Question

我知道这个问题已经发布了一百万次并且我阅读了所有的答案，但我仍然无法弄清楚我的游戏中的问题在哪里，我有这个错误

TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at habitadnew_fla::MainTimeline/frame2()
    at flash.display::MovieClip/gotoAndStop()
    at habitadnew_fla::MainTimeline/fl_ClickToGoToAndStopAtFrame_11()

我一次又一次地构建我的影片剪辑和我的按钮，但我仍然收到此错误。你能帮我么。我是flash的新手。如果有人想看看我的代码我在http://snk.to/f-ctpm6nj1上传了我的游戏。

谢谢

我也是一个菜鸟，所以我不能确切地说出问题所在。我刚测试了你的，我的调试器说wormA1在

时为空

function Dropworm(event:MouseEvent):void
{
    // wormA1 IS NULL
    if (wormA1.x>455 &&wormA1.x<565 &&wormA1.y>430 &&wormA1.y<530) {
        wormA1.stopDrag();
    }
    else
    {
        wormA1.stopDrag();
        wormA1.x=753;
        wormA1.y=185;
    } 
}

希望这可能是一个线索。
