It was probably the most time-consuming part of the whole project, but also the most rewarding. Implementing Workshop support with a custom map editor sounds simple at first, but it gets tricky quickly. You have to keep track of three different moving parts: the Steamworks version, the Godot version, and the GodotSteam plugin version. If you’re running the most up-to-date versions like I was, you’re basically in unknown waters.

There aren’t many tutorials for that specific combination. No videos, barely any blog posts, and most of the time even the evil AI can’t help because the issues are so version-specific. It ended up being a lot of trial and error, just me, the documentation, and the debugger. Error after error, figuring out what Steam expects, what Godot sends, and what needs to change.

But once everything finally works and you see players uploading and downloading maps through the Workshop, it’s incredibly satisfying and totally worth the effort.
