Follower script tips

I've made a script (see below) that when in a prim makes the prim turn to face a target in the same sim and move fairly promptly to be close to it. It works. If I attach it to myself, I was expecting to move, but I stand still. Any ideas?

integer follow=TRUE;   //Are you to follow?
string  followTarget="poolside";   //Who you're meant to follow
integer followRange=10;    //How far away you're meant to be.
default
{
    state_entry()
    {
        llSensorRepeat(followTarget, NULL_KEY, AGENT | ACTIVE | PASSIVE, 96, PI, 0.2);
    }
    sensor(integer detected)
    {
        vector where=llDetectedPos(0);
        rotation look=llDetectedRot(0);
        vector here=llGetPos();
        float distance=llVecDist(here, where);
        if(distance > followRange)
        {
            vector run=where - here;
            float cos=(run.x / distance);
            float sin=(run.y / distance);
            vector aim=<0,0, llAcos(cos)>;
            if(sin < 0)
            {
                aim+=<0,0,PI>;
            }
            llSetRot(llEuler2Rot(aim));
            vector target=here + <cos * 2, sin * 2, (run.z / distance * 2)>;
            llSetPos(target);
        }
    }
    no_sensor()
    {
        llInstantMessage(llGetOwner(), "Cannot detect follow target within range.");
    }
}

This is to add a function to something else, so there are ways to turn it off etc, although not in this version.

Any help please?

Kinematics don't work on avatars - you need to use kinetic tools like llRotLookAt(), llMoveToTarget() and thier buddies.
Wiki page for reference.

Thank you, now to go and experiment!

And having experimented, it works, thanks for the tip!
