Unity StopCoroutine不工作

Question

我有一個方法來啓動協程，並應該停止它並重新啓動它之前重新設置一些事情。

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Coroutine類型的私有字段。

我覺得有些事情發生在那些WaitForSeconds調用中，但我不確定是什麼。

RunWholeTutorial()連接到一個按鈕，所以我想停止當前的教程，並重新開始，如果用戶反覆按下它。

目前發生的情況似乎是協程運行在另一個之上。

，而不是使用IEnumeratorCoroutine到RunWholeTutorial協程功能一次的實例存儲在Start功能。然後，您可以使用該變量來啓動和停止它。

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"); 
}
