Overview of this book

The drastic surge in the demand for XR development has led to an imminent need for comprehensive resources, learning material, and overall know-how in this area. This one-stop resource will ensure that professionals venturing into XR development can access all XR-related techniques to build appealing XR applications, without relying on Google every step of the way. This book is your guide to developing XR applications with Unity 2021.3 or later versions, helping you to create VR, AR, and MR experiences of increasing complexity. The chapters cover the entire XR application development process from setting up an interactive XR scene using the XR Interaction Toolkit or AR Foundation, adding physics, animations, continuous movement, teleportation, sound effects, and visual effects, to testing and deploying to VR headsets, simulators, smartphones, and tablets. Additionally, this XR book takes you on a journey from the basics of Unity and C# to advanced techniques such as building multiplayer applications and incorporating hand- and gaze-tracking capabilities. By the end of this book, you'll be fully equipped to create cutting-edge XR projects for engaging individual, academic, and industrial use cases that captivate your audience.

Adding interactivity to our AR menu application

To infuse life into our currently modest AR scene, we must incorporate some C# scripts into our project. This key step will empower the users of our AR app, allowing them to interact with our imported food prefabs dynamically and engagingly.

In the next section, you will get an overview of the short but decisive Food script.

Adding the Food script to the scene

Before we dive into scripting, let’s first organize our project workspace so that we can work more efficiently by finding the needed components quickly.

Start by adding a new folder to the Assets directory in the Project window. Simply right-click and select Create | Folder. Rename this folder Scripts and enter it. Right-click in this empty folder and select Create | C# Script to create a script called Food. After double-clicking on this script, it should be opened in your preferred integrated development environment (IDE).

The Food script defines a custom...
