Roblox Leaderboard Scripting Tutorial – Complete Guide

Welcome to Roblox leaderboard scripting! In this tutorial, we’re taking an in-depth look into how to design and implement leaderboards on Roblox, an essential tool for enhancing players’ gameplay experience. If you’ve been on the lookout for ways to motivate players to give their best in your game or to spice up the competition level, then you’re in the right place!

What Is Roblox Leaderboard Scripting?

Roblox leaderboard scripting refers to using Lua, Roblox’s in-built scripting language, to design and implement a leaderboard in a Roblox game. Leaderboards are often used in games to track and display players’ scores or accomplishments, fostering a competitive environment and embedding a sense of achievement.

Why Should I Learn It?

Being able to script your own leaderboard in Roblox equips you with an integral asset for your game creation toolbox. By encouraging competition, leaderboards keep players engaged and coming back for more. Plus, designing your own leaderboard allows for a high degree of customization, meaning you can tailor it to fit your game’s specific needs and style.

Furthermore, as you learn scripting for leaderboards, you naturally enhance your proficiency in Lua, a valuable skill set in the world of game creation. This skill adds an extra layer of interactivity for your players, enriching their in-game experience and increasing the potential of your game’s success in the Roblox universe.

Setting Up Your Leaderboard

First things first, you need to set up your leaderboard. To do this, you have to write a script that will create a leaderboard for each player that joins your game. Follow the steps below:

Ensure there is a ServerScriptService in your Roblox environment. This is where your script will live.

-- Check for ServerScriptService
local serverScriptService = game:GetService('ServerScriptService')

Next, insert a new script into the ServerScriptService. You can name this script ‘leaderboardScript’ for clarity.

-- Create new script in ServerScriptService
local leaderboardScript = Instance.new('Script')
leaderboardScript.Name = "leaderboardScript"
leaderboardScript.Parent = serverScriptService

Adding A Player Points System

With your leaderboard set, you can now add a player points tracking system. Let’s add a feature to track each player’s points:

Firstly, create a function to add a new player to the leaderboard. Each time a new player joins, this function will create a leaderboard for them:

-- Function to add new player to leaderboard
function addPlayerToLeaderboard(player)
    local leaderstats = Instance.new('Folder')
    leaderstats.Name = 'leaderstats'
    leaderstats.Parent = player

    local points = Instance.new('IntValue')
    points.Name = 'Points'
    points.Parent = leaderstats
    points.Value = 0
end

-- Connect function to PlayerAdded event
game.Players.PlayerAdded:Connect(addPlayerToLeaderboard)

The above script creates a new function addPlayerToLeaderboard where it first creates a new folder named ‘leaderstats’. In that folder, it creates a new IntValue named ‘Points’ and sets the initial value to 0.

It then connects the function to the PlayerAdded event, which means the function will run each time a new player joins the game.

Updating the Leaderboard

Now, if you want to increase a player’s points, you just need to access the ‘Points’ IntValue in the player’s leaderboard and update the value. Here’s how:

-- Function to add points
function addPoints(player, points)
    player.leaderstats.Points.Value = player.leaderstats.Points.Value + points
end

This script creates a new function addPoints that takes two arguments, the player and the number of points to add. It then reads the player’s current points, adds the new points to this total, and assigns the result back to the player’s points.

Now you can call this function whenever you want to add points to a player:

-- Call the function to add points to a player
addPoints(game.Players["PlayerName"], 10)

Replace “PlayerName” with the actual name of the player you want to award points to.

Adding Other Leaderboard Features

Once you have the basics of Roblox leaderboard scripting down, you can start adding unique features that fit the design of your game. Here are a few examples:

Tracking Player Properties

If your game involves more than just scoring points, you can add other values to your leaderboard. Let’s add a value to track the player’s health:

function addPlayerToLeaderboard(player)
    local leaderstats = Instance.new('Folder')
    leaderstats.Name = 'leaderstats'
    leaderstats.Parent = player

    local points = Instance.new('IntValue')
    points.Name = 'Points'
    points.Parent = leaderstats
    points.Value = 0

    local health = Instance.new('IntValue')
    health.Name = 'Health'
    health.Parent = leaderstats
    health.Value = 100 -- can set this to whatever initial health you prefer
end

Now, when a new player joins your game, they will have a leaderboard tracking both their points and health.

