rotation llDetectedRot(
  1. integer number// Index of the detection information.
);
Returns
rotation
Energy
10

Returns the rotation of the detected object or avatar specified by number, or <0.0, 0.0, 0.0, 1.0> if number is not a valid offset index.

Returns <0.0, 0.0, 0.0, 1.0> if number is not valid sensed object.

How to use
rotation result = llDetectedRot(0);
