Shop data store cash?

[Cleetaros]

I’m using a kit to set up a shop system, how would I add datastore to this?

local items = game.ReplicatedStorage:WaitForChild("Items")


game.Players.PlayerAdded:Connect(function(plr)
	
	
	local ls = Instance.new("Folder")
	ls.Name = "leaderstats"
	ls.Parent = plr
	
	local cash = Instance.new("IntValue")
	cash.Name = "Cash"
	cash.Value = 1000
	cash.Parent = ls
end)


game.ReplicatedStorage:WaitForChild("OnItemBought").OnServerEvent:Connect(function(plr, itemBought)
	
	if itemBought and itemBought:IsA("Tool") and itemBought.Parent == items then
		
		
		local cash = plr.leaderstats.Cash
		
		if cash.Value >= itemBought.ShopGuiInfo.Price.Value then
			
			cash.Value -= itemBought.ShopGuiInfo.Price.Value
			
			itemBought:Clone().Parent = plr.Backpack
		end
	end
end)```

Just use datastore service, use get async to get the value saved or 1000 and a playerremoving function and save it inside of there.

local items = game.ReplicatedStorage:WaitForChild("Items")
local cashds = game:GetService("DataStoreService"):GetDataStore("Cash")

game.Players.PlayerAdded:Connect(function(plr)
	
	
	local ls = Instance.new("Folder")
	ls.Name = "leaderstats"
	ls.Parent = plr
	
	local cash = Instance.new("IntValue")
	cash.Name = "Cash"
	cash.Value = cashds:GetAsync(plr.UserId) or 1000 --get the data or if there is no data 1000 start cash.
	cash.Parent = ls
end)


game.ReplicatedStorage:WaitForChild("OnItemBought").OnServerEvent:Connect(function(plr, itemBought)
	
	if itemBought and itemBought:IsA("Tool") and itemBought.Parent == items then
		
		
		local cash = plr.leaderstats.Cash
		
		if cash.Value >= itemBought.ShopGuiInfo.Price.Value then
			
			cash.Value -= itemBought.ShopGuiInfo.Price.Value
			
			itemBought:Clone().Parent = plr.Backpack
		end
	end
end)

--save it

game.Players.PlayerRemoving:Connect(function(plr)
	cashds:SetAsync(plr.UserId, plr.leaderstats.Cash.Value)
end)

I have a few data saving modules that you should take the time to learn!

Andrew bereza’s super cool data module (super easy and efficent):

How to use DataStore2 - Data Store caching and data loss prevention

DataStore2 Documentation | News | Source DataStore2 is an open source module that uses berezaa’s method of saving data that prevents data loss, caches, and verifies data before saving. DataStore2 has been used in my game visited by 120 million players with a constant concurrent player count of around 3,000 - 8,000 players, one time reaching 12,000 concurrent players. @AlreadyPro’s latest game Fairy World has 3 million visits and a consistent concurrent player count above 1,000, and a peak of 5…

I have literally never had data issues with either of these modules