You can update this value the same way you updated points:

-- Function to reduce health
function reduceHealth(player, damage)
    player.leaderstats.Health.Value = player.leaderstats.Health.Value - damage
end

Creating a Persistent Leaderboard

If you want your leaderboard to store player data between game sessions, then you will need to use Roblox’s built-in data store. Here’s how you can set this up:

-- Get the DataStore service
local DataStoreService = game:GetService("DataStoreService")
local myDataStore = DataStoreService:GetDataStore("MyDataStore")

-- Add data store to addPlayerToLeaderboard function
function addPlayerToLeaderboard(player)
    local leaderstats = Instance.new('Folder')
    leaderstats.Name = 'leaderstats'
    leaderstats.Parent = player

    local points = Instance.new('IntValue')
    points.Name = 'Points'
    points.Parent = leaderstats
    
    -- Load player data from data store
    local data = myDataStore:GetAsync(tostring(player.UserId))
    if data then
        points.Value = data.Points
    else
        points.Value = 0
    end
end

-- Save data to data store when player leaves game
game.Players.PlayerRemoving:Connect(function(player)
    local data = {
        Points = player.leaderstats.Points.Value,
    }
    myDataStore:SetAsync(tostring(player.UserId), data)
end)

This script sets up a data store that retrieves saved data when a player joins and stores player data when they leave. Note that data stored can persist across games, servers, and even game sessions!

Handling Multiple Leaderboards

In some cases, you might want multiple leaderboards for different game modes or maps. Creating multiple leaderboards is as easy as creating multiple ‘leaderstats’ folders and setting their parent to the player as shown above.

For example, you could create one leaderboard for a campaign mode and another for a survival mode:

function addPlayerToLeaderboard(player)
    -- set up campaign leaderboard
    local campaignStats = Instance.new('Folder')
    campaignStats.Name = 'CampaignStats'
    campaignStats.Parent = player

    local campaignPoints = Instance.new('IntValue')
    campaignPoints.Name = 'Points'
    campaignPoints.Parent = campaignStats
    campaignPoints.Value = 0

    -- set up survival leaderboard
    local survivalStats = Instance.new('Folder')
    survivalStats.Name = 'SurvivalStats'
    survivalStats.Parent = player

    local survivalPoints = Instance.new('IntValue')
    survivalPoints.Name = 'Points'
    survivalPoints.Parent = survivalStats
    survivalPoints.Value = 0
end

This creates two different leaderboards for the player: one for the campaign mode and one for the survival mode. You can customize these stats to suit the needs of your particular game modes.

Displaying the Leaderboard

After setting up the leaderboards, players need to be able to see their stats. Here is how you can script a basic GUI to display a player’s points:

-- Function to update a player's points on GUI
function updatePointsGUI(player)
    local pointsGUI = game.StarterGui:WaitForChild("PointsGUI")
    local pointsText = pointsGUI:WaitForChild("PointsText")

    -- loop to keep the GUI updated
    while true do
        pointsText.Text = "Points: "..player.leaderstats.Points.Value
        wait() -- this makes the loop wait for 1 second before repeating
    end
end

-- Connect the function to PlayerAdded event
game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAdded:Wait() 
    updatePointsGUI(player)
end)

The above script sets up a loop to consistently update the player’s points in the GUI. The “wait()” call at the end of the loop ensures a one-second delay before the panel updates again, reducing the computation needed to keep the GUI updated.

Incorporating Leaderboards into Gameplay

Let’s say you have a game where players score points by collecting items. Here, you can integrate the leaderboard to update whenever a player collects an item:

-- Function to add points
function addPoints(player, points)
    player.leaderstats.Points.Value = player.leaderstats.Points.Value + points
end

-- Function to handle a player touching an item
function handleTouchItem(player, points)
    -- only award points if the object touched is an item
    touched.Touched:Connect(function(part)
        if part.Parent == player.Character then
            addPoints(player, points)
            -- destroy item after collection
            item:Destroy() 
        end
    end)
end

This script adds a handleTouchItem function that checks if a player character has touched an item. When this happens, the game adds points to the player’s score and then destroys the item.

Challenging Players with Special Conditions

If you want to challenge your players further, you can set special conditions that can affect their leaderboard rankings. For example, you could create diminishing returns by reducing the points gained each time a player collects an item:

-- Function to add points with diminishing returns
function addPoints(player, points)
    -- reduce points by half each time
    player.leaderstats.Points.Value = player.leaderstats.Points.Value + (points / 2)
end

This script modifies the addPoints function so that each time it’s called, the points added to the player’s score become half of what they were the last time.

Sorting the Leaderboard

Your leaderboard may contain scores of hundreds of players. Here’s how you can sort the leaderboard based on player scores:

function sortLeaderboard()
    -- Get a table of all players
    local allPlayers = game.Players:GetPlayers()
    -- Sort the table based on player points
    table.sort(allPlayers, function(a, b)
        return a.leaderstats.Points.Value > b.leaderstats.Points.Value
    end)
    return allPlayers
end

This function fetches all current players, sorts them based on their points from highest to lowest, and returns the sorted list of players. Now, you can display the sorted leaderboard to the players or use it for any other purposes.
