Question

我有一个相当简单的问题（除了我）...我创建了一个牌手阵列，我想按照hierchy中出现的顺序通过数组访问他们的名字：

例如，在层次结构中显示：

Canvas
   Hand
    card1
    card2
    card3
    card4

我创建了这段代码：

players = GameObject.FindGameObjectsWithTag("Player");
foreach (GameObject go in players)
{
    Debug.Log("Player  " + go + " is named " + go.name);
}

我可以访问卡片手，但顺序错误。有什么建议吗？

永远不要依赖于项FindGameObjectsWithTag返回的顺序，因为这未在文档中指定，并且可能无法预测。您必须添加循环遍历数组的自定义函数，并通过与GameObject.name属性进行比较来查找指定的GameObject。

GameObject[] players;
void test()
{
    players = GameObject.FindGameObjectsWithTag("Player");
    foreach (GameObject go in players)
    {
        Debug.Log("Player " + go + " is named " + go.name);
    }
}

GameObject getGameObject(string gameObjectName)
{
    for (int i = 0; i < players.Length; i++)
    {
        //Return GameObject if the name Matches
        if (players[i].name == gameObjectName)
        {
            return players[i];
        }
    }

    Debug.Log("No GameObject with the name \"" + gameObjectName + "\" found in the array");
    //No Match found, return null
    return null;
}

<强>用法：

GameObject card1 = getGameObject("card1");
GameObject card2 = getGameObject("card2");
GameObject card3 = getGameObject("card3");
GameObject card4 = getGameObject("card4");

修改：

如果你的目标是按顺序对数组中的项进行排序，那么应该这样做：

players = GameObject.FindGameObjectsWithTag("Player"); players = players.OrderBy(c => c.name).ToArray();

按层次结构中的名称访问游戏对象的数组/列表
