在Unity中制作计时器 [英] Making a timer in Unity

问题描述

我在Unity中遇到问题.我的项目需要倒数计时.但是，此倒计时将计数2次.例如，将完成一项工作3秒，完成另一项工作2秒，然后这些工作将继续.

I have a problem in Unity. I need a countdown in my project. But this countdown will count 2 times. For example, 3 seconds a job will be done, 2 seconds another job will be done and these works will continue.

推荐答案

协程(以及更多协程)

协程完全可以完成您想做的事情.

Couroutines (and more Coroutines)

Coroutines do exactly the thing you want to do.

private IEnumerator Countdown2() {
    while(true) {
        yield return new WaitForSeconds(2); //wait 2 seconds
        //do thing
    }
}

private IEnumerator Countdown3() {
    while(true) {
        yield return new WaitForSeconds(3); //wait 3 seconds
        //do other thing
    }
}

然后，您可以通过调用Start()方法(或任何地方)来启动它们:

You then start them off by calling in your Start() method (or where ever):

void Start() {
    StartCoroutine(Countdown2());
    StartCoroutine(Countdown3());
}

请注意，除非发生以下三种情况之一，否则这两种倒计时方法都会永远起作用:

Note that both countdown methods will do their thing forever unless one of three things happens:

调用
1. StopCoroutine(...)，传入StartCoroutine
返回的引用
2. 倒数功能本身返回(除非它打破无限while(true)循环，否则不会发生)
3. coundown函数本身调用yield break

1. StopCoroutine(...) is called, passing in the reference returned by StartCoroutine
2. The countdown function itself returns (which will not happen unless it breaks out of the infinite while(true) loop)
3. The coundown function itself calls yield break

还要注意，如果两个协程都应在同一时间(例如6秒)恢复，协程2将首先执行(首先启动)，除非有其他效果干预(例如，其中一个循环具有另一个yield指令，其中一个循环终止，等等).

Also note that in the event both coroutines should resume at the same time (e.g. at 6 seconds) coroutine 2 will execute first (as it was started first), unless some other effect intervenes (e.g. one of the loops has another yield instruction, one of the loops is terminated, etc).
