Question about Reading Data from a File

[NoreoAlles]

Hey, i know the thread beneath me is about a similar topic and i already asked something like this, but i just want to know, how i can read a save file with something like this in it:

Code: Select all

12, 30

and read it with the love.filesystem stuff so i could use it like this

Code: Select all

player.x, player,y = love.filesystem.read("SaveData")

Thanks

You can read data into 1 variable and parse it via lua's string library using pattern matching.
You can place every peace of data on new line and read it with https://love2d.org/wiki/love.filesystem.lines.
You might use some file format and users made library for that.
(In your case, it seems that CSV https://en.wikipedia.org/wiki/Comma-separated_values will suit you well;
quick google search show me https://github.com/geoffleyland/lua-csv as first lua CSV lib on github, so you might try it.)

Code: Select all

player.x, player.y = love.filesystem.read("SaveData"):match("(%d+).(%d+)")

The return is a string thus we can split it using matches.
It is also possible to read each number in the file but stop and go file reads can have a bad performance.

The tab separated values is better than comma separated values.

The tab separated values is better than comma separated values.

And why is that? It really does not matter as long as the input and the parser respect the same formatting rules. You can use any character for separating values such as pipe, semicolon, tabs etc. Completely up to you.
