[CanadianGamer]

Can Anyone help me I'm trying to make a game that saves both the settings and the Highscores.

There are a few libraries that can help you with that:

The method I use is a library to turn tables into JSON files and save that. You can open the file and then turn the JSON into a table and use it.

i wrote an easy method, just copy the table you need into file as lua script. the output is string, you can print it to test.

Code: Select all

function table.save(tab,name)
    name=name or "test"
    local output="local "..name.."=\n"
    local function ergodic(target,time)
        time=time+1
        output=output.."{\n"
        for k,v in pairs(target) do
            output=output .. string.rep("\t",time)
            if type(v)=="table" then
                if type(k)=="number" then
                    output=output.."["..k.."]".."="
                elseif type(k)=="string" then
                    output=output.."[\""..k.."\"]="
                end 
                ergodic(v,time)
                output=output .. string.rep("\t",time)
                output=output.."},\n"
            elseif type(v)=="string" then
                if type(k)=="number" then
                    output=output.."["..k.."]".."=\""..v.."\",\n"
                elseif type(k)=="string" then
                    output=output.."[\""..k.."\"]=\""..v.."\",\n"
                end 
            elseif type(v)=="number" then
                if type(k)=="number" then
                    output=output.."["..k.."]".."="..v..",\n"
                elseif type(k)=="string" then
                    output=output.."[\""..k.."\"]="..v..",\n"
                end 
            end
        end
    end
    ergodic(tab,0)
    output=output.."}\n return "..name
    return output 
end

Note that that method doesn't deal with cycles or some other types of data: strings containing ", nan, inf, keys that aren't strings or numbers, values that aren't tables, strings or numbers (like booleans), ...

There are plenty of good serialisation libraries available, I recommend using one of those (especially binser or one of my libraries: Ser, Lady or Smallfolk).

yeah, I forgot boolean. i still use binser or bintable in my own project. but this is an easy way to convert table to readable string.
