Need help with saving tables

Help and Feedback Scripting Support
#1

Hello,

So as the title says I need some help with saving tables. Those tables contain Names and values the name represents the Name of the IntValue and value well it represents the value.

I tried to make a script which would save it but it doesn’t works and I don’t know why. This is the current script:

local dss = game:GetService("DataStoreService")
local InventoryData = dss:GetDataStore("InventoryDataStore")

local currentItems = game:GetService("ServerStorage").Items:GetChildren()

game.Players.PlayerAdded:Connect(function(player)
	
	local key = "player_Inv" .. player.UserId
	local inventory = InventoryData:GetAsync(key)
	
	local folder = Instance.new("Folder", game:GetService("ServerStorage"):WaitForChild("Inventory"))
	folder.Name = player.Name
	

	for _, data in ipairs(inventory or { }) do
		print("loop works")
		local amount = player.Character:FindFirstChild(data).Value
		print("can get the amount")
		
		local Ival = Instance.new("IntValue", player.Character)
		Ival.Value = amount
		Ival.Name = data
		print("can get the value")
	end
	
end)

game.Players.PlayerRemoving:Connect(function(player)
	local key = "player_Inv" .. player.UserId
	local tools = { }
	local saveInventory = player.Character
	
	for _, item in next, saveInventory do
		if item.Name ~= currentItems.Name then
			print("No item is in the player's inventory")
		else
			table.insert(tools, {
				Name = item.Name,
				Amount = item.Value

			})
		end
			
		print("table has been inserted")
	end
	InventoryData:UpdateAsync(key, function(prev)
		print("Inventory has been saved")
		return tools
	end)
	
end)

Thanks for helping!

Try to use httpservice to encode and decode the table into JSON

#3

Also could you please send the output? Ty

#4

Can you show me how this works? Cause I can’t find anything of to do this.

#5

I am on my phone so I can’t do a good job, but I will try. Could you please send a screenshot of the output also?

local http = game:GetService(“HTTPservice”) —might have spelled this wrong

—encode data
Data = http:JSONEncode(Data)

—decode data
Data = http:JSONDecode(Data)

Sorry for any caps or spelling errors, am on phone. Make sure to replace “Data” with what you want to encode/ decode

#6

The output says nothing I know that it doesn’t works cause the print statements don’t work.

#7

Where do I need to put the encode one and the decode one?

local dss = game:GetService("DataStoreService")
local InventoryData = dss:GetDataStore("InventoryDataStore")
local http = game:GetService("HttpService")


local currentItems = game:GetService("ServerStorage").Items

game.Players.PlayerAdded:Connect(function(player)
	local key = "player_Inv" .. player.UserId
	local inventory = http:JSONDecode(key)
	
	
	local folder = Instance.new("Folder", player)
	folder.Name = player.Name .. " Obt"
	
	for i, v in pairs(currentItems:GetChildren()) do
		local Int = Instance.new("IntValue", folder)
		Int.Name = v.Name
	end
	
end)


game.Players.PlayerRemoving:Connect(function(player)
	local key = "player_Inv" .. player.UserId
	local InventoryIt = { }
	local saveInventory = player:WaitForChild(player.Name .. " Obt")
	
	for _, item in next, saveInventory do
		table.insert(InventoryIt, {
			Name = item.Name,
			Amount = item.Value
		})
		
	end
	InventoryData:UpdateAsync(key, function(prev)
		http:JSONEncode(InventoryIt)
	end)
	
end)

This is my current script its not finished can you give me feedback?

Sorry for the late response, as I am away I can’t get the example of json encoding and decoding.

You don’t need the key to encode or decode json, you just need the table data. So instead of encoding the key, encode the data. Also encode should be directly before you store it, and decode should be directly after you get the data

#10

Whenever you are using UpdateAsync then you have to return the data you are saving.

Fixed:

InventoryData:UpdateAsync(key, function(prev)
	return http:JSONEncode(InventoryIt)
end)
#11

And how would I add the values into the intvalues which have the same name so the Ore(IntValue name) and its value won’t be the wheat value.

#12 
local dss = game:GetService("DataStoreService")
local InventoryData = dss:GetDataStore("InventoryDataStore")
local http = game:GetService("HttpService")



local currentItems = game:GetService("ServerStorage").ItemsValue

game.Players.PlayerAdded:Connect(function(player)
	local data = {}
	
	local folder = Instance.new("Folder", player)
	folder.Name = player.Name .. "Obt"
	
	if data then
		data = http:JSONDecode(data)
		
		if data["Coal Ore"] ~= nil then
			if data["Coal Ore"] > 0 then
				local id400 = Instance.new("IntValue", folder)
				id400.Name = "Coal Ore"
				id400.Value = data["Coal Ore"]
			end
		end
		if data["Iron Ore"] ~= nil then
			if data["Iron Ore"] > 0 then
				local id402 = Instance.new("IntValue", folder)
				id402.Name = "Iron Ore"
				id402.Value = data["Iron Ore"]
			end
		end
		
	end
	
end)


game.Players.PlayerRemoving:Connect(function(player)
	local inv = {}
	
	for i, v in pairs(player:FindFirstChild(player.Name .. "Obt"):GetChildren()) do
		
		if v.Value then
			inv[v.Name] = v.Value
		end
	end
	pcall(function()
		InventoryData:SetAsync(player.UserId, http:JSONEncode(inv))
	end)
end)

This is my current script now but it doesn’t works can you help me with this?
