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.

How to use
vector result = llDetectedTouchPos(0);

Caveats

Section titled “Caveats”
  • TOUCH_INVALID_VECTOR 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 event triggered is not a touch event.

Examples

Section titled “Examples”
Example 1
default
{
    touch_start(integer num_detected)
    {
        llWhisper(0, "Pos clicked: " + (string)llDetectedTouchPos(0));
    }
}
Example 2
vector GetRealTouchPos(vector pos)
{
//  By Ariu Arai for free use to anyone
//  Returns a useful HUD Position Vector from the llDetectedTouchPos(); function
//  USE: vector pos = GetRealTouchPos(llDetectedTouchPos(0)); .. Etc.
//  This function is intended to be used to move child prims to where the user clicks. This does not work on the root prim.
