MouseOver 事件有 TypeError: Error #1009，有什么帮助吗？

Question

我正在创建一些涉及鼠标悬停、鼠标悬停和鼠标按下事件的动画。每当我将鼠标按下影片剪辑并转到另一帧时，输出框中将出现常见错误 1009。动画有效，但错误仍然出现，我可以忽略动画有效后的错误吗？或者有什么办法可以解决我的编码问题？任何帮助深表感谢！！！

下面是影片剪辑的编码：

africaMiddleEast.addEventListener(MouseEvent.MOUSE_OVER,mover);
africaMiddleEast.addEventListener(MouseEvent.MOUSE_OUT,moverout);
africaMiddleEast.addEventListener(MouseEvent.MOUSE_DOWN,mdown);


function mover(e:MouseEvent):void{
    africaMiddleEast.gotoAndPlay(2);
}

function moverout(e:MouseEvent):void{
    africaMiddleEast.gotoAndStop(1);
}

function mdown(e:MouseEvent):void{
    gotoAndPlay(2);
}

Answer 1

您可能需要在 gotoAndPlay(2);

之前取消订阅所有事件

africaMiddleEast.addEventListener(MouseEvent.MOUSE_OUT, onOut);
africaMiddleEast.addEventListener(MouseEvent.MOUSE_OVER, onOver);
africaMiddleEast.addEventListener(MouseEvent.MOUSE_DOWN, onDown);

function onOut(e:MouseEvent):void
{
    africaMiddleEast.gotoAndStop(1);
}

function onOver(e:MouseEvent):void
{
    africaMiddleEast.gotoAndPlay(2);
}

function onDown(e:MouseEvent):void
{
    africaMiddleEast.removeEventListener(MouseEvent.MOUSE_OUT, onOut);
    africaMiddleEast.removeEventListener(MouseEvent.MOUSE_OVER, onOver);
    africaMiddleEast.removeEventListener(MouseEvent.MOUSE_DOWN, onDown);

    gotoAndPlay(2);
}
