Arcadia Lib

by aminoquiz

Arcadia Lib is the shared foundation that other Arcadia mods are built on, providing a database layer, player data management and a debug mode.

What it does

Arcadia Lib adds no gameplay on its own. It supplies the common core that Arcadia Auction House, Arcadia Pets and Arcadia Prestige depend on, so installing it is only needed when another Arcadia mod asks for it. The mod runs on Forge and NeoForge, and it must be installed on both the server and every player's client.

The library offers a shared database option: a MySQL storage setting lets several servers, each identified by a server id, read from one database. When MySQL is set to enabled false, the mod runs without a database. Changes can be applied without a restart using the arcadia reload command. The same jar is used on every Arcadia mod, so one copy covers the whole set.

Game versions covered are 1.20.1 – 1.21.1, with files for 1.20.1, 1.20.2, 1.20.3, 1.20.4, 1.20.5, 1.20.6 and 1.21.1. The latest Forge build is 1.2.15 for 1.20.6, and the latest NeoForge build is 1.21.1-1.3.0 for 1.21.1. The code is released under All rights reserved, so the mod is not open source.

Key features

  1. Shared database

    A MySQL storage layer with a server id lets several servers use one database for player data.

  2. Staff tools

    Staff chat, timed mutes with alerts, and roles named Helper and Admin give moderators controls.

  3. Arcadia Hub

    Pressing L opens one menu that lists the Arcadia mods installed, with cards, dashboard tabs, tables, achievements, teleports and cooldowns.

  4. Ready-made APIs

    Other Arcadia mods can call prepared APIs from the library instead of writing their own storage and menu code.

  5. Currency fallback

    When Numismatics is installed, its currency is used; otherwise an emerald wallet item serves as the currency.

Use cases

Who it’s for: Server owners who run Arcadia mods and want shared player data, and modders who build on the Arcadia core.

Questions

Does Arcadia Lib need to be installed on its own?

No. It adds no gameplay by itself, so it is only needed when another Arcadia mod such as Arcadia Auction House, Arcadia Pets or Arcadia Prestige asks for it.

Does Arcadia Lib have to run on the server and the client?

Yes. Every player and the server need a copy of the mod.

Is a MySQL database required?

No. Setting MySQL to enabled false lets the mod run without it, while a database is needed for several servers to share player data.

Which game versions does Arcadia Lib support?

Files cover 1.20.1 – 1.21.1 for Forge and NeoForge, with 1.21.1-1.3.0 for 1.21.1 as the latest NeoForge build.
