when i collide with npc he keeps walking.

so i have a waypoint script on npc's. i also have some kind of dialogue what pops when i hit "e". when i do this on a moving npc he keeps walking. i tried certain things but can't get him to stop....

the collider itself is working, because i do get my camerascript to stop on collision and the text "press E to interract" appears.

any advice would be awesome!!

here is my waypoint script :

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class WaypointSystem : MonoBehaviour {

 public GameObject[] Waypoints;
 public int num = 0;

 public float minDist;
 public float speed;


 public bool rand = false;
 public bool go = true;

 public Animator anim;


 // Start is called before the first frame update
 void Start()
 {
     anim = GetComponent<Animator>();
 }

 // Update is called once per frame
 void Update()
 {

     float dist = Vector3.Distance(gameObject.transform.position, Waypoints[num].transform.position);
   
     if (go)
     {
         if (dist > minDist)
         {
             Move();
         }
         else
         {
             if (!rand) {
                 if (num + 1 == Waypoints.Length)
                 {
                     num = 0;
                 }
                 else
                 {
                     num++;
                 }
             } else
             {
                 num = Random.Range(0, Waypoints.Length);
             }
          
         }
     }
 }


 public void Move()
 {
     anim.SetFloat("speed", speed);
     gameObject.transform.LookAt(Waypoints[num].transform.position);
     gameObject.transform.position += gameObject.transform.forward * speed * Time.deltaTime;
 }

}

i already have a script where i disable certain things, but not the movenement :

using System.Collections; using System.Collections.Generic; using TMPro; using UnityEngine; using UnityEngine.UI;

public class DialogueAppear : MonoBehaviour {

 //[SerializeField] private Canvas customCanvas;
 public GameObject cam;
 public Text text;
 public GameObject walk;
 

 void OnTriggerEnter(Collider other)
 {
     if (other.CompareTag("NPC"))
     {
      //   customCanvas.enabled = true;
         cam.GetComponent<CameraControl>().enabled = false;
         text.enabled = true;
         walk.GetComponent<WaypointSystem>().enabled = false;

     }
 }

 void OnTriggerExit(Collider other)
 {
     if (other.CompareTag("NPC"))
     {
       //  customCanvas.enabled = false;
         cam.GetComponent<CameraControl>().enabled = true;
         text.enabled = false;
         walk.GetComponent<WaypointSystem>().enabled = true;

     }
 }

}

New programmer here! any advice would be much appreciated :D sorry for the long read
