我的朋友和我必须从零开始为学校创建一个Flash游戏。游戏运行良好，直到我们通过屏幕到达游戏。我一直试图禁用对象计时器，以便加电和敌人进入屏幕，没有运气。 此外，当我尝试重新启动游戏时，它会从上一个游戏结束的地方开始。以同样的速度，敌人等。有没有办法重置它？

要停止Timer，您需要致电stop()或reset()。如果你想让它完全消失，你也想从计时器中删除事件监听器并将其设置为null。
要做任何这些事情，您需要对计时器对象的引用。最简单的方法是将计时器创建为Main类的实例变量（而不是像现在那样创建局部变量）。如果您不想这样做，您还可以使用currentTarget的TimerEvent属性从事件处理程序内部获取对Timer的引用。
