Usage Patterns
Event Dispatcher Pattern
1. Create Custom Event Dispatcher in source Blueprint
2. Bind to dispatcher in receiving Blueprint
3. Call dispatcher on events
4. Handle in bound functions
Blueprint Interface
1. Create Blueprint Interface asset
2. Add function signatures
3. Implement interface in Blueprints
4. Call interface functions on actors
Component-Based Design
1. Create Actor Component Blueprint
2. Implement reusable logic
3. Add component to actors
4. Access via Get Component
Best Practices
- Use functions for reusable logic
- Keep event graphs organized
- Comment complex sections
