Overview of this book

Unreal Engine is a popular game engine used by developers for building high-end 2D and 3D games. This book is a practical guide designed to help you get started with Unreal Engine 4 and confidently develop interactive games. You’ll begin with a quick introduction to the Unreal Engine 4 (UE4) ecosystem. Next, you’ll learn how to create Blueprints and C++ code to define your game's functionality. As you progress, you’ll cover the core systems of UE4 such as Unreal Motion Graphics (UMG), Animation Blueprints, and behaviour trees to further build on your game development knowledge. The concluding chapters will then help you learn how to use replication to create multiplayer games. By the end of this book, you will be well-versed with UE4 and have developed the skills you need to use the framework for developing and deploying robust and intuitive games.

Widgets can be set to automatically grab data from variables in our widget classes. This is done by binding a property to one of our variables. Let's take a look at how that works:

  1. Open the MyWidget Blueprint

  4. Create a SET node for our new Pickups variable and connect it to the Remaining Pickups Int to Text conversion and the output of the ThirdPersonGameMode cast

The function should now look like the following screenshot:

Now that our variable is updating, we just need to bind the Text widget's property to it:

  1. In the Designer window, select the Text widget.
  2. In the Details panel, there is a Bind drop-down box next to Content | Text. You can select the...
