Advanced Core Info (ACI)

by lalis.jan

Advanced Core Info, or ACI, is a shared library that other mods build on for config loading, localization, tooltips and client data transfer, and it is required by two catalog mods.

FabricForgeNeoForgeClient and serverMIT LicenseOpen source1.20.1 – 26.3

What it does

ACI serves as a common base for companion mods, so they can share one set of code rather than duplicating it. Its plugin API is loader independent, and plugins are discovered and registered at startup on Fabric, Forge and NeoForge alike.

Shared building blocks cover tooltips arranged as a tree, a layout engine for model builders, and recipe viewer agnostic widgets such as scrollable panes with tree and branch rendering. The mod also handles shared configuration, including loading common settings, and localization, including translation keys that several mods use. Client data transfer and data collection with compression are part of the same core.

ACI is published for Fabric, Forge and NeoForge from game version 1.20.1 up to 26.3. The mod runs on client and server, so both sides need it, and it is released under the MIT License as open source. Source code, an issue tracker and a wiki are linked from the project.

Key features

  1. Shared core library

    Common code for companion mods lives in one place, so each mod that depends on it relies on the same base.

  2. Tooltip tree system

    Tooltips can be built as a tree, with nested entries that other mods fill in through the core API.

  3. Model builder layout engine

    A layout engine positions elements for model builders, giving other mods a common way to arrange their interface parts.

  4. Shared configuration and localization

    Config loading for common settings and translation key handling are provided once, for every mod that uses the library.

Questions

Does Advanced Loot Info need Advanced Core Info?

Yes. Advanced Loot Info lists ACI as a required dependency, and Advanced Worldgen Info does the same, so ACI must be installed with either of them.

Does Advanced Core Info have to be installed on both sides?

Yes. A server running it needs every connecting player to have it too.

Which loader files exist for Advanced Core Info?

Files exist for Fabric, Forge and NeoForge. The latest Fabric and NeoForge builds are 26.3-1.4.1 for 26.3, and the latest Forge build is 1.21.1-1.4.0 for 1.21.1.
