Example
The following example changes the shadowAlpha property on the existing MovieClip
instance (rect) when a user clicks it:
import flash.filters.BevelFilter;
var rect:MovieClip = createBevelRectangle("BevelShadowAlpha");
rect.onRelease = function() {
var filter:BevelFilter = this.filters[0];
filter.shadowAlpha = 0.2;
this.filters = new Array(filter);
}
function createBevelRectangle(name:String):MovieClip {
var w:Number = 100;
var h:Number = 100;
var bgColor:Number = 0x00CC00;
}
var rect:MovieClip = this.createEmptyMovieClip(name,
this.getNextHighestDepth());
rect.beginFill(bgColor);
rect.lineTo(w, 0);
rect.lineTo(w, h);
rect.lineTo(0, h);
rect.lineTo(0, 0);
rect._x = 20;
rect._y = 20;
var filter:BevelFilter = new BevelFilter(5, 45, 0xFFFF00, 0.8, 0x0000FF,
0.8, 20, 20, 1, 3, "inner", false);
rect.filters = new Array(filter);
return rect;
