Mastering iOS Game Development

By: Peter Ahlgren, Miguel DeQuadros

Overview of this book

iOS is an operating system for Apple manufactured phones and tablets. Mobile gaming is one of the fastest-growing industries, and compatibility with iOS is now becoming the norm for game developers. SpriteKit is part of the native SDK from Apple, and enables developers to make simple entry into game development without unnecessary overhead and a long learning process. SpriteKit also provides other functionality that is useful for games, including basic sound playback support and physics simulation. In addition, Xcode provides built-in support for SpriteKit so that you can create complex special effects and texture atlases directly in Xcode. This combination of framework and tools makes SpriteKit a good choice for games and other apps that require similar kinds of animation. Become a master in iOS game development through this fast and fun guide! In the beginning, we’ll tell you everything you need to plan and design your game. You’ll then start developing your game through step-by-step instructions using the various built-in technologies of Xcode. From there on, we discuss how to deploy your game to the iOS App Store, as well as monetizing it to make more revenue. You will also learn advanced techniques to improve your game playing experience, including better multi-tasking, improved performance optimization, battery management, and more. To end the book off, we’ll show you how to update your game with different features, then port the update to the App Store.

Chapter 4. Let's Keep Going! Adding More Functionality

We got a lot accomplished in the last chapter! We figured out level creation, importing our levels into Xcode and getting them and our player all showing up in our game. Are you well rested and ready to tackle even more programming awesomeness? Let's see what we will do in this chapter:

  • Adding awesome sound effects

  • Character animations

  • Playing with particles

  • Menus

  • Adding some enemies

Our game looks pretty awesome, but there's still tons of work to be completed before we can even remotely consider releasing it!

Let's get into it, shall we?

First things first, we ended the last chapter we had just discussed winning the level, and dying during the level, however if you tested it and you died or beat the level and clicked on the replay button, did the game crash? That's because we need to add one final method:

- (void)replay:(id)sender
{
    [[self.view viewWithTag:321] removeFromSuperview];
    [self.view presentScene:[[GameLevelScene alloc] initWithSize...
