index does not support negative indexes.
For the touch category of events only. The prim that was touched may not be the prim receiving the event, use llDetectedLinkNumber to check for this; likewise you can use llDetectedTouchFace to determine which face was touched.
Specification
llDetected* functions can be called anywhere but will only return non-default values if called from within Detection events and functions called by Detection events.
Caveats
- If index 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 (with the slight exception of no_sensor but it doesn't enable llDetected* functions).
- The event detection count parameter value is initially never less than 1.
- TOUCH_INVALID_VECTOR is returned when...
- The avatar's viewer does not support face touch detection.
- The touch has moved off the surface of the prim.
- The event triggered is not a touch event.
