Book Description

Create your own line of successful 2D games with Unity!

In Detail

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.

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.

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.

What You Will Learn

  • Work with Unity's new 2D workflow and create a 2D scene
  • Set the scene with different types of backgrounds, either static or dynamically using a tileset
  • Bring your character to life through simple animations
  • Understand the core concepts of programming by creating basic code that controls a character and destroys an enemy
  • Create buttons and game controls by using code snippets for input detection
  • Develop five 2D games from genres such as classic arcade, endless runner, rogue-like, physics, and space buddy games
  • Add audio and feedback and deploy your games
