Bring the power of modern C++20, OpenGL, and SDL2 straight to the browser with WebAssembly, and build your own 2D game engine from the ground up. In this course, you’ll learn how to combine native C++ performance with the accessibility of the web, using Emscripten to compile your engine to WASM so it runs directly in any modern browser.
You’ll go beyond just drawing sprites — we’ll architect a real engine with:
- Entity Component System (ECS) using EnTT
- Physics and collisions powered by Box2D
- Lua scripting for flexible and dynamic gameplay logic
- OpenGL rendering for efficient graphics
- SDL2 for input, windowing, and audio
- Hot-reloadable assets and a modular architecture ready for expansion
By the end of the course, you’ll have built a complete, browser-based game framework capable of running complex 2D games — all coded in modern, clean C++20 and easily extended through Lua scripts. We’ll start with a simple Tetris-style game, then evolve into a platformer using physics, tilemaps, and real scripting control. Along the way, you’ll learn core engine design patterns, modern C++ techniques, and real-world practices for cross-compiling and optimizing games for the web.
What You’ll Learn:
- How to compile modern C++20 to WebAssembly using Emscripten
- How to use SDL2 and OpenGL for cross-platform rendering in the browser
- How to build an Entity Component System (ECS) with EnTT
- How to add physics using Box2D
- How to embed and use Lua for scripting gameplay
- How to organize your game engine architecture cleanly and efficiently
- How to create real browser-based 2D games with C++ performance
Technologies Used:
- C++20
- WebAssembly (WASM)
- Emscripten
- SDL2
- OpenGL
- Box2D
- Lua
- EnTT (ECS)
Who This Course Is For:
- C++ developers who want to bring their games to the web
- Game developers interested in building their own 2D engine
- Programmers who want to learn Emscripten and WebAssembly in a real-world project
- Anyone who wants to combine native performance with web deployment
Why Take This Course:
Most WebAssembly tutorials stop at “Hello World.” In this course, you’ll build something real — a fully functional 2D game engine capable of running in the browser. You’ll understand every layer: from C++20 compilation, ECS architecture, and physics integration, to scripting, rendering, and deployment. This is modern game engine design for the web, taught step-by-step, with clean, maintainable C++ and production-quality techniques.
