attempt to compare boolean with number

[Robis]

I have an error, which is hard to fix ( for me )

can anyone help?

SCRIPT:

if getElementData(getElementData(veh,"parent"),"fuel") <= 0 then

ERROR:

attempt to compare boolean with number  [DUP x21]

This looks like dayz.

You should make a check to see if getElementData(veh,"parent") is an element and if its "fuel" data is a number.

local parent = getElementData(veh,"parent")
if isElement(parent) and tonumber(getElementData(parent,"fuel"))then
  if getElementData(parent,"fuel") <= 0 then
    -- code

I cant understand?

Heres my function - how should i replace with it?

function setEngineStateByPlayer (playersource)
	if getElementData(getElementData(veh,"parent"),"fuel") <= 0 then
		outputChatBox("This vehicle tank is empty!", playersource, 255, 22, 0)
		return
	end
	local veh = getPedOccupiedVehicle (playersource)
	setVehicleEngineState (veh, not getVehicleEngineState(veh))
	if getVehicleEngineState(veh) == true then
		triggerClientEvent (playersource, "displayClientInfo", playersource,"Vehicle","You started the Engine.",22,255,0)
	else
		triggerClientEvent (playersource, "displayClientInfo", playersource,"Vehicle","You stopped the Engine. ",255,22,0)
	end
end

 

[Mr.Loki]

replace line 2 with what i have then add an extra "end" under return
