Mod ARRP

ARRP, Runtime Asset and Data Generation API

ARRP is a Fabric library for Minecraft Java Edition that lets mods generate resource pack content at runtime through code. Rather than relying exclusively on prepared JSON files, developers can create recipes, loot tables, item models, block states, and other assets dynamically.

Its conditional resource support makes it useful for mods with configurable or mod dependent content, while generated resources remain compatible with regular resource packs. ARRP can support both clients and servers, helping deliver a more flexible Minecraft server experience. At BoxToPlay, we recommend it mainly as a technical dependency for mods that need dynamic content generation.
