DataStore not working

Master1794 · April 12, 2021, 4:36pm

I am making a datastore that will save the players points and cash but it either says it can’t save or just nothing. I have tried just doing it for one value and the same problems happen. The player will get points by touching a part and cash by touching another part.

-- DataStore 
local DataStoreService = game:GetService("DataStoreService")

local playerData = DataStoreService:GetDataStore("PlayerDataStore")



local function onPlayerJoin(player)  -- Runs when players join

	local leaderstats = Instance.new("Folder")  --Sets up leaderstats folder

	leaderstats.Name = "leaderstats"

	leaderstats.Parent = player



	local cash = Instance.new("IntValue") --Sets up value for leaderstats

	cash.Name = "Cash"

	cash.Parent = leaderstats



	local points = Instance.new("IntValue") --Sets up value for leaderstats

	points.Name = "Points"

	points.Parent = leaderstats



	local playerUserId = "Player_" .. player.UserId  --Gets player ID

	local data = playerData:GetAsync(playerUserId)  --Checks if player has stored data

	if data then

		cash.Value = data['Cash']

		points.Value = data['Points']

	else

		-- Data store is working, but no current data for this player

		cash.Value = 0

		points.Value = 0

	end

end



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 onPlayerExit(player)  --Runs when players exit



	local player_stats = create_table(player)

	local success, err = pcall(function()

		local playerUserId = "Player_" .. player.UserId

		playerData:SetAsync(playerUserId, player_stats) --Saves player data

	end)



	if not success then

		warn('Could not save data!')

	end

end



game.Players.PlayerAdded:Connect(onPlayerJoin)

game.Players.PlayerRemoving:Connect(onPlayerExit)

-- Part script
local part = script.Parent

local canGet = true



local function onTouch(otherPart)

	local humanoid = otherPart.Parent:FindFirstChild('Humanoid')

	if humanoid then

		local player = game.Players:FindFirstChild(otherPart.Parent.Name)

		if player and canGet then

			canGet = false

			player.leaderstats.Points.Value = player.leaderstats.Points.Value + 1 

			wait(60)

			canGet = true

		end

	end

end



part.Touched:Connect(onTouch)

Use DataStore2 instead.

GoteeSign · April 12, 2021, 4:54pm

local data = playerData:GetAsync(playerUserId)  --Checks if player has stored data

	if data then

		cash.Value = data['Cash']

		points.Value = data['Points']

	else

Big mistake, because you have to put it in a pcall to make sure it works.

local data
local success, errormessage = pcall(function()
   data =  playerData:GetAsync(playerUserId)
end)
	if success then

		cash.Value = data['Cash']

		points.Value = data['Points']

	else

JackscarIitt · April 12, 2021, 5:03pm

Side note, but you should also check if the data is equal to a saved Number so that it doesn’t error as a nil value:

local data
local success, errormessage = pcall(function()
   data =  playerData:GetAsync(playerUserId)
end)
	if success and data then

		cash.Value = data['Cash']

		points.Value = data['Points']

	else

Just so you know, DataStores will not work in studio. Make sure you test in the actual game! (I’m not sure why it doesn’t)

legs_v · April 12, 2021, 5:32pm

They do work in studio? Are you slow lol? Its because the server sometimes closes before the player leaves causing it not to save!. Thats why you should use game:BindToClose(function() end)!

Cryptic_spike · April 12, 2021, 5:33pm

I know, however, I did not see :BindToClose() in his script and I did not want to complicate things! You are correct though.

Master1794 · April 12, 2021, 5:43pm

Does this go on line 78 in the original code which is:

local success, err = pcall(function()

		local playerUserId = "Player_" .. player.UserId

		playerData:SetAsync(playerUserId, player_stats) --Saves player data

	end)

I got no error but it didn’t work. I tried putting game:BindToClose(function() end) at the end but I don’t know if that is the correct place for it.

GoteeSign · April 12, 2021, 5:53pm

So it doesn’t save the data?

Master1794 · April 12, 2021, 5:53pm

Yeah it dosen’t save, no error or warning.

GoteeSign · April 12, 2021, 5:55pm

So is the create_table function creating a dictionary?

{
['Cash'] = {0};
['Points'] = {0}
}

GoteeSign · April 12, 2021, 5:57pm

Try doing this to make sure it makes a dictionary

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
print(create_table(player))

Put it inside of the onPlayerJoin function

Master1794 · April 12, 2021, 5:58pm

There is a leaderstats folder in player.Master1794 if thats what you mean.

GoteeSign · April 12, 2021, 5:59pm

Yeah, but when you run the create_table() function it needs to create a dictionary.
