Neocortex Godot SDK brings voiced NPCs to Godot 4.7

Neocortex announced its Godot SDK 0.2.0 on November 10. The open-source add-on works with Godot 4.7 or later and needs a Neocortex account and API key. It gives game developers a starter scene for NPC dialogue and a GDScript interface for connecting a character’s actions to game logic. Announcement · SDK 0.2.0 · Requirements

Start with a Godot chat scene

Enable the add-on in Project Settings and save the API key in the Neocortex dock. Under Project → Tools → Neocortex, choose Complete Voice Chat or Complete Text Chat, then assign a character. The voice setup supports push-to-talk or voice detection. Replies arrive in lines with an emotion on each line, which your scene can use to update an animation or portrait as the character speaks.

Wire character actions to GDScript

Use register_action on NeocortexSmartAgent to connect an action keyword to a function in your project. An action can carry the ID of a NeocortexInteractable in the scene. For a shopkeeper who opens a door, the game can check that the target is the right door and that the current quest allows it before running the animation. The vendor’s Interactables sample demonstrates how the character takes directions that refer to objects in the scene. Action interface · SDK samples

The quick start says a Godot export carries the configured API key. Neocortex recommends using a separate key for each release and setting per-player and per-character credit caps. The SDK includes a Usage Gating sample, and its voiced chat can fall back to text when credits run out. Export setup · Usage limits · Chat modes
