🪶Installation

UltimateOneBlock requires Java 21, a 1.21+ server (Paper recommended), and the VoidGen plugin, which is a hard dependency used to generate the empty island world.

• Install VoidGen and UltimateOneBlock into the server plugins folder, then start the server once to generate the configuration and the island world.

• By default the plugin uses an embedded H2 database and works with no extra setup.

• To use MariaDB, set database.type to MariaDB and fill in the database.mariadb credentials in config.yml.

Optional dependencies

Install any of these to enable the matching feature:

• Vault — economy backend for the island reset cost.

• PlaceholderAPI — %oneblock_*% placeholders.

• LuckPerms — per-group island member limits (custom-max-players).

• HolographicDisplays, DecentHolograms, FancyHolograms or CMI — leaderboard/info holograms.

• MythicMobs, ItemsAdder, Nexo, JetsMinions — content integrations.
