Mod PolyLib

PolyLib, the CreeperHost library mod

PolyLib is a lightweight library mod created by CreeperHost for its own Minecraft mods. Rather than adding a standalone dimension, mobs, or items, it provides reusable helper classes that simplify development, including tools for building flexible graphical interfaces and other common systems.

Designed to support Forge, Fabric, and NeoForge, PolyLib helps developers maintain compatible projects and port them between Minecraft versions more efficiently. It is mainly a technical dependency, often required by mods such as Soul Shards, BlockShot, MineTogether, Shrink, Steve’s Carts 2, and Chickens. For our Minecraft server community at BoxToPlay, it quietly provides the foundation needed for a stable modded experience.
