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 from the previous chapter, using C# programming for basic scripting, and explore several software design patterns for user input. We will discuss the following topics:
- Polling for input device data
- Using scriptable data objects for storing and...
