## Topics

### Creating a behavior tree component

[`init(behaviorTree:availableBehaviorTrees:)`](/documentation/RealityKit/BehaviorTreeComponent/init(behaviorTree:availableBehaviorTrees:))

### Accessing behavior trees

[`behaviorTree`](/documentation/RealityKit/BehaviorTreeComponent/behaviorTree)

Accesses the current behavior tree. Note that setting the behavior tree to a tree not in
`availableBehaviorTrees` will add a uniquely-named entry for the tree in `availableBehaviorTrees`.

[`availableBehaviorTrees`](/documentation/RealityKit/BehaviorTreeComponent/availableBehaviorTrees)

All the behavior trees that this component can access.
