Summary

Function: string llDetectedName( integer number );

Returns a string that is the name of detected object or avatar number

• integer number Index of detection information

number does not support negative indexes. Returns NULL_KEY if number is not with in range.

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]
