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.

Building interactive VR experiences with C#

So far, we have added interactions to our scene just by using Unity’s Animation system without writing a single line of code. In the next sections, you will learn how you can use scripting with C# to add even more complex breaths of air into your GameObjects and scene.

The first question we are going to answer is this: when do we need to write C# code for our animations and interactions?

Understanding when to use C# for animations and interactions

It’s important to understand that Unity’s animation and animator systems and the use of C# scripting are not mutually exclusive. They are often used together, with the animator controlling predefined animations and C# adding interactivity based on user input or other game events.

In the previous section, we rotated and scaled cars based using Unity’s animation and animator systems. These systems are primarily used to create predefined animations. We can divide...
