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.

Creating an elevator

Continuing with what you learned from the previous section, we can take animations to another level by making moving platforms. However, UFPS comes with its own built-in way of doing this.

From the Project tab, open the Chapter 6_3_ElevatorStart level. This will give us a simple starting point to create an elevator.
Alternatively, use a level that we created previously and add an elevator to it.
From Prototype, create a cube by pressing Ctrl + K. Move it to ground level in a 3 x 3 x 1 size cube.
Go to the Object editing mode and set Vertex Color to Grab to make it easy for us to see.
Rename the object to Platform01. Finally, from the Prototype tab, click on the Set Mover button to make the object a mover.
Create a new game object by going to GameObject | Create Empty. Name this new object Platform01Path.
Create a duplicate of our Platform01 object by selecting it from the Hierarchy tab and pressing Ctrl + D. Rename this object to 01 and make it a child of Platform01Path.
