How to Make a 2D Game in C++ and SDL3
constref
A dense video that builds a side-scrolling platformer in C++ with SDL3 and no engine. It starts with the CMake setup and the window, then adds a game loop, animations, a tile map, gravity, collisions, a camera with parallax backgrounds, shooting and enemies. The code is on GitHub, and the author means it as the base for a custom engine.
What you'll learn
- Setting up SDL3 and SDL_image with CMake
- Writing a game loop with delta time
- Animating sprites and managing state with a finite state machine
- Loading tile maps and handling collision detection and response
- Adding a camera, parallax backgrounds and jumping
- Shooting with reusable bullet objects
