{{函数详情
|函数名 = Function: vector llDetectedTouchST( 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 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 usually in the interval [0.0, 1.0] with the origin in the bottom left corner.[1] With some mesh objects, values of less than 0.0 and higher than 1.0 have been observed.

|注意事项=
*If index is out of bounds the script continues to execute without an error message.
*TOUCH_INVALID_TEXCOORD 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 event triggered is not a touch event.

{
integer touchFace = llDetectedTouchFace(0);
vector touchST = llDetectedTouchST(0);

// ZERO_VECTOR (<0.0, 0.0, 0.0> ... the origin) is in the bottom left corner of the face
// touchST.x goes across the face from the left to the right
// touchST.y goes up the face from the bottom to the top

 {{函数详情
 |函数名 = Function: vector llDetectedTouchST( integer index );
-|参数= 参数：integer index–Index of detection information index does not support negative indexes.
+|参数= 参数：整数索引—检测信息索引不支持负索引。
-|返回值= 返回值：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 usually in the interval [0.0, 1.0] with the origin in the bottom left corner.[1] With some mesh objects, values of less than 0.0 and higher than 1.0 have been observed.
+|返回值= 返回值：返回一个向量，该向量是prim被触摸的表面坐标。x和y矢量位置分别包含水平(s)和垂直(t)面坐标(<s, t, 0.0>)。每个组件通常位于区间[0.0,1.0]，原点位于左下角。在一些网格对象中，观察到的值小于0.0，大于1.0。
