This text is written for those who only make first steps in programming. The main idea is to show, step by step, how to make a game à la <a href="https://en.wikipedia.org/wiki/Wolfenstein_3D">Wolfenstein 3D</a>. Attention, I am not going to compete with Carmack, he is a genius and his code is stunning. I aim a different goal: I'm using the huge computing power of modern computers to allow my students to create fun projects in very short time (typically few days), without getting stuck in the optimization nightmare. To write a slow code is my intention, it is much shorter and more understandable. While Carmack <a href="https://en.wikipedia.org/wiki/Fast_inverse_square_root">writes 0x5f3759df</a>, I write 1/sqrt(x). We pursue different goals.
