public string tag ;


The tag of this GameObject.

A tag can be used to identify a GameObject. Tags must be declared in the Tags and Layers manager before using them.

**注意:**您不应通过 Awake()OnValidate() 方法设置标签。这是因为组件唤醒的顺序是不确定的,因此可能导致意外行为,例如标签在唤醒时被覆盖。如果尝试执行此操作,Unity 将生成一条警告:“SendMessage cannot be called during Awake, CheckConsistency, or OnValidate”。

using UnityEngine;

public class Example : MonoBehaviour { void Start() { //Set the tag of this GameObject to Player gameObject.tag = "Player"; }

private void OnTriggerEnter(Collider other) { //Check to see if the tag on the collider is equal to Enemy if (other.tag == "Enemy") { Debug.Log("Triggered by Enemy"); } } }
