physical follower help.

I am trying to make a physical object follow me above my shoulder.
the problem i am running into is that its basing its vector on the world axis. so no matter which way i turn it stays in the same place unless i move. its not staying above my shoulder.
how can i get it to go off my avatars local axis?
here is a sample of one of my attempts. a friend tried to help me out with the math.

vector rad;
rotation rot;
default
{
state_entry()
{
llSensorRepeat

("",llGetOwner

(),AGENT,50.0,TWO_PI,.1);
}

sensor(integer total_number)
{
rot = llDetectedRot(0);
rad = llRot2Euler(rot);
llMoveToTarget(llDetectedPos(0)+ <llSin(rad.x), -llCos(rad.x),1>,.1);
llRotLookAt(rot,1,1);
}
}


I have tried a few different ways but this is the basic script all my attempts have been based on. all thats changed is the math i use.
can anyone lend a hand?

for a start try: llMoveToTarget(llDetectedPos(0)+ rad, .1);

keep it simple ......

It is not clear what direction you want it to face, but assuming it is the same as the av, then:
llSetRot( llDetectedRot(0) ); (thats the simple version)

Happy scripting

Thank you for the reply. but my problem is not its rotation.
it simply that.. well lets say my object is sitting above my right shoulder.
then i turn 90 degrees to the right. suddenly my object is in front of my face instead of over my shoulder.
I want it to stay over my shoulder.

Edit: sorry didnt see that you have me a suggestion on the llMoveToTarget
with that line it seems to bug out. one minute its about where it should be. then i turn and it slams into the ground.

this is a free follower I picked up god knows where:

default
{
    state_entry()
    {
        vector pos = llGetPos();
        llSetStatus(STATUS_ROTATE_X | STATUS_ROTATE_Y, FALSE);
        llSetStatus(STATUS_PHYSICS, TRUE);
        llSleep(0.1);
        llMoveToTarget(pos,0.1);
        key id = llGetOwner();
        llSensorRepeat("",id,AGENT,20,2*PI,.4);
    }

    sensor(integer total_number)
    {
        vector pos = llDetectedPos(0);
        vector offset =<-1,0,0>;
        pos+=offset;
        llMoveToTarget(pos,.3);        
    }
}

it will place the object at 'offset' relative to your av...
try play with that

That certainly is a different way to do it.
sadly it does the same thing my script does.
but ill take a look at it and see if maybe this way of doing it is any better than mine.

Oh i seem to have solved it.
Instead of rad.x i needed rad.z
i noticed that when in mouse look when i looked up and down the object moved left and right.
