Formatting the chat

chat format example

The chat uses the PlayerChatEvent, it contains the formatter, the PlayerRef for the sender, the content as well as a list of targets (it's safe to assume the targets is the list of players who can see the chat message) You can cancel this event as well as modify the content and the formatter.

public class ChatFormatter {

  public static void onPlayerChat(PlayerChatEvent event) {
    PlayerRef sender = event.getSender();
    if(event.getContent().equalsIgnoreCase("poo")) {
      event.setCancelled(true);
      sender.sendMessage(Message.raw("Hey, you cannot say that!").color(Color.RED));
    }

    if(event.getContent().equalsIgnoreCase("you stink")) {
      event.setContent("i stink");
    }

    event.setFormatter((playerRed, message) ->
        Message.join(
            Message.raw("[COOL] ").color(Color.RED),
            Message.raw(sender.getUsername()).color(Color.YELLOW),
            Message.raw(" : " + message).color(Color.PINK)
        ));

  }
}

The formatter is the following interface:

  public interface Formatter {
    @Nonnull
    Message format(@Nonnull PlayerRef playerRef, @Nonnull String message);
  }
}
