        }else {
            player.sendMessage("Ca marche refais");
            getConfig().set("chevalier." + player.getName(), ".active");
        }
    }

Please help, thanks and sorry for my bad english

 

first off please use the Java syntax why you imput code that way it looks like this:

Code:java

@EventHandler
    public void onInterractGui(InventoryClickEvent event) {
        Player player = (Player) event.getWhoClicked();
        if (!main.choix.contains(player.getName()))
            return;
        switch (event.getCurrentItem().getType()) {
        case IRON_SWORD:
            chevalier(player);
            player.sendMessage("Ca marche a peu pres");
            break;
        case BLAZE_ROD:
            magef(player);
            break;
        case BOW:
            archer(player);
            break;
        case NETHER_STAR:
            ninja(player);
            break;
        case ICE:
            mageg(player);
            break;
        default:
            break;
        }
    }
 
 
 
    public void chevalier(Player player) {
 
        if (getConfig().getString("chevalier." + player.getName()).equals(
                ".active")) {
 
            player.sendMessage(ChatColor.GOLD + "Votre nouvelle classe est "
                    + ChatColor.DARK_BLUE + "Chevalier");
            main.enlever(player);
            main.chevalier.add(player.getName());
 
            player.closeInventory();
            main.choix.remove(player.getName());
 
        }else {
            player.sendMessage("Ca marche refais");
            getConfig().set("chevalier." + player.getName(), ".active");
        }
    }

Whats on lines 50 & 22 of your playerListener?

 

Line 22 : chevalier(player);
and line 50 : if (getConfig().getString("chevalier." + player.getName()).equals(".active")) {

 

if this isn't your main plugin file(the one that extends JavaPlugin) then you need to add:

Code:java

Plugin plugin = Bukkit.getServer().getPlugin("plugin name");

and then instead of

Code:java

getConfig().

do

Code:java

plugin.getConfig().
