How to Make a Leaderboard with Roblox Scripting

In this thorough steer, we desire stalk you entirely the dispose of of creating a leaderboard in Roblox using scripting. A leaderboard is an principal countenance as a replacement for innumerable games that need players to compete based on scores or seliware executor download other metrics. This article wishes overspread the whole from habitat up the environment to letters and testing your script.

What is a Leaderboard in Roblox?

In Roblox, a leaderboard is a way to support spoor of players' scores, rankings, or other game-related data. The most collective manoeuvre lawsuit on a leaderboard is to brook players to vie against each other based on points or achievements.

Types of Leaderboards

• 
  
• Score Leaderboard: Tracks the highest grade of each player.
  
• Time Leaderboard: Tracks the fastest outdated a especially bettor completes a parallel or challenge.
  
• Custom Leaderboard: Any tradition metric, such as "Most Wins" or "Highest Health."
  

Prerequisites

In the past you start creating your leaderboard, make unfaltering you have the following:

• 
  
• A Roblox account and a regatta activity in Studio.
  
• Basic education of Lua scripting in Roblox.
  
• Experience with the Roblox Studio editor.
  
• Access to the Roblox API or Regional Scripting (if you're using a local calligraphy).
  

Step 1: Frame a Leaderboard in the Roblox Server

To create a leaderboard, we necessity to smoke the Roblox API. The most commonly hand-me-down mothball for this is RBXServerStorage, which allows you to stock evidence that is accessible across all players.

Creating the Leaderboard Table

We'll produce a leaderboard table in RbxServerStorage. This determination act as a leading locale to go to storing each performer's mark or other metric.

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

Creating the Leaderboard Script

In the "Leaderboard" folder, contrive a new script. This libretto hand down be chief after storing and retrieving sportsman scores.

-- leaderboard_script.lua
local Leaderboard = {}
specific leaderboardFolder = meet:GetService("ServerStorage"):WaitForChild("Leaderboard")

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

business Leaderboard.GetScore(playerName)
village playerData = leaderboardFolder:FindFirstChild(playerName)
if playerData then
render playerData.Score
else
reoccur 0
end
ruin

return Leaderboard

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

Step 2: Originate a Leaderboard in the Roblox Patient (Limited Order)

In the patient, we need to access the leaderboard data. This is typically done using a neighbouring book that connects to the server-side script.

Connecting to the Server-Side Leaderboard

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

-- client_leaderboard_script.lua
townsman leaderboard = coerce(unflinching:GetService("ServerStorage"):WaitForChild("Leaderboard"))

county playerName = game.Players.LocalPlayer.Name

state banquet updateScore(avenge)
local currentScore = leaderboard.GetScore(playerName)
if currentScore < grounds then
        leaderboard.SetScore(playerName, reason)
    motive
unceasingly

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

This pen uses the server-side leaderboard functions to update the musician's score. You can denominate this affair whenever you want to keep up with a bevies, such:
- When a especially bettor completes a level.
- When they induce a round.
- When they succeed in a undeniable goal.

Step 3: Displaying the Leaderboard in the Game

Age that we from the observations stored, we need to demonstrate it. You can do this sooner than creating a leaderboard UI (UserInterface) in your game and updating it each frame.

Creating the Leaderboard UI

In Roblox Studio, create a novel "ScreenGui" and sum a "TextFrame" or "ScrollingPanel" to splendour the leaderboard. You can also use "TextLabel" objects in support of each entry.

Here is an exempli gratia of how you muscle update the leaderboard each organization:

-- leaderboard_ui_script.lua
district Leaderboard = ask for(engagement:GetService("ServerStorage"):WaitForChild("Leaderboard"))

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

neighbouring 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:Rivet(reception()
provincial players = game.Players:GetPlayers()
regional sortedPlayers = {}
quest of i, player in ipairs(players) do
local name = player.Name
provincial twenty dozens = Leaderboard.GetScore(handle)
table.insert(sortedPlayers,  Name = renown, Score = stroke )
end

-- Sort by way of bevies descending
table.sort(sortedPlayers, concern(a, b)
exchange a.Score > b.Score
ambivalent)

-- Definite the listing
for the benefit of i = 1, #playerList:GetChildren() do
shire youngster = playerList:GetChild(i)
if child:IsA("TextLabel") then
boy:Stop()
intention
finish

-- Add unknown 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
cessation
put to death)

This penmanship purposefulness:
- Fetch all players and their scores.
- Sort them at hand score in descending order.
- Guileless the leaderboard UI each frame.
- Add modern entries to grandeur the contemporary ascend players.

Step 4: Testing the Leaderboard

Before the total is set up, assay your leaderboard sooner than:

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

Optional: Adding a Leaderboard in the Roblox Dashboard

If you lack your leaderboard to be open washing one's hands of the Roblox dashboard, you can make use of the RankingSystemService.

Using RankingSystemService

The RankingSystemService allows you to scent contestant rankings based on scores. This is expedient for competitive games.

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

local rite updateRanking(playerName, cut)
local ranking = RS:CreateRanking("Score", "Performer")
ranking:SetValue(playerName, herds)
intention

updateRanking("Contender1", 100)

This continuity creates a ranking system on "Score" and sets the value for a player.

Conclusion

Creating a leaderboard in Roblox is a immense feature to amplify competitive elements to your game. Next to using scripting, you can scent scores, rankings, or other metrics and advertise them in real-time. This guide has provided you with the compulsory steps to sire a basic leaderboard using both server-side and client-side scripts.
