Time for action – referencing the patrol locations 

Now that we understand the basics of procedural programming, it's time to get a reference to our patrol locations and assign them to a usable list:

1. Add the following code to EnemyBehavior:

public class EnemyBehavior : MonoBehaviour 
 {
     // 1
     public Transform patrolRoute;
 
     // 2
     public List<Transform> locations;

             // 6
             locations.Add(child);
         }
     }
 
     void OnTriggerEnter(Collider other)
     {
         // ... No changes needed ...
     }
 
     void OnTriggerExit(Collider other)
     {
         // ... No changes needed ...
     }
 } 

2. Select Enemy and drag the Patrol Route object from the Hierarchy window onto the Patrol Route variable in EnemyBehavior:
