If someone types /commands they will get a bunch of commands like /nuke, /feed, /craft etc and the commands are a green pane and when they get purchased it takes your money and they become a red pane and you have unlocked the command and a fully customisable commands menu Im not really good with java stuff and i dunno if i have to have certain essential things for this to work
ive watched the video on the page and im confused on how to set it to give you a command when u purchase it in the gui
