How to Reliably Save with Datastores?

Hi Noobe,

My data storage always works with the player leaving but, it was having issues with just one player being in the game and leaving. Which I found a simple solution for, and this is using the game's :BindToClose() method.

So, if a player leaves and there's other players in the server then the server doesn't shut down, in which case it's pretty simple to save the data right away by just storing it in a table or dictionary.

####This is just an example from the game that I'm working on right now, but here it is:

function save_data(plr)
	local stats = plr:WaitForChild("Stats");
	local tab_to_save, key = {}, "user-"..plr.UserId;
	
	for _, stat in next, stats:GetChildren() do
		tab_to_save[stat.Name] = stat.Value;
	end
	
	pcall(function()
		ds:SetAsync(key, tab_to_save);
	end)
	
end

###However, this gets somewhat complicated when the server shuts down and there isn't enough time for the game to save the data. In this case, I use the game's :BindToClose() method to have a callback function save the data right away as the server is shutting down.

####This is also an example from the game that I'm working on right now:

function player_removing(plr)
	
	wait(0.001);
	
	if not is_closing_game then
		save_data(plr)
	end
end

game:BindToClose(function()
	is_closing_game = true;
	
	for _, plr in next, plrs:GetPlayers() do
		save_data(plr);	
	end
end)

###The reason I wait for 0.001 seconds in the player_removing function is so that is_closing_game can update if the game is closing. So, the player_removing function doesn't try to save the data because the callback function in :BindToClose() is already on it.

##Hope I helped and have a wonderful day/night.

Thanks,
