How to make a game leaderboard in Roblox?

To create a leaderboard for your Roblox game, follow these steps:

1. Open your Roblox Studio and navigate to the game you want to add the leaderboard to.
2. In the "Explorer" window, click the "+" button to create a new object.
3. Select "DataStore2" from the list of available objects.
4. Rename the DataStore2 object to something like "Leaderboard".
5. In the Properties window for the Leaderboard object, set the "Scope" property to "Global".
6. In the "Leaderboard" object, create a new Script by clicking the "+" button.
7. Paste the following code into the script:

local datastore = game:GetService("DataStoreService"):GetDataStore("Leaderboard")

game.Players.PlayerAdded:Connect(function(player)
    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player
    
    local leaderboard = Instance.new("IntValue")
    leaderboard.Name = "Leaderboard"
    leaderboard.Parent = leaderstats
    
    local success, result = pcall(function()
        return datastore:GetAsync(player.UserId)
    end)
    
    if success and result then
        leaderboard.Value = result
    else
        leaderboard.Value = 0
    end
    
    leaderboard.Changed:Connect(function(newValue)
        local success, result = pcall(function()
            return datastore:SetAsync(player.UserId, newValue)
        end)
        
        if not success then
            print("Error saving leaderboard value: " .. result)
        end
    end)
end)

This code will create a new DataStore2 object to store the leaderboard data, and then create a new "leaderstats" folder for each player that joins the game. It will also create a new "Leaderboard" value in the "leaderstats" folder, which will display the player's current leaderboard score.

When a player joins the game, the script will check if they have a leaderboard score stored in the DataStore2 object. If they do, it will set their leaderboard score to that value. If they don't, it will set their score to 0.

Whenever a player's leaderboard score changes, the script will save the new value to the DataStore2 object.

1. Save the script and publish your game.

Now, whenever a player joins your game, they will have a leaderboard score displayed in the "leaderstats" folder. This score will be stored in the DataStore2 object, so it will persist even if the player leaves the game and comes back later.
