Overview of this book

Unity is one of the biggest game engines in the world, providing the user with a range of important tools that they need to bring their ideas into reality. Beginner game developers are optimistic, passionate, and ambitious, but that ambition can be dangerous! Too often, budding indie developers and hobbyists bite off more than they can chew. Games like Angry Birds, Cut the Rope, and Fruit Ninja are fun, simple games that have delighted players and delivered big profits to their creators. This is the perfect climate for new game developers to succeed by creating simple games with Unity, starting today. This book teaches you the ins and outs of the unique Unity game engine interface. Clear and concise code examples written in both Unity Javascript and C# take you through the step-by-step process of building five small, functional games. With this understanding you can start making your own mark on the game industry! With absolutely no programming or game development experience, you will learn how to build five simple games in Unity by following step-by-step instructions, peppered with amusing analogies and anecdotes from an experienced indie developer. Following a primer on simplifying your game ideas to that single “something” that keeps players coming back for more, dive into the Unity game engine by creating a simple bat-and-ball game. From there, you'll build a complete memory game using only the Unity GUI system. After building a 2.5D mouse avoider game, you'll learn how to re-skin the project to completely change the game's theme. Incorporating everything you've learned, you'll return to complete the bat-and-ball game by adding scoring, replay flow, sound effects, and animations. Finally, in the new bonus chapter, you'll program some simple AI (Artificial Intelligence) for a tic tac toe game. "Unity 4.x Game Development by Example" is a fun and light-hearted exploration of one of the most powerful game engines on the market today. Find out what all the fuss is about by getting up to speed using this book!

Time for action – nix the mip-mapping


There's an unwanted sparkly effect that can occur when a 3D camera gets closer and farther away from a 2D image. A technique called mip-mapping reduces this effect. Unity creates a series of images from your texture that are each half the size of the previous image, which allows the computer to figure out the best pixel colors to show to the player, reducing the sparkle effect.

Because our title screen is presented as-is with no 3D camera movement, we're not really concerned about sparkle. And, as you can imagine, with all those extra images, mip-mapping requires a decent amount of extra memory for storage. As we don't need mip-mapping—adding that extra bulk—let's disable it:

  1. With the "title" texture image selected, find the Generate Mip Maps checkbox in the Inspector panel.

  2. Uncheck the box.

  3. Click on Apply to save these changes.

  4. The rest of the images that you imported should not be mip-mapped, but there's no harm in checking them for peace of mind.
