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.

In this chapter, we began the process of changing our simple, moving targets into fleshed-out game enemies that can challenge the player. In the process, you learned about the fundamentals of how AI Controllers, Behavior Trees, and Blackboards can be leveraged together to create an enemy with the ability to sense the world around them and make decisions based on that information.

As we continue the process of developing our AI to pose a serious challenge to the player, you can use the skills you have learned to consider other kinds of behaviors you might be able to provide to an enemy. Continued exploration of AI mechanics will see you continually coming back to the core loop of sensing, decision-making, and acting that we began implementing here.

In the next chapter, we'll extend our AI behavior to create an enemy that can truly challenge the player. We will add...
