GameObject.Find

Description

按 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。

Note: If you wish to find a child GameObject, it is often easier to use Transform.Find.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public GameObject hand;
    void Example() {
        hand = GameObject.Find("Hand");
        hand = GameObject.Find("/Hand");
        hand = GameObject.Find("/Monster/Arm/Hand");
        hand = GameObject.Find("Monster/Arm/Hand");
    }
}

GameObject.Find is useful for automatically connecting references to other objects at load time; for example, inside MonoBehaviour.Awake or MonoBehaviour.Start.

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;

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);
    }
}
