Interactables

An Interactable is the object that is acted upon (hovered or selected) by the Interactors on your hands or controllers. An Interactable can limit the maximum number of Interactors that can hover or select it at a time.

You can have multiple Interactables for a given object. For example, to make a button that can interact with both rays and poke, you can add both a RayInteractable and PokeInteractable to the button’s GameObject(s). You can also use an InteractableGroup, which allows a group of Interactables to share properties like max hovering and Interactor selection.

Subclasses of Interactable will have relevant data (or can be configured with such data) that associated Interactors can then use to make decisions about hovering and selection. For example, a RayInteractable may be configured with a Surface that is then used for raycasting in a RayInteractor.

Interactables often don’t handle the general interaction logic you find with Pointer Events or when modifying transforms and passing off those responsibilities via events. For instance, surface-based interactions may be handled by PointableElements, whereas grab-centric transform updates may be handled by Grabbable objects.
