Unreal Engine 4 Game Development Quick Start Guide

By: Rachel Cordone

Overview of this book

Unreal Engine is a popular game engine used by developers for building high-end 2D and 3D games. This book is a practical guide designed to help you get started with Unreal Engine 4 and confidently develop interactive games. You’ll begin with a quick introduction to the Unreal Engine 4 (UE4) ecosystem. Next, you’ll learn how to create Blueprints and C++ code to define your game's functionality. As you progress, you’ll cover the core systems of UE4 such as Unreal Motion Graphics (UMG), Animation Blueprints, and behaviour trees to further build on your game development knowledge. The concluding chapters will then help you learn how to use replication to create multiplayer games. By the end of this book, you will be well-versed with UE4 and have developed the skills you need to use the framework for developing and deploying robust and intuitive games.

In this chapter, we've learned how to create some simple AI by making our own Pawn and Controller with some code to make them run around a Nav Mesh. Then, we expanded on this by creating our own Behavior Tree with tasks, decorators, and services to expand on our AI's behavior.

You can see how Behavior Trees make creating complex AI a lot simpler. If we tried to do even this simple one in code, it would quickly become a complicated mess. It would be difficult to make major modifications, and it would be difficult to debug.

Even the code we made that detects the player can be simplified and made a lot more flexible. For more advanced reading, look into adding an AI perception component to the enemy's controller class:

In the next chapter, we'll take a look at creating multiplayer games, and the...
