GameObject.Find 查找

# [GameObject](GameObject.html).Find 查找

static function *Find* (*name* : string) : GameObject

*Description* 描述

Finds a game object by name and returns it.

If no game object with name can be found, null is returned. If name contains
a '/' character it will traverse the hierarchy like a path name. This function
only returns active gameobjects.

找到并返回一个名字为 name 的游戏物体。

如果以 name 为名字的游戏物体没有被找到，则返回空.如果 name 中包含'/'字符，这个名称将被视作一个 hierarchy 中的路径名.这个函数只返回活动的游戏物体。

For performance reasons it is recommended to not use this function every
frame Instead cache the result in a member variable at startup or use
GameObject.FindWithTag.

除非迫不得已，建议不要在每一帧中使用这个函数。可以在开始的时候用一个成员变量来缓存结果或者使用 GameObject.FindWithTag 函数。

```
using UnityEngine;
using System.Collections;

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

```
var hand : GameObject;
// This will return the game object named Hand in the scene.
//这将返回名为Hand 的游戏物体
hand = GameObject.Find("Hand");

// This will return the game object named Hand.
// Hand may not have a parent in the hierarchy view!
//这将返回名为Hand 的游戏物体，在层次视图中hand也没有父级物体
hand = GameObject.Find("/Hand");

// This will return the game object named Hand,
// which is a child of Arm -> Monster.
// Monster may not have a parent in the hierarchy view!
//这将返回Monster/Arm 的子级下名为Hand 的游戏物体，在层次视图中Monster也没有父级物体
hand = GameObject.Find("/Monster/Arm/Hand");

// This will return the game object named Hand,
// which is a child of Arm -> Monster.
// Monster may have a parent.
//这将返回Monster/Arm 的子级下名为Hand 的游戏物体，在层次视图中Monster可以有父级物体
hand = GameObject.Find("Monster/Arm/Hand");
```

This function is most useful to automatically connect references to other
objects at load time, eg. inside MonoBehaviour.Awake or MonoBehaviour.Start. You
should avoid calling this function every frame eg. MonoBehaviour.Update for
performance reasons. A common pattern is to assign a game object to a variable
inside MonoBehaviour.Start. And use the variable in MonoBehaviour.Update.

这个函数多用于在加载时自动连接其他物体.比如在 MonoBehaviour 函数中或者在 MonoBehaviour.Start 中使用.你应该避免在每一帧中使用这个函数,比如在 MonoBehaviour.Update 中使用.一个通用模式是在 MonoBehaviour.Start 中用一个变量来保存一个游戏物体，然后在 MonoBehaviour.Updata 中使用它.

public class example : MonoBehaviour {
	private GameObject hand;
	void Start() {
		hand = GameObject.Find("/Monster/Arm/Hand");
	}
	void Update() {
		hand.transform.Rotate(0, 100 * Time.deltaTime, 0);
	}
}
```

```
// Find the hand inside Start and rotate it every frame
//在Start里查找hand物体，并在每帧旋转它
private var hand : GameObject;
function Start () {
	hand = GameObject.Find("/Monster/Arm/Hand");
}

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