I need help please

[mint3d]

Ok so I made this script but every time the script restarts the power resets can anyone help me please?

mysql = exports.mysql 
  
function powerChange ( thePlayer, command, power ) 
    if exports.global:isPlayerLeadAdmin(thePlayer) then 
         
    power = tonumber ( power ) 
    local veh = getPedOccupiedVehicle ( thePlayer ) 
     
    if power and veh then 
        local success = setVehicleHandling ( veh, "engineAcceleration", power ) 
        if success then 
            outputChatBox ( "Your vehicle's acceleration has been changed to: "..power.." ", thePlayer, 0, 255, 0 ) 
            local dbid = getElementData(veh, "dbid") 
            mysql:query_free("UPDATE vehicles SET power="..power.." WHERE id="..dbid) 
            exports.logs:dbLog(thePlayer, 40, veh, "SETPOWER: "..power.."") 
        else  
            outputChatBox ( "Setting power failed.", thePlayer, 255, 0, 0 ) 
        end 
    elseif not veh then  
        outputChatBox ( "You're not in a vehicle.", thePlayer, 255, 0, 0 )  
    elseif not power then  
        outputChatBox ( "Syntax: /setpower [1 - 100000]", thePlayer, 255, 0, 0 )  
        end 
    end 
end 
addCommandHandler ( "setpower", powerChange )

Whenever you are using elementData, you must know that elementData is lost whenever the vehicle is destroyed (I mean, destroyElement, not blowVehicle). So that makes dbid get lost. So whenever you do a query, you'll have the wrong dbid.

What you should do then is to find the way to make some sort of vehicles system where the IDs are stored even after the server is shut down. That will probably do.

Whenever you are using elementData, you must know that elementData is lost whenever the vehicle is destroyed (I mean, destroyElement, not blowVehicle).

destroyElement, onVehicleExplode ( blowVehicle also triggers the function ) and restarting the source which spawned the vehicle destroys the vehicle. So it does also destroy the elementData.
