Godot Tutorial: How to read all files in EVERY sub directory (Breadth/Depth first Search)     Hey all, So I was thinking of writing some automated smoke tests in Godot for a project I'm working on and I realized, I don't think I've ever done directory I/O in Godot. - The tools is so well integrated that I've never really had to mess with it yet. - I'm willing to bet many of you guys haven't either. - Don't worry it's easy, lets get into it. You'll learn: - How to read all files in a directory to process however you'd like - How to use Depth First Search - How to use Breadth First Search - The order that both search styles will traverse a tree Code From Tutorial: How to use: - Create a "Node" type of Godot Node    - Note in Video I used Node2D which is OK, but slighly better to use plain Node since no 2D coords etc are needed - Attach this script to that Node: https://gist.github.com/Razzlegames/28dcb74ba
