Commands

Plugins register custom chat commands that the player can run with /commandname. The proxy routes these to your plugin’s execute function.

​
Registering a command

ctx.commands.register({
  name: 'myplugin',
  description: 'Does something useful',
  usage: '/myplugin [on|off]',
  aliases: ['mp'],
  execute: (args, sender) => {
    const sub = args[0]?.toLowerCase();
    if (sub === 'on') {
      ctx.storage.set('enabled', true);
      ctx.client.sendChat('§aEnabled');
    } else if (sub === 'off') {
      ctx.storage.set('enabled', false);
      ctx.client.sendChat('§cDisabled');
    } else {
      ctx.client.sendChat(`§7Usage: /myplugin on|off`);
    }
  },
});
  • name - The main command name (e.g. myplugin → /myplugin). Use lowercase.
  • description - Shown in help (e.g. /dhelp).
  • usage - Optional; shown in help.
  • aliases - Optional; e.g. ['mp'] allows /mp as well.
  • execute - (args: string[], sender: { username: string; uuid: string }) => void | Promise<void>. args is everything after the command (e.g. /myplugin on → args = ['on']).

​
Unregistering

If you need to remove a command at runtime: 
ctx.commands.unregister('myplugin');
Aliases are unregistered automatically when the plugin unloads. You don’t need to unregister for normal shutdown - the proxy cleans up all plugin commands when a plugin is unloaded.

​
Example (from auto-glhf)

The auto-glhf example registers /glhf with subcommands: 
ctx.commands.register({
  name: 'glhf',
  description: 'Configure auto-glhf',
  usage: '/glhf [on|off|set <message>|delay <ms>]',
  execute: (args) => {
    const sub = args[0]?.toLowerCase();
    if (sub === 'on') {
      ctx.storage.set('enabled', true);
      ctx.client.sendChat('§7[GLHF] §aEnabled');
    } else if (sub === 'set') {
      const msg = args.slice(1).join(' ');
      if (msg) ctx.storage.set('message', msg);
    }
    // ...
  },
});
Commands run in the same context as the rest of your plugin; you can use ctx.client, ctx.storage, ctx.gameState, etc., inside execute.
