I need help with the player's health points

Question

(I'm sorry if my writing sounds weird. I hope it's coherent enough to get my point across.) I was following a tutorial by BlackThornProd for hearts to represent the players health instead of using a health bar. The problem I'm having is that I'm not sure how to make it so that when the player collides with an enemy that they lose a heart.

Health Script: {

 public int health;
 public int numOfHearts;

 public Image[] hearts;
 public Sprite fullHeart;
 public Sprite emptyHeart;
 // Start is called before the first frame update
 void Start()
 {
     
 }

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

     if (health > numOfHearts)
     {
         health = numOfHearts;
     }
     for (int i = 0; i < hearts.Length; i++)
     {

         if(i < health)
         {
             hearts[i].sprite = fullHeart;
         }

         else
         {
             hearts[i].sprite = emptyHeart;
         }
         if(i < numOfHearts)
         {
             hearts[i].enabled = true;
         }

         else
         {
             hearts[i].enabled = false;
         }
     }
 }

 void OnCollisionEnter2D(Collision2D col)
 {
     if (col.gameObject.tag == "Enemy")
     {
         //I'm not sure what to put here.
     }
 }

}

If you need anymore information, let me know. Thank you.

It seems like all you would need to do is subtract 1 health.

 void OnCollisionEnter2D(Collision2D col)
  {
      if (col.gameObject.tag == "Enemy")
      {
          health -= 1;
          Debug.Log("Enemy Collision Detected");
      }
  }

If that does not work then make sure you get the "Enemy Collision Detected" message. If you do not then there is a problem with the collision detection. If it works you can remove Debug.Log("Enemy Collision Detected");

Thank you so much! I knew it was a simple solution, but for the life of me I couldn't remember.
