A comprehensive guide to implementing modern player input in Unreal Engine 5 using the Enhanced Input system. Learn how to set up Input Actions (IA_), Input Mapping Contexts (IMC_), modifiers, and triggers. Covers binding actions in both C++ and Blueprints, providing a data-driven approach to movement, looking, and general gameplay controls, moving beyond legacy input methods.

A comprehensive guide to building and controlling real-time visual effects (VFX) in Unreal Engine 5 using the Niagara system. Learn the System/Emitter/Module hierarchy, how to expose user parameters for game logic control, and methods for spawning and driving complex particle effects at runtime using both C++ and Blueprints. Ideal for gameplay-driven visual assets.

This skill provides comprehensive guidelines for writing idiomatic and efficient C++ code. It covers memory management, modern types, move semantics, templates, error handling, concurrency, and common anti-patterns to ensure safe and maintainable software development.

Interactively debug source code with the dap CLI: set breakpoints, step through execution line by line, inspect live variables and the call stack, evaluate expressions, and trace root causes across Python, Go, Node.js, Rust, and C/C++.

An advanced debugging skill designed for AI agents. It utilizes gdb-cli to provide intelligent assistance for C/C++ programs, enabling the analysis of core dumps, debugging live processes, and investigating complex issues like crashes, deadlocks, and memory corruption. It correlates runtime state inspection with source code context for deeper insights.

This expert guide provides comprehensive best practices for developing robust, high-performance C++ code within Unreal Engine 5.x. It covers critical topics such as UObject lifecycle management, adhering to Epic Games' strict coding conventions, optimizing performance-critical sections (e.g., avoiding unnecessary Ticking), and correctly using soft references for asset loading. Use this skill for professional game development tasks requiring deep knowledge of the Unreal reflection system and advanced C++ patterns.

Detects missing zeroization of sensitive data in C/C++/Rust source code and identifies zeroization removed by compiler optimizations, with assembly-level analysis and control-flow verification. Use for auditing code that handles secrets, keys, passwords, or other sensitive data.
