🪶Installation

Modern OneBlock requires Java 25 and a Minecraft 26.1+ server. Paper and Folia are both supported.

• Drop ModernOneBlock-26.1.0.jar into the server plugins folder, then start the server once to generate the configuration and the island world.

• VoidGen is no longer required. The islands world is generated by a bundled void generator, so you can uninstall VoidGen.

• 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.

• Data lives in plugins/ModernOneBlock/. If you are updating from 1.0.8, read upgrading.md — your old plugins/OneBlock/ folder is moved for you.

Optional dependencies

Install any of these to enable the matching feature:

• Vault — moving money between a player's own balance and the island bank. The bank, shop and upgrades work without it.

• 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.
