How to Make a 2D Game in C++ and SDL3
In this video, I'll take a deep dive into fundamental game development, and build a platformer from the ground up. We don't just present a few SDL functions and call it a gamedev video, we do window management, drawing, game loop, animation, keyboard , collisions, audio, and bunch of other topics, this video is dense! We'll lay the foundation for building our own game engine.
