You need to use the I/O library to save a file that contains the save information. I used this in Skydiver 3.0. Here is the code:

Save highscore:

Code:

highscorefile = assert(io.open("highscores", "r"))

currentScore = highscorefile:read("*line")

highscorefile:close()



position_of_slash = string.find( currentScore, "/" )

score = tonumber( string.sub( currentScore, position_of_slash + 1, string.len( currentScore ) ) )



if level > score then

BGTopText:PrintXY( 1, 1, "Congratulations!" )

BGTopText:PrintXY( 1, 2, "You have the best score!" )

BGTopText:PrintXY( 1, 4, "Type your name please." )

require( "keyboard.inc.lua" )

name = keyboard( 20 )

writetoscorefile = name .. "/" .. level

highscoresfile = assert(io.open("highscores", "w"))

highscoresfile:write( writetoscorefile )

highscoresfile:close()

end

Load highscore:

Code:

function highScores()

Screen.Initialize( SCREEN_BOTTOM, BGBotText, BGBotBackground )



highscorefile = assert(io.open("highscores", "r"))

score = highscorefile:read("*line")

highscorefile:close()



position_of_slash = string.find( score, "/" )

name = string.sub( score, 1, position_of_slash - 1 )

score = string.sub( score, position_of_slash + 1, string.len( score ) )



-- Print out name and score

BGBotText:PrintXY( 1, 1, name .. " - " .. score .. " points" )



BGBotText:PrintXY( 1, 14, "Press A to go back." )



while Pads.A() == false do

end



styluswasinX = Stylus.X()

styluswasinY = Stylus.Y()

end

thanks i test it

Also, it would be a good idea to make some encryption on the file to prevent people from cheating.

Yes, but encryption would:

- Be difficult.
- Slow down the saving and loading times.
- Involve some sort of annoying string.gsub technique.
- Suck.

Not really... If you make your own encryption/decryption algo it won't be.
