java.lang.Thread.run(Thread.java:748) [?:1.8.0_152] Here's my command class: public class CommandAuthenticate extends CommandBase { public HashMap<String, Integer> hashMap = new HashMap<String,

registering this command in: @EventHandler public void serverStarting(FMLServerStartingEvent event) { event.registerServerCommand(commandAuthenticate); }
April 1, 20187 yr Your command class should not even compile, if it is what you've posted. 11 minutes ago, Alsan Ali said: @Override public boolean isUsernameIndex(String[] args, int index) { return false; } @Override public int compareTo(ICommand o) { return 0; } That said, this is just flat wrong. Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice. Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked. DO NOT PM ME WITH PROBLEMS. No help will be given.
