actionscript 3 如何跟踪经过的时间?

问题描述

我是 actionscript3 flash 的新手.我有一个 int 变量，我想自游戏开始后每秒添加 +2.我怎样才能做到这一点 ?我怎么知道已经过去了多少时间?提前致谢！

im new to actionscript3 flash. I have a int variable and i would like to add +2 every second since game started. How can i do this ? how do i know how much time has elapsed? thanks in advance!

推荐答案

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.
