Problem with datastore

MRBOGO_YT · January 26, 2022, 7:12pm

What do you want to achieve? Keep it simple and clear!
I want to save the players money, xp, and level.
What is the issue? Include screenshots / videos if possible!
It won’t save. It always comes up with this error;
13:10:21.510 Unable to cast value to Object - Server - leaderstats:49

My code;

local DSS = game:GetService("DataStoreService")
local MDS = DSS:GetDataStore("myDataStore")

game.Players.PlayerAdded:Connect(function(plr)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = plr
	
	local EP = Instance.new("IntValue")
	EP.Name = "Evolution Points"
	EP.Parent = leaderstats
	
	local XP = Instance.new("IntValue")
	XP.Name = "XP"
	XP.Parent = leaderstats
	
	local Level = Instance.new("IntValue")
	Level.Name = "Level"
	Level.Parent = leaderstats
	
	local data
	local data2
	local data3
	local success, errormessage = pcall(function()
		data = MDS:GetAsync(plr.UserId.."-Evolution Points")
		data2 = MDS:GetAsync(plr.UserId.."-XP")
		data3 = MDS:GetAsync(plr.UserId.."-Level")
	end)
	
	if success then
		EP.Value = data
		XP.Value = data2
		Level.Value = data3
	else
		print("Failed!")
		warn(errormessage)
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	local success, errormessage = pcall(function()
		MDS:SetAsync("id_"..plr.UserId, plr.leaderstats["Evolution Points"].Value, plr.leaderstats.XP.Value, plr.leaderstats.Level.Value)
	end)
	
	if success then
		print("Success!")
	else
		print("Failed!")
		warn(errormessage)
	end
end)

I tried to make a different script to fix this problem, here is it’s code;

local DataStoreService = game:GetService("DataStoreService")
local StoreData = DataStoreService:GetDataStore("StoreleaderstatsData")

game.Players.PlayerAdded:Connect(function(plr)
	wait()
	local plrkey = "id_"..plr.UserId
	local Save1 = plr.leaderstats:FindFirstChild("Evolution Points")
	local Save2 = plr.leaderstats:FindFirstChild("XP")
	local Save3 = plr.leaderstats:FindFirstChild("Level")
	
	local GetSaved = StoreData:GetAsync(plrkey)
	if GetSaved then
		Save1 = GetSaved[1]
		Save2 = GetSaved[2]
		Save3 = GetSaved[3]
	else
		local NumberForSaving = {Save1.Value, Save2.Value, Save3.Value}
		StoreData:GetAsync(plrkey, NumberForSaving)
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	StoreData:SetAsync("id_"..plr.UserId, {plr.leaderstats["Evolution Points"].Value, plr.leaderstats.XP.Value, plr.leaderstats.Level.Value})
end)

They are both serverscripts inside of serverscriptservice.

Is “EvolutionPoints” a string, and integer, or something else? And why are you referencing it with brackets instead of referencing it the same way you did with XP and Level?

pienter2 · January 26, 2022, 7:23pm

Hello! You have to enable Access to API Services.You can find that in file, Game Settings, Security

1error I see in my game I can’t know if this works but hey here’s what I can see.

local DSS = game:GetService("DataStoreService")
local MDS = DSS:GetDataStore("myDataStore")
game.Players.PlayerAdded:Connect(function(plr)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = plr
	local EP = Instance.new("IntValue")
	EP.Name = "Evolution Points"
	EP.Parent = leaderstats
	local XP = Instance.new("IntValue")
	XP.Name = "XP"
	XP.Parent = leaderstats
	local Level = Instance.new("IntValue")
	Level.Name = "Level"
	Level.Parent = leaderstats
	local data
	local data2
	local data3
	local success, errormessage = pcall(function()
		data = MDS:GetAsync(plr.UserId.."-Evolution Points")
		data2 = MDS:GetAsync(plr.UserId.."-XP")
		data3 = MDS:GetAsync(plr.UserId.."-Level")
	end)
	if success then
		EP.Value = data
		XP.Value = data2
		Level.Value = data3
	else
		print("Failed!")
		warn(errormessage)
	end
end)
game.Players.PlayerRemoving:Connect(function(plr)
	local success, errormessage = pcall(function()
		MDS:SetAsync("id_"..plr.UserId, plr.leaderstats["Evolution Points"].Value, plr.leaderstats.XP.Value, plr.leaderstats.Level.Value)
	end)
	if success then
		print("Success!")
	else
		print("Failed!")
		warn(errormessage)
	end
end)

Because it has a space in the name. You can’t call anything with a number or space without using brackets.

MRBOGO_YT · January 26, 2022, 7:33pm

That and http requests are needed, and yes I have them both enabled.

Xethele · January 26, 2022, 7:34pm

Have you made this yourself? if so I could help! if not then I still can!

DevBoardQuestions · January 26, 2022, 7:36pm

You should use :FindFirstChild() to do this.

MRBOGO_YT · January 26, 2022, 7:37pm

Yes (the game with a team the scripts and guis myself). How would you help, me sending you the script, or letting you into a team create on our game.

Xethele · January 26, 2022, 7:38pm

Yep I would do that or I could simply just connect a db to save the leaderboard manually cause I’m into API instead and that

Xethele · January 26, 2022, 7:39pm

You shouldn’t really trust people easily so you only wanted to save the leaderboard right and have them on?

Official_ProGamerYT · January 26, 2022, 7:42pm

Try this!

local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("DataStoreV1")

game.Players.PlayerAdded:Connect(function(plr)

	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = plr

	local EP = Instance.new("IntValue")
	EP.Name = "Evolution Points"
	EP.Parent = leaderstats

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

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

	local key = plr.UserId

	local data
	local success,msg = pcall(function()
		data = DataStore:GetAsync(key)
	end)

	if data then
		print("Data Loaded")
		EP.Value = data.E
		XP.Value = data.X
		Level.Value = data.L
	else
		print("Error")
		warn(msg)
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	local key = player.UserId

	local data = {
		E = player.leaderstats["Evolution Points"].Value,
		X = player.leaderstats.XP.Value,
		L = player.leaderstats.Level.Value,
	}

	local success,msg = pcall(function()
		DataStore:SetAsync(key,data)
	end)

	if success then
		print("Data Saved!")
	end
end)

I understand that you’ve used alvinblox or someones tutorial so I will be posting a fix as fast as I can.

MRBOGO_YT · January 26, 2022, 7:45pm

It gets rid of the error and says that it has saved, but… It doesn’t save.

Official_ProGamerYT · January 26, 2022, 7:46pm

What script is like changing the value?

MRBOGO_YT · January 26, 2022, 7:48pm

There is no other script changing the values. For this test I have everything else that changes the values set to disabled.

Xethele · January 26, 2022, 7:50pm

Have you thought about saving it to their userid manually instead?

MRBOGO_YT · January 26, 2022, 7:51pm

no, how would I do that? via auto save? If so then how do you change the data manually?

Official_ProGamerYT · January 26, 2022, 7:51pm

Enable to scripts and test it to see if it works!

MRBOGO_YT · January 26, 2022, 7:55pm

It still doesn’t work… It looks like it is getting close though.
