I want to implement a threaded loading component into my game. I am currently saving all my settings and other level files as bytes externally (meaning not in the res:// folders), as I want to be able to export files and send them to others, so they can use them as well. There is the ResourceLoader.load_threaded_request() method, but that only returns Resources and not PackedByteArrays. As far as I can tell, there is only the FileAccess.get_file_as_bytes() method for importing byte files, which has to run in the main thread (and thus blocking it until the load is complete). Does someone know if I am missing some method here?
EDIT: I have put my fix for this into the comments
Have you tried asking this question in the Godot discord? The engine devs hang out there, might be able to give you a hand.
