LibrarianLib 1.17.1, 1.12.2 is the library mod to end all library mods. It doesn’t attempt to do much else than take the pain out of modding. It can handle a great deal of boilerplate code that you really shouldn’t have to touch. Its largest components are an automatic serialization system, automatic model creation and registration, a powerful GUI library that takes out the magic numbers and complex control stuctures by making everything modular, and a powerful and flexable particle system.

LibrarianLib

Here’s a quick overview of the major things we help with:

  • Generating models that aren’t there (can be turned off)
  • Automatic registration of item colors, models, statemappers, and all other things related to models
  • Automatically syncs tileentity fields and packet fields marked with @Save (some setup may be required)
  • A GUI library that allows very easy construction and design of GUIs

Features:

  • Includes a flexible system for building in-game user interfaces (GUIs).
  • Adds a high-performance particle system that can handle thousands of particles at once.
  • Provides a shader system for adding custom visual effects.
  • Features an automatic system that helps with saving and loading data.
  • Comes with a simple tool for managing network communication.
  • Lets you create data-driven sprite sheets to keep your GUI code clean.
