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.

The Motion Controller Blueprint

Motion Controllers are implemented by the BP_MotionController Blueprint. Double-click it to open the Blueprint Editor.

Click on the Viewport tab to see a visual representation of the Blueprint, as shown in the following screenshot. The Motion Controller is represented by a hand Skeletal Mesh and has other visual Components that are used in the teleport:

The next screenshot shows the Components panel of BP_MotionController:

Brief descriptions of the Components are as follows:

  • Scene: The root Component.
  • MotionController: The Motion Controller Component that tracks a Motion Controller device. When you move the Motion Controller device, the data of this movement is sent to the Motion Controller Component.
  • HandMesh: A Skeletal Mesh Component of a hand.
  • ArcDirection: An arrow Component used to indicate the direction of the teleport.
  • ArcSpline: A Spline...
