# LangChain Integration Examples
This directory demonstrates advanced AI-powered blueprint generation using LangChain integration with the UnrealBlueprintMCP system.
## ๐ง AI-Powered Features
### ๐ฃ๏ธ Natural Language Blueprint Generation
**File**: `nl_blueprint_generator.py`
- Convert natural language descriptions to blueprints
- Intelligent component selection based on description
- Automatic property inference from context
- Support for complex multi-component blueprints
### ๐ค Intelligent Assistant
**File**: `blueprint_assistant.py`
- Interactive AI assistant for blueprint development
- Context-aware suggestions and optimizations
- Automated code generation and property setup
- Integration with existing project assets
### ๐ฏ Smart Template Generator
**File**: `smart_template_generator.py`
- Generate blueprint templates from game descriptions
- Automatic architecture planning
- Component dependency analysis
- Performance optimization suggestions
### ๐ Code Analysis and Suggestions
**File**: `code_analyzer.py`
- Analyze existing blueprints for improvements
- Suggest optimizations and best practices
- Identify potential issues and bugs
- Generate documentation automatically
## ๐ Quick Start
1. **Install Dependencies**
```bash
pip install -r requirements.txt
```
2. **Setup API Keys**
```bash
export OPENAI_API_KEY="your-openai-api-key"
# or
echo "OPENAI_API_KEY=your-key" >> .env
```
3. **Test Basic Functionality**
```bash
python nl_blueprint_generator.py --description "A fast-moving enemy that shoots projectiles"
```
## ๐ Configuration
```python
# LangChain Configuration
LANGCHAIN_CONFIG = {
"model": "gpt-4",
"temperature": 0.7,
"max_tokens": 2000,
"system_prompt": "You are an expert Unreal Engine blueprint developer..."
}
```
## ๐ฏ Usage Examples
### Natural Language Generation
```python
from nl_blueprint_generator import NLBlueprintGenerator
generator = NLBlueprintGenerator()
result = await generator.generate_from_description(
"Create a player character that can jump, run, and shoot. "
"The character should have health and ammunition systems."
)
```
### Interactive Assistant
```python
from blueprint_assistant import BlueprintAssistant
assistant = BlueprintAssistant()
await assistant.start_session()
# User: "I need a weapon that fires in burst mode"
# Assistant will analyze, suggest components, and generate blueprint
```
### Smart Template Generation
```python
from smart_template_generator import SmartTemplateGenerator
generator = SmartTemplateGenerator()
template = await generator.create_game_template(
game_type="platformer",
features=["collectibles", "enemies", "power-ups"],
complexity="medium"
)
```
## ๐ง AI Prompt Engineering
### System Prompts
The examples use carefully crafted system prompts for optimal results:
```python
BLUEPRINT_EXPERT_PROMPT = """
You are an expert Unreal Engine blueprint developer with deep knowledge of:
- Component architecture and best practices
- Performance optimization techniques
- Blueprint visual scripting patterns
- Game development patterns and conventions
When generating blueprints, always consider:
1. Performance implications
2. Maintainability and modularity
3. Unreal Engine best practices
4. Component relationships and dependencies
"""
```
### Context Management
- Maintains conversation history for better understanding
- Uses project-specific context when available
- Adapts suggestions based on existing blueprints
## ๐ง Advanced Features
### Chain of Thought Processing
```python
# Example of multi-step blueprint generation
async def generate_complex_blueprint(description):
# Step 1: Analyze requirements
requirements = await analyze_requirements(description)
# Step 2: Plan architecture
architecture = await plan_architecture(requirements)
# Step 3: Generate components
components = await generate_components(architecture)
# Step 4: Create blueprint
blueprint = await create_blueprint(components)
return blueprint
```
### Multi-Agent Collaboration
```python
# Different AI agents for different tasks
class BlueprintTeam:
def __init__(self):
self.architect = ArchitectAgent() # High-level design
self.implementer = ImplementerAgent() # Detailed implementation
self.optimizer = OptimizerAgent() # Performance tuning
self.reviewer = ReviewerAgent() # Quality assurance
```
## ๐ Performance Optimization
### Token Usage Optimization
- Use template-based prompts to reduce token consumption
- Implement response caching for similar requests
- Batch multiple operations when possible
### Response Quality Improvement
- Use few-shot examples in prompts
- Implement validation and retry logic
- Use structured output formats (JSON schemas)
## โ ๏ธ Important Notes
### API Usage and Costs
- Monitor API usage and costs carefully
- Implement rate limiting for production use
- Use caching to reduce redundant API calls
- Consider using smaller models for simple tasks
### Quality Assurance
- Always validate AI-generated blueprints
- Test generated code in development environment
- Implement human review for critical blueprints
- Use version control for AI-generated assets
### Privacy and Security
- Never send sensitive project data to external APIs
- Use local models when possible for sensitive projects
- Implement proper API key management
- Review generated code for security implications
## ๐ Integration with Other Examples
- **Batch Operations**: Use AI to generate bulk blueprint specifications
- **Web Dashboard**: Display AI suggestions in the web interface
- **Game Setup**: Use AI to create initial project templates
