Here, we will create a "Hello, World!+". We will use it to further familiarize you with Unity, beyond the basic layout of the preceding chapter. In an effort to avoid repeating steps, we will build onto this project throughout the rest of the book.

The most basic Unity project is made up of at least one scene. Any new scene will contain a directional light and main camera. The HoloLens uses this camera as the user's point of view, so we will need to make a few changes to the default starting scene to suit our needs.

Here, we will set...
