Help with datastore error?

[AlekGamer_TV (alek)]

Hi! I’ve been making a game where the jump power goes up by one every second, it worked initially but now it is no longer working and I have no idea why, heres my code:

local DataStoreService = game:GetService("DataStoreService")
local myDataStore = DataStoreService:GetDataStore("myDataStore")

local function updateJump(Humanoid, Jump)
    Humanoid.UseJumpPower = true
    Humanoid.JumpPower = Jump
end

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

    local Jump = Instance.new("IntValue")
    Jump.Name = "Jump Power"
    Jump.Parent = leaderstats
    
    local Win = Instance.new("IntValue")
    Win.Name = "Wins"
    Win.Parent = leaderstats

    local playerUserId = "Player"..player.UserId

    local data

    local success, errormessage = pcall(function()
        data = myDataStore:GetAsync(playerUserId) 
    end)

    if success then
        Jump.Value = data -- loads jump power
        Win.Value = data -- loads wins
    end
    player.CharacterAdded:Connect(function(Character)
        while wait(1) do
            player.leaderstats.Jump.Value += 1 -- makes the jump power go up every secodn
            updateJump(Character.Humanoid, Jump.Value)
        end 
    end)
end)

game.Players.PlayerRemoving:Connect(function(player)
    local playerUserId = "Player"..player.UserId
    local data = player.leaderstats.Jump.Value
    local data = player.leaderstats.Win.Value
    
    myDataStore:SetAsync(playerUserId, data) --saves the persons data when they leave
end)

The error message is:

Jump is not a valid member of Folder "Players.AlekGamer_TV.leaderstats"  -  Server - Main:44

The erroring line is this:

local data = player.leaderstats.Jump.Value

The issue is that you created the object with the name of “Jump Power” instead of Jump, so no object called Jump exists!
To correct this issue, have it as

local data = player.leaderstats["Jump Power"].Value

---

Also, your jump power isn’t going to save either way. Although you initially get the value and save it to data, the data variable is redefined the next line as the amount of wins they have. To save the 2 variables will be a bit more complicated, involving saving it as json instead. I’ll write out the code instead of trying to explain anything, but if you get confused on anything let me know!

local DataStoreService = game:GetService("DataStoreService")
local myDataStore = DataStoreService:GetDataStore("myDataStore")
local HTTPService = game:GetService("HttpService")

local function updateJump(Humanoid, Jump)
	Humanoid.UseJumpPower = true
	Humanoid.JumpPower = Jump
end

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

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

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

	local playerUserId = "Player"..player.UserId

	local dataRaw

	local success, errormessage = pcall(function()
		dataRaw = myDataStore:GetAsync(playerUserId) 
	end)

	if success then
		local data = HTTPService:JSONDecode(dataRaw)
		Jump.Value = data["Jump"] -- loads jump power
		Win.Value = data["Win"] -- loads wins
	end
	player.CharacterAdded:Connect(function(Character)
		while wait(1) do
			player.leaderstats.Jump.Value += 1 -- makes the jump power go up every secodn
			updateJump(Character.Humanoid, Jump.Value)
		end 
	end)
end)

game.Players.PlayerRemoving:Connect(function(player)
	local playerUserId = "Player"..player.UserId
	local data = {
		["Jump"] = player.leaderstats["Jump Power"].Value,
		["Win"] = player.leaderstats.Wins.Value
	}

	myDataStore:SetAsync(playerUserId, HTTPService:JSONEncode(data)) --saves the persons data when they leave
end)
