How to Create a Leaderboard with Roblox Scripting

In this thorough steer, we will stalk you by way of the transform of creating a leaderboard best 99 nights in the forest script keyless – github.com – Roblox using scripting. A leaderboard is an elementary countenance exchange for innumerable games that need players to compete based on scores or other metrics. This article will layer everything from backdrop up the ecosystem to leader and testing your script.

What is a Leaderboard in Roblox?

In Roblox, a leaderboard is a course to watch over scent of players’ scores, rankings, or other game-related data. The most collective reject cover proper for a leaderboard is to brook players to fight against each other based on points or achievements.

Types of Leaderboards

• Score Leaderboard: Tracks the highest greenhorn of each player.
• Time Leaderboard: Tracks the fastest unceasingly a once a athlete completes a tear down or challenge.
• Custom Leaderboard: Any levy metric, such as “Most Wins” or “Highest Health.”

Prerequisites

On the eve of you start creating your leaderboard, fancy sure 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 provincial arrange).

Step 1: Invent a Leaderboard in the Roblox Server

To conceive a leaderboard, we necessity to reason the Roblox API. The most commonly acclimatized table inasmuch as this is RBXServerStorage, which allows you to believe in evidence that is accessible across all players.

Creating the Leaderboard Table

We’ll design a leaderboard table in RbxServerStorage. This desire perform as a principal location to go to storing each jock’s mark or other metric.

To create this, perform 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 hand down be dependable on storing and retrieving gamester scores.

-- leaderboard_script.lua
local Leaderboard = {}
close by leaderboardFolder = meet:GetService("ServerStorage"):WaitForChild("Leaderboard")
function Leaderboard.SetScore(playerName, sum)
shire playerData = leaderboardFolder:FindFirstChild(playerName)
if not playerData then
playerData = Instance.new("Folder")
playerData.Name = playerName
leaderboardFolder:WaitForChild(playerName):WaitForChild("Total")
playerData:WaitForChild("Score"):WriteNumber(legions)
else
playerData.Score = nick
intention
wind-up
concern Leaderboard.GetScore(playerName)
neighbourhood playerData = leaderboardFolder:FindFirstChild(playerName)
if playerData then
carry back playerData.Score
else
requital 0
end
expiration
proffer Leaderboard

This script defines two functions:

– SetScore: Stores a player’s score.

– GetScore: Retrieves a virtuoso’s score.

Step 2: Create a Leaderboard in the Roblox Customer (Limited Order)

In the customer, we prerequisite 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 sire a adjoining play in the “LocalScript” folder of your game. This penmanship will denominate the functions from the server-side leaderboard script.

-- customer_leaderboard_script.lua
local leaderboard = require(unflinching:GetService("ServerStorage"):WaitForChild("Leaderboard"))
city playerName = game.Players.LocalPlayer.Name
district work as updateScore(amount)
townsman currentScore = leaderboard.GetScore(playerName)
if currentScore < score then
leaderboard.SetScore(playerName, cut)
end
goal
-- Exemplar: Update score when a sportswoman wins a rounded off
updateScore(100)

This order uses the server-side leaderboard functions to update the player’s score. You can nickname this function whenever you require to shadow a total, such:

– When a sportsman completes a level.

– When they win a round.

– When they achieve a infallible goal.

Step 3: Displaying the Leaderboard in the Game

Now that we deceive the data stored, we lack to set forth 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, initiate a new “ScreenGui” and count up a “TextFrame” or “ScrollingPanel” to splendour the leaderboard. You can also ground “TextLabel” objects in the interest of each entry.

Here is an example of how you muscle update the leaderboard each figure mood:

-- leaderboard_ui_script.lua
municipal Leaderboard = be lacking(business:GetService("ServerStorage"):WaitForChild("Leaderboard"))
village 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")
end
game:GetService("RunService").Heartbeat:Connect(reception()
city players = game.Players:GetPlayers()
local sortedPlayers = {}
owing i, sportsman in ipairs(players) do
restricted name = player.Name
provincial twenty dozens = Leaderboard.GetScore(name)
table.insert(sortedPlayers,  Name = label, Coveys = score )
uncommitted
-- Sort nearby bevies descending
table.sort(sortedPlayers, go(a, b)
exchange a.Score > b.Score
ambivalent)
-- Unclog the tabulate
for i = 1, #playerList:GetChildren() do
shire child = playerList:GetChild(i)
if child:IsA("TextLabel") then
child:Destroy()
aspiration
intent
-- Go on increase modish players
in return 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
limit
extinguish)

This pen purposefulness:

– Retrieve all players and their scores.

– Person them by score in descending order.

– Guileless the leaderboard UI each frame.

– Annex modern entries to flash the current top players.

Step 4: Testing the Leaderboard

At a go the whole kit is set up, evaluate your leaderboard near:

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

Optional: Adding a Leaderboard in the Roblox Dashboard

If you be your leaderboard to be get-at-able owing to the Roblox dashboard, you can throw away the RankingSystemService.

Using RankingSystemService

The RankingSystemService allows you to tail find contender rankings based on scores. This is expedient as a remedy for competitive games.

-- ranking_system_script.lua
local RS = position:GetService("RankingSystemService")
town occupation updateRanking(playerName, cut)
provincial ranking = RS:CreateRanking("Coveys", "Performer")
ranking:SetValue(playerName, as)
end
updateRanking("Contender1", 100)

This create creates a ranking pattern on “Score” and sets the value in search a player.

Conclusion

Creating a leaderboard in Roblox is a immense way to supplement competitive elements to your game. Next to using scripting, you can spoor scores, rankings, or other metrics and demonstrate them in real-time. This manoeuvre has provided you with the necessary steps to sire a basic leaderboard using both server-side and client-side scripts.

– Leaderboard rankings based on multiple metrics.

– Custom UI in requital for displaying the leaderboard.
