Enemy follow a target but keeping distance between them

Questions & Answers
1

I have 3 enemies vehicles following my hero but because my hero is moving in a circular path the 3 enemies get progressively together and I need them to keep the distance between them. I tried setting and offset based on the initial position but again as the movement is circular what in the beginning is an x offset becomes a z offset and vice versa.

this is the code for the enemy movement:

public class SmallEnemyMovAI : MonoBehaviour
    {
        public GameObject heroTarget;
        private float speed = 3;
        bool finished = false;
        Vector3 offset;
        void Start()
        {
            offset = this.transform.position - heroTarget.transform.position;
        }
    
        // Update is called once per frame
        void Update()
        {
            if (!finished)
            {
                this.transform.Translate(Vector3.forward * speed * Time.deltaTime);
                Vector3 vec = hero.transform.position - offset;
              
                transform.LookAt(vec);
            }
               
        }    
       
    }

And this is the hero movement:

public class BigBoatMovAI : MonoBehaviour
{
    public GameObject target;

    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {      
        transform.RotateAround(target.transform.position, Vector3.up, -0.5f * Time.deltaTime);
    }
}

i would make an edit to the script that spawns the enemies. create a list of gameobjects, and when each is created, add it to the list.on each frame, for each enemy, check if they are colliding with any of the others, and if they are, move both a small distance away from each other.
