public class TouchSensor

extends Group

implements DeviceObserver

TouchSensor Node Class. Rules for Activation: -- A TouchSensor that has no children will activate if the selected geometry is any descendent of the TouchSensor's parent node. -- A TouchSensor that has children will activate only if the selected geometry is a descendent of the TouchSensor itself. -- If more than one TouchSensor fit the above criteria, then the TouchSensor that is lowest in the hierarchy will activate. -- If more than one TouchSensor that are siblings fit the above criteria, then the TouchSensor that was created first will activate. (When reading a scene from file, TouchSensors are created in the order in which they are listed in the file.)
