beet

Beet is behavior expressed as entity trees, using Observers for control flow. The entity-based approach is very flexible and allows for multiple behavior paradigms to be used together as needed.

Currently implemented paradigms:

• Behavior Trees

• Basic Utility AI

• LLM Sentence Similarity

• Reinforcement Learning

Hello World

// A demonstration of Fallback control flow
world.spawn(FallbackFlow)
  .with_children(|parent| {
    parent.spawn((
      LogOnRun::("Hello"),
      EndOnRun::failure(),
    ));
    parent.spawn((
      LogOnRun::("World"),
      EndOnRun::success(),
    ));
  })

Examples

The examples for beet are scene-based, meaning each example provides a scene for a common base app. As Bevy scene workflows are a wip, there are a few Placeholder types used for not-yet-serializable types like cameras, asset handles etc.

Most examples rely on assets that can be downloaded with the following commands, or manually from here.

curl -o ./assets.tar.gz https://storage.googleapis.com/beet-misc/assets.tar.gz
tar -xzvf ./assets.tar.gz
rm ./assets.tar.gz
