Yup, YAGE. Yet Another Game Engine. A toy engine, mind you, never intended for general release or something people will ever require support with. It is something I use to experiment on, learn new things, practice, prototype and eventually, try and ship a game or two with.
This code started during my first days in university. The first iteration looked like this: Youtube link.
Next to no programming experience and it shows in the parts of code that survived since then (all the SceneNode and Resource stuff). Started with a lot of OOP and "Clean Code" with C++98 and currently developed using as much DoD as possible (basic structs and enums, inheritance mostly for interfaces or restrictions {NonCopyable, NonMovable, etc}) but with C++20 for ease of use (constexpr and concepts over templates, threading and filesystem builtin, lambdas over function pointers etc).
It got me through learning old-school OpenGL (1.x, 2.x), core GL (3.x, 4.x) and some AZDO techniques (indirect rendering, bindless textures, persistently mapped buffers, etc). Currently using it to learn Vulkan 1.3 (why would I learn about framebuffers, subpasses and renderpasses now? Maybe for mobile, but I don't see myself doing that now, and if I did, I'd learn that as required).
The reason it's published on GitHub are:
- so I can store the code somewhere central and keep track of changes.
- if people do as I do and search for various things (functions, enums, etc) on GitHub, maybe my code can help.
- if anyone is struggling with solving a problem that I already banged my head against, feel free to get inspired by it.
If you plan to use any parts of this code in a commercial product, a couple of things:
- Are you sure?
- Please let me know as I'm curious to see where and why and also, I'd highly appreciate it.
- Clone with recursive submodules (e.g. git clone --recurse-submodules). Needed for vcpkg.
- Open the root folder in VSCode (with CMake and C++ extensions installed).
- Under CMake Project Status view, select the desired Configure preset followed by the desired Build preset.
- Build and Run as needed.
- Works on both Windows and Linux.
- Engine / Game builds:
- Open the root folder in Visual Studio (with CMake tools installed).
- Select the desired preset from the Build Preset dropdown.
- Build and Run as needed.
- Project Manager:
- Same as above (VS/VSCode) but with the ProjectManager subfolder as a root.
- Alternatively. RUN.bat will attempt to build a release version and launch that.
- The Project Manager has an option to launch Visual Studio with the proper path set.
- Only tested the VSCode steps outlined above.

I did try to comply with all of them, but I may have missed something.
