This is a "template" project for creating C# DLLs for GameMaker!
Intended to be copied via copyre, like
copyre GMSDLL.cs MyExtension GMSDLL
The project is set up with DllExport to generate unmanaged wrappers for functions and GmxGen in post-build step to auto-update functions in GM extensions.
export/ folder contains sample scripts for re-generating Local Asset Packages without going through GameMaker UI, along with a sample script for uploading releases to itch.io.
Caveat: it is unclear whether and how to use this for non-Windows.
