How can I use this on my java game?

[yeppiidev]

I am making a 3D game using Java and I would like to use this on my game. But how can I do this?

[portlek]

create a dispatcher with a custom command sender class.
use register method in the dispatcher class to register commands.
use execute method in the dispatcher class to execute registered commands.

Any example code?

[portlek]

public interface CommandSender {

  void sendMessage(String message);
}

public final class App {

  private final CommandDispatcher<CommandSender> dispatcher = new CommandDispatcher<>();

  public static void main(final String[] args) {
    new App().exec();
  }

  public void exec() {
    this.dispatcher.register(LiteralArgumentBuilder.literal("testCommand")
      .executes(context -> {
        context.getSource().sendMessage("xxx");
        return 0;
      }));
      final var client = new Client(this.dispatcher);
      client.start();
  }
}

public final class Client implements CommandSender {

  private final CommandDispatcher<CommandSender> dispatcher;

  public Client(final CommandDispatcher<CommandSender> dispatcher) {
    this.dispatcher = dispatcher;
  }

  @Overrider
  public void sendMessage(final String message) {
    System.out.println(message);
  }

  public void start() {
    // Start client, initiate other things etc.
  }

  public int runCommand(final String command) {
    return this.dispatcher.execute(command, this);
  }
}

@portlek ok cool. I'll try it. If there is no problem with that code, I will close this issue.

[portlek]

actually, it works or not, you should understand the concept.

[yeppiidev]

@portlek okay

I did what you said and now I get this CommandSyntaxException
(For some context, I'm using this on the multiplayer server of my main game)

[portlek]

probably you didn't register command or typing the wrong command, I can't say anything without any single code tho .-.

Try and catch, see what in the stacktrace is causing it.
