This function gives you various version information about MTA and the operating system.

Note: Clientside will return the version from the player, and the server-sided will return version from the server.


table getVersion (1.4 )

Required Arguments



Returns a table with version information. Specifically these keys are present in the table:

  • number: the MTA server or client version (depending where the function was called) in pure numerical form, e.g. "256"
  • mta: the MTA server or client version (depending where the function was called) in textual form, e.g. "1.0"
  • name: the full MTA product name, either "MTA:SA Server" or "MTA:SA Client".
  • netcode: the netcode version number.
  • os: returns the operating system on which the server or client is running
  • type: the type of build. can be:
    • "Nightly rX" - A nightly development build. X represents the nightly build revision.
    • "Custom" - A build compiled manually
    • "Release" - A build that is publicly released (provisional).
  • tag: the build tag (from 1.0.3 onwards). Contains infomation about the underlying version used. i.e. The final version of 1.0.3 has the build tag of "1.0.3 rc-9". (This can be confirmed by using the console command 'ver'.)
  • sortable: a 15 character sortable version string (from 1.0.4 onwards). Format of the string is described in getPlayerVersion.


Example 1: This example will make a script compatible only with version 1.0:

Click to collapse [-]
function setHoboSkin ( playerSource )
  local version = getVersion ( )
  if version.number < 256 then -- MTA 1.0 version number is 0x0100
    setPlayerSkin ( playerSource, 137 )
    setElementModel ( playerSource, 137 )
addCommandHandler ( "hobo", setHoboSkin )

Example 2: This client and server example will kick players that have anything earlier than the final released version of 1.0.3:

Click to collapse [-]
function sendVersion ()
  -- Send local player version to the server
  triggerServerEvent ( "onNotifyPlayerVersion", getResourceRootElement(), getVersion() )
addEventHandler ( "onClientResourceStart", getResourceRootElement(), sendVersion )
Click to collapse [-]
function handlePlayerVersion( version )
  if version.number > 256 + 3 then  -- Allow anything above 1.0.3
  if version.number == 256 + 3 then  -- Check further if it is exactly 1.0.3
    if version.type == "Release" then -- Check further if it is the "Release" type
      local _,_,buildnumber = string.find( version.tag or "", "(%d)$" )  -- Extract the build number if there
      buildnumber = tonumber(buildnumber) or 0
      if buildnumber >= 9 then  -- Allow 9 and above
  outputConsole( "Kicking player as below 1.0.3 Release build 9" );
  kickPlayer( client, "Upgrade your version at www.mtasa.com" )
addEvent ( "onNotifyPlayerVersion", true)
addEventHandler ( "onNotifyPlayerVersion", getResourceRootElement(), handlePlayerVersion )
