[SOLVED] Calling a function - nil error

FiveM Resource Development & Modding Discussion

Hi everyone,

I am trying to create a function that stops and starts an engine on demand, but somehow, I’m calling a function with a “nil” argument.

AddEventHandler("turnengine", function()
    Citizen.CreateThread(function()
	while true do
			local Ped = GetPlayerPed(-1)
			local lastCar = GetVehiclePedIsUsing(Ped)
			
		--    if (not car and lastCar == nil) then
		--       TriggerEvent("chatMessage", "ERROR", {255, 0, 0}, "You have to sit in a vehicle to set it as yours.")
		--    if (car) then
		--        lastCar = car
		--    end
			
			local engineStatus = GetIsVehicleEngineRunning(lastCar) -- the error occurs here
              
		--rest of the program below

Any help would be appreciated !

Can you send me whole script, so i can help you?

3

is the script client sided? If its server sided Citizen.CreateThread won’t work

4

The script is server sided. What would work then ?

Thanks !

5

Why would you need CreateThread anyways?
just remove it and it should work fine

6

It doesn’t, I still have an error :confused: Not the same though

Hi,

Here’s the complete client.lua

RegisterNetEvent("turnengine")


AddEventHandler('turnengine', function()
        local car = GetVehiclePedIsIn(GetPlayerPed(-1), false)
        
        engineStatus = GetIsVehicleEngineRunning(car)
        if engineStatus == 0 then
			SetVehicleUndriveable(car, false)
            SetVehicleEngineOn(car, true, false, true)
            TriggerEvent("chatMessage", "INFO", {255, 255, 0}, "Engine is now on.")
        elseif engineStatus == 1 then
            SetVehicleEngineOn(car, false, false, true)
            TriggerEvent("chatMessage", "INFO", {255, 255, 0}, "Engine is now off.")
			SetVehicleUndriveable(car, true)
        end
end)

I still have an error using GetIsVehicleEngineRunning.

Here’s the server.lua :

RegisterServerEvent("chatCommandEntered")

AddEventHandler('chatCommandEntered', function(p, color, msg)
    if msg:sub(1, 1) == "/" then
        fullcmd = stringSplit(msg, " ")
        cmd = fullcmd[1]
        
        if cmd == "/engine" then
            TriggerClientEvent("turnengine", p)
            CancelEvent()
        end
    end
end)

function stringSplit(self, delimiter)
  local a = self:Split(delimiter)
  local t = {}

  for i = 0, #a - 1 do
     table.insert(t, a[i])
  end

  return t
end

Thanks for your help
