Summary

Function: vector llDetectedTouchST( integer index );

0.0	Forced Delay
10.0	Energy

Returns a vector that is the surface coordinates for where the prim was touched. The x & y vector positions contain the horizontal (s) & vertical (t) face coordinates respectively (<s, t, 0.0>). Each component is in the interval [0.0, 1.0].

Returns <-1., -1., 0.> if the avatar's viewer does not support this feature.

Index of detection information

index does not support negative indexes. For the touch category of events only.

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 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.^[1]
  • The detection event's items detected parameter is initially never less than 1.^[2]
