Data Storing a CFrame value?

So I've been working on a Roblox RPG and for four days I've been trying to make a save and load system. But I've had no success. I'm trying to use a Script in ServerScriptService to give the player a CFrame value and when the player presses a save button, the CFrame updates and when they leave it stays the same. I've looked all over to find any answer but no success in what I'm trying to do. So far this is what I have in my DataStore Script.

local DataStore = game:GetService("DataStoreService")
local save = DataStore:GetDataStore("SavePos")

game.Players.PlayerAdded:Connect(function(plr)
    local spot = Instance.new("Folder",plr)
    spot.Name = "SaveLocation"

    local pos = Instance.new("CFrameValue",spot)
    pos.Name = "PlayerPosition"
end)

This is all I have, there used to be more but I deleted it since it wouldn't work. Any help is appreciated, thank you.

EDIT - So with the buttons I've made a little test to get the buttons from PlayerGui,

local DataStore = game:GetService("DataStoreService")
local save = DataStore:GetDataStore("SavePos")
local saveButton = game.Players.LocalPlayer.PlayerGui.ScreenGui.TextButton
local loadButton = game.Players.LocalPlayer.PlayerGui.ScreenGui.OtherButton

game.Players.PlayerAdded:Connect(function(plr)
    local spot = Instance.new("Folder",plr)
    spot.Name = "SaveLocation"

    local pos = Instance.new("CFrameValue",spot)
    pos.Name = "PlayerPosition"

    pos.Value = save:GetAsync(plr.UserId) or 0

    saveButton.MouseButton1Click:Connect(function()

    end)

    loadButton.MouseButton1Click:Connect(function()

    end)

end)

Now I want it to update pos.Value when saveButton is clicked on the HumanoidRootPart.CFrame, then maybe save could be used, not sure how really though, DataStores are not my strong suite. Then when you leave and come back, pressing loadButton would then load your position etc.

This system can be very problematic if the map changes. A player could be positioned within a house that changes position. I would just spawn the player at the closes spawn position ingame. User#5423 17 — 5y

So make a system where when the player leaves, he'll rejoin at the same spawn? Notrealac0unt 19 — 5y

dude,save the value as an int,then just use that int inside the CFrame,like CFrame.new(num), Danielp533 16 — 5y

listen for when the button is clicked and fire to the server to save the position of the player. also the parent argument of Instance.new() is deprecated, set the parent last.

local DataStore = game:GetService("DataStoreService")
local save = DataStore:GetDataStore("SavePos")
local rm = game.ReplicatedStorage.RemoteEvent -- mayb this was the remote event

local function updateData(plr) -- update data
    local key = "id_"..plr.UserId

    pcall(function()
        save:UpdateAsync(key, function(old)
            return plr.SaveLocation.PlayerPosition.Value or old -- return the new value or the old one
        end)
    end)
end

game.Players.PlayerAdded:Connect(function(plr)
    local spot = Instance.new("Folder")
    local key = "id_"..plr.UserId

    spot.Name = "SaveLocation"
    spot.Parent = plr

    local pos = Instance.new("CFrameValue")
    pos.Name = "PlayerPosition"
    pos.Parent = spot

    local getPos = save:GetAsync(key)

    if getPos then
        local char = plr.Character or plr.CharacterAdded:Wait()

        pos.Value = getPos
        char:SetPrimaryPartCFrame(pos.Value)
    end

    local canSave = true

    rm.OnServerEvent:Connect(function(player, savePosition) -- listen for when the client clicks the save button
        if savePosition == "savePosition" and canSave then
            updateData(player) -- update the players pos
            print("saved!")
            canSave = false
            wait(10) -- to prevent it from updating the data too much which results in overloading the queue
            canSave = true
        end
    end)
end)

client

local button = script.Parent -- define where the button is
local rm = game.ReplicatedStorage.RemoteEvent

button.Activated:Connect(function()
    rm:FireServer("savePosition")
end)

and to clarify the client, (I tried remote functions like this before) I'd put the client script in a LocalScript IN the save button? Notrealac0unt 19 — 5y

sure User#23365 30 — 5y

also its remote events, remote functions are for returning values User#23365 30 — 5y

Yup got that I'll let you know if this works, thanks for all your help so far. Notrealac0unt 19 — 5y
