MetaMix3D AI NPC Dialogue System + World Knowledge for Unity helps developers create interactive NPCs that players can actually talk to.
This package is designed for developers who want a practical NPC dialogue workflow without building everything from scratch. It includes a plug-and-play NPC setup, dialogue UI, JSON-based offline dialogue support, and world knowledge integration for smarter conversations.
You can drag and drop NPC prefabs into your Unity scene, connect dialogue data, and start testing NPC conversations quickly.
What this package includes
- AI NPC dialogue system
- World knowledge system
- JSON-based offline dialogue support
- Plug-and-play Unity setup
- NPC prefab workflow
- Dialogue UI / chat component
- Example dialogue files
- Sample NPC prefabs
- Demo scene
- Documentation
Main features:
Plug-and-play setup
Add an NPC prefab to your scene, assign dialogue data, and test conversations inside Unity.
JSON-based offline dialogue
Use local JSON files to define dialogue content and response flow for offline mode.
World knowledge support
NPCs can answer questions related to game locations, lore, and environment-specific knowledge.
Unity integration
Simple inspector workflow for assigning NPC dialogue, chat UI, and interaction settings.
Flexible workflow
Supports both:
- Offline local dialogue mode
- Extended AI-based workflow when connected to your external backend
(Optional) AI Cloud Mode
This package includes an offline dialogue system using JSON files that works entirely inside Unity without any internet connection.
For developers who want more advanced AI-powered NPC conversations, the system can optionally connect to an external AI backend.
Online AI features may require:
- API key configuration
- Internet connection
- Subscription or usage-based billing depending on the external service used
Offline mode works independently and does not require any external services.
Important setup notes:
• After importing the package into a fresh project, TextMesh Pro Essential Resources may need to be imported from Window > TextMeshPro > Import TMP Essential Resources.
• The included demo scene may use Unity Starter Assets / starter kit style character content for demonstration purposes only.
