Blueprints Visual Scripting for Unreal Engine - Second Edition

By: Marcos Romero, Brenden Sewell

Overview of this book

Blueprints is the visual scripting system in Unreal Engine that enables programmers to create baseline systems and can be extended by designers. This book helps you explore all the features of the Blueprint Editor and guides you through using Variables, Macros, and Functions. You’ll also learn about object-oriented programming (OOP) and discover the Gameplay Framework. In addition to this, you’ll learn how Blueprint Communication allows one Blueprint to access information from another Blueprint. Later chapters will focus on building a fully functional game using a step-by-step approach. You’ll start with a basic first-person shooter (FPS) template, and each chapter will build on the prototype to create an increasingly complex and robust game experience. You’ll then progress from creating basic shooting mechanics to more complex systems, such as user interface elements and intelligent enemy behavior. The skills you will develop using Blueprints can also be employed in other gaming genres. In the concluding chapters, the book demonstrates how to use arrays, maps, enums, and vector operations. Finally, you’ll learn how to build a basic VR game. By the end of this book, you’ll have learned how to build a fully functional game and will have the skills required to develop an entertaining experience for your audience.

Data Structures and Flow Control

In section 3, we learned how to create a basic AI game using Behavior Trees, how to add game states, and how to build and publish a game.

Section 4 will teach you about advanced Blueprints concepts that will help when developing complex games. We will learn about data structures, flow control, math nodes, Blueprints tips, and gain an understanding of virtual reality development.

This chapter will explain what data structures are and how they can be used to organize data in Blueprints. We will learn about the concept of containers and how to use arrays, sets, and maps to group multiple elements, as well as other ways to organize data using enumerations, structures, and data tables. In this chapter, we will also see how to control a Blueprint's flow of execution by using various types of flow control nodes.
