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.

Installing Prototype

In general, creating levels in Unity is a painful experience. You have to type in the values for each piece that you want to add or you have to create everything inside a modeling program and import it, which will require you to have 3D modeling skills.

Other game engines have tools like Binary Space Partitioning (BSP) or Constructive Solid Geometry (CSG), which allow you to build geometry from scratch and apply materials to it to create areas for play. Filling in the gap that Unity has, ProCore3D has created a toolkit that allows for in-editor construction.

We will later on use ProBuilder to polish up our final product; but, in the meantime, we will use Prototype, their free version to build the basic structure and flow of our levels without wasting time, thus making things visually appealing until we polish it. Perform the following steps to install Prototype:

  1. Open the Asset Store once again by going to the toolbar, searching for Prototype, and looking for the following icon:
    Installing Prototype
  2. Click on the first option in the top-left corner and you should be brought to a page like the following one:
    Installing Prototype

    Tip

    After the writing of this book, Prototype will in the near future be replaced by ProBuilder Basic which is still 100% free but has additional features. I've talked with the creators about this, and they've confirmed with me after reading the book that everything discussed here should still work with the new version. For more information on this, check out http://www.protoolsforunity3d.com/probuilder/.

  3. Click on the Download button and wait for it to finish. Then, import the entire package by clicking on Import.
  4. We will now test it out to see whether everything is imported correctly. Create a new scene inside Unity by going to File | New Scene. Once there, press Ctrl + K to create a new cube using Prototype.
    Installing Prototype

With this, we know that it was installed correctly! It may look pretty simple now, but we will be diving even more into using these tools later on.
