hey guys  sorry for being a bug but i am having trouble saving my high score.  my high score like this

highscore = 0 score =0 local function save( event ) -- function to save score local path = system.pathForFile( "score.txt", system.DocumentsDirectory ) -- where the file will be saved local file = io.open( path, "w+b" ) -- opening the file file:write(highscore.."") -- writing the variable 'score' in the score.txt file io.close( file ) -- closing the file -- Saves our data end local function resumeStart() local path = system.pathForFile( "score.txt", system.DocumentsDirectory ) -- where the file will be saved local file = io.open( path, "r" ) -- opens the file under the variable file if file then -- if there is a file then local contents = file:read( "\*a" ) -- read the contents of the file, and read the whole string(\*a) local prevState = explode(", ", contents) -- put the contents of score.txt into a table print('file') highscore = prevState[1] -- read the table at position 1 and assign the variable score io.close( file ) -- close file else -- if there is no file highscore=0 -- the score then starts at 0 end end --ANSCA sample code-- function explode(div,str) if (div=='') then return false end local pos,arr = 0,{} -- for each divider found for st,sp in function() return string.find(str,div,pos,true) end do table.insert(arr,string.sub(str,pos,st-1)) -- Attach chars left of current divider pos = sp + 1 -- Jump past current divider end table.insert(arr,string.sub(str,pos)) -- Attach chars right of last divider return arr end --ANSCA sample code^-- resumeStart() -- call the starting function function scoreUpdate(event) score = score +100 scoreText.text = ""..score ---scoreText:setTextColor(225,225,225) --scoreText:setReferencePoint(display.TopLeftReferencePoint) scoreText.x = 150 scoreText.y = 40 if highscore \< score then print "highscore" highscore = highscore +100 highscoreText.text = ""..highscore --scores:increment( "player2") --scores:save() save() end end

the problem is i want to compare two value  the high score and score it self like this

if highscore \< score then print "highscore" highscore = highscore +100 highscoreText.text = ""..highscore save() end &nbsp;

 but i keep getting this error  “attempt to compare string with number” 

also could  i just use Apple or google leaderboard system to save my high scores? i am very lost on this please help. 

i even try using ice box  but no luck :frowning:

thanks

Your post is nearly impossible to read.  Can you please use the code tags located in the toolbar, they look like this <>

#3

Our library may help you - https://github.com/GlitchGames/GGScore

#4

i fix the code could someone help please 

#5

Your code still looks hard to read, I didn’t even bother. I suggest you use GGScore from the guys at Glitch Games or the ICE library file, they are far simpler to use than what you are trying to do yourself

#6

okay but how do i use GGscores because i don’t understand it. ice box make my game  lag so i don’t use it thanks :)

 is this better :slight_smile:

Yes it is, but I would still advise using one of the libraries I mentioned above. They do all this for you and there is some examples of implementation. It makes life a lot easier

#10

It’s slightly more readable however proper indentation goes a very long way.

If you didn’t like Ice then you might prefer GGData, it’s our updated and much improved version.

#11

I use ice myself

#12

my problem is how would i use gg data or even ice box  to save this 

 function scoreUpdate(event)

 score = score +100 

 scoreText.text = “”…score

—scoreText:setTextColor(225,225,225)

 --scoreText:setReferencePoint(display.TopLeftReferencePoint)

 scoreText.x = 150

 scoreText.y = 40

if highscore < score then 

 print “highscore”

highscore = highscore + 100 

highscoreText.text = “”…highscore 

  

end 

end

i am having a real hard time trying to save the high score in my games
