How can I add datastore to this script?

Before you copy and paste my script, let me give advice and info to the thread

  • Don’t use parent as an argument for Instance.new() because it takes much longer

  • Use :BindToClose instead of PlayerRemoving or else the Data won’t save if a player loses connection or if the game shuts down. PlayerRemoving only works when a player leaves the game intentionally.

@regexman weren’t you the one who told me to use BindToClose instead of PlayerRemoving in the first place?

local Players = game:GetService("Players")
local DataStore = game:GetService("DataStoreSerivce"):GetDataStore("DataStoreValues")
local RunService = game:GetService("RunService")

game.Players.PlayerAdded:Connect(function(player)
local leaderstats = Instance.new("Folder")
leaderstats.Parent = player
leaderstats.Name = "leaderstats"

local Strength = Instance.new("IntValue")
Strength.Parent = leaderstats
Strength.Name = "Strength"
Strength.Value = 1

local Exp = Instance.new("NumberValue")
Exp.Parent = leaderstats
Exp.Name = "Exp"
Exp.Value = 0

local RequiredExp = Instance.new("NumberValue")
local
RequiredExp.Name = "RequiredExp"
RequiredExp.Value = Strength.Value * 100

Exp.Changed:Connect(function(Changed)
	if Exp.Value >= RequiredExp.Value then
		Exp.Value = 0
		
		Strength.Value += 1
		RequiredExp.Value = Strength.Value * 100
	end
end)

local value1Data = Strength
local value2Data = Exp

	local s, e = pcall(function()
		value1Data = DataStore:GetAsync(player.UserId.."-Value1") or 0 --check if they have data, if not it'll be "0"
        value2Data = DataStore:GetAsync(player.UserId.."Value1") or 0
	end)

	if s then
		Strength.Value = value1Data --setting data if its success
        Exp.Value = value2Data
	else
		game:GetService("TestService"):Error(e)  --if not success then we error it to the console
	end
end)

game:BindToClose(function(player)
if not RunService:IsStudio()
local s, e = pcall(function()
	DataStore:SetAsync(player.UserId.."-Value1", player.leaderstats.Strength.Value) --setting data
    DataStore:SetAsync(player.UserId.."-Value2", player.leaderstats.Exp.Value)
	end)
	    if not s then game:GetService("TestService"):Error(e) 
	end

    end)
end)
