索引越界错误单位c#

Question

以下示例运行良好，但给出的错误索引超出了范围。有人知道我该怎么修吗？

我的另一个问题是，我无法初始化触摸位置上的对象。谢谢

void Update ()
    {
        goldDisplay.text = "Gold " + gold;
    if (Input.GetKeyDown(KeyCode.Space) || Input.GetTouch(0).phase == TouchPhase.Began) {
        int rarityRoll = UnityEngine.Random.Range (0, 100);
        if (rarityRoll < 99) {
            // choose something from common
            int roll = UnityEngine.Random.Range (0, commons.Length);
            // instantiate
            Instantiate (commons [roll].componentObjc, new Vector3(0,0,1), transform.rotation);
            } else {
            int roll = UnityEngine.Random.Range (0, rares.Length);
            // instantiate
            Instantiate (rares [roll].componentObjc, new Vector3(0,0,1), transform.rotation);
        }
    }
}

修复。它工作时没有错误

void Update ()
    {
    goldDisplay.text = "Gold " + gold;
    for (int i = 0; i < Input.touchCount; i++)
    {
        Touch touch = Input.GetTouch(i);
        if (touch.phase == TouchPhase.Ended && touch.tapCount == 1)
        {
            Vector3 position = Camera.main.ScreenToWorldPoint(touch.position);
            int rarityRoll = UnityEngine.Random.Range (0, 100);
            if (rarityRoll < 99) {
                // choose something from common
                int roll = UnityEngine.Random.Range (0, commons.Length);
                // instantiate
                Instantiate (commons [roll].componentObjc, new Vector3 (0, 0, 1), transform.rotation);
            } else {
                int roll = UnityEngine.Random.Range (0, rares.Length);
                // instantiate
                Instantiate (rares [roll].componentObjc, new Vector3 (0, 0, 1), transform.rotation);
            }
        } 
    }
}

Input.GetTouch(0).phase有错误，您应该使用Input.touches[0].phase将blow代码替换为您的代码！ void Update () { goldDisplay.text = "Gold " + gold;

if (Input.GetKeyDown(KeyCode.Space) || Input.touches[0].phase == TouchPhase.Began) {
    int rarityRoll = UnityEngine.Random.Range (0, 100);
    if (rarityRoll < 99) {
        // choose something from common
        int roll = UnityEngine.Random.Range (0, commons.Length);
        // instantiate
        Instantiate (commons [roll].componentObjc, new Vector3(0,0,1), transform.rotation);
        } else {
        int roll = UnityEngine.Random.Range (0, rares.Length);
        // instantiate
        Instantiate (rares [roll].componentObjc, new Vector3(0,0,1), transform.rotation);
    }
}
