Interface IXRInteractable

An interface that represents an Interactable component that controls how a GameObject interacts with an Interactor component. An example is a Grab Interactable which can be picked up and moved by an Interactor.

public interface IXRInteractable
Remarks

When scripting, you can typically write custom behaviors that derive from XRBaseInteractable or one of its derived classes rather than implementing this interface directly.
