SensorBody

A sensor attached to a body-object with local position \(\pLocB\). As a difference to SensorObject, the body sensor needs a local position at which the sensor is attached to. The sensor measures OutputVariableBody and outputs values into a file, showing per line [time, sensorValue[0], sensorValue[1], …]. Use SensorUserFunction to modify sensor results (e.g., transforming to other coordinates) and writing to file.

The item SensorBody with type = ‘Body’ has the following parameters:

• name [type = String, default = ‘’]:

  sensor’s unique name
• bodyNumber [type = ObjectIndex, default = invalid (-1)]:

  body (=object) number to which sensor is attached to
• localPosition [\(\pLocB\), type = Vector3D, size = 3, default = [0.,0.,0.]]:

  local (body-fixed) body position of sensor
• writeToFile [type = Bool, default = True]:

  True: write sensor output to file; flag is ignored (interpreted as False), if fileName=’’
• fileName [type = String, default = ‘’]:

  directory and file name for sensor file output; default: empty string generates sensor + sensorNumber + outputVariableType; directory will be created if it does not exist
• outputVariableType [type = OutputVariableType, default = OutputVariableType::_None]:

  OutputVariableType for sensor
• storeInternal [type = Bool, default = False]:

  true: store sensor data in memory (faster, but may consume large amounts of memory); false: internal storage not available
• visualization [type = VSensorBody]:

  parameters for visualization of item

The item VSensorBody has the following parameters:

• show [type = Bool, default = True]:

  set true, if item is shown in visualization and false if it is not shown
