Question

是否可以从父级获取游戏对象嵌套子项？

地图Gameobject如下所示：

ListProcess (ListProcessItem1) => item1 => 1 => ItemIcon

例如Iam使用此代码：

itemslot = GameObject.FindGameObjectWithTag ("ListProcessItem1").gameObject;
GameObject item = itemslot.gameObject.transform.GetChild(0).gameObject;
GameObject child = item.gameObject.transform.GetChild(0).gameObject;
GameObject sitemImage = child.gameObject.transform.GetChild(0).gameObject;

当我运行代码时出现错误：

UnityException: Transform child out of bounds
LakeMainProcess.generatePrize1 () (at Assets/script/fishing/LakeMainProcess.cs:48)
LakeMainProcess.Start () (at Assets/script/fishing/LakeMainProcess.cs:21)

注意：我只能到达游戏对象（1）。游戏对象（ItemIcon）出错。

我该如何解决？

用这个替换你的块：

Debug.Log("A " + GameObject.FindGameObjectWithTag ("ListProcessItem1") == null);
var itemslot = GameObject.FindGameObjectWithTag ("ListProcessItem1").gameObject;

Debug.Log("B " + itemslot.gameObject.transform.GetChild(0) == null);
GameObject item = itemslot.gameObject.transform.GetChild(0).gameObject;

Debug.Log("C " + item.gameObject.transform.GetChild(0) == null);
GameObject child = item.gameObject.transform.GetChild(0).gameObject;

Debug.Log("D " + child.gameObject.transform.GetChild(0) == null);
GameObject sitemImage = child.gameObject.transform.GetChild(0).gameObject;

它会告诉你哪些对象无法找到。我打赌它是FindGameObjectWithTag，你确定这个对象有这个确切的标签吗？

或者更简单地使用：

var ico = GameObject.FindGameObjectWithTag("ListProcessItem1").transform.FindChild("item1/1/ItemIcon").GetComponent<WhateverYouNeed>();

是否可以通过脚本从父级获取gameobject嵌套子级？
