Emitter always horizontal?

[Doctor Visage]

Hello! This part of the script allows to change the position of the emitter depending on the speed. But how to add here the possibility that the emitter is always exactly horizontal?

(and even better is it possible to make the emitter always at the same height and horizontally? 🤩)' <- regardless of speed and throttle.

Particle system is a ribbon, and due to the tilt of the vehicle, the ribbon sometimes goes wrong.

vector emitter_pos_max = < -1.15, 0.0, -0.170 > ;
vector emitter_pos_min = < -1.15, 0.0, -0.250 > ;
vector emitter_pos_range;

float speed_max = something;
float current_speed;

default
{
    state_entry ()
    {
        emitter_pos_range = emitter_pos_max - emitter_pos_min;
    }

    some_event ()
    {
        llSetLinkPrimitiveParamsFast (emitter_link_number, 
        [
            PRIM_POS_LOCAL, emitter_pos_min + (emitter_pos_range * (current_speed / speed_max))
        ]);
    }
}

Doc, nobody has answered as probably because is not clear what you mean by horizontal. Like horizontal to what ?
