JavaScript => static function FindWithTag(tag: string): GameObject;
C# => static GameObject FindWithTag(string tag);

Parameters 参数

tag	The tag to search for. 要搜索的标签

Description 描述

Returns one active GameObject tagged /tag/. Returns null if no GameObject was found.

返回标记为tag的一个游戏对象，如果没有找到对象则为空。

Tags must be declared in the tag manager before using them. A UnityException will be thrown if the tag does not exist or an empty string or null is passed as the tag.

标签必须在使用之前到标签管理器里面声明。如果标签不存在或为空字符串或传递null作为标签，将抛出Unity异常。

JavaScript:

	var respawnPrefab : GameObject;
	var respawn: GameObject;
 
	// Instantiates respawnPrefab at the location 
	// of the game object with tag "Respawn"
     // This example assumes that a game object is tagged with "Respawn"
	function Start()
	{
		if (respawn==null)
			respawn = GameObject.FindWithTag ("Respawn");
		Instantiate (respawnPrefab, respawn.transform.position, respawn.transform.rotation);
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public GameObject respawnPrefab;
    public GameObject respawn;
    void Start() {
        if (respawn == null)
            respawn = GameObject.FindWithTag("Respawn");
 
        Instantiate(respawnPrefab, respawn.transform.position, respawn.transform.rotation) as GameObject;
    }
}
