参考视频：# Unity async / await: Coroutine’s Hot Sister [C# & Unity]
协程是Unity提供的异步解决方法，但是实际应用时有诸多不便与不优雅之处。本文将用几个例子对比参照协程与await/async关键字。当然，Unity指出，在Unity中写多线程代码应当参考Unity - Manual: C# Job System
旧例
利用协程转动三个物体，并使得这三个物体逐个停止。
给出下列协程:
1
2
3
4
5
6
7
8
9
10
11
12

| using System.Collections;
using UnityEngine;
public class Shape: MonoBehaviour()
{
public IEnumerator RotateForSeconds(float duration)
{
var end = Time.time + duration;
while(Time.time < end)
{
transform.Rotate(new Vector3(1,1)*Time.deltaTime*150;
yield return null;
}
}
}
