Utility AI for Godot

A collection of scripts and resources for implementing utility-based AI in
Godot.

Installation

To install, follow the latest instructions for installing
plugins
in the Godot documentation.

Getting Started

• Define abstract behaviors in terms of one or more considerations.
• Create response curves to determine the utility of your behaviors.
• Create concrete options combining a behavior, a specific decision
  context, and an in-game action to perform if the behavior is chosen.
• Choose between available options based on their utility score.

Behaviors, considerations, response curves and options can be edited directly
in the Inspector:

Since actions and contexts describe the interaction between the utility AI
system and the rest of the game, their implementations are game-specific.
Simple examples of using the plugin are available in the examples
directory.

Additional documentation is available in Godot's help window after installing
the plugin.
