Summary
Function: rotation llDetectedRot( integer number );38 | Function ID |
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.
