[Unity-22] Coroutine协程浅析

1.概念解释

    A coroutine is a function that is executed partially and, presuming suitable conditions are met, will be resumed at some point in the future until its work is done

2.作用与使用方法

<span style="font-family:SimSun;">IEnumerator Fun() {
    yield returnnewWaitForSeconds(5.0F);
    //do something
}</span>

b>等待其它事件完毕

<span style="font-family:SimSun;">IEnumerator Do() {
    print("1");
    yield returnnewWaitForSeconds(2);
    print("2");
}
IEnumerator Fun() {
    print("3")
    yield returnStartCoroutine(Do());
    print("4");
}</span>

<span style="font-family:SimSun;">IEnumerator Do() {
        print("1");
        yield return new WaitForSeconds(2);
        print("2");
    }
    void Fun() {
        print("3");
        StartCoroutine（Do()）;
        print("4");
    }</span>

<span style="font-family:SimSun;">Ienumerator Do()
{
    while(true)
{
    print("happy");
    yield return null;//等待这一帧结束
    //yield return new WaitForFixedUpdate(); //等待全部脚本的fixedupdate运行完成
    //yield return new WaitForEndOfFrame();
}
}</span>

<span style="font-family:SimSun;">yield return new WWWContinue()</span>
