Blueprint poster

Okay, look–Blueprint isn't "fun" to play with because it doesn't do anything you can see. It’s just the technical glue for the Team Abnormals mods (like Autumnity or Neapolitan). But honestly, without it, those mods would probably crash your game or feel clunky. I think of it like the backend of a website–if it’s doing its job well, you won't even know it’s there. If you’re building a pack that’s supposed to feel like "Official Minecraft 2.0," you’re going to end up downloading this eventually.

JasonConfig (jsconfig) poster

Let’s be honest: if you're just playing the game, you don't even need to look at this–it’s a library mod. It basically swaps out Forge's standard config system for one powered by JSON, which is way more stable and doesn't freak out over things like empty lists. I’ve seen Forge configs break for the dumbest reasons, but this one handles complex stuff like Minecraft classes without a hitch. It’s a backend workhorse for versions like 1.20.1 and 1.21.1. If a mod you're using requires it, just toss it in your folder and forget it’s there.

LibrarianLib is a powerful library that handles a large number of standard codes. The main focus of LibrarianLib is an automatic serialization system with model creation, and also registration. This mod personalizes the GUI, extracts magic numbers and complex module control structures. The library has the utmost all-powerful and also adaptable particle system.
