I'm developing a game for Mac using GameMaker Studio 2, which allows you to add extensions created with another programs. When using Mac OS X, GameMaker needs an extension of type .dylib, which includes the functions you call in GameMaker when you add the extension to your project.
I would like to add some TouchBar functions in my video games, and I already know how to develop apps with Touchbar using Xcode, but the problem is that I have no idea of what I have to do to create a .dylib library so as to use Touchbar functions through GameMaker (I don't even know if something like that is possible). Is there someone who knows how to do this?
