Though Unity is basically a three-dimensional engine, it provides several excellent tools to create full two-dimensional games as well. As most indie games are 2D, we think you can take advantage of learning at least the basics of managing sprites in Unity. With this chapter, we aim to make you proficient with sprites, spritesheets, and 2D animation techniques.
Sprites can be defined as 2D images that get animated in a larger scene. Think of any classic 2D platform video game, such as Nintendo's Super Mario Bros. There is a background image (usually static), and there is a character running and jumping across the screen. That character is a sprite.
A sprite is created by importing a texture in the project and setting it as a Sprite type.
