A collection of scripts and resources for implementing utility-based AI in Godot.
To install, follow the latest instructions for installing plugins in the Godot documentation.
- 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.
