Actionscript 3 单击按钮播放动画。动作脚本

嗨，我一直收到错误信息：

TypeError: Error #1010: A term is undefined and has no properties.
at Untitled_fla::MainTimeline/myPlay_clickHandler()

当我执行代码时。有人能帮帮我吗？我看不出哪里出了问题

myAnimation.stop();
myPlayButton.stop();
myPlayButton.addEventListener(MouseEvent.CLICK, myPlay_clickHandler);

function myPlay_clickHandler(event:MouseEvent)//Creating function for the Click Event      handler
{
    if(myPlayButton.MovieClip.currentFrame ==1)
    {
        myPlayButton.gotoAndStop(2);
        myAnimation.play();
    }

    trace("myPlay was clicked on");
}

您不需要“if（myPlayButton.MovieClip.currentFrame==1）”中的“MovieClip”。如果“myPlayButton”是MovieClip，则可以直接访问其当前帧，即：

if (myPlayButton.currentFrame == 1)
