file handling - Stuck with I/O operations in lua -

i'm trying design game in lua (this first game since i'm new language) okay.. have run score counter adds +1 on screen tap. want want save high score permanently.

i want display high score ('30' in case) separately on screen. , i'm stuck. tried tweaking i/o library, made things go more complicated. can help me please?

this have tried:

local f1 = io.open ("scoredata.txt", "a") function gameover() disp_tempscore() if score>highscore -- here initial value of highscore 0 highscore=score io.write (highscore) end score=0 -- turns score 0. (there separate score counter counts score , stores in 'score') mainscreen() local f2 = io.open ("scoredata.txt", "r") if f2~= nil save_high = io.read(highscore) end text_display2= display.newtext("best : " .. highscore, 0, 0, "helvetica", 90) text_display2.x = centerx text_display2.y = centery + 80 text_display2.alpha=1

now here score 'best :' appears highest score, multiple runs @ same time. mean when start game in corona simulator , play game 5 times (suppose), highest score shows right data. but, when exit simulator , restart it, highest score vanishes , displays 0. how can store info (score in case) permanently?

edit: (this had tried lastly (one of hits tried))

local function disapp (event) -- event listener responds "tap" local obj = event.target display.remove (obj) audio.play(sound) transition.cancel (event.target.trans) score=score+1 curr_scoredisp = score scoretext.text=score local f1 = io.open (path, "a") --writing score file if score>highscore -- initial value of highscore 0 highscore=score f1:write(highscore) end io.close(f1)

then :

local function disp_permscore() local f1 = io.open (path, "r") f1:read(highscore) text_display2= display.newtext("best : " .. highscore, 0, 0, "helvetica", 90) text_display2.x = centerx text_display2.y = centery + 80 text_display2.alpha=1 io.close(f1) end

this function reads score file , displays it. now? help in rectifying problem in way?

i think issue never write score file:

io.write (highscore)

should

f1:write(highscore)

and should close file no longer need (will prevent loss of info due crash, e.g.). don't forget utilize system.pathforfile( filename, system.documentsdirectory) described in corona docs, file set in right location.
