Why is OnTriggerEnter2D not responding in Unity?

Question

Unity

Help me please!
I'm making a 2D game about a spaceship, there are rocks that the ship has to destroy. For some reason, the stone does not react to bullets and a barrier (they have the "Destory" tag). Here is the stone code:

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

public class Control_Stoun : MonoBehaviour {

    void Update () {
    transform.position = new Vector2(transform.position.x, transform.position.y + -1 * 2 * Time.deltaTime);
    transform.Rotate(transform.rotation.x, transform.rotation.y, transform.rotation.z + -1 * 40 * Time.deltaTime);
  }

  private void OnTriggerEnter2D(Collider2D collision)
  {
    Debug.Log("1");
    if (collision.tag == "Destory"){
      Destroy(gameObject);
    }
  }
}

Here are the ingredients of the stone:

Answer 1

1. The trigger must have the is trigger flag
2. To compare the tag, there is a collision.compairTag function. It's faster and doesn't clog memory.
3. One of the objects seems to be rigidbody
Yes, and better than checking tags, adjust the interaction of physics by layers.
