Gradient Tween for Animated backgrounds

The gradient tween for animated backgrounds is an AS3 class that tweens every possible gradient property: colors, alphas, ratios, focalPointRatio, rotation as well as width, height and x and y position of the gradient box. All of these are specified by an XML file.

So you can create limitless animated backgrounds, and with a small xml file of around 1k and a compiled swf of 5k this animated background is also small enough to be used behind a preloader.

You can also control the duration of each tween, the easing method to use, the spread method and the interpolation method and of course the speed at which the animation runs.

I’ve also paid close attention to the performance of the class, to save on system resources the class only tweens what it has to.
