Actionscript 3 事件侦听器赢得'；我不会在AS3附近第二次工作

我卡住了！如果我需要更详细的说明，请留下评论，我会详细说明

我尝试创建一些代码，动态地将链接对象添加到stage，然后在正确的区域中删除，然后创建下一个，以此类推。信息在一个数组中循环，直到游戏完成并达到targetScore。如果计时器用完，游戏停止，调用win（）或lose（）函数，并显示重试按钮。在游戏停止，我尝试使用retry（）函数重新启动程序之前，这一切都很正常。函数的作用是：再次创建棒球对象，然后让releaseToDrop（）像第一次一样重复所有操作，从而尝试按程序启动时的状态重置所有操作。根据我停止的位置，当我第二次到达同一位置时，clicktoDrag1（）函数无法拾取当前对象。它可以位于从库中动态创建的8个对象中的任意1个对象上。当stage听到侦听器在*mouse_up*上的声音时，我可以单击并拖动该对象，但当它与数组（在retry（）函数中重置）稍微不同步时，该对象就会崩溃，即使所有的trace语句都按应有的方式读取，被丢弃的目标也无法识别它。我知道这是一个很大的看虽然，我不知道这是否可以通过论坛解决，但任何一般提示将不胜感激

我通常保持代码简单，但我想让代码自行编写，直到事情变得太复杂为止

我以前从未发过帖子寻求帮助，但我已经给了这一切，如果无法修复，我将不得不重新开始并简化

提前感谢如果有人花时间看这篇文章，我会感到很谦卑，并希望更多地利用这个论坛，成为一名更好的程序员

OP已解决问题，如图所示：

我并没有在游戏结束时移除这个物体，我把它藏起来了，所以当它再次出现时，一个复制品就被创造出来了。我把它拿走了，而不是藏起来，效果很好。在舞台上有两个视频片段会产生一些奇怪的拖放行为，这有点让人泄气。“这不是‘我的’答案。MAngoPop在评论中回答了这一问题，但忘记将其作为答案添加。”

这只是一个猜测，但可能是在

This.setChildIndex（draggable，This.numChildren-1）行中将numChildren索引设置为另一个负1？因此，如果第一轮1是1，那么负1=0，那么在下一轮（重播）中，它将被设置为-1，结果是…？嗨，谢谢，我尝试了，但问题仍然存在。我开始认为，当游戏停止时，它不会删除应用于当前舞台上对象的当前侦听器，因此当它在第二次出现时，会出现某种冲突。事件侦听器是在releaseToDrop（）函数中添加和删除的，所以我想我必须正确地删除它？我会设法解决这个问题，并向你汇报！这听起来确实很容易理解。对于这一点，您可以尝试在游戏中的几个点跟踪函数（尽管我不知道您可以期望什么样的输出），或者将行
stage.addEventListener（MouseEvent.MOUSE_UP，releaseToDrop）
在clickToDrag1函数的末尾，而不是在它的外部（在`draggable.startDrag（）；`之后，右大括号之前）。另外，我假设您的EventListener放在主函数的内部？因为你所有的变量，它们的属性和函数调用都不在任何函数或类中。我并没有在游戏结束时移除这个物体，我把它藏起来了，所以当它再次出现时，一个复制品就被创造出来了。我把它拿走了，而不是藏起来，效果很好。舞台上有两个视频片段，造成了一些奇怪的拖拽行为，这有点让人泄气。再次感谢，您的想法激发了解决方案+谢谢你，沃尔特。你可能想考虑把这个标记为社区维基，因为一些用户可能会否决你的“信用”（虽然没有特别的规则反对你所做的）。有关此特定答案的讨论，请参阅@Cyborgx37。没问题。当人们不将答案作为“答案”发布时，我很恼火。当它在2012年被解决时，它在搜索结果中显示为未解决。我不知道有什么方法可以向人们传达关于这件事的信息，否则我会向MangoPop发送信息。谢谢你的提示。我更新了它并将其作为wiki进行了检查。您可以对该问题留下评论，该评论将在用户下次登录时显示为通知。不过，并不是所有的用户都非常活跃，也不是所有的用户都愿意更新他们的Q/A。您所做的是正确的方法，但请记住要将非原创作品归因于。
