Problem: trigger within object

Question

Hello! I'm new to programming, so I searched a lot, and I tried to modify some scripts, but all failed. It has been a week. But I didn't find the answer.

The problem is: I have a cone. This cone is a child to the player. It's likely a flash light and I need an enemy to run away if it is trapped in the cone (the light), but after it leaves light spot, I want it to go after me again. I don't know exactly what to do. Here is the script:

 public class EnemyMovement : MonoBehaviour
 {
     Transform player;
     NavMeshAgent nav;
     public float fieldOfViewAngle = 45f;
     public bool FlashLight;
 
 
     void Awake ()
     {
         player = GameObject.FindGameObjectWithTag ("Player").transform;
         nav = GetComponent <NavMeshAgent> ();
     }
         
 
     void Update ()
     {
             nav.SetDestination (player.position);
     }
 
 
     void OnTriggerStay ()
     {
     }
 
 
     void OnTriggerExit ()
     {
     }
 }

Thanks a lot

Try this unntested scripts:

 public class enemyController : MonoBehaviour 
 {
     Transform player;
     public bool flashLight = false;
     private float speed = 0.5f;
     // Use this for initialization
     void Start () 
     {
         
     }
     
     // Update is called once per frame
     void Update () 
     {
         transform.LookAt(player);
 
         if(flashLight)
         {
             transform.position += transform.forward*speed*Time.deltaTime*-1;
         }
         else
         {
             transform.position += new Vector3(player.position.x, player.position.y, player.position.z);
         }
     }
 }

and in the playerController script:

 public class playerController : MonoBehaviour 
 {
     enemyController control = new enemyController();
     public Light point;
 
     Ray ray;
     RaycastHit hit;
     // Use this for initialization
     void Start () 
     {
     }
     
     // Update is called once per frame
     void Update () 
     {
         if(Physics.Raycast(ray, out hit))
         {
             if(hit.transform.tag == "Enemy")
             {
                 control.flashLight = true;
             }
         }
     }
 }
