Author's Note

Unreal Engine's Blueprint visual scripting system not only allows designers to script their games, but also allows programmers to create primitives that designers can extend.

Unreal Engine's Blueprint visual scripting system allows designers, as well as programmers, to script games by providing a foundational element that designers can extend.
This book explores all the features of the Blueprint Editor, along with expert tips, shortcuts, and best practices.
It also guides you through using variables, macros, and functions, and helps you learn about Object-Oriented Programming (OOP).
Learn about the gameplay framework and how Blueprint communication allows you to access information from other Blueprints.
In subsequent chapters, we will focus on building a fully functional game step by step.
Starting with a basic first-person shooter (FPS) template, each chapter builds on the prototype to create increasingly complex and robust game experiences.
We then progress from building basic mecha shooters to more complex systems like user interface elements and intelligent enemy behavior.

This book introduces how to use arrays, maps, enumerations, and vector operations, and introduces the elements necessary for VR game development.
The first chapter explains how to implement procedure creation and how to write a product configurator.
By the end of this book, you'll have the skills you need to create fully functional games and develop engaging experiences for your players.

Translator's Note

The present age is an age where content is created by utilizing existing tools rather than by creating authoring tools.
We live in an era where it's crucial to produce higher quality, faster results.
In the gaming industry, it has become important not to create a game engine, but to quickly create high-quality games that satisfy users' needs using a game engine.
Epic Games' Unreal Engine is the most feature-rich and powerful engine for creating high-quality games.
Getting the most out of this powerful Unreal Engine is no easy task.
Because there is a huge barrier called programming.
As a solution to this barrier, Epic Games offers Blueprint visual scripting.
Even if you're not a programmer, you can quickly and easily create the results you want by visually implementing actions.
Finally, I hope this book will be helpful to those studying Unreal Engine 5.
