Do something like this: using System.Collections; using System.Collections.Generic; using UnityEngine;

 public class AttackerSpawner : MonoBehaviour
 {
     [SerializeField] float minSpawnDelay = 1f;
     [SerializeField] float maxSpawnDelay = 5f;
     [SerializeField] Attacker[] attackerPrefabArray;
     [SerializeField] float spawnerDelay = 1f;
     [SerializeField] float timeToWait = 10f;
     private float timer;
     
 
     bool spawn = true;
 
     IEnumerator Start()
     {
         timer = Time.time + timeToWait;
 
 
         yield return new WaitForSeconds(spawnerDelay);
         while (spawn)
         {
             yield return new WaitForSeconds(Random.Range(minSpawnDelay, maxSpawnDelay));
             SpawnAttacker();
         }
 
     }
 
     public void Update()
     {
         if (Time.time > timer)
         {
             StopSpawning();
         }
     }
 
     public void StopSpawning()
     {
         spawn = false;
     }
     private void SpawnAttacker()
     {
         var attackerIndex = Random.Range(0, attackerPrefabArray.Length);
         Spawn(attackerPrefabArray[attackerIndex]);
     }
     private void Spawn(Attacker myAttacker)
     {
         Attacker newAttacker = Instantiate
             (myAttacker, transform.position, transform.rotation)
             as Attacker;
         newAttacker.transform.parent = transform;
     }
 }
