When working with sprites, it is easier and more convenient to use a separate image (otherwise known as a texture file) for each character. However, the image will usually have a lot of empty space surrounding it, and this takes up video memory during runtime (when the game is running), which impacts performance. In order to reduce the wastage and optimize performance, we make use of texture atlasing. A technique called draw call batching that Unity and other engines use also helps to improve the frame rate. It too requires texture atlasing particularly for PC games, whereby a complex 2D scene would probably become CPU-bound.

Overview of this book
<p>If you are looking for a guide to create 2D games using Unity, look no further. With this book, you will learn all the essentials of 2D game development by creating five real-world games in a step-by-step manner throughout the course of this book.</p>
<p>Starting with a blank scene, you will learn all about the new Unity 2D toolset, which will enable you to bring your scene to life. You will create characters, make them move, create some enemies, and then write code to destroy them. After figuring out all the necessities of creating a game, this book will then assist you in making several different games: games with collision, parallax scrolling, Box2D, and more.</p>
<p>By the end of this book, you will not only have created several small games, but you will also have the opportunity to put all your new-found knowledge into creating and deploying a larger, full game.</p>
