Mastering Unreal Engine 5 Game Development with C++ Scripting: Build efficient, scalable gameplay systems using advanced C++ in UE5

Advanced C++ for Serious Unreal Engine 5 Developers

Mastering Unreal Engine 5 Game Development with C++ Scripting is written for programmers who already know the basics and want to work closer to the engine’s architecture. Marco Secchi, a freelance game programmer and lecturer, guides readers through the systems that make UE5 projects scalable, maintainable, and performant.

Instead of treating C++ as an afterthought to Blueprints, the book puts code at the centre of production. It examines how Unreal builds projects, how reflection powers gameplay classes, and how modern pointer types help manage memory safely.

Inside the Engine Pipeline

The opening chapters look at the tools that turn source code into a running game. You’ll explore the Unreal Build Tool, Unreal Header Tool, and Unreal Automation Tool, with attention to target files, build files, Clang, and common pitfalls. This foundation matters because build and reflection systems shape nearly everything a gameplay programmer writes.

Reflection, Macros, and Practical C++

From there, the book moves into the Unreal reflection system. It explains header formats, class and struct declarations, interfaces, and the macros that connect C++ code to the editor. Readers work with UCLASS, UFUNCTION, and UPROPERTY specifiers, including metadata usage, through examples that build on a companion project called Paws in the Shell.

A dedicated chapter on pointers covers TObjectPtr, TWeakObjectPtr, TStrongObjectPtr, TSoftObjectPtr, and Unreal’s smart-pointer library. It also discusses when raw pointers are still appropriate and how object pooling can improve performance.

Who This Book Is For

This is a focused resource for C++ programmers, gameplay engineers, and technical developers who want to move beyond introductory Unreal Engine material. It assumes prior programming knowledge and a working understanding of the engine, then builds toward advanced concepts used in complex projects.

If you are ready to read engine source with more confidence and structure your UE5 code for real production work, this book offers a clear, practical path.
