Writing the game

In this section, we will initialize Urho by setting up the camera, lighting, and a renderer. All the remaining code will now be written in the abstract Game class in the WhackABox project (the .NET Standard library project). The camera is the object that determines where objects will be rendered. The AR components take care of updating the position of the camera to virtually track your phone so that any object we render will be in the same coordinate space as what you are looking at. First, we need a camera that will be the viewing point of the scene.
