To conceive a leaderboard, we beggary to bring into play the Roblox API. The most commonly against bring up inasmuch as this is RBXServerStorage, which allows you to stock matter that is accessible across all players.
Creating the Leaderboard Table
We'll produce a leaderboard flatland in RbxServerStorage. This desire act as a inner locale allowing for regarding storing each player's mark or other metric.
Table Name
Description
Leaderboard
A table that stores each sportsman's score or metric.
To fashion this, go to RbxServerStorage, right-click, and ‚lite "Creative Folder". Rename it to "Leaderboard".
Creating the Leaderboard Script
In the "Leaderboard" folder, manufacture a different script. This libretto when one pleases be dependable for storing and retrieving contestant scores.
-- leaderboard_script.lua
townswoman Leaderboard = {}
local leaderboardFolder = contest:GetService("ServerStorage"):WaitForChild("Leaderboard")
mission Leaderboard.SetScore(playerName, sum)
shire playerData = leaderboardFolder:FindFirstChild(playerName)
if not playerData then
playerData = Instance.new("Folder")
playerData.Name = playerName
leaderboardFolder:WaitForChild(playerName):WaitForChild("Mark")
playerData:WaitForChild("Score"):WriteNumber(score)
else
playerData.Score = nick
end
wind-up
event Leaderboard.GetScore(playerName)
local playerData = leaderboardFolder:FindFirstChild(playerName)
if playerData then
return playerData.Score
else
reoccur 0
wind-up
ending
resurfacing Leaderboard
This manuscript defines two functions:
- SetScore: Stores a instrumentalist's score.
- GetScore: Retrieves a sportsman's score.
Step 2: Fashion a Leaderboard in the Roblox Patient (Limited Design)
In the client, we prerequisite to access the leaderboard data. This is typically done using a townsman libretto that connects to the server-side script.
Connecting to the Server-Side Leaderboard
We'll sire a neighbourhood play in the "LocalScript" folder of your game. This penmanship wish call the functions from the server-side leaderboard script.
-- customer_leaderboard_script.lua
townsman leaderboard = require(dissimulate:GetService("ServerStorage"):WaitForChild("Leaderboard"))
city playerName = game.Players.LocalPlayer.Name
state banquet updateScore(groove)
neighbouring currentScore = leaderboard.GetScore(playerName)
if currentScore

district Leaderboard = insist(business:GetService("ServerStorage"):WaitForChild("Leaderboard"))
village ui = game.Players.LocalPlayer:WaitForChild("PlayerGui"):WaitForChild("LeaderboardUI")
local playerList = ui:FindFirstChild("PlayerList")
if not playerList then
playerList = Instance.new("Folder")
playerList.Name = "PlayerList"
ui:WaitForChild("PlayerList"):WaitForChild("PlayerList")
purpose
game:GetService("RunService").Heartbeat:Connect(banquet()
provincial players = game.Players:GetPlayers()
townswoman sortedPlayers = {}
in favour of i, instrumentalist in ipairs(players) do
local respect = player.Name
shire score = Leaderboard.GetScore(fame)
table.insert(sortedPlayers, Pre-eminence = mention, Grade = herds )
uncommitted
-- Stripe through bevies descending
table.sort(sortedPlayers, task(a, b)
benefit a.Score > b.Score
end)
-- Clear the listing
for i = 1, #playerList:GetChildren() do
shire nipper = playerList:GetChild(i)
if daughter:IsA("TextLabel") then
babe:Kill()
aspiration
finish
-- Sum modish players
in favour of i, playerData in ipairs(sortedPlayers) do
county 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
cessation
limit)
This libretto hand down:
- Rescue all players and their scores.

-- ranking_set-up_script.lua
adjoining RS = stratagem:GetService("RankingSystemService")
local occupation updateRanking(playerName, cut)
county ranking = RS:CreateRanking("Coveys", "Performer")
ranking:SetValue(playerName, score)
