| 函数名
|
| Function: vector llDetectedTouchUV( integer index );
|
| 参数：整数索引—检测信息索引不支持负索引。
|
| 返回值：返回一个矢量，该矢量是prim被触摸的地方的纹理坐标。x和y矢量位置分别包含水平(u)和垂直(v)纹理坐标(<u, v, 0.0>)。与llDetectedTouchST类似，除非纹理重复被设置为非默认值，否则每个组件的间隔将为[0.0,1.0]。增加或减少面部重复的纹理将相应地改变这个间隔。此外，与llDetectedTouchST不同的是，改变纹理的旋转会改变这个函数的结果。

注意事项
- 如果索引超出界限，脚本将继续执行，不会出现错误消息。
- TOUCH_INVALID_TEXCOORD在…
- 头像查看器不支持面部触摸检测。
- 检查是否支持face touch检测，检查llDetectedTouchFace返回。
- 触摸已经离开了表面的prim。
- 触摸太靠近脸的边缘，无法确定位置。
- 触发的事件不是触摸事件。

示例1
default

touch_start(integer total_number)
{
integer face = llDetectedTouchFace(0);
vector touchUV = llDetectedTouchUV(0);
// ZERO_VECTOR (<0.0, 0.0, 0.0> ... the origin) is in the bottom left corner of the texture
// touchUV.x goes across the texture from left to right
// touchUV.y goes up the texture from bottom to top
if (face == TOUCH_INVALID_FACE)
llWhisper(PUBLIC_CHANNEL, "Sorry, your viewer doesn't support touched faces.");
else if (touchUV == TOUCH_INVALID_TEXCOORD)
llWhisper(PUBLIC_CHANNEL, "Sorry, the touch position upon the texture could not be determined.");
else

+ "\ntouchUV.x = " + (string)touchUV.x
