Sun Qiqung accompany you to learn the--unity3d process pause

When doing unity3d projects, it is sometimes necessary to let the process pause for a while.
It is suggested that yield return new waitforseconds (value) be used, as follows:
IEnumerator Wait (float value)//Waiting time, per second
{
Print (time.time);
Yield return new waitforseconds (value);
Print (time.time);
}
void Start ()
{
Startcoroutine (Wait (1.0f));
}
But when I use it, it's useless. The same is true for multiple tests.
Helpless, using Thread.Sleep (); A lot of people say this works with unity will crash,
But that's what I'm using, okay, here's the usage:
Using System.Threading;
Thread.Sleep (2000);
