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.

Setting a gameplay win condition

We will modify our HUD Blueprint and player character Blueprint to account for a target goal that the player must strive to achieve. We will display the target goal in the HUD next to the target count, so the player can easily see how many targets need to be destroyed to reach their goal.

We will also create another Widget Blueprint representing a win menu screen that will be shown to the player when they reach their goal. Finally, we will implement the logic needed to check whether the player has won and to show the win menu screen.

Displaying a target goal in the HUD

First, we need to create a variable in the FirstPersonCharacter Blueprint that will establish how many targets we are asking the player to destroy to win the game. Then, we need to display this information to the player in the HUD Blueprint.

Follow these steps to display the target goal:
