Activate Sensor

The Activate Sensor Behavior (beActivateSensor) enables Sensor on an Entity for as long as the behavior is active. 

To use an Activate Sensor Behavior a Perception Locator must be mapped to the Crowd Field (directly or through the Crowd Manager Node).

Sensors don't have any visible effect on the Crowd simulation. They output the detected objects and their distance. This sensor data can then be used in Channel Operators through the Sensor Input Channel Operator.
