Recommended way to read from and write to files?

[garcia1000]

Hello everyone, here's my current game!
https://dl.dropboxusercontent.com/u/218 ... eFrog.love

I would like to add a 'replay' function to my game. So basically, at the end of each round, it would save the entire keybuffer table for that round to a file. Then, I would have a 'replay' which would load the saved file, and then play it back.

Technically, the only part I don't know how to do is to read and write the file. I think the default love2d filesystem folder is in some crazy place where I need administrator privileges, and I don't know how to make it read/write from my base directory. What is a good way to do what I want to do here?

What leads you to believe that?

you may want to use an existing serialization library like Ser or serpent for example (there are tons and tons of these)

Thank you, I will try those and I'll come back if I can't get it to work.

I can't get this to work, what am I doing wrong?

I have this in conf.lua:

Code: Select all

function love.conf(t)
    t.identity = "files"
end

Then, I have this in main.lua:

Code: Select all

love.filesystem.write("files/Test.txt", "Hello", all)
love.filesystem.write("Test.txt", "Hello", all)

Neither of those writes "Hello" to Test.txt in the "files" folder.

I have also tried useing love.filesystem.setIdentity to set the path, but that doesn't work either.

If you want to write *all* data then:

Code: Select all

love.filesystem.write("Test.txt", "Hello")

P.S. "files" folder resides in the user's home directory like "home/<user's name>/.local/share/love/files" on Linux.

Thanks, that is my problem I think. I'm using a Windows machine and I think the 'home' directory needs administrator privileges to write, or something. I can't control how it acts on different machines.

Can I set the directory to be the same path where main.lua is?

Can I set the directory to be the same path where main.lua is?

How can you add a file in the archive (.love file)? It's nearly imposibble. If it can, how can you add a file on running file archive? So the answer is no. But if you're talking about another main.lua, which path are you talking about? Source base or save directory?

On windows the data is in APPDATA: https://www.love2d.org/wiki/love.filesystem (read the text at the beginning)

Ok, thanks, I see now!

I was trying to set a config.lua file in the same directory as main.lua. But that's impossible. Instead, it needs to create a config.lua file in the Appdata directory. Thanks.
