events - 在对象外部开始单击时防止 MouseUp

Question

我有 Sprite 对象，它是一个扑克筹码。当用户点击它时，出价会增加。我正在提高对MouseUp活动的出价。但是，如果用户在对象/芯片之外开始单击，然后将鼠标拖到芯片上并执行此操作MouseUp，它会触发映射到的函数MouseUp。如果单击从对象外部开始，如何防止它触发。

this.addEventListener(MouseEvent.MOUSE_DOWN, pressChipDown)
this.addEventListener(MouseEvent.MOUSE_UP, pressChipUp)
this.addEventListener(MouseEvent.MOUSE_OUT, pressChipOut)



private function pressChipDown(e:MouseEvent):void
    {
        super.x = startX + 5;
        super.y = startY + 5;
    }

    private function pressChipUp(e:MouseEvent):void
    {
        increaseBid();
        super.x = startX;
        super.y = startY;
    }

    private function pressChipOut(e:MouseEvent):void
    {
        if(e.buttonDown) //if mouse button is down, move chip back but dont increase bid
        {
            pressChipUp(MouseEvent.MOUSE_OUT as MouseEvent)
        }
    }

谢谢

翻滚时，开始听鼠标向下和鼠标向上，如果在向下之前先向上，那就是“假”

this.addeventlistener(MouseEvent.ROLL_OVER, onOver)
