brightnessTransform.rb = -30;

brightnessTransform.bb = -30;

brightnessTransform.gb = -30;

brightness.setTransform(brightnessTransform);

This last example adds a new method, MovieClip.doMouseFade(), that brightens and

darkens a clip according to the mouse position:

MovieClip.prototype.doMouseFade = function () {

var brightness = new Color(this);

var brightnessTransform = new Object();

this.onMouseMove = function () {

var brightnessAmount = -255 + (_level0._xmouse / Stage.width) * 510;

brightnessTransform.rb = brightnessAmount;

brightnessTransform.bb = brightnessAmount;

brightnessTransform.gb = brightnessAmount;

brightness.setTransform(brightnessTransform);

updateAfterEvent();

}

}

box.doMouseFade();
