Solved %player% in config

Hello there! , So.. is very simple, i just want to know, how can i define the variable %player% to put that inside the config.

 

@timtower so i use it, but i have an NPE and im not really sure about the problem

Code:

                     if (args[0].equalsIgnoreCase("start")) {
                        String clase = args[1];
                        String mensaje = main.mensajesConfig.getString("teleported-class");
                        String newMessage = mensaje.replaceAll("%class%", clase);
                        if (main.oldLoc.containsKey(player.getUniqueId())) {
                            for (Player enClase : Bukkit.getOnlinePlayers()) {
                                if (main.oldLoc.containsKey(enClase.getUniqueId())) {
                                    enClase.sendRawMessage(newMessage);
                                    Bukkit.getScheduler().scheduleSyncDelayedTask(main, new BukkitRunnable() {
                                        @Override
                                        public void run() {
                                            main.entrarClase(enClase, clase);
                                            enClase.sendTitle(ChatColor.GREEN + clase, ChatColor.GOLD + "Professor: "
                                                    + ChatColor.DARK_RED + player.getDisplayName());
                                            return;
                                        }
                                    }, 80L);
                                    return true;
                                }
                            }
                        }

                    }

The npe appear on String newMessage = mensaje.replaceAll("%class%", clase);

and the config is

Code:

teleported-class: "You will be telerported to the %class%"

 

@timtower i will show you the error

and yes, corrected the typo :$

 

@Ahrigumi I don't know if it makes any difference but maybe try '.replace()' instead of '.replaceAll()'.

 

@KarimAKL I tried with it, but i have the same npe

 

@timtower im sorry, but how works "Pattern.Quote("%player%")" ??

 

@timtower , ok im sorry again, the problem was "replaceAll()" , i used it, but the correct was just replace() . Im so stupid hahahah , thanks to all , is fixed
