Remarks

A tag can be used to identify a GameObject. Tags must be declared in the Tags and Layers manager before using them.
Note: Do not set a tag from Awake() or OnValidate(). The order in which 
Awake
is called is not deterministic between components and a tag can be overwritten when its 
Awake
is called. If you do this, Unity generates the warning 
SendMessage cannot be called during Awake, CheckConsistency, or OnValidate
.
The example below sets the current GameObject's tag to "Player" and then implements MonoBehaviour.OnTriggerEnter(Collider) to check if the Collider on the other object involved in a collision with this object is tagged "Enemy".
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 if the collider of the other GameObject involved in the collision is tagged "Enemy"        if (other.tag == "Enemy")        {            Debug.Log("Triggered by Enemy");        }    }}
