Pointing Stick

Made this to point at folk when its their turn at games lolz right. the useful tidbit is how it goes in the direction of what ever angle its pointing in.

<lsl> integer switch = TRUE; key user;

default {

   state_entry()
   {
       vector goal = <90, 0, 90>;
       llSetRot(llEuler2Rot(goal*DEG_TO_RAD));
       llSetText("Touch to activate", <0,1,0>, 1);
   }
   on_rez(integer x)
   {
       llResetScript();
   }
   touch_start(integer y)
   {
       if (switch)
       {
           user = llDetectedKey(0);
           llRequestPermissions(user, PERMISSION_TAKE_CONTROLS);
           llSetText("Touch to Release Controls", <1,0,0>, 1);
       }
       else
       {
           if (llDetectedKey(0) != user)     return;

       }
       switch = !switch;
   }
