我知道 Unity3D StartCoroutine 调用一个与 StartCoroutine 在同一线程上运行的函数,但是被调用的函数什么时候返回到原始调用者?
最佳答案
我在互联网上四处寻找一个很好的 Unity3D 协程示例,但找不到完整的示例。有一个 great explanation由 UnityGems 提供,但即使是他们的示例也不完整。所以我写了自己的例子。
这个:
using UnityEngine;
using System.Collections;
public class MainCamera: MonoBehaviour {
void Start () {
Debug.Log ("About to StartCoroutine");
StartCoroutine(TestCoroutine());
Debug.Log ("Back from StartCoroutine");
}
IEnumerator TestCoroutine(){
Debug.Log ("about to yield return WaitForSeconds(1)");
yield return new WaitForSeconds(1);
Debug.Log ("Just waited 1 second");
yield return new WaitForSeconds(1);
Debug.Log ("Just waited another second");
yield break;
Debug.Log ("You'll never see this"); // produces a dead code warning
}
}
产生这个输出:
About to StartCoroutine
about to yield return WaitForSeconds(1)
Back from StartCoroutine
Just waited 1 second
Just waited another second
关于c# - Unity3D StartCoroutine调用一个函数,那个函数什么时候返回?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/18855983/
