Summary

Function: string llDetectedName( integer item );
0.0 Forced Delay
10.0 Energy

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)
   {
       integer i = 0;
       do
           llSay(0, llDetectedName(i) + "'s key is " + (string) llDetectedKey(i));
       while(num > ++i);
   }

}

</lsl>

Footnotes

  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.
