Rodney Lab🖥️ C++ Game Development Libraries
In this post, we look at a couple of C++ game dev libraries. Godot and Unreal Engine, among others, allow you to create fully-featured games with fantastic lighting using in-built editors. When it comes to learning game development, as well as quick prototyping, a lightweight alternative is often preferable.
Raylib is a lightweight C/C++ game development framework, ideal for prototyping. We see some resources for getting up-to-speed with Raylib, using C++ in this post.
We will also take a peek at Flecs, a C/C++ entity component system, providing access to a modern, composition over inheritance approach.
Raylib and Flecs pair well, and both support compilation to WebAssembly (WASM), which is brilliant for prototyping, letting you share your work on the web. That is with no need for your audience to install apps in order to see your work.
Let me know if you find the post useful, and of course, if you would like to see similar content covering other C++ tooling.
☀️ Raylib Getting Started Resources
Simple, easy-to-use game development library.
Raylib 5’s release, last year, marked the tenth anniversary of the Raylib 1.0 release. Over that period, the library has been battle-tested and built up a community, which is great for finding content on getting started.
Raylib uses OpenGL, has full 3D support, you can develop with it on Linux, macOS and Windows, and you can also compile your game to WASM using Emscripten, making it quite accessible. Set up your Raylib project with CMake to make it accessible to developers working on different platforms.
The quickest way to get going with Raylib in C++ is to clone a CMake template repo, and get a copy of the Raylib Cheat Sheet (also available as a PDF). The Raylib Cheat Sheet is a list of all the functions that the API exposes, great for poking around and modifying demo code for learning purposes.
There are Rust and Zig Raylib bindings, though if you prefer working in Rust, you might consider Macroquad, which was inspired by Raylib.

💪🏽 Flecs Getting Started Resources
Fast and lightweight ECS.
Entity Component Systems offer an alternative game data storage pattern, to a fully object-oriented approach. The ECS approach can be more maintainable as well as performant. Though not needed for all games, when you do want an ECS, you will want something performant, with a small footprint, which is where Flecs comes in.
Flecs compiles to WASM, using Emscripten, letting you deploy game demos as web pages. It has fantastic documentation, and you can see dozens of examples in C as well as C++ in the Flecs GitHub repo.
An alternative, popular C++ ECS is EnTT, which is used in Minecraft, among other games.

Other C++ Game Dev Tooling
Of course, there is other C++ game-dev related tooling, alternative game frameworks to Raylib that you might consider are:
For creating a game backend, or just displaying diagnostics, on-screen during development, Dear ImGui is also popular.
🙌🏽 C++ Game Dev Libraries: Wrapping Up
In this C++ game dev libraries, we had a look at some C++ game dev tooling and the features offered. More specifically, we saw:
- why you might consider Raylib for prototyping a game;
- links to content for getting started with the Flecs ECS; and
- some alternative C++ game frameworks and ECSs.
