Module	What it is
`stargate-common`	Shared models + JDBC storage (SQLite / MySQL) used only by the Paper plugin
`stargate-paper`	The actual gate plugin — install this on every backend server
`stargate-velocity`	Proxy companion for Velocity — install on the proxy only if using cross-server gates
`stargate-bungee`	Same, for BungeeCord/Waterfall

Build everything with ./gradlew build. Jars land in each module's build/libs/.

Building a gate

Build a ring out of any block in gate.frame-materials (default: obsidian, gold block, birch/oak planks — matches an obsidian+gold arch design). Leave the middle hollow.
Embed a few blocks of gate.chevron-unlit-material (default black stained glass) into the ring — these light up to gate.chevron-lit-material (default glowstone) as the gate dials.
Place a sign on the outside of the frame with:
- Line 1: [Stargate]
- Line 2: network name (blank = default network)
- Line 3: gate name (blank = auto-generated)
- Line 4: hidden to keep it out of the cycle list, otherwise blank

The plugin flood-fills the frame from the block behind the sign, confirms it's a fully enclosed ring, and registers the gate. If nothing happens, the ring isn't sealed or none of its blocks match frame-materials.

Using a gate

Right-click the sign: cycles the destination shown on line 3 among the other gates on the same network.
Left-click the sign: dials the shown destination — chevrons light in sequence, then the interior fills with gate.iris-material (default water). Walk into it to teleport. It auto-closes after dialing.open-seconds.

Multi-world

Gates are addressed by network name, not world — a gate on any loaded world can dial any other gate on the same network regardless of world, exactly like same-server cross-world travel in the original Stargate mod.

Cross-server (Velocity / Bungee)

Set storage.type: mysql in every backend server's config.yml and point them at the same database — this is how servers see each other's gates.
Give each backend a unique server-id in config.yml that matches its name in the proxy config (velocity.toml / config.yml servers list).
Set cross-server.enabled: true on every backend.
Drop stargate-velocity (or stargate-bungee) into the proxy's plugin folder.

When a player dials a gate hosted on another backend, the Paper plugin asks the proxy (over the stargate:teleport plugin channel) to connect the player to that server; once they land, the proxy forwards a delivery message so the destination server's Stargate instance teleports them to the gate's exit point.

Permissions

stargate.use (default: true) — dial/cycle gates
stargate.create (default: op) — build new gates
stargate.destroy (default: op) — break your own gates
stargate.admin (default: op) — reload, break/manage any gate

Commands

/sg list [network]
/sg destroy (look at a gate's sign)
/sg reload
