DataStore2 does not work properly when using TeleportService

[ImKinaco]

1. What do you want to achieve? I would like to solve the problem in the title.

2. What is the issue? If I use TeleportService, it will lose all the progress you made on that server

3. What solutions have you tried so far? I tried every solution I could think of right away, such as delaying teleportation, saving player data before teleporting, etc.

Here is the Code that manages the data

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")
local ServerScriptService = game:GetService("ServerScriptService")

local DataStore2 = require(ServerScriptService.DataStore2)

Code that brings the player back to the lobby ((The data doesn’t behave properly after executing this Code.))

local TeS = game:GetService("TeleportService")
local Players = game:GetService("Players")

game.ReplicatedStorage.RemoteEvent.Exit.OnServerEvent:Connect(function(Player, UserID, PlaceID)

	pcall(function()
		local ServerScriptService = game:GetService("ServerScriptService")
		local DataStore2 = require(ServerScriptService.DataStore2)
		DataStore2:SaveAll(Player)
	end)

	wait(5)
	local Plr = Players:GetPlayerByUserId(UserID)
	TeS:Teleport(PlaceID, Plr)
end)

with the Roblox regular leave button, this problem does not occur at all

As you all know, DataStore2 saves every time a value changes, so why is data lost in the process of returning a player to the lobby?

This is strange, too, because sometimes it is saved well

Here’s a brief, one-way explanation.
This is a Tower Defense game, and when you finish defeating a boss, you get an Exit button (back to the lobby), and when you press it, all the XP and data you gained in that server will be lost, and you will be returned to the lobby.

I’ve tried everything I can try, and I’ve looked around on the Dev Forum, but I can’t find a satisfactory answer.

This is a problem I have been having for several months now. I posted this in the hope that i can find some clues.

Um, I am not seeing why your thing doesn’t save. My game is structured similar to TDS, but for racing, and I use a script like this:

local DataStore2 = require(game:GetService("ServerScriptService").DataStore2)
local CombinedDataStore = DataStore2.Combine("Currencies", "CurrenciesBackup")

local DefaultTable = {
	["Tires"] = 500,
	["Candy"] = 0,
	["Presents"] = 0,
	["Chocolate"] = 0,
}

game:GetService("Players").PlayerAdded:Connect(function(Player)
	local DataStore = DataStore2("Currencies", Player)

	local DataTable = DataStore:GetTable(DefaultTable)

	local Data = Instance.new("BinaryStringValue")
	Data.Name = "Currencies"
	Data.Parent = Player

	for DataType, Value in pairs(DataTable) do
		Data:SetAttribute(DataType, Value)
	end

	for DataType, Value in pairs(DefaultTable) do
		if not Data:GetAttribute(DataType) then
			Data:SetAttribute(DataType, Value)
		end
	end

	Data.AttributeChanged:Connect(function()
		local DataToSave = {}

		for Map, Value in pairs(Data:GetAttributes()) do
			DataToSave[Map] = Value
		end
		DataStore:Set(DataToSave)
	end)
end)

This saves just fine for me when teleporting back, and you can treat it like normal leader stats.

Two months have passed since then and the problem is still not solved.

The previous code had a lot of compassion for cheats, so I tried to change some things, but of course data is lost during teleportation.

I don’t have perfect knowledge of DataStore2 yet, and the code is still in the prototyping stage, so I’m assuming that the code is bloated in this way and that this problem is related to that. (Still, a lot of things don’t add up.)

I have the data separated by folder, do you not do that over there? (Separate by Currency, separate by tower, etc.)

[BillB1ox (Will)]

DataStore2 has a lot of issues related to multiplayer, that I am converting my live experience to ProfileService with a conversion process. Perhaps using ProfileService would be a much better option.

Also, ProfileService is a lot more versiltile, meaning that you can access data from the player even if they are offline.

[ImKinaco]

I see, I heard something very interesting.
is it possible to perfectly transfer the data already stored in DataStore2 to ProfileService?

