# Interactor Events

These are events that can be hooked into in the editor the same way you would respond to a UI button press. These apply to Interactors - objects that can interact with Interactables.

The UI Hover Entered and UI Hover Exited events are not available on all interactor components. Only those interactors that implement [`IUIHoverInteractor`](xref:UnityEngine.XR.Interaction.Toolkit.UI.IUIHoverInteractor) and enable UI Interaction with the [XR UI Input Module](xref:xri-ui-input-module), such as [XR Poke Interactor](xref:xri-xr-poke-interactor), will have these events.
