For our regular monthly tutorial nights, we're basing our teaching on the wonderful series by AJ's Learning Lab, Godot FPS Tutorial - Learn Godot by making Wolfenstein 3D.

He has made the assets he uses freely available (please consider donating) here: https://ajslearninglab.itch.io/boganstein-3d-learn-godot-4-with-wolfenstein-3d/

All the code we use is available on AJ's Learning Lab github - https://github.com/AJsLearningLab/GodotFPS

1. Download Godot from https://godotengine.org/download/ and install it (it's available on all platforms)
2. Download the assets from AJ's Learning Lab here: https://ajslearninglab.itch.io/boganstein-3d-learn-godot-4-with-wolfenstein-3d/

Goal: Learn about Godot, create a world/room (floor and walls)
