In need of a Save Instance replacement, anyone got one?

Hey Cuvette,

You can indeed save the house data to DataStore by way of SetAsync and UpdateAsync, both methods of GlobalDataStore. The Wiki page:

http://wiki.roblox.com/index.php?title=API:Class/GlobalDataStore

Keep in mind, you cannot save instances to a GlobalDataStore. You can, however, get away with saving a tables like this to DataStore:

local position = part.Position;

{
	Position		= {
		x = position.x;
		y = position.y;
		z = position.z;
	};

	BrickColor	= part.BrickColor.Name;
	-- ...
};

Rinse and repeat for each part in the house and save each entry in a list. Publish the list using DataStore, and get it back using GetAsync. When you retrieve the list, iterate over it and use a function like this to render each entry:

local function ConvertEntry(entry)
	local part		= Instance.new("Part", path.To.Parent);
	local position	= entry.Position;

	part.BrickColor		= BrickColor.new(entry.BrickColor);
	part.Position		= Vector3.new(position.x, position.y, position.z);
end;

There are other ways you might achieve this. If your house behaves more like a tycoon, you might make an entry for each available upgrade:

-- If an item is true, it's been unlocked, and vice versa.
{
	Walls		= true;
	Roof			= true;
	KitchenSink	= false;

	-- And so on.
};

Again, you'd iterate over this table and render the respective prefabricated upgrades depending on their respective upgrade values.

I highly recommend checking out the following Wiki pages to learn more:

Have a nice day, Cuvette, and best of luck with your game!
