Time for action – moving the enemy

With a list of patrol locations initialized on Start(), we can grab the enemy NavMeshAgent component and set its first destination.

Update EnemyBehavior with the following code and hit Play:

 // 1
 using UnityEngine.AI;
 
 public class EnemyBehavior : MonoBehaviour 
 {
     public Transform patrolRoute;
     public List<Transform> locations;
 
     // 2
     private int locationIndex = 0;
 
     // 3
     private NavMeshAgent agent;
 
     void Start()
     {
         // 4
         agent = GetComponent<NavMeshAgent>();

         InitializePatrolRoute();
 
         // 5
         MoveToNextPatrolLocation();
     }

     void InitializePatrolRoute() 
     {
          // ... No changes needed ...
     }
 
     void MoveToNextPatrolLocation()
     {
         // 6
         agent.destination = locations[locationIndex].position;
     }
 
     void OnTriggerEnter(Collider other)
     {
         // ... No changes needed ...
     }
 
     void OnTriggerExit(Collider other...
