# 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)

## 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
