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.

Summary

This chapter presented some math concepts and showed you how to use world and relative transforms. We saw how several Blueprint nodes are used to modify an element of a transform, such as Location, Rotation, and Scale.

This chapter has shown that a vector structure can be used to represent a point in 3D space or a mathematical vector. We learned how to do several vector operations using Blueprint nodes.

Finally, we saw how to test collisions using the trace nodes. There are many trace nodes, which are based on the type of collision response, the shapes used, and whether the trace nodes return single or multiple hits.

In the next chapter, we will learn several tips for dealing with the complexity of Blueprints and increasing the quality of Blueprints.
