Description

It would be nice to see an API for working with signed commands.

It also looks like Adventure in version 4.12 has the required API for this. FYI: SignedMessage.java

Motivation

In Minecraft, there are commands that allow you to write in private messages, as far as I understand, the command arguments are signed (FYI: Protocol#Chat_Command). For any use case that accepts player input and outputs, this would be a useful feature.

The first use case that comes to mind is message channels: global, local, etc.

Expected code

new CommandAPICommand(commandName)
     .withArguments(new AdventureSignedMessageArgument("message"))
     .executesPlayer((player, args) -> {
          final SignedMessage message = (SignedMessage) args[0];
          player.sendMessage(message, ChatType.CHAT.bind(Component.text("local")));
     }).register();
