XLib is a Vintage Story mod by Xandu. XLib is a library for Vintage Story mods that adds shared systems for skills, abilities, effects, and their data.
Why this mod is worth installing
This dependency is useful for modders building custom progression or gameplay abilities without creating their own synchronization and data-storage systems.
What XLib adds
XLib works as a behind-the-scenes framework rather than a content mod. By itself it does not add a visible skill tree, new abilities, or gameplay effects; instead, it exposes an interface that other mods can use to register and manage them.
The library handles communication between the server and connected clients, along with saving and loading the related data. It also includes an in-game dialog opened with the O key by default, giving compatible mods a place to present their systems to the player.
