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

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