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.

Using a Timeline to activate objects

According to our plan, when the timeline starts, the bird's nest will be hidden (the NestAndEggobject). At the 35-second mark, it becomes enabled. Also, when the nest is first enabled, it should containWholeEgg. Then, at the 80-second mark, it is hidden theHatchedEggis enabled instead. The NestAndEgg game object hierarchy, as shown here, contains the Nest itself, a WholeEgg object, and a HatchedEgg object (which contains the two eggshell halves):

Now, let's add the activation sequence to the Timeline. You can view the results of these and the following steps in the screenshot further down:

  1. With Blackbird Director selected in Hierarchy, drag the NestAndEgg object from Hierarchy into the Timeline Editor window.
  2. A menu will pop up, asking you what type of track to add; choose Activation Track.
  3. Ensure the Timeline units are Seconds, not Frames. Use the gear icon...
