I need help with Data Store I am very new to data store could you please help?

I am very new to Data Store and I am trying to store the Resources wood, stone, flax, pila into a data store so whenever the player leaves the game if the value was added or subtracted it would save upon his/hers next rejoin.

I need to save Resources.

Here is the code:

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local ItemIndex = require(ReplicatedStorage:WaitForChild("ItemIndex")) local ApplyStandardIssue = require(script:WaitForChild("StandardIssue")) local PlayerInventoryFetch = ReplicatedStorage:WaitForChild("PlayerInventoryFetch") local PlayerInventoryUpdate = ReplicatedStorage:WaitForChild("PlayerInventoryUpdate") local PlayerInventoryEquipItem = ReplicatedStorage:WaitForChild("PlayerInventoryEquipItem")

local RESOURCE_MAX = { pila = 2 }

local PlayerInventories = {}

function AttachToCharacter(player, accessory) if accessory:IsA("Accessory") then player.Character.Humanoid:AddAccessory(accessory:Clone()) elseif accessory:IsA("Model") then local model = accessory:Clone()

	local weld = Instance.new("ManualWeld")
	weld.Part0 = model.Handle
	weld.Part1 = player.Character[model.AttachPart.Value]
	weld.Parent = model.Handle

	model.Parent = player.Character
end

end

function FireInventoryUpdate(player, forceEquip) PlayerInventoryUpdate:FireClient(player, PlayerInventories[player.UserId], forceEquip) end

function AddToInventory(player, name, options) table.insert(PlayerInventories[player.UserId].Items, { Id = name, UniqueName = ItemIndex.Items[name].Name .. " " .. tick() .. " " .. math.random(1, 1000), Equipped = options.Equipped or false, StandardIssue = options.StandardIssue or false, FamiliarTemplate = options.FamiliarTemplate })

if not options.SkipUpdateEvent then
	FireInventoryUpdate(player)
end

end

game.Players.PlayerAdded:Connect(function(player) local CharacterAppearanceConnection CharacterAppearanceConnection = player.CharacterAppearanceLoaded:Connect(function(character) CharacterAppearanceConnection:Disconnect() wait(0.6) if character:FindFirstChild("Shirt") then AddToInventory(player, "shirt_familiar", {Equipped=true, FamiliarTemplate=character.Shirt.ShirtTemplate}) end

	if character:FindFirstChild("Pants") then
		AddToInventory(player, "pants_familiar", {Equipped=true, FamiliarTemplate=character.Pants.PantsTemplate})
	end
end)

wait(0.5)
if not PlayerInventories[player.UserId] then
	PlayerInventories[player.UserId] = {
		Resources = {wood = 1000, stone = 1000, flax = 1000, pila = 2},

end

end)

end```

Here let me make it look simple.

local resources = {}
local d = game:GetService("DataStoreService"):GetDataStore("R")
game.Players.PlayerAdded:Connect(function(p)
	local retrieved = d:GetAsync(p.UserId)
	if retrieved then
		resources[p.Name] = retrieved
	else
		resources[p.Name]["Wood"] = 1
	end
end)
game.Players.PlayerRemoving:Connect(function(p)
	resources[p.Name]["Wood"] = resources[p.Name]["Wood"] + 1
	d:SetAsync(p.UserId,resources[p.Name])
end)
