Flash CS3删除舞台上的对象

Question

好的，这个小游戏在我的主时间线里。小型游戏使用addChild(新a0)、新a1、新a2等工具动态地在数组中创建一组对象。无论如何，在游戏结束时，有一个选项可以重新启动(重置分数并返回开始帧)或完成(返回几帧到“主屏幕”，该屏幕位于另一层，并返回几个帧)。如果我选择任何一个选项，任何没有删除的对象，从游戏中删除(得到一个匹配)留在舞台上，即使是重新开始或回到主框架。我尝试过各种方法来调用removeChild，将数组设置为空，什么不是，但我似乎找不出如何删除它们。在这里显示的代码中，我得到了以下错误：

ArgumentError:错误#2025年:提供的DisplayObject必须是调用方的子级。在flash.display::DisplayObjectContainer/removeChild() at mousiesDay_fla::MainTimeline/clearGame()mousiesDay_fla.MainTimeline::frame258:11 at mousiesDay_fla::MainTimeline/tryAgain()mousiesDay_fla.MainTimeline::frame258:29

这是代码

scoreWindowText.visible = false;
finBtn.visible = false;
tryBtn.visible = false;
finBtn.removeEventListener(MouseEvent.CLICK, finished);
tryBtn.removeEventListener(MouseEvent.CLICK, tryAgain);

function clearGame() {
    for( var i:int = 0; i < numClips; i++ ) {
        removeChild( myClip[i] );

    }
    myClip.length = 0;
    scoreWindow.visible = false;
    scoreWindowText.visible = false;
    finBtn.visible = false;
    tryBtn.visible = false;
    finBtn.removeEventListener(MouseEvent.CLICK, finished);
    tryBtn.removeEventListener(MouseEvent.CLICK, tryAgain);
}

    clearGame();
    gotoAndPlay(256);
}

    clearGame();

我应该指出，如果您查看我执行testHitObject的代码的末尾，然后在此之后调用removeChild，则该特定的delete工作并从框架中删除该对象。

Answer 1

这个问题也解决了。我可能应该花更多的时间，然后我发布这些。

事实证明，当对象被匹配时，它们将按照正在工作的removeChild()函数被移除。当时我所做的是遍历数组并尝试删除一些已经删除的对象。因此，我所做的是保留一个与对象匹配的数组，当对象被移除时，将一个标志更改为0。最后，迭代新数组，如果有1，则使用相同的索引从数组中删除子对象。如果有0，忽略它。现在起作用了。
