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.

Increasing the projectile's speed

Now that we have given the player character a new gameplay option to navigate the world, our focus will be back on the shooting mechanics. Right now, the shots fired from the gun on the controller are spheres that slowly arc through the air. We want to better approximate the fast-moving bullets that we are used to from traditional shooters.

To change the properties of Projectile, we need to open the Blueprint called FirstPersonProjectile, which is in the Content|FirstPersonBP| Blueprints folder. Once opened, look at the Components panel and click on Projectile. This is a projectile movement Component that has been added in the FirstPersonProjectile Blueprint to define how the sphere will travel once it is created in the world:

  1. In the Details panel, you will see that Projectile has a lot of variables that describe its movement. We are interested in only a few of these at this time:
