About this project
What does UnionLib add?
DESCRIPTION
This is an API mod, so it provides nothing for users and is intended for developers to use. This mod only does two things, first is making developing multi-loader mods as simple as possible and the second is a configuration system that's very intuitive to use and lacks complexity. I'm sure that nothing this mod provides hasn't been done before, especially the configuration system. Still, if you want to develop your next mod or integrate your current mod with UnionLib, then you should take a look at this resource. I'm sure it'll prove handy.
SUPPORT
If you want to support me, you can do so by either hiring me on Fiverr, subscribing on Patreon or buying my game on Epic Games or Itch.io. It's a racing game that I'm sure you'll have fun in if you're into that. If you have, thank you very much. Thanks to you, I'm able to keep this up.
