How do I make things stack on the values of things already in my inventory | DataStore2

I’ve been having this issue where I want items to continuously add to the value say you have one sword then instead of making another sword it just adds to the value of that one sword.

How do you save data? In a JSON string I assume.

That’s not even my issue, my guy

thing.Value = "sword1"
thing.Value = thing.Value..",sword2"

then to get the strings:

local ownedItems = thing.Value:split(",")
print(ownedItems[2])
-- which becomes: ownedItems = {"sword1","sword2"}
-- this may return blank values so either make sure to loop and check then remove them/ensure the value is never just " " before adding something new to it, i.e:
if thing.Value == " " then
    thing.Value = "sword1"
else
    thing.Value = ownedItems.Value..",sword2"
end

I think this might be what you mean, if not then elaborate further in a reply and I’ll do my best to help

sorry if this is messy, typing it here instead of on Studio

Sorry but, uh let me have you take a look at my loading script for the inventory

local function UpdateInventory(Default)
		local tab = InventoryStore:GetTable(Defaults)
		for i,v in pairs(tab) do
			if Inventory:FindFirstChild(v) then
		else
			print("Adding New Item!")
			local item = Instance.new("NumberValue")
			item.Name = v[1]
			item.Value = v[2]
			item.Parent = Inventory
		end
	end
end
6

If theres already an item I want to make the value + 1

When I pick it up again of course!

8 
		local tab = InventoryStore:GetTable(Defaults)
		for i,v in pairs(tab) do
			if Inventory:FindFirstChild(v) then
                            Inventory[v][1].Value = Inventory[v][1].Value + 1
		else
			print("Adding New Item!")
			local item = Instance.new("NumberValue")
			item.Name = v[1]
			item.Value = v[2]
			item.Parent = Inventory
		end
	end
end

you mean like this? it +1s if it is found (remember FFC takes a string so if v isn’t a string it FFC won’t work)

So basically the v is the name of item inside of the table

10

Edited version should be right, lemme know if it works or not

11

RATS, its not working man!! Fridge what could be wrong

12

Show me your output, might’ve done something wrong with the indexing

Im picking up the item but its value is staying at 1! sadly also their is nothing in the output

Here is the script when I pick up the item

for i,v in ipairs(Pickupables.Weapons) do
		if item and item.Name == v and (item.PrimaryPart.Position - humrp.Position).Magnitude <= 5 and item then
			if Inventory:FindFirstChild(item.Name) then
				for i,v in pairs(Inventory:GetChildren()) do
					if v.Name == item.Name then
						print(v.Name)
					end
				end
			elseif not Inventory:FindFirstChild(item.Name) then
				local Put = Instance.new("NumberValue")
				Put.Name = item.Name
				Put.Value = 1
				print("The player has just picked up a "..item.Name)
				table.insert(InventoryTable, {Put.Name, Put.Value})
				InventoryStore:Set(InventoryTable)
				item:Destroy()
				print("Testing")
			end
		end
	end
end)
15

You’re setting the value to 1, not incrementing it by 1

Put.Value = Put.Value + 1
16

Dude thats when the player doesnt already have the item in their inventory!

17

What is item set as?

Why are you searching for item in two different ways? There’s also no modification of the IntValues anywhere

if Inventory:FindFirstChild(item.Name) then
     Inventory[item.Name].Value = Inventory[item.Name].Value + 1 -- this would be an IntValue, correct?

Yes, Ghnarwhal that works but it doesnt save at all, Ive tried that
