Detailed Description

Represents a single UFO in the DemoGame.

A UFOSprite is responsible for a UFO's behavior which includes swooping in from the top of the screen, moving towards a CowSprite. If it abducts a CowSprite, it heads back to the top of the screen and disappears.

UFOSprites are responsible for keeping track of a UFO's sounds, images, and states. UFOSprites come in five different types: circle, triangle, square, X, and Z. UFOSprites can be destroyed by a Player making a matching gesture and will reward that Player with 100 points.
