Overview of this book

Game engines are central to the video games we know and love. From the artwork to the mathematics that underpin the frames onscreen, the engine calls the shots. Aside from offering one of the leading 3D game engines, Unity also provides a superlative development tool ñ a tool that can produce professional standard games for Mac, PC, and the Unity Web Player. This book is a complete exercise in game development covering environments, physics, sound, particles, and much more, to get you up and working with Unity quickly. Taking a practical approach, this book will introduce you to the concepts of developing 3D games before getting to grips with development in Unity itself. From creating 3D worlds to scripting and creating simple game elements you will learn everything you'll need to get started with game development for the PC, Mac, and Web. This book is designed to cover a set of easy to follow examples, which culminate in the production of a First Person 3D game, complete with an interactive island environment. By introducing common concepts of game and 3D production, you'll explore Unity to make a character interact with the game world, and build puzzles for the player to solve, in order to complete the game. At the end of the book, you will have a fully working 3D game and all the skills required to extend the game further, giving your end-user, the player, the best experience possible. Soon you will be creating your own 3D games with ease!

Let's begin by looking at the objects that make up our First Person Controller (FPC) before we look into the components that make it work.

Click on the gray arrow to the left of First Person Controller in the Hierarchy in order to reveal the objects nested underneath. When objects are nested in this way, we say that there is a parent-child relationship. In this example, First Person Controller is the parent, while Graphics and Main Camera are its child objects. In the Hierarchy, child objects are indented to show their parenting, as shown in the following screenshot:

Parent-child issues

When considering nested or child objects, you should note that there are some key rules to remember.

A child object's position and rotation values are relative to their parent. This is referred to as the local position and local rotation. For example, you may consider your parent object to exist at (500, 35, 500) in world coordinates, but when selecting a child...
