Modern Game Development in Unreal Engine 5 with C++

Modern Game Development in Unreal Engine 5 with C++ is a systems-focused guide to professional Unreal Engine development. Written for developers who want to move beyond prototypes and tutorial code, this book teaches how real-time gameplay systems are architected, implemented, optimized, and shipped in modern UE5 projects.

Rather than teaching Unreal feature-by-feature in isolation, the book approaches the engine as a connected ecosystem — showing how gameplay architecture, networking, animation, AI, input, and optimization work together inside production codebases.

This is not a beginner introduction to programming. It is a practical engineering guide for developers who want a deeper command of Unreal Engine 5 and modern C++ game development.

Inside this book, you’ll learn how to:

• Understand UE5’s architecture, module system, reflection system, and UObject model
• Build scalable gameplay frameworks using GameMode, GameState, PlayerController, Pawn, and Subsystems
• Design maintainable gameplay systems with modern C++ and Unreal Engine patterns
• Implement advanced character movement and custom movement modes
• Build production-ready systems using the Gameplay Ability System (GAS)
• Create AI architecture with Behavior Trees, Blackboards, EQS, perception systems, and navigation
• Develop animation pipelines using state machines, montages, Control Rig, layered animation, and motion warping
• Build multiplayer gameplay systems with replication, RPCs, prediction, lag compensation, and server authority
• Profile and optimize CPU, GPU, memory, ticking, rendering, and network performance
• Structure Unreal projects for production, testing, tooling, packaging, deployment, and long-term maintainability

Along the way, you’ll build/create:

• A scalable UE5 gameplay architecture designed for real production workflows
• Multiplayer-ready gameplay systems with replication and prediction support
• GAS-driven ability, attribute, and combat systems
• AI systems that scale from individual enemies to coordinated groups and crowds
• Animation systems integrated cleanly with gameplay and networking
• Replicated inventory, movement, and combat frameworks
• Professional optimization and profiling workflows using Unreal Insights
• Production-oriented tooling and packaging pipelines for shipping Unreal Engine games

This book is written for experienced programmers entering Unreal Engine, Blueprint developers transitioning to C++, and Unreal C++ developers who want a more structured understanding of large-scale gameplay architecture.

What sets this book apart is its focus on systems thinking, production realities, and long-term scalability. Instead of relying on simplified demo projects or disconnected examples, it teaches the architectural patterns used in professional Unreal Engine development which are the patterns required to build performant, maintainable, multiplayer-ready games in Unreal Engine 5.
