Unreal Engine 4 AI Programming Essentials

By: Jie Feng, Peter Newton

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.

Overview


AI Perception is a system within Unreal Engine 4 that allows sources to register their senses to create stimuli, and then the other listeners are periodically updated as the sense stimuli is created within the system. This works wonders for creating a reusable system that can react to an array of customizable sensors. So, this chapter will focus on using the AI Perception component to have our enemy AI chase us whenever we are detected. What we will do differently is that this will all be scripted using Blueprint. So, there is no need to use Behavior Tree this time around!
