getTimer() 将返回一个整数，表示从 Flash 启动开始的确切毫秒数.

getTimer() will return an int of exactly how many milliseconds from when flash started.

import flash.utils.getTimer;

var myInt:int = getTimer() * 0.001;

myInt 现在将是程序运行了多少秒.

myInt will now be however many seconds the program has been running.

哦要知道它已经运行了多长时间，只需保留初始 myInt 并根据当前计时器检查它.

edit: oh to tell how long it has been running just keep the initial myInt and check it against the current timer.

所以当游戏第一次开始时.

so when the game first starts.

var startTime:int = getTimer();

然后是每一帧或任何你需要检查的时候.

then every frame or whenever you need to check it.

var currentTime:int = getTimer();


var timeRunning:int = (currentTime - startTime) * 0.001; // this is how many seconds the game has been running.
