How can I make a plugin that each time you write an unknown command it tells you This command is unknown, I know there is already a thing in minecraft about it, but I want to make a custom one where it says the Server Name then unknown command blah blah ect ect..
@PoisonStar You can do this with ProtocolLib https://bukkit.org/threads/help-me-change-unknown-command-message.152073/ Take a look at the third post.
