c# - Unity StopCoroutine无法正常工作

我有一种方法可以启动协程，并且应该先停止协程并重设一些内容，然后再重新启动。

private Coroutine wholeTutorialRoutine;

public void RunWholeTutorial()
{
    tutorialText.text = "";
    StopAllCoroutines();

    if(wholeTutorialRoutine != null)
    {
        StopCoroutine(wholeTutorialRoutine);
    }

    wholeTutorialRoutine = StartCoroutine(WholeTutorial());

}

private IEnumerator WholeTutorial()
{
    // Wait until after we are done showing this dialouge
    yield return StartCoroutine(ShowDialougForSeconds("tap_to_kill", 5f));

    yield return new WaitForSeconds(5f);

    yield return StartCoroutine(ShowDialougForSeconds("larger_enemies", 5f));

    yield return new WaitForSeconds(5f);

    yield return StartCoroutine(ShowDialougForSeconds("press_button", 7f));

    yield return new WaitForSeconds(3f);

    yield return StartCoroutine(ShowDialougForSeconds("button_colors", 5f));
}

private IEnumerator ShowDialougForSeconds(string diagID, float time)
{
    SetText(diagID);

    tutorialText.GetComponent<Animator>().SetTrigger("FadeIn");

    yield return new WaitForSeconds(time);

    tutorialText.GetComponent<Animator>().SetTrigger("FadeOut");
}

wholeTutorialRoutine是类型为Coroutine的专用字段。

我觉得这些WaitForSeconds调用发生了一些时髦的事情，但是我不太确定该怎么办。

RunWholeTutorial()连接到一个按钮，所以我想停止当前教程，如果用户一遍又一遍地按它，请重新开始。

当前发生的事情似乎是协程在彼此之上运行。

最佳答案

使用IEnumerator代替Coroutine在RunWholeTutorial函数中一次存储Start协程函数的实例。然后，您可以使用该IEnumerator变量启动和停止它。

private IEnumerator wholeTutorialRoutine;

void Start()
{
    wholeTutorialRoutine = WholeTutorial();
}

public void RunWholeTutorial()
{
    tutorialText.text = "";

    if (wholeTutorialRoutine != null)
    {
        StopCoroutine(wholeTutorialRoutine);
    }

    StartCoroutine(wholeTutorialRoutine);
}

private IEnumerator WholeTutorial()
{
    // Wait until after we are done showing this dialouge
    yield return StartCoroutine(ShowDialougForSeconds("tap_to_kill", 5f));

    yield return new WaitForSeconds(5f);

    yield return StartCoroutine(ShowDialougForSeconds("larger_enemies", 5f));

    yield return new WaitForSeconds(5f);

    yield return StartCoroutine(ShowDialougForSeconds("press_button", 7f));

    yield return new WaitForSeconds(3f);

    yield return StartCoroutine(ShowDialougForSeconds("button_colors", 5f));
}

private IEnumerator ShowDialougForSeconds(string diagID, float time)
{
    SetText(diagID);

    tutorialText.GetComponent<Animator>().SetTrigger("FadeIn");

    yield return new WaitForSeconds(time);

    tutorialText.GetComponent<Animator>().SetTrigger("FadeOut");
}
