Haven’t posted in a bit. Here’s a demo of something I’ve been working on. It allows you to create video game characters that will write their own lines and produce the audio through text-to-speech. It’s heavily cached so your game is always fast.

Key Features

Dynamic Dialogue Generation

  • Characters write their own dialogue in real-time
  • Context-aware responses based on game state
  • Personality-driven conversation patterns

Text-to-Speech Integration

  • Automatic audio generation from AI-written text
  • Character-specific voice styling
  • High-quality speech synthesis

Performance Optimization

  • Heavy Caching - Ensures your game stays fast
  • Intelligent cache management
  • Minimal runtime overhead

Technical Approach

The system is designed with performance in mind. By implementing aggressive caching strategies, we can provide rich AI-driven character interactions without sacrificing game performance. This is crucial for real-time gaming experiences where latency can break immersion.

Architecture Benefits:

  • Fast Response Times - Cached results eliminate AI generation delays
  • Scalable - Can handle multiple characters simultaneously
  • Reliable - Fallback systems ensure consistent behavior

Development Status

This is currently unreleased - something I’m using for a personal project. The system shows promising results for creating more dynamic and engaging NPCs in video games.

Future posts will dive deeper into the technical implementation and discuss how this fits into the broader landscape of AI-driven game development.
