commands

Анықтаманың өзі ағылшын тілінде: ол WIT файлдарынан автоматты түрде жасалады.

Chat and console commands registered by mods. A registered command is routed to its mod for every allowed sender, before the built-in commands. Vanilla only treats / lines from moderators and admins as commands; mod commands work for any player unless min-role says otherwise.
