Summary

Function: vector llDetectedTouchST( integer index );

342	Function ID
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].

<-1.0, -1.0, 0.0> is returned when the surface coordinates cannot be determined. See Caveats for further details.

Index of detection information

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

Caveats

• If index is out of bounds the script continues to execute without an error message.<-1.0, -1.0, 0.0> is returned when...
• The avatar's viewer does not support face touch detection.
  • To check if face touch detection is supported check the return of llDetectedTouchFace.
• The touch has moved off the surface of the prim.
• The touch happened too close to the edge of the face to determine a location.
• The triggering event is not a touch event.
