Unreal Engine Cpp Pro

What it does

This skill provides expert-level guidance for developing with Unreal Engine 5 using C++. It focuses on writing robust, performant, and standard-compliant code, emphasizing best practices for UObject management, reflection system usage, and performance optimization within the Unreal Engine environment. This is specifically geared towards developers working with C++ in Unreal Engine projects.

When to use it

• Developing C++ code for Unreal Engine 5.x projects.
• Writing Actors, Components, or classes derived from UObject.
• Optimizing performance-critical sections of your Unreal Engine game.
• Debugging memory leaks or garbage collection issues.
• Implementing functionality intended to be exposed within Blueprints.

Key capabilities

• Guidance on UObject and Garbage Collection management (using UPROPERTY(), TStrongObjectPtr<>, IsValid() checks).
• Expertise in utilizing Unreal's reflection system (UCLASS(), USTRUCT(), UFUNCTION()).
• Performance optimization techniques, including disabling Tick when not needed, avoiding casts in loops, and using structs appropriately.
• Adherence to Epic Games’ coding standards and naming conventions (e.g., prefixes like T, U, A, F, E, I, S).
• Best practices for component lookup and interface implementation.

Example prompts

• "How do I properly manage UObject references to prevent memory leaks in Unreal Engine 5?"
• "What's the best way to expose a function from my C++ class to Blueprints?"
• "Can you show me an example of implementing an interface in Unreal Engine C++?"

Tips & gotchas

• This skill is specifically for Unreal Engine 5.x projects and C++ development; it's not suitable for Blueprint-only projects or other game engines.
• Always use UPROPERTY() for UObject member variables to ensure they are tracked by the Garbage Collector.
• Avoid using GetComponentByClass within Tick functions; instead, perform this lookup in PostInitializeComponents or BeginPlay.
