Unreal Engine 4 AI Programming Essentials

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 8. Creating Patrol, Chase, and Attack AI

In this chapter, we will combine some of the components we used in the previous chapters, including AI Sense and other components, to have AI navigate. Then, we will add some randomness in the time-out time that will make the AI chase after the characters it detects. Now, in this chapter, we can create AI using Behavior Tree while utilizing other AI components. A combination of these components can create responsive and convincing AI behavior.

The goal of this chapter is to create an AI that will fire at you using Behavior Tree; this last AI component will benefit you because there is no perfect solution. So, understanding each of the available tools allows you to exploit the advantages of each component for your use in AI. These tools allow you to create AI that is responsive and convincing.
