多个场景中的AS3定时器

Question

所以，我有一个游戏，你必须活着45秒，但如果你死了它进入场景4，你可以点击重新启动场景3（这是你尝试不死的地方）。我的问题是我的计时器。我在场景3中声明了计时器，但它似乎从第一场开始，当我死了，计时器没有重启或停止，所以我可以一遍又一遍地死，只要我一直在玩总共45秒，我自动获胜。我不确定这个错误发生在哪里，所以我只是要粘贴我的所有代码。     //场景1

addEventListener(Event.ENTER_FRAME,Intro);

// whenever a hit test is performed and a timer reset is needed just call
resetTimer();

var startTime:int=getTimer();


var currentTime:int=getTimer();
trace(currentTime);




if (currentTime>45000){

}

这些都是真正重要的场景，4-6只是动画和点击鼠标等等。在场景4-6中没有引用计时器。有任何想法吗？如果需要，我会编辑额外的信息。
