Build Games in the Browser with C++, Lua & WebAssembly

Learn C++20, Lua, and WebAssembly by building a complete 2D game engine that runs in the browser.

What you’ll learn
Compile C++ and Lua to WASM using Emscripten
Build a modular 2D game engine from scratch
Add Lua scripting, rendering, input, and asset management
Make real playable browser-based games

Requirements
You should be comfortable writing basic C++ (functions, pointers, classes) — no WASM or Lua knowledge needed.

Description
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 EnTTPhysics and collisions powered by Box2DLua scripting for flexible and dynamic gameplay logicOpenGL rendering for efficient graphicsSDL2 for input, windowing, and audioHot-reloadable assets and a modular architecture ready for expansionBy 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 EmscriptenHow to use SDL2 and OpenGL for cross-platform rendering in the browserHow to build an Entity Component System (ECS) with EnTTHow to add physics using Box2DHow to embed and use Lua for scripting gameplayHow to organize your game engine architecture cleanly and efficientlyHow to create real browser-based 2D games with C++ performanceTechnologies Used:C++20WebAssembly (WASM)EmscriptenSDL2OpenGLBox2DLuaEnTT (ECS)Who This Course Is For:C++ developers who want to bring their games to the webGame developers interested in building their own 2D engineProgrammers who want to learn Emscripten and WebAssembly in a real-world projectAnyone who wants to combine native performance with web deploymentWhy 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.

Who this course is for
Whether you’re a hobbyist or aspiring engine developer, this course gives you real, low-level skills to create and extend your own games and tools.
