as3中tileList单元格响应鼠标事件

Question

我正在制作一个 Flash 游戏（基本上是同一个游戏的一个版本），并且我使用了一个 tileList 作为填充有 movieClip 片段的棋盘。我希望这些片段能够响应 mouseOver、mouseOut 和 mouseClick 事件。

通过查看其他问题/答案，我了解到我需要一个自定义 imageCell。这是要走的路吗？我希望通过将操作放入 movieClips 本身中来获得我想要的响应，如下所示，但这似乎不起作用。 （顺便说一句，我是这个社区的新手，但通过谷歌搜索多次来到这里……感谢你们的帮助，我已经从你们这些出色的人那里得到了帮助。干杯。）

this.addEventListener(MouseEvent.MOUSE_OVER, OverHandler);
this.addEventListener(MouseEvent.MOUSE_OUT, OutHandler);
this.addEventListener(MouseEvent.CLICK, ClickHandler);

this.stop();

function OverHandler(event:MouseEvent):void
{
event.target.play();
}

function OutHandler(event:MouseEvent):void
{
event.target.stop();
}

function ClickHandler(event:MouseEvent):void
{
    event.target.play();
}

我可能会为游戏中所有已准备好事件的部件设置一个基类。就像这样：

package
{
    import flash.display.MovieClip;
    import flash.events.MouseEvent;

    public class Piece extends MovieClip
    {
        /**
         * Constructor
         */
        public function Piece()
        {
            addEventListener(MouseEvent.CLICK, _click);
            addEventListener(MouseEvent.ROLL_OVER, _rollOver);
            addEventListener(MouseEvent.ROLL_OUT, _rollOut);
        }

        /**
         * Called on MouseEvent.CLICK
         */
        protected function _click(e:MouseEvent):void
        {
            trace(this + " was clicked");
        }

        /**
         * Called on MouseEvent.ROLL_OVER
         */
        protected function _rollOver(e:MouseEvent):void
        {
            trace(this + " was rolled over");
        }

        /**
         * Called on MouseEvent.ROLL_OUT
         */
        protected function _rollOut(e:MouseEvent):void
        {
            trace(this + " was rolled off");
        }

        /**
         * Destroys this
         */
        public function destroy():void
        {
            // listeners
            addEventListener(MouseEvent.CLICK, _click);
            addEventListener(MouseEvent.ROLL_OVER, _rollOver);
            addEventListener(MouseEvent.ROLL_OUT, _rollOut);

            // from DisplayList
            if(parent) parent.removeChild(this);
        }
    }
}

如果您需要单击、roll_over 或 roll_out 对某些部件执行任何独特的操作，只需扩展并执行此操作:

package
{
    import flash.events.MouseEvent;

    public class MyPiece extends Piece
    {
        override protected function _click(e:MouseEvent):void
        {
            trace("mypiece was clicked");
        }
    }
}
