LlDetectedTouchST

Template:Needs Translation/

函数名
Function: vector llDetectedTouchST( 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。

注意事项
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。
