Transform.Find

Parámetros

Valor de retorno

Transform The returned child transform or null if no child is found.

Descripción

Finds a child by n and returns it.

If no child with n can be found, null is returned. If n contains a '/' character it will access the Transform in the hierarchy like a path name.

Note: Find does not perform a recursive descend down a Transform hierarchy.

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");
    }
}

As described Find does not descend the Transform. Find will only search the given list of children looking for a named Transform.


A GameObject with three children. Find() does not find the third child.

// 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");
        }
    }
}
