Understanding What CrumbsLib Does in Your Game

Background Operation

CrumbsLib is a foundational library mod that operates entirely in the background. It does not introduce standalone gameplay mechanics, direct crafting recipes, or standalone tools on its own. Instead, it provides the underlying structure that other mods require to register custom blocks, items, entities, tags, and status effects cleanly in the game files. When you install mods that depend on CrumbsLib, this library automatically handles event registration by sending game actions to the proper event bus behind the scenes.

Impact on Vanilla Survival

If you install CrumbsLib into your game without any other mods that require it, you will notice no changes to standard vanilla survival gameplay. World generation, vanilla mob behavior, health, hunger, and standard progression remain completely unaltered. CrumbsLib is designed to maintain consistent game logic across different setups using shared types, ensuring that dependent content runs predictably. You should keep CrumbsLib installed in your active mods folder as long as you have any content mod that lists it as a prerequisite.
