Switch to Manual
public static GameObject[] FindGameObjectsWithTag(string tag);

Parameters

tag The name of the tag to search GameObjects for.

Description

Returns an array of active GameObjects tagged tag. Returns empty array if no GameObject was found.

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.

// Instantiates respawnPrefab at the location
// of all game objects tagged "Respawn".

using UnityEngine; using System.Collections;

public class ExampleClass : MonoBehaviour { public GameObject respawnPrefab; public GameObject[] respawns; void Start() { if (respawns == null) respawns = GameObject.FindGameObjectsWithTag("Respawn");

foreach (GameObject respawn in respawns) { Instantiate(respawnPrefab, respawn.transform.position, respawn.transform.rotation); } } }

Another example:

// Find the name of the closest enemy

using UnityEngine; using System.Collections;

public class ExampleClass : MonoBehaviour { public GameObject FindClosestEnemy() { GameObject[] gos; gos = GameObject.FindGameObjectsWithTag("Enemy"); GameObject closest = null; float distance = Mathf.Infinity; Vector3 position = transform.position; foreach (GameObject go in gos) { Vector3 diff = go.transform.position - position; float curDistance = diff.sqrMagnitude; if (curDistance < distance) { closest = go; distance = curDistance; } } return closest; } }

Another example, testing for empty array:

using UnityEngine;

// Search for game objects with a tag that is not used

public class Example : MonoBehaviour { void Start() { GameObject[] gameObjects; gameObjects = GameObject.FindGameObjectsWithTag("Enemy");

if (gameObjects.Length == 0) { Debug.Log("No game objects are tagged with 'Enemy'"); } } }
