Emblem-important-red.png Pre-release Documentation Warning!

This function is not available yet. This documentation was written prior to its final release so it may not match the final implementation.

Summary

Function: vector llDetectedTouchST( integer index );

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.

• integer index 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.
  • 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.
