Preface

Game engines, such as Unreal Engine 4—as the tools that power the creation of the commercial games we love to play—are becoming increasingly accessible to both experienced and novice game developers outside of the traditional studio environment. Previous versions of Unreal Engine have powered many of the most popular console and PC games released over the last decade, and the newest version contains the tools for funneling this power into the hands of as many aspiring developers as possible. The most transformative of these tools is the Blueprints Visual Scripting system, which allows people who are not full-time programmers to create and implement the mechanics, interfaces, and interactions of a game.

Taking a step-by-step approach, this book will guide you through the process of using the visual nodes that make up Blueprint behavior, and link them together to create game mechanics, user interfaces, and more. In this process, you will be learning all the skills you need to get started with developing games in Unreal Engine 4 using Blueprints.

Starting with a basic first-person shooter template, each chapter will extend the prototype to create an increasingly complex and robust game experience. You will progress from creating basic shooting mechanics to gradually more complex systems that will generate user interface elements and intelligent enemy behavior. By focusing on universally applicable skills, the expertise you will develop in utilizing Blueprints can translate to other types of genres. By the time you finish this book, you will have a fully functional first-person shooter and the skills necessary to expand on the game to develop an entertaining, memorable experience for your players.
