LÖVE

Is there a way of saving and loading files from anywhere? Like "C:\users\darlex\Desktop\project1" or "\home\darlex\desktop\project1"?
Im trying to do a game editor thing but i dont know how to do that :/

I'd suggest the IO library: https://www.lua.org/pil/21.2.2.html

Not easily; löve by default doesn't support that (with the exception of dragging folders and files), but there are a few solutions;
You can either use an external lib like luafilesystem and sacrifice it working with any constructors löve gives you (since they still depend on PhysFS that love.filesystem uses), or you can use my library that for now, allows loading from anywhere: love-fml on github. (and yes, my lib can take care of OS-specific differences in a neat way, so you don't have to worry about that)

As posted before, you could always do the following.

"C:\" is a Windows thing and it won't work across platforms.
You want your game to work on any device, right?

Just save the maps to the appData folder and you should be fine.

Im trying to do a game/map editor and the fact of saving everything in the appdata thing is tedious.
I want to give that sensation of comfort of saving and loading files from anywhere to anywhere.
Like tilesheets, lua files and etcetera

Code: Select all

-- ***** Load/Save from Anywhere on Computer *****
-- To use, wrap 'filename' with 'mount'.
-- 				for  filename =  'D:/Scripts/Love/test.png'
-- Load Example:			love.graphics.newImage( mount( filename ) )
-- Save Example:			id:encode('png', mount( filename ) )
-- 				for dir = 'D:/Scripts/Love'
-- Files in Directory:	files = love.filesystem.getDirectoryItems( mount( dir ) )
--	Create Directory:	love.filesystem.createDirectory( mount( savedir ) )

mount = function( name )
	local ffi = require( 'ffi' )
	local lv		= ffi.load( 'love' )
	ffi.cdef[[ int PHYSFS_mount(const char *newDir, const char *mountPoint, int appendToPath); ]];
	ffi.cdef[[ int PHYSFS_setWriteDir(const char *newDir); ]]
	local file	= name:match( "^.+/(.+)$" )			-- filename
	local path	= string.sub( name, 1, -(#file+1) )	-- path without filename
	lv.PHYSFS_setWriteDir( path )
	lv.PHYSFS_mount( path, nil, 0 )
	return file
	end

Wow, that's useful! Thanks!
But... Does work with unix-like systems? ("/home/darlex/desktop/project1/")

Frankly speaking, I don't see anything "comfortable" in dealing with file dialogs, etc.
In fact, most modern programs never ask you to browse around the device's filesystem.
A good example would be apps on Android and iOS.

Beauty in the eye of the beholder, i guess; frankly, i'd rather know how to navigate the cesspool of a filesystem that modern OS-es have than just blindly rely on apps telling me where they put my files.

As the "Usage" part says on github, you really only need to do require('fml')() if you put the files next to your main.lua; after that, you can use syntax like "drv/c/Program Files/..." for windows or "drv/usr/..." for Linux and similar for OSX to refer to any file on your filesystem... and you can still use "src/..." or "usr/..." for the source or save directories, respectively.
