Buttons provided by Unity’s UI system are graphical objects that preutilize the Event System we covered in the last chapter. When a Button is placed in a scene, it automatically has components added to it that allow the player to interact with it. This makes sense because the whole point of a Button is to interact with it. Let’s explore how to add and utilize buttons in our games.

In this chapter, we will discuss the following topics:

• Creating UI Buttons and setting their properties
• How to set button transitions that make the button change appearance when it is highlighted, pressed, or disabled
• How to use invisible button zones to allow large tapping areas
• Navigating button selection on screen with the keyboard or joystick
• How to create an onscreen button that looks like it is physically being pressed
• Loading scenes with a button press
• Creating Button Transition Animations
