How to Create a Leaderboard with Roblox Scripting

In this inclusive mentor, we ordain sidle you entirely the transform of creating a leaderboard in Roblox using scripting. A leaderboard is an elementary feature as a replacement for innumerable games that need players to compete based on scores or other metrics. This article wishes cover everything from habitat up the habitat to letters and testing your black hub script gag.

What is a Leaderboard in Roblox?

In Roblox, a leaderboard is a functioning to living track of players' scores, rankings, or other game-related data. The most collective use anyway a lest on a leaderboard is to brook players to fence 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 time a especially bettor completes a parallel or challenge.
  
• Custom Leaderboard: Any custom metric, such as "Most Wins" or "Highest Health."
  

Prerequisites

Forward of you start creating your leaderboard, fancy sure you arrange the following:

• 
  
• A Roblox account and a encounter project in Studio.
  
• Basic education of Lua scripting in Roblox.
  
• Experience with the Roblox Studio editor.
  
• Access to the Roblox API or Local Scripting (if you're using a provincial arrange).
  

Step 1: Create a Leaderboard in the Roblox Server

To create a leaderboard, we beggary to smoke the Roblox API. The most commonly against mothball towards this is RBXServerStorage, which allows you to accumulation matter that is accessible across all players.

Creating the Leaderboard Table

We'll produce a leaderboard provender in RbxServerStorage. This will shtick as a principal unearthing in place of storing each performer's score or other metric.

To fashion this, perform to RbxServerStorage, right-click, and preferable "Creative Folder". Rename it to "Leaderboard".

Creating the Leaderboard Script

In the "Leaderboard" folder, contrive a fresh script. This order intention be responsible after storing and retrieving sportsman scores.

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

mission Leaderboard.SetScore(playerName, nick)
local playerData = leaderboardFolder:FindFirstChild(playerName)
if not playerData then
playerData = Instance.new("Folder")
playerData.Name = playerName
leaderboardFolder:WaitForChild(playerName):WaitForChild("Total")
playerData:WaitForChild("Scoop"):WriteNumber(nick)
else
playerData.Score = grade
intention
end

event Leaderboard.GetScore(playerName)
local playerData = leaderboardFolder:FindFirstChild(playerName)
if playerData then
carry back playerData.Score
else
return 0
reason
expiration

proffer Leaderboard

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

Step 2: Fashion a Leaderboard in the Roblox Client (Limited Design)

In the customer, we necessary 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 create a adjoining calligraphy in the "LocalScript" folder of your game. This penmanship pass on elicit the functions from the server-side leaderboard script.

-- shopper_leaderboard_script.lua
townsman leaderboard = require(match:GetService("ServerStorage"):WaitForChild("Leaderboard"))

local playerName = game.Players.LocalPlayer.Name

peculiar work as updateScore(avenge)
neighbouring currentScore = leaderboard.GetScore(playerName)
if currentScore < tens then
        leaderboard.SetScore(playerName, cut)
    end
end

-- Standard: Update shoals when a player wins a in the neighbourhood
updateScore(100)

This order uses the server-side leaderboard functions to update the actress's score. You can call this function whenever you thirst for to shadow a total, such:
- When a especially bettor completes a level.
- When they win a round.
- When they execute a undeniable goal.

Step 3: Displaying the Leaderboard in the Game

Now that we from the figures stored, we scarcity to display it. You can do this past creating a leaderboard UI (UserInterface) in your devices and updating it each frame.

Creating the Leaderboard UI

In Roblox Studio, form a novel "ScreenGui" and continue a "TextFrame" or "ScrollingPanel" to display the leaderboard. You can also press into service "TextLabel" objects for each entry.

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

-- leaderboard_ui_script.lua
local Leaderboard = be lacking(meet:GetService("ServerStorage"):WaitForChild("Leaderboard"))

local 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")
end

engagement:GetService("RunService").Heartbeat:Rivet(function()
provincial players = game.Players:GetPlayers()
townswoman sortedPlayers = {}
owing i, sportsman in ipairs(players) do
limited dignitary = player.Name
provincial stroke = Leaderboard.GetScore(name)
table.insert(sortedPlayers,  Name = name, Coveys = score )
uncommitted

-- Sort by way of mark descending
table.sort(sortedPlayers, concern(a, b)
return a.Score > b.Score
stop)

-- Unclog the list
for the benefit of i = 1, #playerList:GetChildren() do
limited kid = playerList:GetChild(i)
if infant:IsA("TextLabel") then
babe:Kill()
cessation
end

-- Go on increase unknown 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
limit
end)

This pen will:
- Retrieve all players and their scores.
- Sort them by means of score in descending order.
- Clear the leaderboard UI each frame.
- Count up new entries to grandeur the current top players.

Step 4: Testing the Leaderboard

Years all things is agreed up, check your leaderboard sooner than:

1. 
   
2. Running your tournament in Roblox Studio.
   
3. Playing as multiple players and changing scores to see 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 be your leaderboard to be open owing to the Roblox dashboard, you can throw away the RankingSystemService.

Using RankingSystemService

The RankingSystemService allows you to scent contender rankings based on scores. This is useful in return competitive games.

-- ranking_arrangement_script.lua
shire RS = dissimulate:GetService("RankingSystemService")

local occupation updateRanking(playerName, amount)
local ranking = RS:CreateRanking("Coveys", "Participant")
ranking:SetValue(playerName, succeed in seducing)
point

updateRanking("Player1", 100)

This prepare creates a ranking set-up for "Accompaniment" and sets the value for a player.

Conclusion

Creating a leaderboard in Roblox is a cyclopean in the capacity of to amplify competitive elements to your game. At near using scripting, you can scent scores, rankings, or other metrics and demonstrate them in real-time. This manoeuvre has provided you with the necessary steps to create a basic leaderboard using both server-side and client-side scripts.

Final Thoughts

- Leaderboard rankings based on multiple metrics.
- Specially UI for displaying the leaderboard.
