How to make a global leaderboard using DataStore2?

I was following this tutorial: How to make a simple global leaderboard when i realized that this probably wouldn’t work because i am using DataStore2 (and it didn’t), so i went googling around to see if i could find any tutorial or people teaching it and i found the following posts related to it:

I got that OrderedDataStore doesn’t work with DataStore2 but even looking around and getting examples of what should i do, i don’t understand what must be done in order for it to work, can someone help me or give a better explanation (i am quite new to scripting and DataStore2)

My Current Script(Global Leaderboard Part/GUI):

local DataStore2 = require(game:GetService("ServerScriptService").DataStore2)

local sg = script.Parent
local sample = script:WaitForChild("Sample") --Our Sample frame
local sf = sg:WaitForChild("ScrollingFrame") --The scrolling frame
local ui = sf:WaitForChild("UI") --The UI list layout

local dataStoreService = game:GetService("DataStoreService")
--The data store service
local dataStore = dataStoreService:GetOrderedDataStore("Leaderboard")
--Get the data store with key "Leaderboard"

wait(10)
while true do
	for i,plr in pairs(game.Players:GetChildren()) do--Loop through players
		if plr.UserId>0 then--Prevent errors
			local ps = game:GetService("PointsService")--PointsService
			local w = ps:GetGamePointBalance(plr.UserId)--Get point balance
			if w then
				pcall(function()
				--Wrap in a pcall so if Roblox is down, it won't error and break.
					dataStore:UpdateAsync(plr.UserId,function(oldVal)
				        --Set new value
						return tonumber(w)
					end)
				end)
			end
		end
	end    
	local smallestFirst = false--false = 2 before 1, true = 1 before 2
    local numberToShow = 100--Any number between 1-100, how many will be shown
    local minValue = 1--Any numbers lower than this will be excluded
    local maxValue = 10e30--(10^30), any numbers higher than this will be excluded
    local pages = dataStore:GetSortedAsync(smallestFirst, numberToShow, minValue, maxValue)
    --Get data
    local top = pages:GetCurrentPage()--Get the first page
	local data = {}--Store new data
	for a,b in ipairs(top) do--Loop through data
		local userid = b.key--User id
		local points = b.value--Points
		local username = "[Failed To Load]"--If it fails, we let them know
		local s,e = pcall(function()
		 username = game.Players:GetNameFromUserIdAsync(userid)--Get username
		end)
		if not s then--Something went wrong
		   warn("Error getting name for "..userid..". Error: "..e)
		end
		local image = game.Players:GetUserThumbnailAsync(userid, Enum.ThumbnailType.HeadShot, Enum.ThumbnailSize.Size150x150)
		--Make a image of them
		table.insert(data,{username,points,image})--Put new data in new table
	end
	ui.Parent = script
	sf:ClearAllChildren()--Remove old frames
	ui.Parent = sf
	for number,d in pairs(data) do--Loop through our new data
		local name = d[1]
		local val = d[2]
		local image = d[3]
		local color = Color3.new(1,1,1)--Default color
		if number == 1 then
			color = Color3.new(1,1,0)--1st place color
		elseif number == 2 then
			color = Color3.new(0.9,0.9,0.9)--2nd place color
		elseif number == 3 then
			color = Color3.fromRGB(166, 112, 0)--3rd place color
		end
		local new = sample:Clone()--Make a clone of the sample frame
		new.Name = name--Set name for better recognition and debugging
                new.LayoutOrder = number--UIListLayout uses this to sort in the correct order
		new.Image.Image = image--Set the image
		new.Image.Place.Text = number--Set the place
		new.Image.Place.TextColor3 = color--Set the place color (Gold = 1st)
		new.PName.Text = name--Set the username
		new.Value.Text = val--Set the amount of points
		new.Value.TextColor3 = color--Set the place color (Gold = 1st)
		new.PName.TextColor3 = color--Set the place color (Gold = 1st)
		new.Parent = sf--Parent to scrolling frame
	end
	wait()
	sf.CanvasSize = UDim2.new(0,0,0,ui.AbsoluteContentSize.Y)
	--Give enough room for the frames to sit in
        wait(120)
end

How/why do you want to connect DataStore2 with this script? I see no use of datastore2 in your script, if you explained this it would be helpful.

I was following this example: Making global leaderboard with DataStore2 then i thought the DataStore2 would be necessary, so i just created a variable for DataStore2 but didn’t use it anywhere because i had no clue what to do

What is your use case for using data store 2? Data store 2 is for regular data stores. The only way to use data store 2 with this is to have 2 separate data keys, the regular data store 2, and the ordered data store.

Example:

OrderedDataStores are separate from regular ones, which is what data store 2 uses. If you wanted, you could use the ordered data store to save a certain statistic and data store 2 for everything else, or the example above.
