Complete Virtual Reality and Augmented Reality Development with Unity

By: Jesse Glover, Jonathan Linowes

Overview of this book

Unity is the leading platform to develop mixed reality experiences because it provides a great pipeline for working with 3D assets. Using a practical and project-based approach, this Learning Path educates you about the specifics of AR and VR development using Unity 2018 and Unity 3D. You’ll learn to integrate, animate, and overlay 3D objects on your camera feed, before moving on to implement sensor-based AR applications. You’ll explore various concepts by creating an AR application using Vuforia for both macOS and Windows for Android and iOS devices. Next, you’ll learn how to develop VR applications that can be experienced with devices, such as Oculus and Vive. You’ll also explore various tools for VR development: gaze-based versus hand controller input, world space UI canvases, locomotion and teleportation, timeline animation, and multiplayer networking. You’ll learn the Unity 3D game engine via the interactive Unity Editor and C# programming. By the end of this Learning Path, you’ll be fully equipped to develop rich, interactive mixed reality experiences using Unity. This Learning Path includes content from the following Packt products: • Unity Virtual Reality Projects - Second Edition by Jonathan Linowes • Unity 2018 Augmented Reality Projects by Jesse Glover

Chapter 4. Gaze-Based Control

Right now, our diorama is a third-person virtual reality experience. When you go into it, you're like an observer or a third-person camera. Sure, you can look around and add controls that let you move the camera's viewpoint. However, any action in the scene is from a third-person perspective.

In this chapter, we'll pretty much stay in the third-person mode, but we'll get a little more personally involved. We will explore techniques that can be used to control objects in your virtual world by looking and staring. Our character, Ethan, will be under your control, responding to where you look. Furthermore, we'll start programming the Unity scripts. Along the way, we will discuss the following topics:

  • Adding AI (short for artificial intelligence) and NavMesh to our third-person character, Ethan
  • Unity programming in C#
  • Using our gaze to move a 3D cursor
  • Shooting and killing Ethan, the zombie, to good effect
