Question

IndexOutOfRangeException：数组索引超出范围。 WordScramble.ShowScramble（Int32索引，Int32索引2）（在Assets / Word Sramble / WordScramble.cs：210） WordScramble.Start（）（在Assets / Word Sramble / WordScramble.cs：134）

public void ShowScramble(int index, int index2)
{
    textObjects.Clear ();
    charObjects.Clear ();
    foreach (Transform child in container) 
    {
        Destroy (child.gameObject);
    }


    //WORDS FINISHED
    //SHOW RESULT SCREEN
    if ((index > words.Length - 1) && (index2 > questions.Length - 1))
    {
        result.ShowResult();
        wordCanvas.SetActive(false);
        //Debug.Log ("index out of range, please enter range between 0-" + (words.Length - 1).ToString());
        return;
    }


    char[] chars = words [index].GetString ().ToCharArray ();
    char[] chars2 = questions [index2].GetString ().ToCharArray ();
    foreach (char c in chars) 
    {
        TextObject clone2 = Instantiate (prefabQstn.gameObject).GetComponent<TextObject> ();
        CharObject clone = Instantiate (prefab.gameObject).GetComponent<CharObject> ();

        clone.transform.SetParent (container);
        clone2.transform.SetParent (containerQstn);
        textObjects.Add (clone2.Init (c));
        charObjects.Add (clone.Init (c));

    }

    currentQstn = index2;
    currentWord = index;
    StartCoroutine (TimeLimit());
}

索引检查未正确完成。需要进行OR操作。否则两个索引都必须超出范围才能满足条件。

if ((index > words.Length - 1) || (index2 > questions.Length - 1))

包含负数测试可能是个好主意：

if ((index > words.Length - 1) || (index2 > questions.Length - 1) || index < 0 || index2 < 0)

您未在以下代码中使用chars2数组，因此请考虑正确更改代码。但我想这一切都取决于你希望代码做什么。
