{{函数详情
|函数名 = Function: vector llDetectedTouchPos( integer index );
|参数= 参数：integer index–Index of detection information index does not support negative indexes.
|返回值= 返回值：Returns the vector position where the object was touched in region coordinates, unless it is attached to the HUD, in which case it returns the position in screen space coordinates.


|注意事项=
注意事项
*HUD attachments currently return coordinates relative to the center of the screen rather than the attachment point. SVC-3425
*If index is out of bounds the script continues to execute without an error message.
*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.

示例1
<pre>
default
{
    touch_start(integer num_detected)
    {
        llWhisper(0, "Pos clicked: " + (string)llDetectedTouchPos(0));
    }
}
</pre>

示例2
<pre>
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.
 
    integer point = llGetAttached();
    vector offset;
 
    if      (point == ATTACH_HUD_TOP_RIGHT)    offset = <1.0, 0.933,-0.5>;
    else if (point == ATTACH_HUD_TOP_CENTER)   offset = <1.0, 0.000,-0.5>;
    else if (point == ATTACH_HUD_TOP_LEFT)     offset = <1.0,-0.933,-0.5>;
    else if (point == ATTACH_HUD_BOTTOM_LEFT)  offset = <1.0,-0.933, 0.5>;
    else if (point == ATTACH_HUD_BOTTOM)       offset = <1.0, 0.000, 0.5>;
    else if (point == ATTACH_HUD_BOTTOM_RIGHT) offset = <1.0, 0.933, 0.5>;
 
    //return (pos - llGetLocalPos()) + (offset * llGetLocalRot());
    return ((offset - llGetLocalPos()) + pos) / llGetLocalRot();
