🎮 Transform Your Game with Truly Interactive NPCs

Welcome to the future of game development. NPC Builder for Unity brings your NPCs to life like never before — smarter, more responsive, and deeply customizable. This is our first Unity SDK, fully aligned with the latest version of NPC Builder, and it’s ready to revolutionize how your players experience characters in your world.


Highlights:

  • 🧠 Intelligent NPC Interactions

Connect your Unity project to NPCs built on our web platform. Characters can now respond to player actions through event-based logic, making each encounter more immersive and dynamic.

  • 🔐 Secure Authentication

Choose between Bearer Tokens for temporary sessions or permanent API Keys for ongoing access. You’re always in control.

  • 🗣️ Multilingual Support (English & Spanish)

Create and manage NPCs in both English and Spanish, switching languages easily from the Unity Inspector or web platform.

  • 💻 Cross-Platform Compatibility

Built for Unity. Works on Windows, Mac, and Linux — any system that can make HTTP calls.


Key Benefits:

  • ⚡ Easy Integration

Add complex, personality-rich NPCs to your game in minutes. No need to write networking code — just plug and play.

  • 🎨 Total Customization

Control how NPCs think, act, and speak from our powerful web dashboard. Adjust their behaviors, personalities, and responses to fit your game world perfectly.

  • 🧰 Full Event Support

Trigger NPC dialogue or actions in real-time based on in-game events like player proximity, item collection, or custom triggers.

  • 📞 Continuous Support

Our SDK is stable, tested, and production-ready. Still, we’re here for you. Contact our team any time through our support portal or email us at support@npcbuilder.com.
