   You can't. There's currently no Lua functions that I know of relating to save / load game.
   
   Why do you want to use Lua for this? If you are wanting to create an automated autosave system then sure you can use Lua script to a degree for checking when it should save the game, but you will still need to create a called by other action which contains an execute autosave action part.
   
   How I sorted out my autosave system was to create a loop in Lua script using the mainLoop event handler, then inside the loop function I listen out for two things...
   
   1. scene change & 2. scene is not a menu. I update a variable with new scene if it doesn't equal the last scene & if it's not a menu then I call the called by other action containing the autosave actions.
   
   

   -- * variables * --
   local ps -- empty variable(s)
   
   -- * function used to check if game should autosave (saves on new scene [playable]) * --
   function autosaveSystem()
    if game.CurrentScene:getName() ~= ps then
     ps = game.CurrentScene:getName() -- update scene name
     if not game.CurrentScene:getBool(VSceneIsMenu) and not game.CurrentScene:isEmpty() then 
      startAction("Actions[autosave_system]")
     end
    end
   end
   
   registerEventHandler("mainLoop", "autosaveSystem") -- creates a loop function which loops autosaveSystem() function

   I have a global key handler which watches for the Back Key (Android), so i wanted to create a save point before going to the menu.
   I'll create an action and call that then, thanks.
