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.

Creating Constraints and Gameplay Objectives

In this chapter, we'll define a rule set for our game, which will guide the player through the gameplay experience. We want to give the player the ability to start the game and immediately identify what they have to do in order to win the game. In its most basic form, a game could be defined by the win condition and the steps the player can take to reach that win condition. Ideally, we want to ensure that each step the player takes toward that goal is fun.

We'll begin by applying some constraints to the player in order to increase the level of difficulty. A game without a challenge quickly becomes boring, and we want to ensure that every mechanic in our game provides the player with an interesting choice or challenge. We'll then set up a goal for the player to achieve, along with the necessary adjustments to our enemy...
