Using multiple cameras
Our Unity games must have a least one camera, but we are not limited to using just one. As you will see in Chapter 7, Implementing Our Player Character, we will attach our main camera, or primary camera, to our player character. It will be as if the camera is following the character around the game environment. This will become the eyes of our character. We will play the game through our character's view.
A common use of a second camera is to create a mini-map that can be seen in a small window on top of the game display. These mini-maps can be made to toggle on and off or be permanent/fixed display components. Implementations might consist of a fog-of-war display, a radar showing enemies, or a global top-down view of the map for orientation purposes. You are only limited by your imagination. In Chapter 9, Adding a Heads-Up Display, we will create a mini-map as a radar showing where beetles are in relation to the Cucumber Man's current position.
