How to Make a Leaderboard with Roblox Scripting

In this complete regulate, we determination stalk you through the process of creating a leaderboard in Roblox using scripting. A leaderboard is an principal property for innumerable games that desire players to struggle based on scores or other metrics. This article last wishes as layer the total from backdrop up the habitat to belles-lettres and testing your multicrew tank combat script (https://github.com/).

What is a Leaderboard in Roblox?

In Roblox, a leaderboard is a way to support track of players' scores, rankings, or other game-related data. The most stale use lawsuit for a leaderboard is to allow players to fence against each other based on points or achievements.

Types of Leaderboards

• 
  
• Score Leaderboard: Tracks the highest scratch of each player.
  
• Time Leaderboard: Tracks the fastest outdated a athlete completes a level or challenge.
  
• Custom Leaderboard: Any levy metric, such as "Most Wins" or "Highest Health."
  

Prerequisites

On the eve of you start creating your leaderboard, make accurate you have the following:

• 
  
• A Roblox account and a match plan in Studio.
  
• Basic discernment of Lua scripting in Roblox.
  
• Experience with the Roblox Studio editor.
  
• Access to the Roblox API or Village Scripting (if you're using a municipal arrange).
  

Step 1: Invent a Leaderboard in the Roblox Server

To produce a leaderboard, we necessity to smoke the Roblox API. The most commonly acclimatized mothball inasmuch as this is RBXServerStorage, which allows you to accumulation data that is open across all players.

Creating the Leaderboard Table

We'll design a leaderboard provender in RbxServerStorage. This choice work as a leading location allowing for regarding storing each sportswoman's cut or other metric.

To fashion this, set to RbxServerStorage, right-click, and hand-pick "Untrodden Folder". Rename it to "Leaderboard".

Creating the Leaderboard Script

In the "Leaderboard" folder, contrive a fresh script. This script will be responsible as a remedy for storing and retrieving player scores.

-- leaderboard_script.lua
townswoman Leaderboard = {}
shire leaderboardFolder = game:GetService("ServerStorage"):WaitForChild("Leaderboard")

mission Leaderboard.SetScore(playerName, numbers)
close by playerData = leaderboardFolder:FindFirstChild(playerName)
if not playerData then
playerData = Instance.new("Folder")
playerData.Name = playerName
leaderboardFolder:WaitForChild(playerName):WaitForChild("Mark")
playerData:WaitForChild("Army"):WriteNumber(hordes)
else
playerData.Score = score
death
wind-up

event Leaderboard.GetScore(playerName)
local playerData = leaderboardFolder:FindFirstChild(playerName)
if playerData then
return playerData.Score
else
yield 0
undecided
end

return Leaderboard

This script defines two functions:
- SetScore: Stores a competitor's score.
- GetScore: Retrieves a player's score.

Step 2: Produce a Leaderboard in the Roblox Patron (Limited Order)

In the client, we prerequisite to access the leaderboard data. This is typically done using a specific libretto that connects to the server-side script.

Connecting to the Server-Side Leaderboard

We'll originate a shire script in the "LocalScript" folder of your game. This script wish entitle the functions from the server-side leaderboard script.

-- patient_leaderboard_script.lua
limited leaderboard = coerce(match:GetService("ServerStorage"):WaitForChild("Leaderboard"))

county playerName = game.Players.LocalPlayer.Name

peculiar banquet updateScore(avenge)
local currentScore = leaderboard.GetScore(playerName)
if currentScore < score then
        leaderboard.SetScore(playerName, reason)
    end
unceasingly

-- Standard: Update numbers when a trouper wins a rounded off
updateScore(100)

This order uses the server-side leaderboard functions to update the player's score. You can standing by this affair whenever you want to shadow a total, such:
- When a especially bettor completes a level.
- When they achieve first place in a round.
- When they execute a certain goal.

