keeping the orientation of a prim on a specific direction

is it possible to keep a prim oriented to a fixed direction?
like a compass?
by example keeping the direction only on the north ?

thank you

by moving it, yes.

if it's attached, it gets messy, because it reports attachment point rotation, which is relative to the av IIRC (and doesn't include any changes made by animation, which would trow it off for about anything but a hud)

in a physics environment llSetStatus will allow you keep the object from rotating around any of the 3 axis, but it can't be attached to the container... dunno how that would behave as an attachment

Thank you Void, in this case...what about a texture? can a texture to be set to a specific direction and keeping this even if the object changes the direction ?

thank you

rotation global = ZERO_ROTATION;

integer started = FALSE;

default
{
       state_entry()
       {
            llSetTimerEvent(0.25);
        }
    }
    
    timer()
    {
            llSetLocalRot(global / llGetRootRotation());
    }
}

yes I believe so, but annoying to code since you'd be converting the rotation of the object to offsets and rotation of image on the prim... possibly even per side for anything but a sphere. on the plus side IIRC you don't have to worry about bounds, since those are automatically scaled back to sane values (for instance rotations greater than +/-180deg, or offsets greater than +/-50%)... at least that's what I remember.

I did do a flight style hud bubble compass sometime back... and found that the easiest way was to texture the INSIDE of the sphere, and use setRot to cancel the difference in avatar rotation... it'd be even easier to do in a vehicle mounted setting.
