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.