Step 3: Displaying the Leaderboard in the Game

At the present time that we procure the data stored, we need to demonstrate it. You can do this sooner than creating a leaderboard UI (UserInterface) in your contest and updating it each frame.

Creating the Leaderboard UI

In Roblox Studio, initiate a new "ScreenGui" and continue a "TextFrame" or "ScrollingPanel" to spectacle the leaderboard. You can also use "TextLabel" objects for each entry.

Here is an example of how you mightiness update the leaderboard each frame:

-- leaderboard_ui_script.lua
native Leaderboard = require(business:GetService("ServerStorage"):WaitForChild("Leaderboard"))

shire ui = game.Players.LocalPlayer:WaitForChild("PlayerGui"):WaitForChild("LeaderboardUI")

district playerList = ui:FindFirstChild("PlayerList")
if not playerList then
playerList = Instance.new("Folder")
playerList.Name = "PlayerList"
ui:WaitForChild("PlayerList"):WaitForChild("PlayerList")
end

tourney:GetService("RunService").Heartbeat:Rivet(reception()
local players = game.Players:GetPlayers()
townswoman sortedPlayers = {}
owing i, speculator in ipairs(players) do
county respect = player.Name
town score = Leaderboard.GetScore(name)
table.insert(sortedPlayers,  Pre-eminence = name, Coveys = score )
purpose

-- Lot through mark descending
table.sort(sortedPlayers, concern(a, b)
return a.Score > b.Score
consequence)

-- Definite the list
in behalf of i = 1, #playerList:GetChildren() do
townswoman youngster = playerList:GetChild(i)
if child:IsA("TextLabel") then
babe:Destroy()
intention
end

-- Sum modish players
in return i, playerData in ipairs(sortedPlayers) do
local textLabel = Instance.new("TextLabel")
textLabel.Text = string.format("%s - %d", playerData.Name, playerData.Score)
textLabel.Size = UDim2.new(1, 0, 0.1, 0)
textLabel.Position = UDim2.new(0, 0, (i-1)*0.1, 0)
textLabel.Parent = playerList
ending
extinguish)

This libretto will:
- Retrieve all players and their scores.
- Subspecies them by means of short in descending order.
- Starkly the leaderboard UI each frame.
- Supplement modern entries to display the present a-one players.

Step 4: Testing the Leaderboard

Before all things is set up, test your leaderboard by way of:

1. 
   
2. Running your occupation in Roblox Studio.
   
3. Playing as multiple players and changing scores to envision if they are recorded correctly.
   
4. Checking the leaderboard UI to make sure it updates in real-time.
   

Optional: Adding a Leaderboard in the Roblox Dashboard

If you be your leaderboard to be get-at-able through the Roblox dashboard, you can make use of the RankingSystemService.

Using RankingSystemService

The RankingSystemService allows you to track contestant rankings based on scores. This is helpful in return competitive games.

-- ranking_system_script.lua
village RS = stratagem:GetService("RankingSystemService")

local function updateRanking(playerName, groove)
provincial ranking = RS:CreateRanking("Archery nock", "Entertainer")
ranking:SetValue(playerName, herds)
point

updateRanking("Player1", 100)

This create creates a ranking pattern on "Be successful" and sets the value in search a player.

Conclusion

Creating a leaderboard in Roblox is a cyclopean way to go on increase competitive elements to your game. Beside using scripting, you can track scores, rankings, or other metrics and display them in real-time. This supervise has provided you with the demanded steps to create a basic leaderboard using both server-side and client-side scripts.

Final Thoughts

With routine, you can expand your leaderboard system to comprise more features such as:
- Leaderboard rankings based on multiple metrics.
- Routine UI fitting for displaying the leaderboard.
- Leaderboard perseverance across sessions.
- Leaderboard synchronization between players.

• 
  
• Explore advanced scripting techniques to better performance.
  
• Learn how to put together with the Roblox API as a service to external information retrieval.
