N3rdy-lib

The library gives mod authors ready-made code objects to reuse in future projects. Its NbtObjects classes let a mod work with NBT compounds directly, since each object implements the NbtElement interface. Data handling is already written, but synchronising an NbtCompound between client and server is still left to the author.

A further interface lets items respond to a left-click held down on the mouse button, and a method reports that held state. Attribute modifiers can be granted to items anywhere in the general inventory, which suits charms, amulets and custom equipment slots that should update once rather than on every tick. The update runs every 5 ticks to keep the cost low. Client and server methods are both provided, and the shared method should be used unless a specific one is stated.

The mod is published for Fabric only, for the game versions 1.20.1, 1.20.2 and 1.20.3, with 1.0.1 for 1.20.3 as the latest file from 2024-11-05. A server running it needs every connecting player to have it too. It is released under the Mozilla Public License 2.0 and is open source. Source code and an issue tracker are public.
