Preface
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 2017 Mobile Game Development will take readers 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 see some ways to monetize our game by discussing Unity's in-app purchase and advertisement systems. 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.
What this book covers
Chapter 1, 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.
Chapter 2, Setup for Android and iOS Development, will show the setup required to deploy a project to both iOS and Android mobile devices, by installing the Java and Android SDKs for Android and configuring Xcode for iOS.
Chapter 3, Mobile Input/Touch Controls, shows a number of ways in which input can work on mobile devices. Starting off with mouse events, we will dive into recognizing touch events and gestures, as well as how to use the accelerometer and accessing information using the Touch class.
Chapter 4, Resolution Independent UI, discusses how to build the user interface for our game, starting with a title screen, and then build the other menus that we will want to use for our future chapters.
Chapter 5, Advertising Using Unity Ads, shows how to integrate Unity's Ad framework into our project and learn how to create both simple and complex versions of advertisements.
Chapter 6, Implementing In-App Purchases, talks about how to integrate Unity's In-App Purchase (IAP) system into our project and take a look at how to create an IAP that is used for consumable content as well as permanent unlocks.
Chapter 7, Getting Social, shows how to integrate social media into your projects, starting off with sharing high scores using Twitter and then taking a look at how we can use the Facebook SDK in order to display our player's name and profile picture while inside our game.
Chapter 8, Using Unity Analytics, covers some of the different ways that we can integrate Unity's Analytics tools into our projects, tracking custom events as well as using remote settings to allow us to tweak gameplay without having people redownload the game from the store.
Chapter 9, Making Your Title Juicy, introduces the concept of making games juicy with different ways that you can integrate features of juiciness into our projects, including tweening animations, materials, post-processing effects, and adding particle effects.
Chapter 10, Game Build and Submission, goes over the process of submitting our game to the Google Play or iOS App Store, with tips and tricks to help the process go smoother.
What you need for this book
Throughout this book, we will work within the Unity 3D game engine, which you can download from http://unity3d.com/unity/download/. The projects were created using Unity 2017.2.0f3, but the project should work with minimal changes in future versions of the engine.
For the sake of simplicity, we will assume that you are working on a Windows-powered computer when developing for Android and a Macintosh computer when developing for iOS. Though Unity allows you to code in C#, Boo, or UnityScript, for this book we will be using C#.
Who this book is for
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 required.

Building Your Game
As we start off on our journey building mobile games using the Unity game engine, it's important that readers are familiar with the engine itself before we dive into the specifics of building things for mobile platforms. Although there is a chance that you've already built a game and want to transition it to mobile, there will also be readers who haven't touched Unity before, or may have not used it in a long time. This chapter will act as an introduction to newcomers, a refresher for those coming back, and will provide some best practices for those who are already familiar with Unity.
In this chapter, we will build a 3-D endless runner game in the same vein as Imangi Studios, LLC's Temple Run series. In our case, we will have a player who will run continuously in a certain direction, and will dodge obstacles that come in their way. We can also add additional features to the game easily, as the game will endlessly have new things added to it.
Chapter overview
Over the course of this chapter, we will create 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. While you may skip this chapter if you're already familiar with Unity, I find it's also a good idea to go through the project so that you know the thought processes behind why the project is made in the way that it is, so you can keep it in mind for your own future titles.
Your objectives
This chapter will be split into a number of topics. It will contain a simple, step-by-step process from beginning to end. Here is the outline of our tasks:
Project setup
Creating the player
Improving scripts using attributes
Having the camera follow the player
Creating a basic tile
Making the game endless
Creating obstacles
Setting up the project
Now that we have our goals in mind, let's start building our project:
To get started, open Unity on your computer. For the purpose of this book, we will use Unity 2017.2.0f3, but the steps should work with minimal changes in future versions.
From startup, we'll opt to create a new project by clicking on the
New
button.
Next, under
Project name*
put in a name (I have chosen
MobileDev
) and make sure that
3D
is selected. If
Enable Unity Analytics
is enabled (the check to the left of it says
On
), click on the
Enable Unity Analytics
button again in order to disable it for the time being; we will add it ourselves later on when we go through
Chapter 5
,
Advertising with Unity Ads
. Afterwards, click on
Create project
and wait for Unity to load up:
After it's finished, you'll see the Unity Editor pop up for the first time:
If your layout doesn't look the same as in the preceding screenshot, you may go to the top-right section of the toolbar and select the drop-down menu there that reads
Layers
. From there, select
Default
from the options presented.
