Definition

Caution

This component is no longer supported

This class must be instantiated by a script that implements the IMixedRealitySourceStateHandler, IMixedRealityInputHandler and IMixedRealityInputHandler<T>.

It must receive EventData arguments from OnInputDown(), OnInputUp(), OnInputChanged() and OnSourceLost().

This class manages the states of input necessary to calculate a proper grab position The eventData received on inputdown has the point on the target that was hit by the gaze; the mixedrealitypose - eventdata received on input changed contains the handposition in eventdata.inputdata.position It also contains useful retrieval functions.
