alphaMultiplier (ColorTransform.alphaMultiplier property) -- Flash CS3

If you set the alpha transparency value of a movie clip directly by using the MovieClip._alpha property, it affects the value of the alphaMultiplier property of that movie clip's ColorTransform object.

Example

The following example creates the ColorTransform object colorTrans and adjusts its alphaMultiplier value from 1 to 0.5.

import flash.geom.ColorTransform;
import flash.geom.Transform;

var colorTrans:ColorTransform = new ColorTransform();
trace(colorTrans.alphaMultiplier); // 1

colorTrans.alphaMultiplier = 0.5; 
trace(colorTrans.alphaMultiplier); // 0.5

var rect:MovieClip = createRectangle(20, 80, 0x000000);
var trans:Transform = new Transform(rect);
trans.colorTransform = colorTrans;

function createRectangle(width:Number, height:Number, color:Number, scope:MovieClip):MovieClip {
    scope = (scope == undefined) ? this : scope;
    var depth:Number = scope.getNextHighestDepth();
    var mc:MovieClip = scope.createEmptyMovieClip("mc_" + depth, depth);
    mc.beginFill(color);
    mc.lineTo(0, height);
    mc.lineTo(width, height);
    mc.lineTo(width, 0);
    mc.lineTo(0, 0);
    return mc;
}
