Need help making my AI stop following its destination

Hey!
So basically I am trying to make a car game and I am currently working on the AI. I applied a script to the AI which can detect the playercar. I also used a waypointsystem and made the AI follow it. However, I also wish to make the AI stop following the waypointsystem when detecting the player car, but I am uncertain on how.

This is the script I am currently working on:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.AI;
5.  
6. public class NPC : MonoBehaviour
7. {
8.     [HideInInspector] public AISensor sensor; // This is the code for the sensor which I can provide if necessary
9.  
10.     public GameObject destinationPoint;
11.     NavMeshAgent theAgent;
12.     GameObject brakes;
13.  
14.  
15.     void Start()
16.     {
17.         sensor = GetComponent<AISensor>();
18.         theAgent = GetComponent<NavMeshAgent>();
19.     }
20.  
21.     void Update()
22.     {
23.         theAgent.SetDestination(destinationPoint.transform.position); // This is to make the AI follow the waypointsystem
24.     }
25.     public void Update(NPC npc)
26.     {
27.         if (!brakes)
28.         {
29.             brakes = FindPickUp(npc);
30.  
31.             if (brakes)
32.             {
33.                  = false;  // I don't know what to add in front of false
34.             }
35.         }
36.     }
37.  
38.     GameObject FindPickUp(NPC npc)
39.     {
40.         if (npc.sensor.Objects.Count > 0)
41.         {
42.             return npc.sensor.Objects[0];
43.         }
44.         return null;
45.     }
46. }

 

I appreciate all suggestions and tips, and I can provide more information if needed

 

Can you not just set a new destination or disable the NavMeshAgent?

 

Yea, I will try to set a new destination, cuz then I can also chose where it goes
