actionscript - removeChild 使用不正确？

Question

我只是想在双击时从舞台上删除一个电影剪辑

package  {
    import flash.display.MovieClip;
    import flash.events.MouseEvent;
    import fl.motion.MotionEvent;

    public class Main extends MovieClip{

        var thingeh:Things;

        public function Main() {
            thingeh = new Things;
            stage.addEventListener(MouseEvent.CLICK, onClick);
            stage.addEventListener(MouseEvent.DOUBLE_CLICK, onDouble);

        }

        public function onClick(event:MouseEvent)
        {
            addChild(thingeh);

        }
        public function onDouble(event:MouseEvent)
        {
            if(thingeh)
            removeChild(thingeh);

        }
    }

}

Answer 1

public function onDouble(event:MouseEvent)
{
    if( thingeh && contains(thingeh) )
    {
        removeChild(thingeh);
    }
}

此外，您可能希望doubleClickEnabled = true在您的构造函数中。

请注意，与事件MouseEvent.CLICK一起被解雇两次。MouseEvent.DOUBLE_CLICK
