Learning Unreal Engine Game Development

By: Joanna Lee

Overview of this book

Unreal Engine 4 is a powerful game development engine that provides rich functionalities to create 2D and 3D games across multiple platforms. Many people know what a game is and they play games every day, but how many of them know how to create a game? Unreal Engine technology powers hundreds of games, and thousands of individuals have built careers and companies around skills developed using this engine. Learning Unreal Engine 4 Game Development starts with small, simple game ideas and playable projects that you can actually finish. The book first teaches you the basics of using Unreal Engine to create a simple game level. Then, you'll learn how to add details such as actors, animation, effects, and so on to the game. The complexity will increase over the chapters and the examples chosen will help you learn a wide variety of game development techniques. This book aims to equip you with the confidence and skills to design and build your own games using Unreal Engine 4. By the end of this book, you'll have learnt about the entire Unreal suite and know how to successfully create fun, simple games.

BSP Brush


We used the BSP Box Brush in Chapter 2, Creating Your First Level, extensively to create the ground and the walls.

BSP Brushes are the primary building blocks for level creation in the game development. They are used for quick prototyping levels like how we have used them in Chapter 2, Creating Your First Level.

In Unreal, BSP Brushes come in the form of primitives (box, sphere, and so on) and also predefined/custom shapes.

Background

BSP stands for binary space partitioning. The structure of a BSP tree allows spatial information to be accessed quickly for rendering, especially in 3D scenes made up of polygons. A scene is recursively divided into two, until each node of the BSP tree contains only polygons that can render in arbitrary order. A scene is rendered by traversing down the BSP tree from a given node (viewpoint).

Since a scene is divided using the BSP principle, placing objects in the level could be viewed as cutting into the BSP partitions in the scene. Geometry Brushes use...
