Transform.Find

参数

返回

Transform 如果找到子项，则返回该子变换；否则返回 null。

描述

按 n 查找子项，然后返回它。

如果未找到具有 n 的子项，则返回 null。 如果 n 包含“/”字符，它将像访问路径名称那样访问层级视图中的变换。

__注意：__.Find 不在变换层级视图中执行递归向下查找。

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public GameObject player;
    public GameObject gun;
    public Transform ammo;

    //Invoked when a button is clicked.
    public void Example()
    {
        //Finds and assigns the child of the player named "Gun".
        gun = player.transform.Find("Gun").gameObject;

        //If the child was found.
        if (gun != null)
        {
            //Find the child named "ammo" of the gameobject "magazine" (magazine is a child of "gun").
            ammo = gun.transform.Find("magazine/ammo");
        }
        else Debug.Log("No child with the name 'Gun' attached to the player");
    }
}

如上所述，Find 不在 Transform 中向下查找。Find 将只搜索给定的子项列表，以查找名为 Transform 的子项。

\ 附带三个子项的一个游戏对象。Find() 不能找到第三个子项。

// ExampleClass has a GameObject with three spheres attached.
// Two of these are children of the GameObject.  The third
// transform, sphere3, is a child of sphere2.  Find() does
// not find this child.

using UnityEngine;

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        Transform result = gameObject.transform.Find("sphere3");

        if (result)
        {
            Debug.Log("Found sphere3");
        }
        else
        {
            Debug.Log("Did not find sphere3");
        }
    }
}
