About CoreLib
From ThunderstoreA library that makes modding Core Keeper easier
CoreLib
A modding library for Core Keeper. Provides features that makes modding Core Keeper easier.
WARNING! Version 2.0.0 contains breaking changes. Make sure to update ALL of your mods before proceeding!
List of features
- Custom items, blocks, enemies, NPC, etc.
- Adding items using JSON
- Easier access to Rewired input system, localization
- Custom chat commands
And much more!
Note on multiplayer and save compatibility
If you are playing with friends MAKE SURE to sync your CoreLib.ModEntityID.cfg and CoreLib.TilesetID.cfg config files. If anything inside does not match you WILL encounter issues connecting, missing items, and errors.
The same applies if you are loading a save of another user. If your ID's don't match the ID's save was created with, the save will load corrupted.
I recommend any mods adding custom content warn users about this on their page.
This might get improved later, but right now this is best that you can do.
