My question is how to give a newly made prefab a location target.

By this I mean, I have made a prefab of an enemy. I don't know how to tell him where his target is because I can't drag it across to him in the menu screen because he is a prefab and if I create him, I can't make it a get component location either because the enemy doesn't know which one I am talking about. So it comes back to the first problem. I do not know how to get him the target at first. Once he gets the target it works fine. Thanks for to anyone who can fix this issue. I also commented the part where the issue is

using Pathfinding; using UnityEngine; using System.Collections;

[RequireComponent(typeof(Rigidbody2D))] [RequireComponent(typeof(Seeker))] public class EnemyAI : MonoBehaviour { // what to chase public Transform target; // the player // how many times will it check each second to update the path. public float updateRate = 2f; // how often it checks //caching private Seeker seeker; // the finding scirpt private Rigidbody2D rb; // rigidbody 2d. Pretty east

 // The calcualted path
 public Path path;

 // The A.I's speed per second; 
 public float speed = 300f;
 public ForceMode2D fmode;
 public Transform hero; 
 public Transform HomeBase;
 public int currenthealth; 

 [HideInInspector]
 public  bool PathIsEnded = false;

// the max distance from the A.I to a waypoint for it continue to the next way point. public float NextWayPointDistance = 3; // the way point we are currently moving to. private int currentWayPoint = 0;

  void Start()
 {
     currenthealth = GetComponent<Enemy>().health; 
     seeker = GetComponent<Seeker>();
     rb = GetComponent<Rigidbody2D>();
     if (hero == null)
     {
       //  hero.transform.position = 
     }
     if (HomeBase == null)
     {

        // HomeBase.transform.position =
     }

     if(target == null)
     {

         return; 
     }
     // start a new path to the target postion. returning the result to the OnPathComplete method
     seeker.StartPath(transform.position, target.position, OnPathComplete);
     target = HomeBase; 
   StartCoroutine(UpdatePath ()); 
 }

IEnumerator UpdatePath() { if (target == null) {

         yield return false;
     }

     seeker.StartPath(transform.position, target.position, OnPathComplete);
     yield return new WaitForSeconds(1f / updateRate );
     StartCoroutine(UpdatePath());
 }

 IEnumerator UpdateTarget()
 {
     if(target = hero)
     {
         yield return new WaitForSeconds(5f);
         target = HomeBase; 
     }

 }



 public void OnPathComplete (Path p)
 {
    // Debug.Log("We got a path. Did it have an error? " + p.error); 
     if (!p.error)
     {
         path = p;
         currentWayPoint = 0; 
     }
 }

  void FixedUpdate()
 {
     if(GetComponent<Enemy>().health < currenthealth)
     {
         target = hero; 
          
     }
     if (hero == null)
     {
         target = HomeBase; 
     }
     if (target == null)// checks to see if target is null 
     {

         return;
     } 
     if (path == null)// checks to see if target is null
     {
         return; 
     }
     if(currentWayPoint >= path.vectorPath.Count) // tell us if we have reached our target yet
     {
         if (PathIsEnded)
         {
             return;
         }

         
         PathIsEnded = true;
         return; 
     }
     PathIsEnded = false;
     // directions to the next way point
     Vector3 dir = path.vectorPath[currentWayPoint] - transform.position; // gives us a path to go to. The player to the enemy where the enemy will follow the player.
     dir *= speed * Time.fixedDeltaTime;

     // move the A.I

     rb.AddForce(dir, fmode);

     float dist = Vector3.Distance(transform.position, path.vectorPath[currentWayPoint]); 

     if (dist < NextWayPointDistance)
     {
         currentWayPoint++;
         return; 
     }
 }
