Mobile Game Development with Unity: Build Once, Deploy Anywhere

by Jonathon Manning, Paris Buttfield-Addison

Overview

Do you want to build mobile games, but lack game development experience? No problem. This practical guide shows you how to create beautiful, interactive content for iOS and Android devices with the Unity game engine.

Authors Jon Manning and Paris Buttfield-Addison (iOS Swift Game Development Cookbook) provide a top-to-bottom overview of Unity’s features with specific, project-oriented guidance on how to use them in real game situations. Over the course of this book, you’ll learn hands-on how to build 2D and 3D games from scratch that will hook and delight players. If you have basic programming skills, you’re ready to get started.

• Explore the basics of Unity, and learn how to structure games, graphics, scripting, sounds, physics, and particle systems
• Use 2D graphics and physics features to build a side-scrolling action game
• Create a 3D space combat simulator with projectile shooting and respawning objects, and learn how to manage the appearance of 3D models
