I have seen people with objects that look at the nearest person, browsed the entire library and couldn't find one for it, anyone have of these laying around?

you can have this:
CODE

default
{
    state_entry()
    {
        llSetStatus(STATUS_ROTATE_X | STATUS_ROTATE_Y | STATUS_ROTATE_Z, TRUE);
        llSetStatus(STATUS_PHYSICS, TRUE);
        llSensorRepeat("",llGetOwner(),AGENT,96.0,PI,1.0);
    }
    sensor(integer Number)
    {
            vector position=llDetectedPos(0);
            vector Offset=< -1.0, 0.0, 1.5>;
            position+=Offset;
            llSetStatus(STATUS_PHYSICS, TRUE);
            llMoveToTarget(position,0.4);
            llLookAt(llDetectedPos(0)+<0.0, 0.0, 1.0>,0.5,0.5);
    }
}

It will follow you and point the prim's Z-axis to you (you are the owner)
To make it look at the nearest person replace llGetOwner with NULL_KEY and find out wich agent is closest in the sensor event handler.
Happy scripting:)

I found this very useful, however, how would I make the object point on its X axis instead of the Z axis, (and its not working by changing <0.0,0.0,1.0> to <1.0,0.0,0.0>;). Thanks in advance.

i think you can do that with llRotLookAt



otherwise, you can make the root prim invisible,and rotate the rest of the object to fix it

unfortunately, llRotLookAt needs a rotation to look at, not a position. Unless there's some way to convert my position to a rotation, I'm at a complete loss.

Try what Ruthven suggested in post #4 or just create another prim, rotate z axis in the direction you want in regard to the rest of the build, make it invisible if necessary and make it the root prim when you link it together. With the script in the new root prim, the object will turn correctly.

CODE

default
{
state_entry()
{
llSensorRepeat("", "", AGENT, 96.0, PI, 0.5);
}

sensor(integer number)
{
vector direction = llVecNorm(llDetectedPos(0) - llGetPos());
rotation fwd = llRotBetween(<1.0, 0.0, 0.0>, direction);
llRotLookAt(fwd, 1.0, 1.0);
}
}


Something like that should work, although I can't guarantee it will compile, since I wrote it in the reply window.
