Documentation

• Unreal Engine 5.4 or 5.5+
• Windows 10 or Windows 11 (64-bit)
• Visual Studio 2022 with the C++ game development workload installed
• Active internet connection — the plugin calls the Anthropic API at runtime

• Right-click your .uproject → Generate Visual Studio project files
• Open the generated .sln in Visual Studio 2022
• Set configuration to Development Editor and platform to Win64
• Build → the plugin compiles alongside your project
• Launch the Editor from VS or double-click your .uproject

• Go to console.anthropic.com and sign up or log in.
• Navigate to API Keys in the left sidebar → Create key.
• Copy the key — it starts with sk-ant-.

Edit → Project Settings → Plugins → Mungol AI
  API Key:  sk-ant-api03-...

The key is stored in your local Saved/Config/WindowsEditor/EditorPerProjectUserSettings.ini and is never committed to source control.

AI reads the selected nodes' class names, pin types, and default values, then explains what the logic does in plain language. Useful for onboarding into unfamiliar Blueprints or preparing to refactor inherited code.

AI suggests restructuring — removing redundant casts, replacing macros with functions, improving event flow. Returns a step-by-step list with reasoning for each change.

AI generates a UCLASS with equivalent logic as UPROPERTY and UFUNCTION members. Paste into a new .h / .cpp pair and trigger Live Coding to compile without restarting the Editor.

• Describe the class or function you need in plain language.
• AI generates a matching UCLASS / USTRUCT / UFUNCTION pair with correct UE5 macros.
• Review the output in the built-in diff panel.
• Click Write to file — the plugin creates the .h and .cpp in your module's Source/ automatically.
• Trigger Live Coding (Ctrl+Alt+F11) to compile without restarting the Editor.

C++ Writer automatically injects your project's module name, UE version, and existing class list so the AI generates code that compiles against your project without manual include path adjustments.

/spawn     → Spawn actors via AI prompt
/material  → Create or edit materials
/animate   → Generate animation blueprints
/cpp       → Open C++ Writer with your prompt pre-filled
/bp        → Build Blueprint logic from a description
/optimize  → Analyse the active level for performance issues
/explain   → Explain the selected asset or highlighted code

• Free-text (no slash prefix) sends directly to Claude as a general query.
• Recent commands are saved — press ↑ to cycle through history.
• Press Escape or click outside to close.
• To keep the palette open, enable Stay Open on Focus Loss in Project Settings → Mungol AI → Palette.

Every message automatically includes:

• Active level name and actor count
• Selected actors and their component hierarchy
• Current Blueprint or C++ file open in the editor
• Project name and UE version

• Ask follow-up questions in the same session — Claude remembers earlier turns.
• Start a new conversation (New Chat button) when switching to an unrelated task to avoid confusing earlier context.
• Paste compiler error output directly — Claude reads the full stack trace and suggests a fix.
