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.

Constraining player Actions

One important consideration to make when adding enhanced capabilities to the player is the impact that the ability has on both the challenge and feel of the game experience. Recall that we added the ability for the player to sprint in Chapter 6, Enhancing Player Abilities, by holding down the Shift key. As it currently stands, holding down the Shift key while moving provides a significant increase in the speed at which the player can move. Without constraints applied to this ability, such as an enforced waiting period between uses, there would be nothing discouraging the player from holding down the Shift key at all times as they move.

This goes against the goal we set out to accomplish by adding a sprint functionality, which was to provide more options to the player. If an option is so attractive that the player feels compelled to utilize it at all...
