    I have this language.yml that was working fine. Until I restarted the server. I changed it, in any way possible but still have no solution. Any help?

    Code (Text):
    public static FileConfiguration getLanguageConfig() {

            File folder = new File(Core.getInstance().getDataFolder(), "language.yml");
            FileConfiguration fileConfiguration = YamlConfiguration.loadConfiguration(folder);

            return fileConfiguration;

        }
    The config is there, but it doesn't find it and gives me errors.

    I saw you capitalized the first letter in the thread title, is the config name 'Language.yml' or 'language.yml'?

    language.yml.

    It was working fine, and then suddenly stopped.

    Just try this for me:

    Code (Text):

    public static FileConfiguration getLanguageConfig() {

            File folder = new File("/plugins/YOUR PLUGIN FOLDER/language.yml");
            FileConfiguration fileConfiguration = YamlConfiguration.loadConfiguration(folder);

            return fileConfiguration;

        }
     
    If that works then there is a problem with getting the data folder. If it doesn't work, then there is another problem.

    MrHodge

    This null pointer is in Inventories.java on line 97. Post the method createChestGUI() from the Inventories class.

    Was about to, but I must have edited out by accident, here it is.

    Inventory inventory = Bukkit.createInventory(p, 9, Configs.getLanguageConfig().getString("current-mounts-chest-name").replace("&", "§"));

    I really think it's the config.
     
    #8 Bladian, May 13, 2015
  17. MrHodge

    MrHodge

    Is this string in the path "current-mounts-chest-name" null? Debug using
    PHP:
    System.out.println(Configs.getLanguageConfig().getString("current-mounts-chest-name"));
     
    #9 MrHodge, May 13, 2015

    Bladian

    It's definitely in the config, i'll double check now.

    Okay so it's definitely returning null. Here is how I have it set up.

    First of all the error.

    Then here is how I retrieve it.

    Code (Text):
    public static FileConfiguration getLanguageConfig() {

            File folder = new File("plugin/Mounts/language.yml");
            FileConfiguration fileConfiguration = YamlConfiguration.loadConfiguration(folder);

    For some weird reason it doesn't recognize the "&" even though I replace it all to "§"

    Config:

    Code (Text):
    gui-chest-name: "&e&lMOUNTS"
    current-mounts-chest-name: "&e&lMOUNTS"
    rental-mounts-chest-name: "&e&lRENTAL MOUNTS"
    advertisement-chest-name: "&e&lADVERTISEMENTS & SALES

    gui:
      mounts-item: "&e&lMounts"
      rent-mount-item: "&e&lRent-A-Mount"
      advertisement: "&4&lAdvertisements and Sales"
      exit: "&4&lExit"
    So it obviously finds it, but doesn't change the alternate code.

    Here is where I tested it:

    Code (Text):
    p.sendMessage(Configs.getLanguageConfig().getString("current-mounts-chest-name").replace("&", "§") + "Not there or there");

    Did a bit of research and the & character isn't the problem. There is probably multiple spaces somewhere in your file which is messing with the parser. Also, use ChatColor.translateAlternateColorCodes('&', String) instead of String#replace().

    I double checked every single line and there is no extra space. Here just incase:

    current-mounts-chest-name: "&e&lMOUNTS"
    rental-mounts-chest-name: "&e&lRENTAL MOUNTS"
    advertisement-chest-name: "&e&lADVERTISEMENTS & SALES

    gui:
      mounts-item: "&e&lMounts"
      rent-mount-item: "&e&lRent-A-Mount"
      advertisement: "&4&lAdvertisements and Sales"
      exit: "&4&lExit"
