BusyHub

A hub/lobby plugin for Paper (and Folia) servers: server-select compass, launch pads, portals, double jump, chat/command lockdown, world protection, and a personal player-visibility toggle.

Full documentation: docs/

Requirements

• Paper 1.21.10 or newer (built against the Paper API, compiles and runs unmodified on later Paper/Folia builds through 26.2)
• Java 21+
• Folia-supported

Features

• Server-select compass — right-click item that opens a config-driven GUI; menu items fire [BUNGEE], [MESSAGE], [SOUND], [MENU], [PLAYER], [CONSOLE], or [VELOCITY] actions.
• Launch pads — register any pressure plate as a pad; stepping on it launches the player in whichever direction they're facing, with configurable velocity/height and its own action list.
• Portals — wand-based cuboid selection, trigger-on-enter actions, optional water/nether block fill.
• Double jump — double-tap-space velocity boost in place of actual flight, with a cooldown.
• World protection — block place/break, item drop/pickup, weather, mob spawning, fire spread, leaf decay, death messages, and general interaction can all be blocked hub-wide, with a bypass permission and a per-world opt-out list.
• Anti-void — a player who takes void damage is returned to spawn instead of falling forever.
• Chat & command lockdown — a global chat on/off switch, plus a always-on blocklist for commands that leak server info (/plugins, /version, ...).
• Player visibility toggle — a personal item any player can use to hide/show other players from their own view (not vanish — it never changes whether others can see you).
• Anti-exploit hardening — the compass GUI locks player movement while open, launch pad/double-jump boosts are checked for wall-tunneling, and the compass item can't be duplicated or dropped.
