In GDscript, I can write save files to user://foo/bar.txt, and they show up in the appropriate location. For C#/Mono builds, how do I access this path?
Turns out there’s an (undocumented?) API for this: Godot.ProjectSettings.GlobalizePath("res://foo/bar.txt") resolves to the proper location.
Godot.ProjectSettings.GlobalizePath("res://foo/bar.txt")
