Overview of this book

Unreal Engine is a powerful game development engine that provides rich functionalities to create 2D and 3D games. Developers have the opportunity to build cross-platform mobile and desktop games from scratch. This book will show you how to apply artificial intelligence (AI) techniques to your Unreal project using blueprints as your scripting language. You will start with an introduction to AI, and learn how it is applied to gaming. Then you'll jump right in and create a simple AI bot and apply basic behaviors to allow it to move randomly. As you progress, you'll find out how to implement randomness and probability traits. Using NavMesh, you will impart navigation components such as character movement, MoveTo nodes, settings, and world objects, and implement Behavior Trees. At the end of the book, you will troubleshoot any issues that might crop up while building the game.

Chapter 2. Creating Basic AI

In this chapter, we will create our first AI step-by-step and talk about the techniques that we demonstrate along the way. So today, we will dive right into Unreal Engine 4 using the bare components needed to create a single state with random movement for your AI. We will then review what we've done, the changes we can make, and the disadvantages of the techniques demonstrated.

This chapter will cover:

  • Setting up our project
  • Creating the AIController
  • Sending instructions to Pawn with the AIController
  • Creating small blueprint scripts to assist in navigation
