📋 About This Mod
JötunnLib is a modding library for Valheim, with the goal of making the lives of mod developers easier. It's a centralized API to allow mod developers to easily add custom items, recipes, prefabs, and more to the game, working for both servers and clients.
On its own, JotunnLib makes very few changes to the game. It adds:
-
[]A "clear" console command
[
]A better "help" console command (which also shows help for mod console commands)Any other changes are left up to mod developers to implement, in order to have as few conflicts with other mods as possible.
Important note about naming
Please note, "JotunnLib" (JL), and "Jötunn, the Valheim Lib" (JVL) are NOT the same thing. JotunnLib is this library here, and JVL is the new and improved version of this library and is the outcome of the merger discussed below.
❗❗ Deprecation notice ❗❗
JotunnLib is no longer under active development and has not been for quite some time. If you are looking to create a mod, please use Jötunn, the Valheim Library instead! If you are installing JotunnLib as a dependency for any mods, go ahead, but please bug the mod author to make the switch to JVL instead :)
The only updates that will be made to JotunnLib going forward will be to fix any compatibility issues or game-breaking issues - no new features will be added.
Jötunn, the Valheim Library is the direct successor to JotunnLib. It was originally created by the teams behind ValheimLib and JotunnLib as a means to unify the Valheim modding community, and it has evolved into a massive project with many contributors from the community.
Thank you again to all the developers and players who tried out and used the original JotunnLib ❤️
