About this project
What does PJ CoreLib add?
CoreLib 🏁
PJ CoreLib is the shared foundation of the PJ Hytale mod ecosystem. It is not a standalone gameplay mod, but the common layer that improves compatibility, visual consistency and the overall experience when using multiple PJ mods together.

Key features
- Mod and pack detection: CoreLib identifies PJ mods and also asset/data pack content to reflect the ecosystem state more accurately.
- In-game configurable logging: adjust CoreLib log verbosity from quiet to detailed, useful for servers, testing and support.
- Included workstation: adds the PJMods Bench, a modular crafting station for PJ ecosystem content.
- Organized PJ crafting categories: the bench groups recipes into sections like Chests, Pickaxes, Armors, Generators, Ingots and Misc.
- Bench upgrades: the PJMods Bench supports progression levels with crafting time reduction.
Important
- If you use multiple PJ mods, CoreLib is an essential dependency.
- It must be installed and enabled for other PJ mods to work as expected.
