Building the AR Catch scene

The build up is over; we are finally here: creating the action scene where the players bravely catch the monster. Also, this will be our introduction to incorporating AR into our game. There is lots to do to get this all completed by the end of the chapter, so let's get going. We will start by creating a new Catch scene:

1. Create a new scene by selecting menu item File | New Scene. Then, select File | Save Scene As... from the menu. In the Save scene dialog, enter the name of Catch and click on the Save button.
2. From the menu, select GameObject | Create Empty. Rename the new object CatchScene and reset its transform to zero in the Inspector window.
3. In the Hierarchy window, drag and drop the Main Camera and Directional Light objects on to the CatchScene object, to reparent them.
4. From the menu, select GameObject | UI | Raw Image. This will create a Canvas object with the Raw Image as a child. Select and rename the RawImage object to Camera_Backdrop in the Inspector window...
