I do this in my loader script. (Disclaimer: I’m learning this myself, so it might not be the best way. And sorry for the formatting. I’m writing this, commuting on a train. :slight_smile: )

Flow is something like this;

  • Gamedata is stored in a module. At the moment it only contains a table for player, storing the highscore and current score.

  • Loader loads saved data into this table, and stores table at given moment (in my case overtime player returns to main menu) Code snippets:

shared_data.module:

local M = {
  player = {
    highscore = 0,
    score = 0
  }
}
return M

loader.script:

    local shared_data = require "main/modules/shared_data"
    local save_file = sys.get_save_file("my_game", "gamedata")

function save_gamedata(self)
	-- Reset player score
	shared_data.player.score = 0
	-- Save gamedata
	if not sys.save(save_file, shared_data) then
		pprint("Gamedata not saved.")
	end
end

function load_gamedata(self)
	--	Load gamedata
	local gamedata = sys.load(save_file)
	if not next(gamedata)  then
		pprint("Gamedata empty")
	else
		pprint(gamedata)
		shared_data.player.highscore = gamedata.player.highscore
	end
end

function init(self)
	msg.post(".", "acquire_input_focus")
	load_gamedata(self)
	load_menu(self)
end

function on_message(self, message_id, message, sender)
   ...
   elseif message_id == hash("back_to_menu") then
    	unload_main(self)
    	load_menu(self)
    	save_gamedata(self)
    elseif ...
    end 
end
