Chapter 15. Sound Spatialization and HUD

In this chapter, we will be adding all the sound effects and the HUD. We have done this in both of the previous projects, but we will do things a bit differently this time. We will explore the concept of sound spatialization and how SFML makes this otherwise complicated concept nice and easy; in addition, we will build a HUD class to encapsulate the code that draws information to the screen.

We will complete these tasks in the following order:

• What is spatialization?

• How SFML handles spatialization

• Building a SoundManager class

• Deploying emitters

• Using the SoundManager class

• Building a HUD class

• Using the HUD class
