Class UUxtGrabTargetComponent

Interactable component that listens to grab events from near pointers.

A pointer that starts grabing while near the actor is considered a grabbing pointer. The grab is released when the pointer stops grabing, regardless of whether it is still near or not.

The GrabComponent does not react to grabbing pointers by itself, but serves as a base class for manipulation.
