Simple way to keep track of a high score with corona sdk [closed]

问题

I have nearly finished my game (just graphics and this to do) but do not know how I can save high scores. I searched corona's apis but did not manage to find what I needed. I also downloaded this http://techority.com/2011/12/28/ego-easy-saving-and-loading-in-your-corona-apps/ but it kept saving the wrong high scores...

Any ideas on the best and simplest way to do this will be greatly appreciated,

thanks in advance.

I use the following to save highscores attached to my game. It is not EXACTLY the solution you want but you should be able to modify this for your needs.

I declare a global variable called highscore that keeps track of all the scores. Since I have a level selection screen and highscore screen I have decided to declare these in my menu so I can have them loaded and available before navigating the game.

I can then get each individual highscore for each level by simply calling Highscores[levelNumber]. When I want to change the highscore I simply call Highscores[1] = 500 and remember to call saveHighscores()

Put the following into your main

local highscoreHandler = require("highscoreHandler")

highscores = 
{   
0, 0, 0, 0, 0
}

highscores = loadHighscores()

And put this into a seperate file called highscoreHandler.lua

local json = require "json"

function loadHighscores()
    local base = system.pathForFile( "highscores.json", system.DocumentsDirectory)
    local jsoncontents = ""
    local highscoresArray = {}
    local file = io.open( base, "r" )
      if file then
        local jsoncontents = file:read( "*a" )
        highscoresArray = json.decode(jsoncontents);
        io.close( file ) 
        return highscoresArray
        end
     return highscores
  end

function saveHighscores()
      local base = system.pathForFile( "highscores.json", system.DocumentsDirectory)
      local file = io.open(base, "w")
      local jsoncontents = json.encode(highscores)
      file:write( jsoncontents )
    io.close( file )
  end
