Yo!Before launching the official Tweening Package (with proper Interfaces and classes to implement any kind of tweens, and of course with the default Basic Tweening classes).After 4 tween engine implementations I can say I acchieved sort of state of art in tweening matters. With past experience I:Found a class pattern that makes the tween system expandable to any kind of tweens (and can be implemented in virtually any language - actually I perfectly ported this to C#).Created a way to compact all Transition functions in order to reduce file size.Simplified the engine a lot in order to make the update operation as fast as possible.The result of this (besides the package) is a stupidly small tweening class!!The ByteTween static class eats only 1.7Kb of compiled clip! WIth this size it supports:

• Creation of tweens of any numeric property (not color/uint propperties).
• Pause,Unpause,Cancel operations based on the tween target and property.
• Overlap system that cancel tweens of same property in order to avoid erroneous behaviour
• Alpha tween with negative alpha support (negative alpha sets the MovieClip visibility to false)
• ’scale’ tween of both ’scaleX’ and ’scaleY’ properties.
• OnComplete callback with any number of parameters
• Easy interface for creating new tweens!

The source file of ByteTween is in the Google Code of the Lighter project. In a few days I’ll created a proper project to all new classes that will come up!Together with the source you can find a ExmpleFile to see the creation of a simple tween!

 ** Edit: I didn`t have much tim to test 100% this code. I have strong belief that it`s perfect but any issue report in the code.google interface!
