#67

Hello alex i tried your script it does save but it does not load my old data , any reason?
old script as indicator

local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("DataSaver001")
local Players = game:GetService("Players")

game.Players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player

	local Money = Instance.new("IntValue")
	Money.Name = "Money"
	Money.Parent = leaderstats

	local success, data = pcall(function()
		return DataStore:GetAsync(player.UserId.."-Money")
	end)

	if success then
		Money.Value = data or 3000
		print(player.Name .. " has " .. Money.Value .. " money.")
	else
		warn("Error while loading Money data: " .. data)
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	local success, error = pcall(function()
		DataStore:SetAsync(player.UserId.."-Money", player.leaderstats.Money.Value)
		print(player.Name .. "'s money data saved. Current money: " .. player.leaderstats.Money.Value)
	end)

	if success then
		print("Player data saved successfully!")
	else
		warn("Error while saving Money data: " .. error)
	end
end)

current script ( problem )

local DataStoreService = game:GetService("DataStoreService")
local oldDataStore = DataStoreService:GetDataStore("DataSaver001")
local newDataStore = require(script.DataStore2)
newDataStore.Combine("DATA2", "player") -- better do not change DATA2 for testing only

local function create_table(player)
	local player_stats = {}
	for _, stat in pairs(player.leaderstats:GetChildren()) do
		player_stats[stat.Name] = stat.Value
	end
	return player_stats
end

local function onPlayerJoin(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player

	local money = Instance.new("IntValue")
	money.Name = "Money"
	money.Parent = leaderstats

	local MoneyStats = newDataStore("DATA2", player)
	local data = MoneyStats:Get(player.UserId.."-Money")
	if not data then 
		local success, oldData = pcall(function()
			return oldDataStore:GetAsync(player.UserId.."-Money")
		end)
		if success then
			data = oldData or {Money=3000} 
			MoneyStats:Set(player.UserId.."-Money", data)
		else
			warn("Error stupewddd " .. oldData)
			data = {Money=3000} 
		end
	end

	money.Value = data['Money']

	money.Changed:Connect(function(value)
		MoneyStats:Set(player.UserId.."-Money", create_table(player))
	end)
end

local function onPlayerExit(player)
	local player_stats = create_table(player)
	local MoneyStats = newDataStore("DATA2", player)
	local success, err = pcall(function()
		MoneyStats:Set(player_stats)
		MoneyStats:Save()
	end)

	if not success then
		warn('Game problem lol')
	end
end

let me know

#68 
local data = MoneyStats:Get()

You don’t need to use the key as this is already the player’s base (local MoneyStats = newDataStore("DATA2", player))

And also here, do not use the key, only the values

MoneyStats:Set(data)

ouh i see my bad , lack of knowledge … i will try that

Hey alex thank you for the info
My database finally done and it works well , but im not 100% sure it will save since im still new with datastore2 , what can i add or change to make it better ?

Hey alex! thanks a lot, I was able to do the cars one but I have a little problem with the money and Delivers one because it works but when the player saves something, it doesn’t really save anything and it only keeps the DS1 information.

#73

How exactly does it not save? Everything worked before…

#74

Hey dude , script runs well but whenever alot of player join at the same time , warning added to queue or data sent too frequently occur . How do i counter this?

My idea to counter = add gap between each player to let them load data and save data ( save data needed since if data not loaded yet and saved occur , need to wait data loaded first before data save ) .

#75

Well this shouldn’t be a problem since the limit is 60+10*n and there are 10 extra requests per player, maybe you’re doing too fast or too much saving or getting data somewhere

#77

its runs fine , but when alot of player join at the same time warning occur , like its really weird . if normal datastore script it doesnt give me kind of warning

#78

there is a plugin named datastore editor

#79

How many can join the server as much as possible?

#80

20 player max but old one 17 player max , should i lower to 12 or 15 ? AND btw sometime data not load perfectly sometime it print nil instead of their money

I think main problem is i call async money and cars at the same time , i would like to add delay but im scared if game updated and player got no enough time load their second data which ended up dataloss due failed to load and save second data

#81

It happens that yes, it shows the information stored in the DB1 but I think that as the info loaded in the DS2 is directly from the DS1 it is not updated but remains static.
