                                {
                                   
                                    Arena a = null;
                                    a = new Arena(aname);
                                    a.setHub(p, aname);
                                    p.sendMessage(Main.nserv + "Hub setado com sucesso!");
                                    return true;
                                   
                                } else {
                                    p.sendMessage(Main.nserv + ChatColor.RED + "Essa arena não existe!");
                                    return true;
                                }
                            }
         }

 

I think the plugin is null, can you post the onEnable part?

 

@Gartenzaun

Code:

@Override
    public void onEnable()
    {
       
    }
    

But the arena class isn´t listener.

 

Try this (I think that you programm in your main class):

Code:

    public static nameOfYourClass plugin;
    @Override
    public void onEnable() {
        plugin = this;
    }

And call your commands with nameOfYourMainClass.plugin.getConfig()...

 

@Gartenzaun I have it in my Arena Class:

Code:

static Main plugin;
    public Arena(Main instance) {
        Arena.plugin = instance;
    }
    

 

Try calling your commands with Arena.plugin.getConfig() instead of plugin.getConfig()

 

@Gartenzaun Doesn´t work.
