5555ff-lib

What is this?

5555ff lib is the shared library that powers all of my datapacks/mods. It handles cross-pack compatibility, provides a management interface and includes shared utilities.

Some of my packs require this library (especially those that modify vanilla loot tables), for others it’s just optional.
The packs then work standalone, but gain some extras when the library is installed.

Why does it exist?

When multiple datapacks modify the same vanilla loot table (e.g. Mob Heads adding a head and e.g. Name Tag adding the name tag drop) only one can win, the other one gets overwritten. 5555ff helps me manage that, preventing clutter in datapacks and making it easier for me to create new datapacks.

Beyond compatibility, the library also serves as a central hub for managing all datapacks.

In the future I will most likely include more features and more shared code.

Features

Loot Table Compatibility

Multiple of my datapacks can modify the same vanilla loot table without overwriting each other.

Automatic uninstalls

You don’t need to uninstall datapacks manually

Shared Utilities _(expanding over time)_

Common functionality like predicates (e.g. sneak detection) and reusable code that multiple packs rely on –> maintained in one place instead of duplicated across packs.

Supported Packs

This library supports most of my datapacks. Any pack that lists 5555ff lib as a dependency will work.

For Developers

5555ff lib acts as a central dispatch layer for vanilla loot tables. Instead of each datapack overriding vanilla tables directly (which causes conflicts when multiple packs modify the same mob), the library handles all vanilla overrides. This way, multiple packs can modify the same mob’s drops without overwriting each other.

If you’re interested in making your pack compatible, feel free to reach out on Discord or open an issue on codeberg.

Why the name? 5555ff is the color used as the background color in all of my icons
