The timer starts after a collision with an object

Question

Hello all!

I have a Timer script (C#):

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class Timer : MonoBehaviour {
 
     public Text counterText;
     public bool TimerOn;
 
     public float seconds, minutes;
 
     void Start(){
         TimerOn = false;
         Text counterText = GetComponent<Text>();
         counterText = GetComponent<Text>() as Text;
     }
 
     void Update(){
         if (TimerOn = true){
             minutes = (int)(Time.time / 60f);
             seconds = (int)(Time.time % 60f);
             counterText.text = minutes.ToString("00") + ":" + seconds.ToString("00");
         }
     }
 }

And I want to do when my car will collide with the invisible object, for example, (Box1) is a timer starts running but if a collision with an object (Box2) is the timer will stop working.

Someone would like to help me? It was not until I begin programming with Unity so please bear with us.

*I am using google translator because I come from Polish, and I do not speak much English. :)

You should look up the API for OnTriggerEnter and CompareTag

 void OnTriggerEnter (Collider other) {
      if (other.gameObject.CompareTag("Box1")) {
           TimerOn = true;
      } else if (other.gameObject.CompareTag("Box2")) {
           TimerOn = false;
      }
 }

Create a tag called "Box1" and "Box2" and put it on the two GameObjects that you want to collide with (make sure they have colliders as well)
