How to kill enemy when the bullet hits the BoxColllider2D?

Questions & Answers

Hello!
I´m currently working in a game and I´m having trouble here. My enemy has two colliders (BoxCollider2D and CircleCollider2D). I use the CircleCollider2D to trigger the enemy (if the player is inside of the CircleCollider2D, the enemy will attack him). I knew that if my player shoots, bullet will collide with the CircleCollider2D first. I´m having trouble cause I only want to apply damage when the bullet hits the BoxCollider2D.
Can you help me solve this?

Here´s my code:

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

public class Bullet : MonoBehaviour {

public float vel = 5f;

Rigidbody2D rb;
BoxCollider2D enemyhit;

// Use this for initialization
void Start () {
	rb = GetComponent<Rigidbody2D>();
}

// Update is called once per frame
void Update () {
	print ("oribullet:" + transform.rotation.z);
	if (transform.rotation.z !=-1){
		rb.AddForce (Vector2.right * vel);	
	}else{
		rb.AddForce (-Vector2.right * vel);	
	}

	}

void OnTriggerEnter2D(Collider2D other)
{
	if (other.gameObject.tag == "bomber") 
	{	
			DestroyObject (other.gameObject);
			Destroy (gameObject);
	}
}

}

Your CircleCollider2D should be a trigger, not a physically blocking collider, and your BoxCollider2D should be a non-trigger collider. Then you can detect if the player entered the range in OnTriggerEnter(Collider), and detect if it was shot in OnCollisionEnter(Collision).
