I think this is MTA bug but I wanna check first

[mtamaster97]

This is the whole code but idk why I get error

2 line = expected account at argument 1 got nil

4 line = expected element at argument 1 got nil

7 line = expected ped at argument 1 got nil

  
accName = getAccountName (account) -- get his account name 
me = getRootElement() 
account = getPlayerAccount(source) 
--local admin = isObjectInACLGroup ( "user."..getAccountName ( getPlayerAccount ( source ) ), aclGetGroup ( "Admin" ) ) 
mass = 100000 
veh = getPedOccupiedVehicle (ped) 
--local oldmass = getVehicleHandlingProperty ( element, "mass" ) 
  
function show(msg) 
    outputChatBox(msg,source, 0,81,255,true) 
end 
  
function turnOn(player, cmd, option) 
if option == "yes" then 
function babaking_tankYes ( me ) 
    if isObjectInACLGroup ("user."..accName, aclGetGroup ( "Admin" ) ) and veh then 
        bindKey ( me, "handbrake" or "space", "both", function(key,state) 
            if state == "down" then 
                setVehicleHandling ( veh, "mass", mass )  
                setVehicleHandling ( veh, "brakeDeceleration", mass )  
                show(tostring(getVehicleHandlingProperty ( element, "mass" ))) 
            elseif state == "up" then 
                setVehiceHandling (veh, "mass", true) 
                setVehicleHandling ( veh, "brakeDeceleration", true )  
                show(tostring(getVehicleHandlingProperty ( element, "mass" ))) 
            end 
        end) 
        addEventHandler ( "onResourceStart", getRootElement(), babaking_tankYes ) 
    elseif not veh then  
        return false 
    end 
end 
  
elseif option == "no" then 
    function babaking_tankNo ( me ) 
        if isObjectInACLGroup ("user."..accName, aclGetGroup ( "Admin" ) ) and veh then 
            bindKey ( me, "handbrake", "both", function(key,state)

Where is 'account' defined?

'getPlayerAccount(source)' 'source' is not defined or where else is it?

'getPedOccupiedVehicle(ped)' 'ped' is not defined or where else is it?

Nil means the variables you're referring to have nothing - they're nil, null, void, empty.

You will have to define the variables you use at the top of the script.

[mtamaster97]

ik whats nil lol, but aren't "source","thePlayer","player","ped" already defined at MTA Source codes?

thats the whole script there

I tryed this too but doesn't work

accName = getAccountName (source) -- get his account name 
source = getAccountPlayer(theAccount) 
account = getPlayerAccount(source) 
--local admin = isObjectInACLGroup ( "user."..getAccountName ( getPlayerAccount ( source ) ), aclGetGroup ( "Admin" ) ) 
mass = 100000 
veh = getPedOccupiedVehicle (ped) 
--local oldmass = getVehicleHandlingProperty ( element, "mass" ) 

any hint? which function should I use to define source ?

...I advise you to read the tutorials first.

[mtamaster97]

Man but atleast explain me what is wrong there? I don't see any mistake , i replaced source in 1,3 lines with "player" element and still don''t work I don't see any forking Idea why it shouldn't work

not logic man I made few small scripts and I'm not totally noob at scripting, but idk whats wrong with this.. just tell me if u know

Yes you are ! as you didn't understand that predefined variable like client and source are only available into functions that are handlers for events and that the value of source is different depending on the event it is handling.

You asked again to tell you what is wrong so here is your answer:

- You are trying to use undefined variables as arguments (source, theAccount and I can see ped aswell)

You are obviously not understanding what you are doing so read and follow the tutorials from the wiki first:

https://wiki.multitheftauto.com/wiki/Scr ... troduction

Here is a working example I could make from your code:

function changeMass(thePlayer, cmd, newMass) 
    local account = getPlayerAccount(thePlayer) -- get his account 
    local accName = getAccountName(account) -- get his account name 
    local isAdmin = isObjectInACLGroup("user."..accName, aclGetGroup("Admin")) 
    if isAdmin then 
        local veh = getPedOccupiedVehicle(thePlayer) 
        if veh then 
            local oldMass= getVehicleHandlingProperty (veh, "mass") 
            setVehicleHandling(veh, "mass", tonumber(newMass)) 
            outputChatBox("The mass of the car changed from "..oldMass.." to "..newMass..".", thePlayer, 0, 200, 0) 
        else 
            outputChatBox("You must be in a car first !", thePlayer, 200, 0, 0) 
        end 
    else 
        outputChatBox("You are not allowed to use this command !", thePlayer, 200, 0, 0) 
    end 
end 
addCommandHandler("changeMass", changeMass, false, false) 

Use /changeMass 20 to set the vehicle's mass to 20.
