It's really as the name says -- I'm learning how to build a game engine. The goal here is to learn C++14, RAII, graphics programming, and cross-platform development in C++. If I'm very, very unlucky, I might also have to brush up on my calculus and linear algebra.

1. DirectX SDK
2. Visual Studio 2015
3. Premake 5 (PS> scoop install premake5)

1. XCode
2. GLFW ($ brew install glfw)
3. Premake5 ($ brew install premake5)

(Assuming you've used vcvars_all to place Visual Studio/MSBuild on your PATH)

PS> premake5 vs2015
PS> msbuild build/GameExperiment.sln

alternatively, to open in VS2015

PS> premake5 vs2015
PS> devenv build/GameExperiment.sln

$ premake5 xcode4
$ xcbuild build/GameExperiment.xcworkspace

alternatively, to open in XCode

$ premake5 xcode4
$ open build/GameExperiment.xcworkspace

Q: Why are you building an engine? Why not use Unreal/Unity/Frostbyte/etc

A: If I were actually making a game, I would. But this is for learning how engines like the ones mentioned work, as well as other low-level graphics concepts.

Q: Are you actually building a game? Will it be on Steam?

A: Not really, and no.

Q: Do you accept pull requests? Can I contribute?

A: Yes! I do ask, however, that any pull requests highlight what they add, or fix, and why. That way, people who come along later can learn from my mistakes :p

Q: What platforms does it run on?

A: I test Windows 10 and OSX El Capitan. If it runs elsewhere, awesome!

Q: What graphics pipeline do you use?

A: DirectX 11 on Windows and OpenGL 3.2 on OSX. Eventually, I might look and using DirectX 12 or Vulkan (respectively), but for now that's entirely too low-level for my skillset.

Q: What scripting engine are you using?

A: For now, none. I'm investigating ChakraCore, LuaJIT, and Stackless Python.

Q: What license is this under?

A: Check below
