llDetectedRot

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

–

Index of detection information

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

Specification

llDetected* functions only work if called from within Detection events (collision, collision_start, collision_end, sensor, touch, touch_start, touch_end) or in functions called by Detection events. They will fail silently and return unusable values if called during other events.

Caveats

• If number is out of bounds the script continues to execute without an error message.
• Events that enable the llDetected* functions always return at least one detected item.
  • Detection events are not raised if there is nothing detected.^[1]
  • The detection event's items detected parameter is initially never less than 1.^[2]

1. ^ The exception is no_sensor but it doesn't enable llDetected* functions.
2. ^ Like all event parameters, the user can overwrite the initial value.
