SmokeShell not in house (properly) creatable?

[roguetrooper 2]

When you are in a house and have this script being executed, the smokeshell always falls through stairs etc onto the first floor (so to speak: where getposATL player select 0 = 0)

_pos = getposATL player;
_s   = createVehicle ["SmokeShell", _pos, [], 0, "NONE"];
_s setpos _pos;

Is there a way to create a smokeshell on the very position of the player in a building (esp. concerning the height) ?

Try creating it a bit higher , it's probably falling through the floor
