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.

Adding movement

Now that we have a target that responds to the player shooting, we can add some sort of challenge to start making our project feel like a game. A simple way to do this is to add some movement to our target. To accomplish this, we first must declare that our target Actor is an object that is intended to move, and then we need to set up logic within the Blueprint that manages how it moves. Our goal is to make the target Cylinder move back and forth across our Level.

Changing the Actor's Mobility and Collision settings

To allow our target to move, we first must change its Mobility setting to Moveable. This allows an Actor to be manipulated while playing the game. To do this, follow these steps:

Important Information

By default, basic Actors that are placed in the world are set to Static. Static means that an object cannot move or be manipulated during gameplay. Static objects are significantly less resource-intensive to render, and this should be our default...
