Summary

Function: key llDetectedKey( integer number );
0.0 Forced Delay
10.0 Energy

Returns a key that is the UUID of the detected object or avatar number.

• integer number Index of detection information

number does not support negative indexes. Returns an empty key if number does not correspond to a valid sensed object or avatar.

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]

Examples

default
{
    touch_start(integer num_detected)
    {
        llSay(0, "touch_start event: key of avatar touching: " + (string) llDetectedKey(0) );
    }
}

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.
