[AS3]as3下生成随机数random源代码示例

用NumberUtilities.random(1,6)方法产生随机数

            this.addChild(sprite); 
            sprite.addEventListener(MouseEvent.CLICK,OnClick); 
            OnClick(null); //CuPlayer.com提示第一次显示出来  
        } 
         
        private function OnClick(event:MouseEvent):void 
        { 
            sprite.graphics.clear(); 
            sprite.graphics.beginFill(0xFFFFFF);
