Motive Engine

A lightweight Unity package for building NPCs that choose actions using transparent, tunable scores instead of opaque black-box behaviour.

What it returns

Motive Engine evaluates agent traits against context signals and returns a transparent decision payload your game can route into existing systems.

  • selected motive
  • confidence
  • ranked motives
  • explanation
  • response key

What it does not do

The product boundary stays clean. Response keys are hooks, not a hidden gameplay stack.

  • does not move NPCs
  • does not animate, fight, or pathfind
  • does not run dialogue trees, GOAP, or LLM NPC behavior
  • does not execute gameplay responses

Package status

Unity-ready, not public-download yet.

Motive Engine is tested as a UPM package and Asset Store export, but the public website should route access through contact until the release channel is decided.

Decision Labs

Four sample scenes, one decision layer.

Tactical, horror, faction, and narrative samples show how Motive ranks intent, confidence, explanations, and response keys without owning the rest of your game.
