Question

我正在使用Flash Professional制作应用。它基本上是一个先进的避免游戏，有一些物体被生成并在角色之后射击等等。当我在我的手机上打开应用程序时，它按预期顺利运行，但过了一会儿，它运行速度明显变慢，不多，但足以令人讨厌，并且会破坏体验。我一直小心使用removeChild，以便在清除级别等时删除每个对象。

我可以期待内存泄漏，因为一开始没有延迟吗？做或查看会有什么好主意？我应该使用垃圾收集，是否可以使用scout或flash builder分析应用程序？任何好的教程？提前致谢

Answer 1

当然可以使用Scout来查看你的记忆是如何被使用的。

这是一个很棒的内存跟踪类，您可以使用它来检查您的实例是否应该从内存中释放。

Answer 2

所以无论我做什么，我都无法让Adobe侦察员工作。但我确实解决了这个问题。对谁有帮助：我添加了'trace（System.totalMemory）;'在一个ENTER_FRAME函数内的文档类中，这使我能够看到我的应用程序使用了多少内存。一开始，金额不断上升。我将所有eventlisteners从主类中移动到最适合的任何类中。例如，我将'gamePanel.jetButton.addEventListener（MouseEvent.MOUSE_DOWN，jetPackUp）'移动到了gamePanel类中。为了从gamePanel类中引用主类，我使用了代码：'MovieClip（parent）.someFunction（）' 现在我几乎拥有一个不会继续使用内存的稳定应用程序。我只需要弄清楚如何处理我的for循环，这会导致内存泄漏，当我必须添加同一对象的更多实例时..但我认为'对象池'将解决这个问题。
