Develop a Sprite and Platform Game - Unity 4 Game Development - page 3

We will use a 2D character sprite sheet (which is the set of many small images in a large
image, as shown in the previous figure), and the new 2D feature in Unity to create our 2D
character. The new 2D feature in Unity helps us to manage the sprite sheet and set up the
animation for each character's movement without writing any script.
