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.

Integrating an AI system – Shooter AI

As mentioned in the previous section, there is another tool called Shooter AI, which is currently available at the Asset Store. However, unlike the base RAIN program, it is not free and will require a purchase. However, it is the simpler of the two to set up and also uses Unity's own NavMesh system instead of RAIN's proprietary version. Keeping this in mind, let's create a ranged enemy to shoot at us.

Note

As of this writing, there is talk of AI Shooter being replaced by another AI System called Paragon Shooter AI.

Most of the content regarding the AI system should work similarly to what's described here. For more information on that check out: http://forum.unity3d.com/threads/paragon-ai-first-third-person-shooter-ai.305971/.

To download Shooter AI, we'll use the Asset Store again. In order to do this, navigate to Window | Asset Store.
In the top-right corner, you'll see a search bar. Type in Shooter AI and press Enter. Once you do this, the first asset you...
