Owo-lib 9minecraft Mod provides the background code needed to run many popular Minecraft additions. It acts as a required base layer for tools like the Accessories mod and the Aether. You only need to add this file to your game when another mod tells you it is missing.
Features:
- Hidden Engine: Adds zero new blocks, items, or monsters to your world on its own.
- Menu Builder: Helps other mods create custom menus and screens for you to click through.
- Settings Maker: Generates options menus automatically so you can change rules in your favorite mods.
- Makes sure the game client and server talk to each other properly without errors.
- Handles the math for particles, item groups, and data storage behind the scenes.
- Stays completely out of your way until a larger mod asks for it to load.
