ARRP

by Devan-Kerman

Runtime Asset and Data Generation API lets Fabric mods create resource packs in code while the game runs, instead of writing JSON files by hand.

FabricClient or server, optionalMozilla Public License 2.0Open source1.19 – 26.1.2

What it does

Developers use the library to generate recipes, loot tables, models and blockstates directly from Java code. Conditional resources can be produced as well, and the generated content works alongside ordinary resource packs. ARRP is published for Fabric only, with 10 release versions covering 1.19 – 26.1.2 and open source under the Mozilla Public License 2.0. Other mods require it, including Even Better Archeology, SpartanWeapons, Sakura Lib, C3 Blocks and Elysium Tweaks. Only the Fabric API needs to be present for it to work, and the library can run on a client or a server.

Key features

  1. Code-generated recipes

    Recipes can be defined in Java instead of separate JSON files, which keeps related content in one place.

  2. Runtime models and blockstates

    Models and blockstates are produced when the game starts, so asset data can follow the logic of the code that creates it.

  3. Conditional resources

    Resources can be generated only when a stated condition holds, letting one mod adapt its assets to other content.

Questions

Does Runtime Asset and Data Generation API need the Fabric API?

The library is published for Fabric only, so a Fabric loader is required. Other mods that depend on it can be installed alongside it on either a client or a server.

What the author says

An api for fabric that allows for the generation of resourcepacks at runtime via code. This allows you to add recipes/loottables/models/blockstates without json and in code, as well as allowing conditional resources. All while being compatible with normal resource packs.
