Hi! I have A working Inventory system and health system, but I can’t figure out how to make it so the health button regens health here’s my code:

Health:

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

public class Health : MonoBehaviour
{
public int health;
public int numOfHearts;

public Image[] hearts;
public Sprite fullHeart;
public Sprite emptyHeart;

private void Start() { 

}

private void OnTriggerEnter2D(Collider2D other)
{
    if (other.gameObject.CompareTag("Enemy"))
    {
        health -= 1;
    }
}

void Update()
{
    if (health > numOfHearts)
    {
        health = numOfHearts;
    }
    if (health < 1)
    {
        Destroy(this.gameObject);
    }

    for (int i = 0; i < hearts.Length; i++)
    {
        if (i < health)
        {
            hearts*.sprite = fullHeart;*

}
else
{
hearts*.sprite = emptyHeart;*
}
if(i < numOfHearts)
{
hearts*.enabled = true;*
}
else
{
hearts*.enabled = false;*
}
}
}
}
Button:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class HealthButton : MonoBehaviour
{
public GameObject effect;
private Transform player;

void Start()
{
player = GameObject.FindGameObjectWithTag(“Player”).transform;
}

// Update is called once per frame
public void Use()
{
Instantiate(effect, player.position, Quaternion.identity);
Destroy(gameObject);
}
}

make your health script into an instance (so you can access it from a different script) by writing
public static Health instance;

void Awake ()
{
instance=this
}

and then in the use function in the button script add

Health.instance.health++;

which accesses the health scripts variable “health” and adds a heart.

try this
