public static GameObject Find (string name);

Description

name 查找 GameObject,然后返回它。

此函数仅返回活动 GameObject。如果未找到具有 name 的 GameObject,则返回 null。如果 name 包含“/”字符,则会向路径名称那样遍历此层级视图。

出于性能原因,建议不要每帧都使用此函数,而是在启动时将结果缓存到成员变量中,或者使用 GameObject.FindWithTag

注意:如果您要查找子 GameObject,使用 Transform.Find 通常会更加轻松。

注意:如果正在使用多个场景运行此游戏,则 Find 将在所有这些场景中进行搜索。

using UnityEngine;
using System.Collections;

// This returns the GameObject named Hand in one of the Scenes.

public class ExampleClass : MonoBehaviour { public GameObject hand;

void Example() { // This returns the GameObject named Hand. hand = GameObject.Find("Hand");

// This returns the GameObject named Hand. // Hand must not have a parent in the Hierarchy view. hand = GameObject.Find("/Hand");

// This returns the GameObject named Hand, // which is a child of Arm > Monster. // Monster must not have a parent in the Hierarchy view. hand = GameObject.Find("/Monster/Arm/Hand");

// This returns the GameObject named Hand, // which is a child of Arm > Monster. hand = GameObject.Find("Monster/Arm/Hand"); } }

GameObject.Find 有助于在加载时自动连接对其他对象的引用;例如在 MonoBehaviour.AwakeMonoBehaviour.Start 内。

出于性能原因,建议不要每帧都使用此函数。

A common pattern is to assign a GameObject to a variable inside MonoBehaviour.Start, and use the variable in MonoBehaviour.Update.

using UnityEngine;
using System.Collections;

// Find the GameObject named Hand and rotate it every frame

public class ExampleClass : MonoBehaviour { private GameObject hand;

void Start() { hand = GameObject.Find("/Monster/Arm/Hand"); }

void Update() { hand.transform.Rotate(0, 100 * Time.deltaTime, 0); } }
