有人可以解释一下 WaitForSeconds() 吗? [英] Can somebody please explain WaitForSeconds()?

问题描述

我试图让我的代码在做某事之前等待 x 秒.我查找了如何执行此操作，并发现了 WaitForSeconds() 函数.不幸的是，每当我尝试使用它时，我的代码中都会出现红色下划线.我试图让它在你死后等待几秒钟后再重生:

I am trying to make my code wait x seconds before doing something. I looked up how to do this, and found out about the WaitForSeconds() function. Unfortunately, whenever I try to use it I get red underlines in my code. I am trying to make it so when you die it waits a few seconds before you respawn:

 void Respawn()
{
    yield return new WaitForSeconds(5);
    gameObject.transform.position = spawnPoint;
}

我也明白我需要在某处放置诸如 StartCoroutine(Example()); 之类的东西，但我也不知道把它放在哪里.我该如何正确执行此操作?

I also understand I need to put something like StartCoroutine(Example()); somewhere but I also don't know where to put it. How do I do this properly?

推荐答案

yield return new WaitForSeconds(5); 必须在协程函数中使用.现在，您在 void 函数 void Respawn() 中使用它.将 void 更改为 IEnumerator 应该可以解决您的问题.

yield return new WaitForSeconds(5); must be used in a coroutine function. Right now, you are using it in a void function void Respawn(). Changing the void to IEnumerator should fix your problem.

IEnumerator Respawn()
{
    yield return new WaitForSeconds(5);
    gameObject.transform.position = spawnPoint;
}

然后你可以用StartCoroutine(Respawn());调用它.每次调用它都会等待5秒，然后执行gameObject.transform.position = spawnPoint;.如果您想了解其工作原理，请访问此处.

Then you can call it with StartCoroutine(Respawn());. Each time you call it, it will wait for 5 seconds, then execute gameObject.transform.position = spawnPoint;. Visit here if you want to learn how it works.
