The basic building block for making things with Pixi is an object called a sprite. Sprites are just images that you can control with code. You can control their position, size, and a host of other properties that are useful for making interactive and animated graphics. Learning to make and control sprites is really the most important thing about learning to use Pixi. If you know how to make and display sprites, you’re just a small step away from starting to make games or any other kind of interactive application.
