Sadly this seems like it is already out of date. I tried following the tutorial.
the plugins folder didn't exist in the git repository.
The godot project wouldnt run. Seems lots of functions were possibly deprecated? The main initial issue is godot hated. "var dir = DirAccess.new()" seems you cant create a DirAccess that way anymore in godot?
Hi! Thanks for taking an interest in my app!
I suspect you're using Godot 4 which is why you're getting those deprecation issues.
You need to use the specific version of godot outlined in the tutorial. It does provide a link to the specific versions archive. (Should be approx. 3.5.x if I remember correctly)
Since I've left this one out in the cold for a while I'm going to bring it up-to-spec with my newer apps and port it over to godot 4 starting in the new year.
Hopefully I've solved your issue but do reach out if you have any other questions :)
