As an indie or AAA game developer, you want to have your games where your customers are. More and more people buy mobile devices every year and there's no sign of this stopping any time soon. One of the big advantages of the Unity game engine is that it is cross-platform, making it easy to write your game once and then port it to other consoles with minimal changes. However, there are certain features unique to working with mobile devices, which is what this book is about.

Unity 2020 Mobile Game Development will take you on an exploration of how to use Unity when trying to deploy your content to mobile devices. Over the course of the book, we will see how to create a mobile game and then see how to deploy it to both iOS and Android. We will explore how to add input for mobile devices and have the interface adapt to the many different screen sizes that phones have. We'll then look at some ways to monetize our game by discussing Unity's in-app purchase and advertisement systems. We will also learn how to use notifications to keep users coming back to our game. Then, we will see how we can share our game with the world by enabling us to use Twitter and Facebook's SDK. Afterward, we will see how to work with Unity's analytics system and then polish our title in a number of different ways, before putting it on the Google Play and iOS app stores. Finally, we will also learn how to use Unity's new AR Foundation framework, which allows you to build future-proof AR apps.

If you are a Unity game developer and want to build mobile games for iOS and Android, then this is the book for you. Previous knowledge of C# is helpful, but not mandatory.

, Building Your Game , covers the creation of a simple project in Unity, which we will be modifying over the course of this book to make use of features commonly seen in mobile games. This chapter will also serve as a refresher for some fundamental concepts when working in Unity.
