2D COLLISION NOT WORKING WITH TAGS

Question

I am making a 2D game much like Doodle Jump. A bird AI follows the character and changes scene on collision. Although, I do not want the bird changing scene when $$anonymous$$tting the platfroms so I want a script that changes scene when colliding with a gameobject with the tag Player. I have tried many different ways to do t$$anonymous$$s but either it ends up not colliding with anyt$$anonymous$$ng or colliding with everyt$$anonymous$$ng. Please Help!,I am making a 2d game much liked doodle jump but there is a bird ai following the character. I dont want the bird colliding with the platforms though but I am unsure how to make it so the bird only kills me if it collides with a gameobject with the tag Player. I have tried many different ways but either the bird collides with everyt$$anonymous$$ng or collides with not$$anonymous$$ng. Please help.

Hmm have you tried adding a Rigidbody2D component to the bird or the player? Can I at least see your code so I can determine where the problem is

@MATEOICHIJO The bird and the player both have box collider 2d and rigidbody 2d, the bird is a trigger, here is the brid ai code =

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

[RequireComponent(typeof(Rigidbody2D))] public class EnemyAI : MonoBehaviour {

 public Transform target;

 public float speed = 5f;
 public float rotateSpeed = 200f;

 private Rigidbody2D rb;

 // Use t$$anonymous$$s for initialization
 void Start()
 {
     rb = GetComponent<Rigidbody2D>();
 }

 void FixedUpdate()
 {
     Vector2 direction = (Vector2)target.position - rb.position;

     direction.Normalize();

     float rotateAmount = Vector3.Cross(direction, transform.up).z;

     rb.angularVelocity = -rotateAmount * rotateSpeed;

     rb.velocity = transform.up * speed;
 }


 void OnCollisionEnter2D(Collision2D col)
 {
     if (col.gameObject.tag == "Player")
     {
         Destroy(col.gameObject);
     }
 }

}

Have you tried Destroy(other.gameObject)?
