Double Doors

A Bukkit/Spigot plugin that opens mirrored double doors together, with low-latency syncing and optional compatibility handling for common server stacks.

Features

• Same-tick partner door sync (no scheduled 1-tick delay)
• Strict mirrored pair matching for doors:
  • same door type
  • same facing direction
  • opposite hinge
  • side-by-side only
• Optional recursive opening support for non-door openables (fence gates/trapdoors)
• Per-player toggle: /doubledoors toggle
• LuckPerms-friendly permission nodes
• GriefPrevention compatibility check for linked-door claim access
• Duplicate interaction debounce (helps packet duplication patterns seen with some Bedrock/Geyser flows)
• Translation support via JSON language files (built-in + custom)

Compatibility

Geyser / Floodgate

• Plugin declares soft-depends on Geyser-Spigot and floodgate.
• A short duplicate-interaction debounce window is used to avoid rapid duplicate toggles on the same block.

LuckPerms

• Works through standard Bukkit permissions, so LuckPerms applies automatically.
• Use doubledoors.use to allow/deny linked opening behavior.

GriefPrevention

• Plugin declares a soft-depend on GriefPrevention.
• When present, linked-door interaction is checked against claim build permission before toggling the partner door.

Commands

• /doubledoors reload - reload config
• /doubledoors toggle - toggle behavior for yourself
• /doubledoors server-toggle - toggle behavior server-wide
