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.

Setting up a testbed

Now, before we get started, let's create an area that we can use to test our new weapons.

Open up the project and a scene for us to work with. We can create a new level but, in this instance, UFPS comes with a nice scene for us to start with. From the Project tab, go to the UFPS/Base/Content/Levels/CleanScene folder and double-click on the CleanScene file.
This scene (or level) is a simple terrain with a basic first-person camera and controller intended for prototyping, which is perfect for us, except we want our player to be already set up. To do this, we will remove this simple camera and replace it with a built-in one.
From the Hierarchy tab, select the Camera object by clicking on it and delete it by pressing the Delete key.
Next, go to the UFPS/Base/Content/Prefabs/Players folder and drag and drop an AdvancedPlayer prefab into your game world. To see the object, double-click on it in Hierarchy (or press the F hotkey with it selected) and it'll zoom directly...
