Unreal Engine 5 Game Development with C++ Scripting

By: ZHENYU GEORGE LI

Overview of this book

Unreal Engine is one of the most popular and accessible game engines in the industry, creating multiple job opportunities. Owing to C++ scripting's high performance, advanced algorithms, and engineering maintenance, it has become the industry standard for developing commercial games. However, C++ scripting can be overwhelming for anyone without a programming background. Unreal Engine 5 Game Development with C++ Scripting will help you master C++ and get a head start on your game development journey. You’ll start by creating an Unreal Engine C++ project from the shooter template and then move on to building the C++ project and the C++ code inside the Visual Studio editor. You’ll be introduced to the fundamental C++ syntax and essential object-oriented programming concepts. For a holistic understanding of game development, you’ll also uncover various aspects of the game, including character creation, player input and character control, gameplay, collision detection, UI, networking, and packaging a completed multiplayer game. By the end of this book, you’ll be well-equipped to create professional, high-quality games using Unreal Engine 5 with C++, and will have built a solid foundation for more advanced C++ programming and game development technologies.

Understanding collision detection

Game collision detection is a system to detect when two or more game objects overlap or interact with each other in a game world. The process of collision detection is based on mathematical calculations that check whether two shapes intersect with each other (overlap detection) or whether a line goes through a surface (ray casting detection).

To detect actor collisions, Unreal offers certain types of simple collision components that use simple shapes to deal with collision detections:

  • UCapsuleComponent
  • UBoxComponent
  • USphereComponent

Besides using the collision components, another option to add simple collision shapes to static meshes is to add them via the Mesh Editor. Double-click on any mesh (model) on the Content Drawer to open the Mesh Editor. You should find the Collision menu item in the Blueprint Editor menu or on the toolbar:
