Hey, I am trying to make a Level Value in my game, and I am wondering how I can make the Level Value, set to Level 1 if the player is new. How can I make this work correctly?

Here is my main script for DataStore:

-- leaderstats

local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("MainPlayerData")
local Players = game:GetService("Players")

local function saveData(player)
	local Key = "Player_"..player.UserId
	local success, err = pcall(function()
		local data = {
			player.leaderstats.Points.Value,
			player.leaderstats.Rubys.Value,
			player.leaderstats.playTime.Value,
			player.leaderstats.Deaths.Value,
			player.leaderstats.Kills.Value,
		}
		
		DataStore:SetAsync(Key, data)
		
	end)
	if (not success) then
		return warn("Player Data Did Not Save")
	end
	
	print("Data Saved Successfully")
end

local function loadData(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"

	local Points = Instance.new("IntValue")
	Points.Name = "Points"
	Points.Parent = leaderstats

	local Rubys = Instance.new("IntValue")
	Rubys.Name = "Rubys"
	Rubys.Parent = leaderstats

	local playTime = Instance.new("IntValue")
	playTime.Name = "playTime"
	playTime.Parent = leaderstats

	local Deaths = Instance.new("IntValue")
	Deaths.Name = "Deaths"
	Deaths.Parent = leaderstats

	local Kills = Instance.new("IntValue")
	Kills.Name = "Kills"
	Kills.Parent = leaderstats
	
	local roundKills = Instance.new("IntValue", player)
	roundKills.Name = "RoundKills"
	
	local Wins = Instance.new("IntValue", leaderstats)
	Wins.Name = "Wins"

	leaderstats.Parent = player

	player.CharacterAdded:Connect(function(char)
		local humanoid = char:WaitForChild("Humanoid", 2)
		if humanoid then
			humanoid.Died:Connect(function()
				Deaths.Value = Deaths.Value + 1

				local tag = humanoid:WaitForChild("creator", 2)
				if not tag then
				--[[ We could construct a new object to put in the humanoid here, 
				but will error and return here as we can't continue. ]]
					error("Failed to find "..tag" object in the Humanoid.")
					return
				end

			--[[ This was returning a string here, we need to get the player object of the killer!
			We can also use :FindFirstChild() here as the player should almost definitely exist here.]]
				local killer = Players:FindFirstChild(tag.Value) 
				if tag and killer then

					-- Leaderstats may not exist, so we'll find this properly too.
					local leaderstats = killer:WaitForChild("leaderstats", 2)
					if not leaderstats then
						error("Failed to find leaderstats folder in the killer.")
						return
					end
					
					-- Same with the round kills.
					local roundKillsObj = killer:FindFirstChild("RoundKills")
					if not roundKillsObj then
						error("Failed to find the 'RoundKills' object in the killer.")
						return
					end
					roundKillsObj.Value += 1

				--[[ From this point, we should be certain that the values in leaderstats will
				exist, but we'll use :FindFirstChild() anyway. ]]
					local killsValueObj = leaderstats:FindFirstChild("Kills")
					if not killsValueObj then
						error("Failed to find the 'Kills' object in the leaderstats folder.")
						return
					end
					killsValueObj.Value += 1
				end
			end)
		end
	end)


	local success, err = pcall(function()
		local key = "Player_"..player.UserId
		
		local data = DataStore:GetAsync(key)
		
		if data then
			Points.Value = data[1]
			Rubys.Value = data[2]
			playTime.Value = data[3]
			Deaths.Value = data[4]
			Kills.Value = data[5]
		end
	end)
	
	if (not success) then
		player:Kick("Data Failed To Load.")
		return warn("Player Data Did Not Save.")
	end
	
	print("Data Loaded Successfully.")

	while true do
		wait(60)
		playTime.Value = playTime.Value + 60
	end
end


game.Players.PlayerAdded:Connect(function(player)
	loadData(player)
end)

game.Players.PlayerRemoving:Connect(function(player)
	saveData(player)
end)

game:BindToClose(function()
	for _, v in pairs(Players:GetPlayers()) do
		saveData(v)
	end
end)

Thanks for your time,

Use an if statement to check if the player has any data.

Lol easy solution I guess. I just had to check just to make sure cause I don’t want to ruin the DataStore or the code.

Here is my code by the way:

Level.Value = data[7]
  if Level.Value >= 2 then
		print("Not a new player @ level system.")
  elseif Level.Value <= 1 then
		print("New At level System.")
		Level.Value = 1
		RequiredXP.Value = Level.Value * 100
   end
