these are the variables at the start. theres nothing wrong cos it can display them in the game:

Code:

---

highscore = io.open("hiscore.txt","r")
theHighScore = highscore:read() --this is where it reads the file, it doesnt read it as a number
score = 0

Im not great with lua but you opened the file with an "r" tag? Wont that mean you can only read?

red = Color.new(255,0,0)
background = Image.load("cloud.png")
smiley = Image.load("smile.png")
sad = Image.load("sad.png")
math.randomseed(os.time())
rx = math.random(0,442)
ry = math.random(0,234)
highscore = io.open("hiscore.txt","r")
whighscore = io.open("hiscore.txt","w")
theHighScore = highscore:read()
boost = 2000
score = 0
x = 0
y = 5
TotalTimeLimit = 130

yes i have, it was 0 but i changed it to 10 and thats all thats there.

cmon help me!!!

The problem here is that when you read from a file, its reading it in as a string, not a number. Therefore you cannot compare a number with the string.

so how can i save a high score?

At the moment I am looking for a string to number/integer function in Lua (I really don't fancy writing one myself) but can't find any.

what do i write to make the whole thing restart? well?

Note that this code is for a standalone project only. You MUST press start to exit otherwise the file doesn't not get saved:

Code:

---

WHITE = Color.new(255, 255, 255)

highscore = io.open("hiscore.txt","r")
theHighScore = highscore:read("*number")
highscore:close()

currentScore = 0

while true do

    PspPadState = Controls.read();

    if PspPadState:start() then
            break;
        end
       
        if PspPadState:circle() then
            currentScore = currentScore + 1
        end

        screen:clear(WHITE)
        screen:print(1,1, "High Score    " .. theHighScore)
        screen:print(1,9, "Current Score " .. currentScore)
       
        screen.waitVblankStart();
        screen.flip();
end

if currentScore > theHighScore then
    highscore = io.open("hiscore.txt","w")
    highscore:write(currentScore)
    highscore:close()
end
