Hello, i am trying to implement Hitpoints UI for my player, so that everytime my player looses a hitpoint the value should decrement by 1. I have done creating the panel with score. Hereby attached the health script. Please Help

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class HealthScript : MonoBehaviour
 {
 
     public int HitPoints = 1;
     private int score = 1;
     
 
     public bool isEnemy = true;
     
 
     void OnTriggerEnter2D(Collider2D collider)
     {
 
         ShotScript shot = collider.gameObject.GetComponent<ShotScript>();
 
         if (shot != null)
         {
             if (shot.isEnemyShot != isEnemy)
             {
                 
                 HitPoints -= shot.damage;
               
                 Destroy(shot.gameObject);
                 
                 if (HitPoints <= 0)
                 {
                     SpecialEffectsHelper.Instance.Explosion(transform.position);
                     SoundEffectsHelper.Instance.MakeExplosionSound();
                     Score.score += score;
                    Destroy(gameObject);
                     
                 }
             }
         }
     }
 }
