How can I add a main menu to my game and variables that dont reset when closing the game?

I would like to add a main menu to my game with the buttons: play(execute game), options(easy mode, normal mode, hard mode and impossible mode(only availiable when highscore is higher than 100 in normal mode), credits(credits) and leaderboard(btw idk how to do the game online).

I would also like that the high-score didnt reset when closing the game.

Thanks

Also idk how to write in the game. I mean, the fist time you join the game you put your username and if its already been chosen then you have to put another username

No ones responding, so i will put in the credits the people who replies with a working code

Try looking at storage in the API docs for values that are remembered across game instances. To create an online game, check the networking docs.

Thanks, but I was asking for a code, i am new to microstudio. I dont really understand how to do an online ranking(btw i need a main menu for that)

I am in the right path? Mi code is the next:

serverInit = function()

worldrecord = 0

highscore2 = 0

highscore3 = 0

end

serverUpdate = function()

if highscore > highscore3 then

 if highscore > highscore2 then

   if highscore > wolrdrecord then

     worldrecord = highscore

   else

     highscore2 = highscore

   end

 else

   highscore3 = highscore

  end

end

end

Pls someone respond

init = function()
  a = 1
  b = 1000
  c = 1000000
end

update = function()
  a += 1
  b += 1
  c += 1
end

load = function()
  storage.get( "a", a )
  storage.get( "b", b )
  storage.get( "c", c )
end

save = function()
  storage.set( "a", a )
  storage.set( "b", b )
  storage.set( "c", c )
end

For a list of high scores sorted high to low, you can use something like this:

high_scores = []
MAX_SCORES = 3

add_score = function(score)
  high_scores.push(score)
  high_scores = high_scores.sort().reverse().slice(0, MAX_SCORES)
end

init = function()
  add_score(1)
  add_score(4)
  add_score(2)
  add_score(6)
  print(high_scores)
end

The code above will print [6, 4, 2] because there is a limit of 3 high scores.
