Introduction
In Chapter 4, Particle System and Game Performance, we created a full game of collecting coins by FlyingSpaceship containing sprites, scenes, parallax infinite scrolling background, particle effects, and many more except music. Now we are moving forward to add the most interesting part to the game, which is music. Music and sound effects brings a sense of engagement and fun to the game; no game exists without music. So we will be integrating some cool and awesome background music and sound effects into the FlyingSpaceship game built in the previous chapters. Moreover, we will be enlightening a new technology called iCloud and its framework recently released by Apple. Using iCloud, we can easily and securely store and retrieve the app data like a database from the iCloud, which is provided by Apple.
