Summary

Function: integer llDetectedTouchFace( integer index );

Returns an integer that is the index of the face the avatar clicked on.

• integer index – Index of detection information

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.

Caveats

  • If index is out of bounds the script continues to execute without an error message.
  • TOUCH_INVALID_FACE 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.

   {
       integer touchedFace = llDetectedTouchFace(0);

       // PUBLIC_CHANNEL has the integer value 0

           llSay(PUBLIC_CHANNEL, "Sorry, your viewer doesn't support touched faces.");
       else
       {
           // store the original color
           vector originalColor = llGetColor(touchedFace);

           // color detected face white
           llSetColor(<1.0, 1.0, 1.0>, touchedFace);
           llSleep(0.1);

           // color detected face black
           // ZERO_VECTOR has the vector value <0.0, 0.0, 0.0>
           llSetColor(ZERO_VECTOR, touchedFace);
           llSleep(0.1);

           // color detected face back to original color
