Overview#
Data Attributes is a library mod for Minecraft (Fabric) that overhauls the entity attribute system to be more dynamic and customizable. Originally developed as a core component of the PlayerEx mod, it was later spun off into a standalone project to provide a robust framework for RPG-style attribute systems, follow-on attributes, and server-side configuration.
By default, the mod adds no new in-game content like items or mobs. Instead, it detaches attributes from the game instance and makes them world-specific. This allows pack makers and mod developers to modify every aspect of the attribute system—including vanilla attributes—using simple JSON files in a datapack. This system is essential for creating complex progression systems where increasing one stat (like Strength) automatically buffs others (like Attack Damage).
