1. Laying Out a Game

Laying Out Your Engine Creating an Inheritance-Based Game Layout Creating a Component-Based Game Layout Calculating Delta Times Detecting When the User Enters and Exits Your Game Updating Based on a Timer Updating Based on When the Screen Updates Pausing a Game Calculating Time Elapsed Since the Game Start Working with Blocks Writing a Method That Calls a Block Working with Operation Queues Performing a Task in the Future Storing Blocks in Objects Using a Timer Making Operations Depend on Each Other Filtering an Array with Blocks Loading New Assets During Gameplay Adding Unit Tests to Your Game 2D Grids

2. Views and Menus

Working with Storyboards Creating View Controllers Using Segues to Move Between Screens Using Constraints to Lay Out Views Adding Images to Your Project Slicing Images for Use in Buttons Using UI Dynamics to Make Animated Views Moving an Image with Core Animation Rotating an Image Animating a Popping Effect on a View Theming UI Elements with UIAppearance Rotating a UIView in 3D Overlaying Menus on Top of Game Content Designing Effective Game Menus

3. Input

Detecting When a View Is Touched Responding to Tap Gestures Dragging an Image Around the Screen Detecting Rotation Gestures Detecting Pinching Gestures Creating Custom Gestures Receiving Touches in Custom Areas of a View Detecting Shakes Detecting Device Tilt Getting the Compass Heading Accessing the User’s Location Calculating the User’s Speed Pinpointing the User’s Proximity to Landmarks Receiving Notifications When the User Changes Location Looking Up GPS Coordinates for a Street Address Looking Up Street Addresses from the User’s Location Using the Device as a Steering Wheel Detecting Magnets Utilizing Inputs to Improve Game Design

4. Sound

Playing Sound with AVAudioPlayer Recording Sound with AVAudioRecorder Working with Multiple Audio Players Cross-Fading Between Tracks Synthesizing Speech Getting Information About What the iPod Is Playing Detecting When the Currently Playing Track Changes Controlling iPod Playback Allowing the User to Select Music Cooperating with Other Applications’ Audio Determining How to Best Use Sound in Your Game Design

5. Data Storage

Saving the State of Your Game Storing High Scores Locally Using iCloud to Save Games Using the iCloud Key/Value Store Loading Structured Information Deciding When to Use Files or a Database Using SQLite for Storage Managing a Collection of Assets Storing Information in NSUserDefaults Implementing the Best Data Storage Strategy In-Game Currency

6. 2D Graphics and Sprite Kit

Getting Familiar with 2D Math Creating a Sprite Kit View Creating a Scene Adding a Sprite Adding a Text Sprite Determining Available Fonts Including Custom Fonts Transitioning Between Scenes Moving Sprites and Labels Around Adding a Texture Sprite Creating Texture Atlases Using Shape Nodes Using Blending Modes Using Image Effects to Change the Way that Sprites Are Drawn Using Bézier Paths Creating Smoke, Fire, and Other Particle Effects Shaking the Screen Animating a Sprite Parallax Scrolling Creating Images Using Perlin Noise

7. Physics

Reviewing Physics Terms and Definitions Adding Physics to Sprites Creating Static and Dynamic Objects Defining Collider Shapes Setting Velocities Working with Mass, Size, and Density Creating Walls in Your Scene Controlling Gravity Keeping Objects from Falling Over Controlling Time in Your Physics Simulation Detecting Collisions Finding Objects Working with Joints Working with Forces Adding Thrusters to Objects Creating Explosions Using Device Orientation to Control Gravity Dragging Objects Around Creating a Car

8. 3D Graphics

Working with 3D Math Creating a GLKit Context Drawing a Square Using OpenGL Loading a Texture Drawing a Cube Rotating a Cube Moving the Camera in 3D Space

9. Intermediate 3D Graphics

Loading a Mesh Parenting Objects Animating a Mesh Batching Draw Calls Creating a Movable Camera Object

10. Advanced 3D Graphics

Understanding Shaders Working with Materials Texturing with Shaders Lighting a Scene Using Normal Mapping Making Objects Transparent Adding Specular Highlights Adding Toon Shading

11. Artificial Intelligence and Behavior

Making an Object Move Toward a Position Making Things Follow a Path Making an Object Intercept a Moving Target Making an Object Flee When It’s in Trouble Making an Object Decide on a Target Making an Object Steer Toward a Point Making an Object Know Where to Take Cover Calculating a Path for an Object to Take Finding the Next Best Move for a Puzzle Game Determining if an Object Can See Another Object Using AI to Enhance Your Game Design

12. Networking and Social Media

13. Game Controllers and External Screens

Detecting Controllers Getting Input from a Game Controller Showing Content via AirPlay Using External Screens Designing Effective Graphics for Different Screens Dragging and Dropping

14. Performance and Debugging

Improving Your Frame Rate Making Levels Load Quickly Dealing with Low-Memory Issues Tracking Down a Crash Working with Compressed Textures Working with Watchpoints Logging Effectively Creating Breakpoints That Use Speech
