How do I make enemies stay away from other enemies?

I am making an endless shooter and I just can’t figure out how to make the enemies stay away from other enemies. Here is my script that makes the enemy find the player, then attacks it:

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

public class EnemyAI : MonoBehaviour
{
    
    public float AIspeed;
    public Transform AItarget;

    void Start()
    {
     AItarget = GameObject.FindGameObjectWithTag("Player").GetComponent<Transform>();
     int rand = Random.Range(2, 5);
     AIspeed = rand;
    }

    
    void Update()
    {
        transform.position = Vector3.MoveTowards(transform.position, AItarget.position, AIspeed * Time.deltaTime);
    }
}

Thanks!

Ok, I found a solution (after 4 days of messing around in the engine, mind you):

  1. On the Enemy Gameobject (or any other GameObject that you don’t want colliding with others of its kind), make an Empty Gameobject and child it to the Enemy Gameobject.
  2. Add a Box Collider 2D component to the Empty Gameobject.
  3. Adjust the collider to what you want.
  4. Make a new layer for the Empty Gameobject.
  5. Go to Edit (at the top right of your screen) > Project Settings > Physics2D > Collision Matrix
  6. From here, make sure nothing collides with the Empty Gameobject layer except the Enemy Gameobject and itself.
  7. If you think the Enemy Gameobjects are staying a little too far away from each other, make the Empty Gameobject’s Box Collider2D smaller; vice versa.
  8. Done!

Please note that this is probably a very bad and inefficient method of doing this but this is the only way I could think of :confused:
