About this Mod
What is this
Simple library mod with helpful data attaching and networking utilities including attaching data to entities, chunks, players, and worlds with low boilerplate code. Its own system built from the ground up for multiloader support. Offers an incredible packet utility for multiloader network packet handling for all directions.
For players
Your favorite mods may use this to attach data to things or to send things across the network.
For devs
This library offers two primarily utilities: attaching data to chunks, levels, players, entities, and block entities. This project is aimed at multiloader projects that support forge, fabric, and neoforge. This mod does NOT save to the internal data systems said loaders have such as Forge Capabilities at the moment, this may be subject to change in the future though! This mod also offers multiloader network/packet registration and handling. For examples on how to do custom networking or attaching data, please see the wiki.
