How do you get the absolute project path?
eg: C:\Users\Name\Desktop\Project…
There is documentation to get different folders, datafolder even to the engine itself, but nothing about the project path
ProjectSettings.globalize_path("res://")
See:
Naturally, this is usually only helpful when used by a tool script or plugin or maybe for debugging purposes. When the game is released then the res:// folder might as well be inside a packed file.
