UniverseLib is a library for making plugins which target IL2CPP and Mono Unity games, with a focus on UI-driven plugins.
It was developed for personal use so that my UnityExplorer tool and my Config Manager plugins could use a shared environment without overwriting or conflicting with each other, but I made it available as a public tool cause why not.
Documentation and usage guides can currently be found on the Wiki.
The Analyzers package contains IDE analyzers for using UniverseLib and avoiding common mistakes when making universal Unity mods and tools.
