This certainly has been a very long chapter just to add a background to our scene, but working out how each scene will work is a crucial design element for the entire game; you have to pick a pattern that works for you and your end result once, as changing it can be very detrimental (and a lot of work) in the future.
In this chapter, we covered the following:
Some more practice with the Sprite editor and sprite slicer including some tips and tricks when it doesn't work automatically (or you prefer to slice it yourself)
Some camera tips, tricks, and scripts
An overview of Sprite Layers and Sprite Sorting
Defining boundaries in scenes
In the next chapter, we will cover the basics of the UI system that was implemented in Unity 4.6.
