Overview of this book

Unreal Engine's Blueprint visual scripting system enables designers to script their games and programmers to create base elements that can be extended by designers. With this book, you'll explore all the features of the Blueprint Editor, along with expert tips, shortcuts, and best practices. The book guides you through using variables, macros, and functions, and helps you learn about object-oriented programming (OOP). You'll discover the Gameplay Framework and advance to learning how Blueprint Communication allows one Blueprint to access information from another Blueprint. Later chapters focus on building a fully functional game step by step. 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 book demonstrates how to use arrays, maps, enums, and vector operations and introduces the elements needed for VR game development. In the final chapters, you’ll learn how to implement procedural generation and create a product configurator. By the end of this book, you'll have learned how to build a fully functional game and have the skills required to develop an entertaining experience for your audience.

Teleportation

In this section, we'll see the event and functions used in teleportation.

To start the teleport, press up on the right motion controller's thumbstick to mark a location. When you release the thumbstick, you will teleport to the marked location. The teleport destination is represented by the VRTeleportVisualizer Blueprint:

The input event used for teleportation is InputAxis MovementAxisRight_Y. The first nodes of the event check whether Axis Value is positive, which means the thumbstick was pressed up, and check whether Axis Value is greater than the deadzone, which is a minimum Axis Value to start the teleport:

The next screenshot shows the nodes connected to the True output of the Branch node of Figure 16.8. The Do Once node is used to ensure that the Start Teleport Trace function...
