This chapter covered the basics of Unity's UI system as it applies to virtual reality games and experiences. Right away we dove into the difficulties, particularly the need to use a custom input module to send messages to Unity's canvas-based UI system.
We were then able to explore the various uses of VR interfaces in both standard square menus and on dynamic objects places throughout the scene. In doing so, we added more complexity to our game mechanics.
In the next chapter, we'll be adding an entirely new feature to our game: audio. Using the Oculus audio tools and the tools built into Unity, you'll add sound effects with realistic spatialization that make the experience even more immersive.
