so below is my field of view script I'm looking to idea how make the enemy chase you if you're in the field of view

 using System;
 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class FieldOfView : MonoBehaviour
 {
     public float radius;
     [Range(0,360)]
     public float angle;
 
     public GameObject playerRef;
 
     public LayerMask targetMask;
     public LayerMask obstructionMask;
 
     public bool canSeePlayer;
 
     private void Start()
     {
         playerRef = GameObject.FindGameObjectWithTag("Player");
         StartCoroutine(FOVRoutine());
     }
 
     private IEnumerator FOVRoutine()
     {
         WaitForSeconds wait = new WaitForSeconds(0.2f);
 
         w$$anonymous$$le (true)
         {
             yield return wait;
             FieldOfViewCheck();
         }
     }
 
     private void FieldOfViewCheck()
     {
         Collider[] rangeChecks = Physics.OverlapSphere(transform.position, radius, targetMask);
 
         if (rangeChecks.Length != 0)
         {
             Transform target = rangeChecks[0].transform;
             Vector3 directionToTarget = (target.position - transform.position).normalized;
 
             if (Vector3.Angle(transform.forward, directionToTarget) < angle / 2)
             {
                 float distanceToTarget = Vector3.Distance(transform.position, target.position);
 
                 if (!Physics.Raycast(transform.position, directionToTarget, distanceToTarget, obstructionMask))
                 {
                       canSeePlayer = true;
                       print("INTERACTED WITH" + gameObject.name);
                 }
                 else
                 {
                     canSeePlayer = false;
                 }      
             }
             else
             {
                 canSeePlayer = false;
             }
         }
         else if (canSeePlayer)
         {
             canSeePlayer = false;
         }
     }
