TweenLite rather than built-in tweening engine?

• SPEED. TweenLite is much faster.
• onComplete, onStart, onUpdate callbacks (plus the ability to pass any number of variables to them)
• autoAlpha (toggles visibility of an object off when the alpha hits zero)
• Tween multiple properties with a single call
• Delay any tween by a set amount (good for sequencing)
• Tween the tint of any MovieClip/Sprite VERY easily
• Tween the volume of any MovieClip
• more..

Usage of TweenLite is very simple:

TweenLite.to(target:Object, duration:Number, variables:Object);

is the most basic usage. You can add more variables that can be found at the product page.
