[Solved] Save\Load without using libraries

[bramblez]

Hello, dear lovers :>

I've read few posts about load/save data, but I don't want to use any libraries. I have a .txt file with only 1 number and I am using filesystem to get that number for using in a table.

Code: Select all

file= love.filesystem.exists("1.txt")
	if not file == true then
		print("made 1.txt")

		data = love.filesystem.newFile("1.txt")
		data :open('w')
		data :write(1)
		data :close()
	end

	data = love.filesystem.newFile("1.txt")
	number = data :read()
	print(number) -- that works and prints '1' in console
	print(modes[number].width) -- that thing does not work, altho if you replace number with just a number '1' - it does work and prints other values from other table

is there a way to solve this somehow?

The example in the documentation says this:

Code: Select all

file = love.filesystem.newFile("data.txt")
file:open('r')
data = file:read()

The : open('r') call might be needed?

Although since it prints 1 you'd expect it to work as you posted it. Strange that it does not.

What time is it? Unsolicited code advice time!

Replace if not file == true then by if not file then, because the latter is much clearer.

You should actually open the file. In any case, it's because read returns a string.

Well thank you, kindly :>

I've tried

Code: Select all

	   data = love.filesystem.newFile("1.txt")
   number = data :open('r') --also tried open('w')
   print(number) -- that works and prints '1' in console
   print(modes[number].width) -- does not work

but no luck. Is there a way to get a value from this file not as a string?

yesterday there was a similar thread about that.

Well, you changed nothing, try using number = tonumber(file:read()).
And yes, it should be file:read, after file:open.
