killzone not detecting player

Questions & Answers
1

I want an invisible cube that kills the player if the player touches it. the player runs on a player controller, using a script called walk.cs, has 3f health and the process used to lower said health is ddamage

I set the cube so it has no renderer, and added the trigger tag to the cube collider, but its not even printing “pão” like I asked it to, which means it isnt even detecting the collision

also, I have tried using OnControllerColliderHit, but it didnt work either

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class killzone : MonoBehaviour
{
    void OnCollisionEnter(Collision col)
    {
        if(col.gameObject.tag == ("Player"))
        {
            print("pão");
            walk target = col.transform.GetComponent<walk>();
            target.ddamage(3f);
        }
    }
}

OnCollision, as well as OnTrigger messages, are called by game objects with a rigidbody attached, respectively OnControllerColliderHit is called for game objects with a character controller. Make sure you have either and you’ll be good.
