Solved Null GUI

Hi there, so im trying to open a GUI when i do "p.openinventory(blabla(player))", the problem is that i have a null in that line. I have the GUI in another class and i have a constructor in all. Maybe i need to register the GUI in the main Class?

I tried "p.openinventory(blabla()) and "inv.blabla(player);"

 

Main

Code:

public class testGUI extends JavaPlugin{
 
    Plugin instance;
 
    public GUI inv;
     
    public File testFile = new File(this.getDataFolder() + "/alola.yml");
    public FileConfiguration testConfiguration = YamlConfiguration.loadConfiguration(testFile);
    @Override
    public void onEnable() {
        if(!(getDataFolder().exists())){
            getDataFolder().mkdir();
        }
        try {
            testConfiguration.save(testFile);
            testConfiguration.load(testFile);
        } catch (IOException | InvalidConfigurationException e) {
            e.printStackTrace();
        }
        instance = this;
        getLogger().info("yoyo");
        registrarComandos();
        registrarEventos();
    }
 
    @Override
    public void onDisable() {
        getLogger().info("yaya");
    }
    public void registrarComandos() {
        getCommand("test").setExecutor(new Comandos(this,inv));
    }
    public void registrarEventos() {
        PluginManager pm = Bukkit.getPluginManager();
        pm.registerEvents(new Eventos(this), this);
    }
}

GUI

Code:

public class GUI {
 
    testGUI main;
 
    public GUI(testGUI mainClass) {
        main = mainClass;
    }
 
    public Inventory abrirMenu(Player p) {
        ItemStack item0 = new ItemStack(Material.DIAMOND);
        ItemMeta meta0 = item0.getItemMeta();
        meta0.setDisplayName(ChatColor.AQUA + "Test");
        meta0.setLore(Arrays.asList("Another TEST"));
        item0.setItemMeta(meta0);
     
        Inventory inventario = Bukkit.createInventory(null, 9, ChatColor.AQUA + "yoyo");
        inventario.setItem(1, item0);
     
        return inventario;
     
    }
}

command

Code:

    testGUI main;
    GUI inv;
    public Comandos(testGUI mainClass,GUI invClass) {
        main = mainClass;
        inv = invClass;
    }

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if(sender instanceof Player) {
            Player player = (Player) sender;
            if(cmd.getName().equalsIgnoreCase("test")){
                if(args.length == 1) {
                    String nombre = args[0];
                    if(nombre != player.getCustomName()) {
                        inv.abrirMenu(player);
                        player.sendMessage(ChatColor.GREEN + "Has abierto el para " + nombre);
                        return true;
                    }else {
                        player.sendMessage("no puedes castigarte a ti mismo aunk seas mazoquista");
                    }
                }
            }
        }
        return false;
    }

I have the null on "inv.abrirMenu(player);"

 

@Ahrigumi My guess is that it's because you are not initializing the variable 'inv' in the main class.

 

Yes! I was thinking about that but i dont reaaaally remember how to do that haha. In my last plugin i just create the GUI in the mainClass, but in this case is in another jeje

 

ups, removed
