|函数名 = Function: rotation llDetectedRot( integer number );
|参数= 参数：检测信息号的整数索引不支持负索引。
|返回值= 返回值：返回检测到的对象号的旋转。


|注意事项=
注意事项
*如果数字超出界限，这个函数返回<0.0,0.0,0.0,1.0>，脚本继续执行，没有错误消息。
*启用lldetect *函数的事件总是返回至少一个检测到的项。
*如果没有检测到任何东西，则不引发检测事件。
*检测事件的项检测参数最初不小于1。

<pre>
//--// get compass facing of Avatar that touches this object //--//
 
 //-- list of compass directions starting at East, rotated clockwise
list gLstCompassPoints = [ "East", "NorthEast", "North", "NorthWest", "West", "SouthWest", "South", "SouthEast" ];
 
 //-- convert rotation to z-axis compass direction

  integer iCountCompassPoints = llGetListLength(gLstCompassPoints);
   //-- convert rotation to a direction
  vector vDirection = <0.0, 1.0, 0.0> / rRotBase;
   //-- take the direction and determine the z rotation
  float fAngle = llAtan2(vDirection.x, vDirection.y);
   //-- take the angle and find the compass point
  integer iCompassPoint = llRound(fAngle * iCountCompassPoints / TWO_PI);
   //-- convert to string
