Build Mode UI

In this chapter, we’ll implement the user interface (UI) that shows during “build mode” to allow the user to buy new towers and sell old towers. Before we begin, let’s outline the functionality we’re going to implement. We’ll go over what will they be able to do in build mode. After this, we’ll do a quick primer of the important components and concepts behind Unity’s UI. We’ll then set up our own UI to look as it should in-game. In the next chapter, we’ll implement the functionality of the UI, tying our buttons to code that handles building and selling towers.
