save and load game data

[Happy_G]

im having trouble figuring out how to save and load game data like say saving what level someone is on as well as the number of lives they have and the items in thier posession and such, so just saving and loading specific variables or tables is what im trying to do

Something like this could work.

Code: Select all

function table.save( tab, filename )
	local f = love.filesystem.newFile( filename or "savedata.txt", love.file_write )
	love.filesystem.open( f )
	local data = ""
	for i, v in pairs( tab ) do
		data = data .. type(i) .. ";" .. i .. "=" .. type(v) .. ";" .. v .. "\n"
	end
	
	love.filesystem.write( f, data )
	love.filesystem.close( f )
end

function table.load( filename )
	if not love.filesystem.exists( filename or "savedata.txt" ) then return {}; end
	
	local tab = {}
	for line in love.filesystem.lines( filename or "savedata.txt" ) do
		local eqpos = (line:find( "=" ))
		
		
		local name = line:sub( 1, eqpos - 1 )
		
		local nbreakpos = (name:find( ";"))
		local nametype = name:sub( 1, nbreakpos - 1 )
		local namevalue = name:sub( nbreakpos + 1 )
		
		
		local data = line:sub( eqpos + 1 )
		
		local breakpos = (data:find( ";" ))
		local datatype = data:sub( 1, breakpos - 1 )
		local value = data:sub( breakpos + 1 )
		
		tab[_G["to" .. nametype]( namevalue )] = _G["to" .. datatype]( value )
	end
	
	return tab;
end
