W GRIFFPATCH! I decided to learn 3D Raycasting on Scratch. It's because I had a great idea for a game (I won't reveal what it is because I'm not sure I'm serious about it yet.). Arrow keys to move forward. backward, and turn. A and D keys to strafe. I'd also advise setting the RES to 4. Do what ever you want with the FOV. That Hairy Thing playing in the background. To see the song: https://scratch.mit.edu/projects/1198418734/ Enjoy!
Thanks to Griffpatch for his tutorials on Youtube.
