We are going to start off by defining the user interface (UI) that will wrap the AR components. First, we will define a custom control that we will use as a placeholder for injecting an UrhoSurface that will contain the AR components. Then, we will add this control in a grid that will contain some statistics about how many planes we have found and how many boxes are active in the world. The goal of the game is to find boxes in AR using your phone and tap on them to make them disappear.
Let's start by defining the custom ARView control.
