Need help; unlocking vehicle outside it, turn signals

[Play3rPL]

Hello!

Thanks for coming here. First at all, let me say that my English is not perfect, so it can be bad sometimes.

Okay. I am asking You for help with two things:

1#: Unlocking locked vehicle outside it.

Look: I made my own script for my RPG server; it allows You to enable lights using ; key, engine using K, enable Freeze-aka-handbrake using RCTRL, and lock vehicle using L key. Only driver can perform these things.

So, there is my question:

When car is locked, and You will exit that, You cannot unlock it anymore. I want to make script, that will allow You to unlock it, when ped is standing next to driver's doors using L key again. How can I script that?

I have been thinking of making an INVISIBLE marker, next to driver's door. When ped will stay at it, he is able to unlock it using L key.

Marker could be done by taking vehicle's x, y, z, and adding some numbers to x/y. But how can I do it invisible? VisibleTo function, or anything else? And how Can I cause unlock by using L?

2#: Turn signals.

It's kinda important thing for RPG servers. Actually, I have no clue about making them. Using SetLightState probably, but I'm do not understand the use of them.

--------------------------------

I am NOT asking for ready code; I'm asking for help and some clues about doing these things.

Here's my actual code. I'm going to show it also to prove, that I actually did something:

-------------------------------------- KONTROLKI - 8.0 
  
local root = getRootElement () 
local thisResourceRoot = getResourceRootElement(getThisResource()) 
  
function thisResourceStart () 
    local players = getElementsByType ( "player" ) 
    for k,v in ipairs(players) do 
        bindKey ( v, ";", "down", toggleVehicleLights, "Lights on/off" ) 
                bindKey ( v, "k", "down", toggleVehicleEngine, "Engine on/off" ) 
                bindKey ( v, "rctrl", "down", toggleVehicleHandbrake, "Handbrake on/off") 
                bindKey ( v, "l", "down", toggleVehicleLock, "Doors locked/unlocked") 
    end 
end 
  
  
  
function playerJoin () 
        bindKey ( v, ";", "down", toggleVehicleLights, "Lights on/off" ) 
                bindKey ( v, "k", "down", toggleVehicleEngine, "Engine on/off" ) 
                bindKey ( v, "rctrl", "down", toggleVehicleHandbrake, "Handbrake on/off") 
                bindKey ( v, "l", "down", toggleVehicleLock, "Doors locked/unlocked") 
end 
  
addEventHandler ( "onResourceStart", thisResourceRoot, thisResourceStart ) 
addEventHandler ( "onPlayerJoin", root, playerJoin ) 
-- Lampy 
function toggleVehicleLights ( player, key, state ) 
    if ( getPedOccupiedVehicleSeat ( player ) == 0 ) then 
        local veh = getPedOccupiedVehicle ( player ) 
        if ( getVehicleOverrideLights ( veh ) ~= 2 ) then 
            setVehicleOverrideLights ( veh, 2 ) 
            outputChatBox ( "Światła Włączone!", player, 0, 255, 0 ) 
        else 
            setVehicleOverrideLights ( veh, 1 ) 
            outputChatBox ( "Światła Wyłączone!", player, 255, 0, 0 ) 
        end 
    end 
end 
-- Silnik 
function toggleVehicleEngine ( player, key, state ) 
    if ( getPedOccupiedVehicleSeat ( player ) == 0 ) then 
        local veh = getPedOccupiedVehicle ( player ) 
        if ( getVehicleEngineState ( veh ) == true ) then 
            setVehicleEngineState ( veh, false ) 
                        outputChatBox ( "Silnik Wyłączony!", player, 255, 0, 0 ) 
        else 
            setVehicleEngineState ( veh, true ) 
                        outputChatBox ( "Silnik Włączony!", player, 0, 255, 0 ) 
        end 
    end 
end 
-- Ręczny 
function toggleVehicleHandbrake ( player, key, state ) 
    if ( getPedOccupiedVehicleSeat ( player ) == 0 ) then 
        local veh = getPedOccupiedVehicle ( player ) 
                local speed = getElementVelocity ( veh ) 
                if ( speed == 0 ) then 
                        if ( isElementFrozen ( veh ) == false ) then 
                                setElementFrozen ( veh, true ) 
                                outputChatBox ( "Ręczny Zaciągnięty!", player, 255, 0, 0 ) 
                        else 
                                setElementFrozen ( veh, false ) 
                                outputChatBox ( "Ręczny Spuszczony!", player, 0, 255, 0 ) 
                        end 
                else 
                        setControlState( player, handbrake, true) 
                end                     
    end 
end 
-- Zamek 
function toggleVehicleLock ( player, key, state ) 
    if ( getPedOccupiedVehicleSeat ( player ) == 0 ) then 
        local veh = getPedOccupiedVehicle ( player ) 
        if ( isVehicleLocked( veh ) == false ) then 
            setVehicleLocked ( veh, true ) 
                        outputChatBox ( "Pojazd Zamknięty!", player, 255, 0, 0 ) 
        else 
            setVehicleLocked ( veh, false ) 
                        outputChatBox ( "Pojazd Otwarty!", player, 0, 255, 0 ) 
        end 
    end 
end 

I'm sorry for Polish chat outputs and --s; script is done one hundred % by me.

Thanks, again, for any help!

Cheers,

idk if its works the marker make it visible and try to find where is close to door

function toggleVehicleLock(thePlayer, key, state) 
    if (getPedOccupiedVehicleSeat(thePlayer)== 0) then 
        local veh = getPedOccupiedVehicle(thePlayer) 
        if isVehicleLocked(veh) == false then 
           setVehicleLocked(veh, true) 
        else 
           setVehicleLocked(veh, false) 
        end 
        local x, y, z = getElementPosition(veh) 
        local marker = createMarker(x+5, y, z, "cylinder", 1, 255, 0, 0, 0) 
    end 
end 
        addEventHandler("onMarkerHit", getRootElement(), 
           function() 
               if isPedInVehicle(thePlayer) == false then 
                  if isVehicleLocked(veh, true) and state == "down" then 
                     setVehicleLocked(veh, false) 
                  end 
               end 
            end)
