A variety of sensors detect user interactivity with a scene, allowing authors to define animation responses in a device-independent, display-independent way.

User Interactivity Sensor Nodes

User interactivity is accomplished by sensing user actions, which create events that are sent via ROUTE connections.

Sensor output values are produced by CylinderSensor, KeySensor, PlaneSensor, StringSensor and TouchSensor nodes.
