OnTriggerEnter2D problem?

Hello everyone!
Okay so I have this small project working on, a 2D platformer, I’m still new to unity so this might be a little stupid… Anyways, my problem is that i’m tryiing to make a small code that respawns my player every time he collide with an object with deathObj tag I tried using OnTriggerEnter on another project before and it worked perfectly (3D game) but now it doesn’t seem to work at all. This is the code im using:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerDeath : MonoBehaviour {



	void OnTriggerEnter2D(Collider2D deathObj)
	{
		if (deathObj.gameObject.CompareTag ("deathObj")) {
			Debug.Log("You are dead!");
                       //for now im just trying to print this message in the console but nothing happens.. 
		}
	}
}

Also I’ve set up the tags on unity so that shouldn’t be the problem.
Thanks!

How is your collision matrix set up?

Also, do you have a Rigidbody2D and Collider2D component on your object?

Well that was so stupid of me. I’ve added a collided 2D but forgot the rigidBody2D. Thank you very much! Now its working!
