llDetectedRot

Summary

Function: rotation llDetectedRot( integer number );

0.0	Forced Delay
10.0	Energy

Returns a rotation that is the rotation of detected object number.

• integer

number

number does not support negative indexes. Returns <0.0, 0.0, 0.0, 1.0> if number is not valid sensed object.

Caveats

• If number is out of bounds the script continues to execute without an error message.

//--// get compass facing of Avatar that touches this object //--//
