destroyElement problem

[Padul]

serverside

	local fb={}

	if policeSigState == 0 then
		setElementData ( playerOccupiedRadiolka ,"radiolka:signalsstate",1)
		fb.wuwuni = createObject ( 1845, x , y , z , xr , yr, zr )
		attachElements ( fb.wuwuni , playerOccupiedRadiolka, -0.5 , -0.05 , 0.9 )
	elseif policeSigState == 1 then
		setElementData ( playerOccupiedRadiolka ,"radiolka:signalsstate",0)
		destroyElement ( fb.wuwuni )
	end

	WARNING: Bad argument @ 'destroyElement' [Expected element at argument 1, got nill]
	

can someone explain me that and maybe help :)?

the problem is that i have more than one car that will have attached object wuwuni, it appears that if i create object on two vehicles then its possible to me to destroy element on the first vehicle

Try this (using an element data so it's the vehicle who is in charge to keep a reference to wuwuni instead of a server variable):

if policeSigState == 0 then
    local wuwuni = createObject ( 1845, x , y , z , xr , yr, zr )
    setElementData ( playerOccupiedRadiolka ,"radiolka:signalsstate",1)
    setElementData ( playerOccupiedRadiolka ,"radiolka:signalsobject", wuwuni )
    attachElements ( wuwuni , playerOccupiedRadiolka, -0.5 , -0.05 , 0.9 )
elseif policeSigState == 1 then
    setElementData ( playerOccupiedRadiolka ,"radiolka:signalsstate",0)
    local wuwni = getElementData ( playerOccupiedRadiolka , "radiolka:signalsobject" )
    if wuwni and isElement( wuwni ) then
        destroyElement ( wuwuni )
    end
end

if policeSigState == 0 then
	local wuwuni = createObject ( 1845, x , y , z , xr , yr, zr )
	setElementData ( playerOccupiedRadiolka ,"radiolka:signalsstate",1)
	setElementData ( playerOccupiedRadiolka ,"radiolka:signalsobject", wuwuni )
	attachElements ( wuwuni , playerOccupiedRadiolka, -0.5 , -0.05 , 0.9 )
elseif policeSigState == 1 then
	setElementData ( playerOccupiedRadiolka ,"radiolka:signalsstate",0)
	local wuwni = getElementData ( playerOccupiedRadiolka , "radiolka:signalsobject" )
	if wuwni and isElement( wuwni ) then
		destroyElement ( wuwuni )
	end
end
