Summary

Function: string llDetectedName( integer item );

Returns a string that is the name of the detected item.

• integer item Index of detection information

item does not support negative indexes. Returns NULL_KEY if item is not valid.
If the item detected is an avatar then the legacy name is returned.

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 item is out of bounds this function returns NULL_KEY and 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]

Examples

<lsl> default {

   touch_start(integer num_detected)
   {
       key id = llDetectedKey(0);
       // legacy name, i.e. "John Doe" or if lastname Resident "John Resident"
       string name = llDetectedName(0);
       // PUBLIC_CHANNEL has the integer value 0
       llSay(PUBLIC_CHANNEL,
           "The avatar with the key'" + (string)id + "' is named '" + name + "'.");
   }

}
