Code a DOOM-like game engine from scratch in C PART I

This is part I of the DOOM-like game engine from scratch tutorial. It introduces the basics of (Pseudo-3D) graphics rendering and movement mechanics. Also concepts such as portals, rendering, world transformations, and others. You can download the source code from here: Some notes to keep in mind about Part I: - we do the minimal required work to get started - code style is not really the focus here - back-to-front rendering (i.e. Painter's algorithm) is a bad idea, it will be revisited in Part II - sorting sectors by their centroids with bubble sort is very inefficient and lacks precision -- it's there just to leave you with a bit more compete solution until part II comes out www: twitter: fb: For more advanced topics and complete courses by a professional lecturer, you can take a look at Pikuma's lectures at
