//in my papervision scene…

//in the Face Class…

package {

import flash.events.*;

public class Face extends MovieClip {

private const TRANS_TIME:Number = .5;

public function Face() {
init();
}

private function init():void {
addEventListener(MouseEvent.ROLL_OVER, RollOver);
addEventListener(MouseEvent.ROLL_OUT, RollOut);
}

private function RollOver(e:MouseEvent):void {
Tweener.addTween(this.icon,{alpha:1, time:TRANS_TIME, transition:”linear”});
}

private function RollOut(e:MouseEvent):void {
Tweener.addTween(this.icon,{alpha:.5, time:TRANS_TIME, transition:”linear”});
}
}
}

FrontFace is a linked movieclip with Face as the baseclass…

Any help is greatly appreciated