[Juicy_Fruit]

I do believe the bloat is an issue, you make a seperate datastore for soooooo many things, tables do exist to eliminate this like you could theoretically just have local PlayerData = DataStore2(“PlayerData”, player) and then set up a huge table with all the entities

I can’t verify this but I believe the bloat could impact saving times, I also encountered this other issue and made a remark in a separate post:

I recall having a similar issue where I implemented ds2 with a game where mass teleporting was involved and there were issues with potential dataloss due to how ds2 saves (or atleast I believe it to be so) someone may buy an item and later teleport and a mass queue would result from teleporting with other players and it just could not save in time for the player to then join the teleported server with the same inventory etc. as when he joined the initial server lobby and when leaving it would save the old data instead.

you also say this:

This is a Tower Defense game, and when you finish defeating a boss, you get an Exit button (back to the lobby), and when you press it, all the XP and data you gained in that server will be lost, and you will be returned to the lobby.

Does the issue occur without the SaveAll functionality (I’m assuming thats why you decided to add it, to try and fix the issue)?, Ultimately you need to optimize into a singular table or something, and utilize saveasync (part of the ds2 api, I can provide sample code for ease) to check if data successfully saved, then send them off to the lobby

and as far as this goes @ImKinaco you should avoid be avoid physical objects and folders and you should be handling the information within scripts and while it is entirely up to you to do this and it may be past the point of return, its not a desirable habit, the more advanced you get in coding.

[ImKinaco]

There are many things that just don’t add up, and of course I am well aware that this bloated code needs to be fixed.

Why is this happening when the value is supposed to be saved each time it changes?

Why does it work perfectly when they press the Leave button on Roblox (the data is not saved when they press the button to return to the lobby provided by the game)?

And yes, the same problem occurs without SaveAll

Edit: Is there a way to read player data from other scripts without using physical values or folders? (e.g. what towers they own. or number of XP)

[Juicy_Fruit]

@ImKinaco

Why is this happening when the value is supposed to be saved each time it changes?

DS2 natively does not save until the player leaves, instead it has user data in a local cache to reduce significant getter requests. This cache is made upon the first get() which I assume is in a playeradded listening function you have.

again my ultimate solution here is:

1. Set up a singular table as your only datastore

2. Utilize saveasync() functionality when letting the player leave via your exit button (basically will make a success bool where if successful save then proceed to return to lobby else while loop until success with wait(1) to prevent infinite unhindered loop potential (which shouldn’t occur but always safe to yield)

Is there a way to read player data from other scripts without using physical values or folders?

Typically you would handle all variables within local variables of scripts, whenever you need to update them you would change them within the own script or communicate to other scripts the change.

It may be too much of a hassle for you at this stage to deal with I do not want to put this burden on you, but just to make you aware of a bad habit for later projects.

[ImKinaco]

That’s a very satisfying answer. Thank you so much.
And I should be a little more knowledgeable about data too.

If you don’t mind, may I take a look at the saveasync sample code you mentioned earlier?

[Juicy_Fruit]

How to use DataStore2 - Data Store caching and data loss prevention

How would I appropriately use SaveAsync() and determine if data sucessfully saved? This is my current snippet of sample code: InventoryStore:Set(Inv) local success, errorMessage = pcall(function() InventoryStore:SaveAsync() end) if not success then print(errorMessage) end

You would, in your case, make something like this:

local success, errorMessage = pcall(function()
	InventoryStore:SaveAsync()
end)
	if not success then
		print(errorMessage)
repeat
wait(1)
success, errorMessage = pcall(function()
	InventoryStore:SaveAsync()
end)
until success


	end

--let them leave after passing through the if block

something like this should work, just fix indentation and the datastore is a sample name.

I’ve also seen code where it has a number of retries before ultimately breaking the repeat loop or equivalent loop within setasync which is regular datastore functionality (both pretty much identical) its entirely your call. You might also consider breaking the loop if the player leaves during this. It is recommended @ImKinaco

[ImKinaco]

Please excuse my repeated attempts to contact you.

I have stored data where the original data (for example, boolean, num value and others) is quite complex, can I store it as one table and read data from it at any time without any problems?

The game is already in public beta and we want to improve it without losing the players’ data.

[Juicy_Fruit]

there would be no issues having an ultimate parent table holding the entities (you say they are complex but they are actually simple at least from reading the sample code provided and their associated table data)

--sample
PlayerData = {

Achievements={
--empty or not
},

XP=0,
--etc
}

One thing that came on my mind was if you wanted to convert or migrate peoples data, handle converting in the lobby so you don’t have to call combine on so many datastores within the main game area

[ImKinaco]

The problem has finally been resolved also the lag is much reduced. Thank you so much!
