Unity 2020 Virtual Reality Projects - Third Edition

By: Jonathan Linowes

Overview of this book

This third edition of the Unity Virtual Reality (VR) development guide is updated to cover the latest features of Unity 2019.4 or later versions - the leading platform for building VR games, applications, and immersive experiences for contemporary VR devices. Enhanced with more focus on growing components, such as Universal Render Pipeline (URP), extended reality (XR) plugins, the XR Interaction Toolkit package, and the latest VR devices, this edition will help you to get up to date with the current state of VR. With its practical and project-based approach, this book covers the specifics of virtual reality development in Unity. You'll learn how to build VR apps that can be experienced with modern devices from Oculus, VIVE, and others. This virtual reality book presents lighting and rendering strategies to help you build cutting-edge graphics, and explains URP and rendering concepts that will enable you to achieve realism for your apps. You'll build real-world VR experiences using world space user interface canvases, locomotion and teleportation, 360-degree media, and timeline animation, as well as learn about important VR development concepts, best practices, and performance optimization and user experience strategies. By the end of this Unity book, you'll be fully equipped to use Unity to develop rich, interactive virtual reality experiences.

Interacting with Your Hands

When we're in a virtual world with all this cool stuff, it is in our nature to try to reach out and touch something. While the gaze-based selection that we used in the previous chapter is a good first step for interacting with virtual scenes, most people intuitively want to use their hands. Most VR devices provide a hand controller to select, grab, and interact with virtual objects in the scene.

In this chapter, we introduce practices for capturing user input in Unity, illustrating how to use them in a simple VR scene. Everyone loves balloons, so in this project, we will make balloons. We may even pop a few. We will continue with our work in the previous chapter, using C# programming for basic scripting, and exploring several software design patterns for user input. We will discuss the following topics:

  • Polling for input device button presses
  • Invoking and subscribing...
