Overview of this book

Unity, available in free and pro versions, is one of the most popular third-party game engines available. It is a cross-platform game engine, making it easy to write your game once and then port it to PC, consoles, and even the web, making it a great choice for both indie and AAA developers. Building an FPS Game in Unity takes readers on an exploration of how to use Unity to create a 3D first person shooter (FPS) title, leveraging the powerful UFPS framework by VisionPunk and Prototype/ProBuilder 2.0 by ProCore3D. After some setting up, you will start by learning how to create custom weapons, prototype levels, create exterior and interior environments, and breathe life into our levels. We will then add polish to the levels. Finally, we will create a custom GUI and menus for our title to create a complete package.

Project creation

At this point, I assume that you have freshly installed Unity and have started it up. Follow these steps to create a new project in Unity:

With Unity started, go to New Project. Enter a Project Name value such as FPS Game - Chapter 1 as that's what we are making and the chapter we're making it for, or whatever you want to call your project. Select Location of your choice somewhere on your hard drive and ensure that you have your game set to 3D. Once completed, select Create project. At this point, we do not need to import any packages as we'll be doing it manually.
Here on, if you see the Welcome to Unity pop up, feel free to close it as we won't be using it. At this point, you will be brought to the general Unity layout, which should look as follows:

Note

I'm assuming you have some familiarity with Unity before you read this book. If you want more information on the interface, please visit http://docs.unity3d.com/Documentation/Manual/LearningtheInterface.html.
