In this lesson, I guide you through using c ++ function pointer and lambdas to store and invoke callbacks from anywhere in your applications. This is demonstrated through a mock Input Manager that you might find in a game engine implementation. We start off by mocking out the manager, support accepting c ++ function pointers and then enhancing the class to accept a wider set of functions using std::function and lambdas.

In this lesson, we bootstrap some game engine systems and provide an entry point to our client applications. By the end we have a fully functional window system and a functional basic game loop in our game engine. Next lesson, we'll be adding Vulkan to our project and clearing the window to a colour!
