[illestiraqi]

This script turns the vehicle engine off by pressing F to turn on/off. Pressing L will toggle the lights on/off. this is not made by me just a notice! Anyways I want the "F" button changed to /engine to turn vehicle on/off please help.

function engineOffOn(source) 
    if isPedInVehicle(source) then 
        local sourceVehicle = getPedOccupiedVehicle( source ) 
        if getVehicleEngineState ( sourceVehicle ) then 
            setVehicleEngineState ( sourceVehicle, false ) 
        else 
            setVehicleEngineState ( sourceVehicle, true ) 
        end 
    end 
end 
  
function changeLightsState(source) 
    if isPedInVehicle(source) then 
        local sourceVehicle = getPedOccupiedVehicle( player ) 
        if getVehicleOverrideLights ( sourceVehicle ) ~= 2 then 
            setVehicleOverrideLights( sourceVehicle, 2 ) 
        else 
            setVehicleOverrideLights( sourceVehicle, 1 ) 
        end 
    end 
end 
  
addEventHandler ( "onPlayerVehicleEnter",root,function( theVehicle, driver, jackerPlayer ) 
    -- if it's the driver who got out, and he was not jacked, 
    if driver == 0 and not jackerPlayer then 
        -- turn on the engine 
        setVehicleEngineState ( theVehicle, true ) 
    end 
end) 
addEventHandler ( "onPlayerVehicleExit",root,function( theVehicle, driver, jackerPlayer ) 
    -- if it's the driver who got out, and he was not jacked, 
    if driver == 0 and not jackerPlayer then 
        -- turn off the engine 
        setVehicleEngineState ( theVehicle, false ) 
        setVehicleOverrideLights ( theVehicle, 1 ) 
    end 
end) 
  
addEventHandler ( "onResourceStart",resourceRoot,function() 
    if res~= getThisResource() then return end 
    local engineKey = get("@jengine.engineKey") 
    local lightsKey = get("@jengine.lightsKey") 
    for _, player in ipairs(getElementsByType("player")) do 
        bindKey (player, engineKey, "down", engineOffOn ) 
        bindKey(player,lightsKey, "down", changeLightsState ) 
    end 
end) 
addEventHandler("onResourceStop",resourceRoot,function(res) 
    if res~= getThisResource() then return end 
    for _, player in ipairs(getElementsByType("player")) do 
        unbindKey (player, engineKey, "down", engineOffOn ) 
        unbindKey(player,lightsKey, "down", changeLightsState ) 
    end 
end)

    bindKey(source,lightsKey, "down", changeLightsState) 
end) 
addEventHandler ( "onPlayerQuit",root,function() 
    unbindKey (source,engineKey, "down", engineOffOn) 
    unbindKey(source,lightsKey, "down", changeLightsState) 
end)
