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.

In this chapter, we started off on the path of creating a challenging but balanced game experience by enhancing the capabilities of our AI-driven enemies. We gave our enemies zombie-like behavior by allowing them to wander aimlessly around the Level until noticing the player by sight or sound. We also gave them the ability to charge forward when they noticed the player and launch a melee attack, lowering the player's health. Then, we gave the player the chance to fight back by attacking the enemy, eventually destroying them once the enemy's health is depleted. Finally, we gave new flexibility to our game by setting up a system to create new enemies as the game is being played.

At this point, the core content of our game is nearly complete. You should feel proud of the significant progress you have made! You can take some time to tweak the many variables you have...
