In general, I already know and I managed to create a command that creates a Fireball using "/mkt fireball <strenght>", but I think I'm doing it the wrong way: My command is "/mkt", and I'm creating others using the first argument, like "fireball". Onwards I can create a "/mkt build <shape>", with "build" being the argument. I'm pretty sure this is wrong, and that there is a way to create a command from a better command, such as "/rftdim safedel <dimId>" from RFTools Dimensions. In short, I want to implement something similar to "/rftdim" in my mod, which after that I can call my command. This shortcut is easier for the player to find out where the commands come from. In Main.java, i am using this to register: @EventHandler public static void serverStarting(FMLServerStartingEvent event) { ModCommands.registerCommands(event); } Herei i register: public class ModCommands{ public static void registerCommands(FMLServerStartingEvent event) { event.registerServerCommand(new BaseCommand()); } } And here i use the first argument to call a command, like Fireball or Build: public class BaseCommand extends CommandBase { @Override public String getCommandName() { return "mkt"; } @Override public String getCommandUsage(ICommandSender sender) { return "/mkt <command>"; } @Override public void execute(MinecraftServer server, ICommandSender sender, String[] args) throws CommandException { List<String> commands = new ArrayList<String>(); commands.add("help"); commands.add("fireball"); if (args.length > 0) { if(args[0].equals("fireball")){ new Fireball().execute(server, sender, args); } } else{ String formatted = ""; formatted += TextFormatting.BLUE; formatted += "/mkt help"; String notFormated = ""; notFormated += TextFormatting.WHITE; notFormated += "to help."; sender.addChatMessage(new TextComponentString(formatted + " " + notFormated)); } if(args.length > 0) { if (!commands.contains(args[0])) { String formatted = ""; formatted += TextFormatting.BLUE; formatted += "'" + args[0] + "'"; String notFormated = ""; notFormated += TextFormatting.WHITE; notFormated += "are not a Mekatronic command."; sender.addChatMessage(new TextComponentString(formatted + " " + notFormated)); } } } } All my others command extends CommandBase, my BaseCommand just decides which command to call. I tried to find out in RFToolsDim's .jar how they implemented the commands, but I'm new to java, and I don't understand anything.
