Building RPG Combat in Unreal Engine 5 with C++ and GAS

Creating a responsive and scalable combat system is one of the most challenging parts of RPG development. This text-based guide teaches you how to leverage the industry-standard Gameplay Ability System (GAS) in Unreal Engine 5 using C++ to build robust combat mechanics. Through clear written explanations, code walkthroughs, and step-by-step logic breakdowns, you will transition from understanding basic game loop logic to structuring complex, modular abilities. You will learn how to manage character attributes, handle dynamic damage calculations, and program intelligent enemy behaviors that make combat feel alive. What you'll learn: - Understand the core architecture of the Gameplay Ability System (GAS) including abilities, attributes, and gameplay effects. - Implement a modular melee combo system using C++, Gameplay Tags, and animation synchronization. - Configure character attributes like health and stamina, and design custom calculations for handling damage. - Create intelligent enemy AI using behavior trees, environmental queries, and pathfinding avoidance. - Develop advanced combat mechanics such as directional rolling, parrying, and target-locking systems. - Apply modern C++ practices and the Enhanced Input System for clean, maintainable gameplay code. The course begins with foundational concepts of GAS and C++ integration before guiding you through player abilities, state management, and advanced enemy behaviors. You will learn through detailed written explanations and architectural breakdowns designed to build your engineering confidence. This course is designed for aspiring gameplay programmers and developers who have a basic grasp of C++ and want to learn Unreal Engine's powerful gameplay framework. No prior experience with the Gameplay Ability System is required, as we start with foundational definitions and basic setups. Start building your gameplay programming foundation and bring your RPG combat ideas to life.
