Overview of this book

Augmented Reality brings with it a set of challenges that are unseen and unheard of for traditional web and mobile developers. This book is your gateway to Augmented Reality development—not a theoretical showpiece for your bookshelf, but a handbook you will keep by your desk while coding and architecting your first AR app and for years to come. The book opens with an introduction to Augmented Reality, including markets, technologies, and development tools. You will begin by setting up your development machine for Android, iOS, and Windows development, learning the basics of using Unity and the Vuforia AR platform as well as the open source ARToolKit and Microsoft Mixed Reality Toolkit. You will also receive an introduction to Apple's ARKit and Google's ARCore! You will then focus on building AR applications, exploring a variety of recognition targeting methods. You will go through multiple complete projects illustrating key market sectors including business marketing, education, industrial training, and gaming. By the end of the book, you will have gained the necessary knowledge to make quality content appropriate for a range of AR devices, platforms, and intended uses.

Preface

Creating an instruction data model


Now that we have a UI and a controller, we're ready to round out our MVC architecture and define the data model. We will first define an InstructionStep class that represents the data for one of the instructions steps. Then we'll define an InstructionModel, which has the list of steps used in the app.

InstructionStep class

We'll get started by creating a new C# script named InstructionStep, which will basically be a data structure or container for a row of data from our spreadsheet (in CSV format), including fields the for title, body text, image, and video.

  1. In the Project Assets/HowToChangeATire/Scripts folder, right-click and create a new C# Script and name it InstructionStep.
  2. Open it for editing.

When Unity creates a new script it uses a default template for a typical object class derived from MonoBehaviour. We want this to be just a simple object and do not want it to be a MonoBehaviour (and do not need the Start/Update functions).
