The game shows my command by auto complete, so I think the game knows my command.

However, system always shows "Unknown command".

 

public class SetDistanceCommand {
  public static void register(CommandDispatcher<CommandSource> dispatcher) {
    dispatcher.register(Commands.literal("setdistance")
            .requires(source -> source.hasPermissionLevel(2))
            .then(Commands.argument("blocks", IntegerArgumentType.integer()))
            .executes(context -> {
              context.getSource().sendFeedback(new TranslationTextComponent("commands.mymod.setdistance"), true);
              MyModConfig.distanceToNormal = IntegerArgumentType.getInteger(context, "blocks");
              return 0;
            }));
  }
}

How do you register your command?

This is it.

@SubscribeEvent
  public static void onServerStart(FMLServerStartingEvent event) {
    SetDistanceCommand.register(event.getCommandDispatcher());
  }

After looking at the vanilla code, I noticed the .executes() must follow the Commands.argument() immediately. Thus not when .then() already has been executed.

Howdy

The syntax of commands is tricky to get right.

This working example might help explain it

It works!

Thank you!!
