Hello, I came across a problem that I can't deal with, the plugin to hide the player's nickname, the plugin works fine, but there is a problem because I have a plugin for the tablist and generates errors by hiding the nickname.

@pvtr_ 1. You could use some loops to shorten the amount of lines. 2. 'u' is null, which means that "UserManager.getUser(player)" is returning null, try showing us that method.
Code: public static void registerUser(UUID uuid, String name, String ip) { User user = new User(uuid, name, ip); RankingManager.addRanking(user.getRanking()); RankingManager.getMineRankings().add(user); users.put(uuid, user); } public static User getUser(String nick) { for (User user : users.values()) { if (user.getName().equalsIgnoreCase(nick)) return user; } return null; }
@pvtr_ That should be throwing errors because the argument is of type Player but the parameter is of type String. Did you change your code while waiting for a response?
