Repo Demo

Course material on Utility AI: a decision-making approach where every action receives a continuous score computed through a response curve (linear, quadratic, logistic…). The NPC then picks the action with the best score.

Things to try

  • Adjust the curve parameters and watch the effect on the score.
  • Compare curve families to understand when to use each one.

The playable demo is embedded on this page (demoUrl field). Source code: see the repo link.
