I might be the most excited about this video. I really wanted to learn how the original Doom game engine works. l spent a long time learning the basic concepts but created the code myself from scratch and how I wanted to design it. You can follow along or convert this code to any other programming language since I kept it simple in C that draws a pixel at x and y coordinates.
Let me know if you enjoy this series! Thank you for all your great ideas and I hope to see what you make from this tutorial series. Send me a link so I can share it in part 2!
