realXtend can run LSL scrpit no problem.

Hence, we will be able to use exist LSL command embedding in python to run the command.

The key script that is used:

To do a few things:

• IF (people within range) then
  • SHOUT to the person about being tracked for the FIRST time
  • Ask for permission to track user.
  • IF (POS/ROT not BOTH EQUAL ZERO) THEN
    • Get Time Stamp
    • Get Position Information
    • Get Rotation Information
    • Output into FILES?

}

Detecting Users in Range

//Setting detection range to 5 meters float range = 5.0;

default {

   //touch state.
   touch_start(integer numberDetected)
   {
        // activates the sensor. Look for avatars (i.e. not moving objects) on all sides of the object
        llSensor("", "", AGENT, range, PI); 
   }

   //When object sensed. Passed on number deteced as parameter
   sensor (integer numberDetected)
   {
       //Notify number and name
       string msg = "Detected " + (string)numberDetected + " avatar(s): " + llDetectedName(0);

       integer i = 0;

       while(numberDetected > ++i)//skips the first item which suits this application
       {
          msg += ", " + llDetectedPos(0) + llDetectedRot(0);
       }
       llWhisper(0, msg);
   }

   no_sensor()
   {
       llWhisper(0, "Nobody is near me at present.");
   }

} ==

integer perm = llGetPermissions(); vector CamVec; rotation CamRot; integer loopTime; //how frequently the loop is run

if (perm & PERMISSION_TRACK_CAMERA) // using & is important! perm is a bitmask!

{
 //Get Camera Position 3D Coordinate
 //Returns a VECTOR
 CamVec = llGetCameraPos();

 //Get Camera Rotation
 //Returns a ROTATION
 CamRot = llGetCameraRot();
 
 //Get User Name
 llRequestAgentData(llDetectedKey(0), DATA_BORN); 

 //Request creation date
   }
   dataserver(key queryid, string data) 
   {
       llSay(0, "You were born on: " + data);
   }

}

}
