About FlowGate
FlowGate is a world-access firewall plugin for Minecraft servers.
It protects restricted worlds by controlling cross-world teleports and denying unauthorized entry attempts.
All denied attempts are logged and available in GUI.
​
Why this plugin exists
  • Many servers open worlds gradually (Nether/End later in progression)
  • Players can still try to bypass with commands, portals or plugin teleports
  • FlowGate blocks those entries with clear rules and messages
  • Staff can manage everything quickly through GUI

Core Features
  • Per-world rule system: Open / Closed / Permission-Restricted
  • Cross-world teleport guard by teleport cause
  • Join and respawn enforcement
  • Safe fallback teleport to configured world spawn
  • GUI management (rules + recent denied logs)
  • Local JSON storage (no MySQL/SQLite required)
  • Fast diagnostics command: '/flowgate why <player>'

How rules work
  • If 'enabled: false' -> world is open
  • If 'enabled: true' and permission is empty -> world is closed (except bypass permission)
  • If 'enabled: true' and permission is set -> only players with this permission can enter

Default guarded teleport causes
Code (Text):

NETHER_PORTAL
END_PORTAL
END_GATEWAY
