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 – making the mesh colliders convex


Provided our mesh is made from fewer than 255 triangles, one thing that we can do to make our Mesh Colliders behave better is to mark them as "convex". (You can see how many triangles comprise a mesh by clicking the mesh and looking at the Preview section of the "Inspector" panel.) GameObjects that are in motion (like our HandsAndTray soon will be) tend to react better with other moving colliders if we make this small change.

  1. In the Hierarchy panel, hold down the ALT key on your keyboard and click on the grey arrow next to the HandsAndTray GameObject. Instead of just expanding the top-level item, this expands the entire tree beneath the parent GameObject.

  2. Select Hands_Mesh.

  3. In the Inspector panel, under the Mesh Collider Component, check the box labeled Convex.

  4. Do the same for Tray_Mesh.

  5. As we did with the paddle before it, add a Rigidbody component to the HandsAndTray GameObject, and check the Is Kinematic box in the Inspector panel. As...
