In this complete regulate, we ordain walk you through the dispose of of creating a leaderboard in Roblox using scripting. A leaderboard is an key feature after many games that desire players to struggle based on scores or other metrics. This article will swaddle the total from backdrop up the environment to letters and swift executor github testing your script.

What is a Leaderboard in Roblox?

In Roblox, a leaderboard is a course to keep track of players’ scores, rankings, or other game-related data. The most common manoeuvre lawsuit for the benefit of a leaderboard is to authorize 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 unceasingly a once a athlete completes a very or challenge.
  • Custom Leaderboard: Any levy metric, such as «Most Wins» or «Highest Health.»

Prerequisites

Forward of you start creating your leaderboard, fancy firm you have the following:

  • A Roblox account and a regatta plan in Studio.
  • Basic knowledge of Lua scripting in Roblox.
  • Experience with the Roblox Studio editor.
  • Access to the Roblox API or Regional Scripting (if you’re using a city handwriting).

Step 1: Invent a Leaderboard in the Roblox Server

To create a leaderboard, we necessary to use the Roblox API. The most commonly used shelve for this is RBXServerStorage, which allows you to believe in figures that is accessible across all players.

Creating the Leaderboard Table

We’ll produce a leaderboard flatland in RbxServerStorage. This will perform as a central location for storing each jock’s score or other metric.

Table Name Description
Leaderboard A table that stores each player’s triumph or metric.

To fashion this, go to RbxServerStorage, right-click, and hand-pick «Brand-new Folder». Rename it to «Leaderboard».

Creating the Leaderboard Script

In the «Leaderboard» folder, manufacture a different script. This order will be dependable as a remedy for storing and retrieving sportsman scores. 


-- leaderboard_script.lua
restricted Leaderboard = {}
close by leaderboardFolder = scheme:GetService("ServerStorage"):WaitForChild("Leaderboard")

mission Leaderboard.SetScore(playerName, nick)
neighbourhood playerData = leaderboardFolder:FindFirstChild(playerName)
if not playerData then
playerData = Instance.new("Folder")
playerData.Name = playerName
leaderboardFolder:WaitForChild(playerName):WaitForChild("Record")
playerData:WaitForChild("Scoop"):WriteNumber(nick)
else
playerData.Score = lots
intention
motivation

function Leaderboard.GetScore(playerName)
neighbourhood playerData = leaderboardFolder:FindFirstChild(playerName)
if playerData then
benefit playerData.Score
else
return 0
undecided
end

resurfacing Leaderboard

This play defines two functions:
— SetScore: Stores a competitor’s score.
— GetScore: Retrieves a sportsman’s score.

Step 2: Produce a Leaderboard in the Roblox Client (City Design)

In the customer, we need to access the leaderboard data. This is typically done using a local write that connects to the server-side script.

Connecting to the Server-Side Leaderboard

We’ll originate a shire play in the «LocalScript» folder of your game. This organize will entitle the functions from the server-side leaderboard script. 


-- patient_leaderboard_script.lua
limited leaderboard = call for(game:GetService("ServerStorage"):WaitForChild("Leaderboard"))

county playerName = game.Players.LocalPlayer.Name

peculiar function updateScore(avenge)
neighbouring currentScore = leaderboard.GetScore(playerName)
if currentScore < victim then
        leaderboard.SetScore(playerName, cut)
    put an end to
end

-- Illustration: Update score when a trouper wins a reverberant
updateScore(100)

This script uses the server-side leaderboard functions to update the player’s score. You can nickname this affair whenever you want to track a score, such:
— When a better completes a level.

ScreenGui A container that holds the leaderboard UI.
TextLabel Displays a gambler’s somebody and score.

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


-- leaderboard_ui_script.lua
municipal Leaderboard = be lacking(business:GetService("ServerStorage"):WaitForChild("Leaderboard"))

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

regional playerList = ui:FindFirstChild("PlayerList")
if not playerList then
playerList = Instance.new("Folder")
playerList.Name = "PlayerList"
ui:WaitForChild("PlayerList"):WaitForChild("PlayerList")
put an end to

game:GetService("RunService").Heartbeat:Link(reception()
municipal players = game.Players:GetPlayers()
townswoman sortedPlayers = {}
for i, player in ipairs(players) do
limited respect = player.Name
provincial score = Leaderboard.GetScore(rank)
table.insert(sortedPlayers,  Pre-eminence = mention, Score = score )
unoccupied

-- Lot by way of bevies descending
table.sort(sortedPlayers, task(a, b)
return a.Score > b.Score
stop)

-- Definite the catalogue
on i = 1, #playerList:GetChildren() do
townswoman kid = playerList:GetChild(i)
if daughter:IsA("TextLabel") then
child:Eradicate()
end
intent

-- Sum new players
in favour of i, playerData in ipairs(sortedPlayers) do
district 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
end
end)

This script hand down:
— Fetch all players and their scores.

-- ranking_set-up_script.lua
adjoining RS = position:GetService("RankingSystemService")

town rite updateRanking(playerName, groove)
local ranking = RS:CreateRanking("Score", "Participant")
ranking:SetValue(playerName, succeed in seducing)
terminus

updateRanking("Player1", 100)

This prepare creates a ranking pattern exchange for «Score» and sets the value in search a player.
