Looking at this:
https://docs.godotengine.org/en/stable/classes/class_engine.html#class-engine-method-get-idle-frames
Does this give me the number of frames processed since the game started? Or does it only count frames in which some qualification for "idle" is met?
I'm trying to set up a thing where I need the total number of frames passed since the game started, and if possible I wish to use built-in stuff rather than making a counter on my own.
