Flash as2添加到变量并删除影片剪辑

Question

我已经试着解决这个问题好几个小时了，不管我怎么做，我都想不出来。我游戏中的入口应该在你收集完所有的硬币后被解锁。门户是锁定的，但当我检查一个硬币时，它既不会添加到变量中，也不会删除实例名为coin1、coin2和coin 3的影片剪辑。有人能帮我吗？

另外，如果删除影片剪辑不需要_root，我已经在没有它的情况下尝试过了，我知道这不是问题。

var openportal = 0;
function moveStuff() {
      //-Very long code that is working.    
}


if (ball_mc.hitTest(coin1._x, coin1._y)) {
    removeMovieClip(_root.coin1);
                var openportal = openportal + 1;
        }
        if (ball_mc.hitTest(coin2._x, coin2._y)) {
            removeMovieClip(_root.coin2);
                var openportal = openportal + 1;
        }
        if (ball_mc.hitTest(coin3._x, coin3._y)) {
            removeMovieClip(_root.coin3);
                var openportal = openportal + 1;
        }

        if (openportal >= 3){
           if (goal1_mc.hitTest(ball_mc._x, ball_mc._y)) {
                gotoAndStop(2);
           }
        }
ball_mc.onEnterFrame = moveStuff;

试试这个：

var openportal = 0;
function moveStuff() {
      //-Very long code that is working.    
}

        if (ball_mc.hitTest(coin1._x, coin1._y)) {
            _root.removeMovieClip(coin1);
            openportal++;
        }
        if (ball_mc.hitTest(coin2._x, coin2._y)) {
            _root.removeMovieClip(coin2);
            openportal++;
        }
        if (ball_mc.hitTest(coin3._x, coin3._y)) {
            _root.removeMovieClip(coin3);
             openportal++;
        }

        if (openportal >= 3){
           if (goal1_mc.hitTest(ball_mc._x, ball_mc._y)) {
                gotoAndStop(2);
           }
        }
ball_mc.onEnterFrame = moveStuff;
