Need help whit me script pls

I would like to make an object add X amount of life to my character, but I don't understand how to do it. I am a newbie on the subject of development and programming

Code (CSharp):

1. public class VidaExtra : MonoBehaviour
2. {
3.     public int CantidadDeVida;
4.  
5.     Health Vida;
6.  
7.  
8.     private void Awake()
9.     {
10.  
11.         Vida = GetComponent<Health>();
12.  
13.     }
14.  
15.     void OnTriggerEnter(Collider other)
16.     {
17.         if (other.CompareTag("Player"))
18.         {
19.             Vida.currenthealth =++ CantidadDeVida;
20.  
21.         }
22.  
23.     }
24. }

Code (CSharp):

1. public class Health : MonoBehaviour
2. {
3.     public int startinghealth = 100;
4.     public int currenthealth;
5.     public Slider healthSlider;
6.     public Image damageImage;
7.     public float flashspeed = 5f;
8.     public Color flashcolor = new Color(1f, 0f, 0f, 0.1f);
9.  
10.     public GameObject PersonajeVivo;
11.     public GameObject PersonajeMuerto;
12.     public Animator AnimaiconMuerte;

My advice is to keep watching AND following tutorials. If you want to learn the method how to implement powerups/objects you can pick up, you can do like this:

Otherwise on the forums we are eager to help if you put your own effort into it and start to develop it. If you stuck somewhere, you can post what you have done so far and what's your problem. We will help, but we can't make an entire feature for you and I think a forum post is not the best tool to write an entire tutorial just for you how to do an entire feature.
