Languages and menus · RoodyPortals · Documentation

language in config.yml: the file of lang/ the server speaks (en, es, or your own: copy one as lang/<code>.yml).
per-player-language: true: each player gets messages and menus in their Minecraft language when lang/ has it. Holograms and the console use the server language.
The lang file has every message, the menus' titles, names and lores, the default hologram lines and the names of destinations, sounds and particles.
menus/<menu>.yml: where each button goes and with which item (slot, material, glow, custom-model-data, item-model, sound), rows, filler, click sound, and your own items (decoration, or buttons that run [player]/[console] commands, send a [message], play a [sound] or [close]). New buttons of a new version are added by themselves.
