Purpose

This skill enables the AI to assist with Unreal Engine development, focusing on creating 3D games and simulations using C++ and Blueprints for cross-platform projects.

When to Use

Use this skill for high-fidelity 3D game development, such as building multiplayer games, simulations, or VR experiences; when projects require advanced rendering, physics, or AI behaviors; or when integrating C++ with visual scripting for rapid prototyping.

Key Capabilities

• Cross-platform building with C++ and Blueprints: Supports Windows, macOS, Linux, and consoles via Unreal Build Tool (UBT).
• 3D rendering and physics: Leverage Niagara for visual effects or PhysX for simulations, e.g., using UPrimitiveComponent::SetSimulatePhysics(true); to enable physics on an object.
• Asset management: Handle blueprints (.uasset files) and C++ classes, with config in .ini files like Engine.ini for settings such as r.DefaultFeature.AutoExposure=True.
• Multi-threaded performance: Use async tasks via AsyncTask(ENamedThreads::GameThread, [](){ /* code */ }); for background operations.
• Integration with tools: Embed with Git for version control or external APIs via HTTP requests in Blueprints.

Usage Patterns

To start a project, generate a new Unreal project using UBT, then write C++ code or Blueprints for game logic. For C++ patterns, extend UCLASS objects and override methods; for Blueprints, create event graphs linked to actors. Always use the Editor for iterative testing: launch via UnrealEditor.exe MyProject.uproject, then compile changes with UnrealBuildTool.exe. Pattern for error-prone tasks: wrap code in try-catch for UObject operations and log via UE_LOG(LogTemp, Warning, TEXT("Message"));.
