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!

As we already have a working menu, rather than removing it from our scene, we will temporarily disable the objects that make it up. By doing this, you can choose which menu you prefer later and reinstate as necessary.

Disabling Game Objects

One at a time, select the PlayBtn, the InstructionsBtn, and the QuitBtn in the Hierarchy, and deactivate them by doing the following:

  • In the Inspector, deselect the checkbox to the left of the name of the object

  • Ensure that this has turned the text of the object to light gray in the Hierarchy and that the element itself has disappeared from the Game view preview

Writing an OnGUI() script for a simple menu

Now, create a new empty object by going to GameObject | Create Empty. This makes a new object in the Hierarchy called GameObject with only a Transform component attached. This will be the holder object for our GUI 2.0 menu. This is because the script we are going to write will need to be attached as a component in...
