|函数名 = Function: rotation llDetectedRot( integer number );
|参数= 参数：integer number–Index of detection information number does not support negative indexes.
|返回值= 返回值：Returns the rotation of detected object number.


|注意事项=
注意事项
*If number is out of bounds this function returns <0.0, 0.0, 0.0, 1.0> and the script continues to execute without an error message.
*Events that enable the llDetected* functions always return at least one detected item.
*Detection events are not raised if there is nothing detected.[1]
*The detection event's items detected parameter is initially never less than 1.[2]


|示例=
<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
string CompassDirection( rotation rRotBase )
{
  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
  return llList2String( gLstCompassPoints, iCompassPoint );
}
 
default{
  state_entry()
  {
    llSay( 0, "Touch me to get your compass facing" );
  }
 
  touch_start( integer vIntTouchCount )
  {
    integer vIntCounter = 0;
    do
    {
      llSay( 0,
             llDetectedName( vIntCounter )
             + " is facing "
              //-- next line gets avatar rotation and converts to compass direction
             + CompassDirection( llDetectedRot( vIntCounter ) ) );
