Some help please

Hi, I need help with my plugin. It shoulds work but additions and subtractions in integers not works correctly.
Here is my code, thanks

Code:

  @EventHandler
  public void alClickearElInventario(InventoryClickEvent e) {
     File f1 = new File("plugins/LutorRPG/jugadores/" + e.getWhoClicked().getName() + ".yml");
     FileConfiguration f2 = YamlConfiguration.loadConfiguration(f1);
    
     int pt = f2.getInt("Puntos_Disponibles");
     int nv = f2.getInt("Nivel");
     int f = f2.getInt("Fuerza");
     int d = f2.getInt("Defensa");
     int a = f2.getInt("Agilidad");
     int i = f2.getInt("Inteligencia");
     int dz = f2.getInt("Destreza");
    
    Player p = (Player)e.getWhoClicked();
   
    if (e.getInventory().getName().equals(inv1.getName())) {
        e.setCancelled(true);
       
    if (e.getCurrentItem() == null) return;
    if (!e.getCurrentItem().hasItemMeta()) return;
   
    if ((e.getCurrentItem().getItemMeta().getDisplayName().contains("Fuerza"))) {
       
      e.setCancelled(true);
      if (pt > 0) {
          f2.set("Puntos_Disponibles", pt-1);
          f2.set("Fuerza", f+1);
          p.playSound(p.getLocation(), Sound.LEVEL_UP, 1, 1);
          p.closeInventory();
          try {
              f2.save(f1);
          } catch (IOException ex) { }
                }
            }
        }
  }

What do you mean "not works correctly"? Can you explain? Where are you adding/subtracting?

 

You're defining a new File and FileConfiguration every time someone clicks an inventory! You should be defining and creating these files in the main class passing values through a hierarchy. Also, you're assuming there are values and when it comes to programming assuming is bad.

 

@MajorSkillage
Thanks for your answer, but, can you give an example? I would appreciate

 

No. No one here will spoonfeed you code (or give "Example code" which is exactly the same).

Look at this to pass objects through a constructor:
http://docs.oracle.com/javase/tutorial/java/javaOO/classes.html

 

All of the values you have defined put them outside of your method in the same class for starters. Secondly I suggest when loading the configuration if these values are not defined then disable the plugin and say the configuration isn't configured correctly then save that old configuration as old_config.yml and make a new one called config.yml (would be better if you also showed the server-owner where they made their mistake or what they didn't define). I am not going to spoon-feed code as you should be learning from primary data in general when it comes to programming.
