If you are tired of trolls or rule-breakers ruining the experience for everyone else, setting up a reliable roblox kick system script is probably one of the most important things you'll do for your game. It's one of those basic moderation tools that every developer needs sooner or later. Honestly, it doesn't matter if you're building a massive RPG or a tiny hangout spot—if you have more than two people in a server, someone is eventually going to try and push the boundaries.
Setting this up isn't as scary as it sounds. You don't need to be a Luau master to get a basic version running, but you do need to understand how the server and the client talk to each other. If you just put a kick button on a screen without the proper backend, you're basically giving every exploiter in the game a "kick anyone" button, which is the exact opposite of what we want.
How the Kick Function Actually Works
At its core, the logic is incredibly simple. Roblox provides a built-in method called :Kick(). When you call this on a player object, they are instantly disconnected from the server and shown a message. It looks something like this: player:Kick("You have been removed from the game.").
The real trick is making sure only the right people can trigger that line of code. In Roblox, anything that happens on the "Client" (the player's computer) can be messed with by hackers. This means your roblox kick system script needs to live on the "Server" (the Roblox cloud). If a moderator clicks a button on their screen, that button has to send a "request" to the server, and then the server decides if that person is actually allowed to kick people.
Setting Up the RemoteEvent
To bridge the gap between a moderator's UI and the server logic, we use something called a RemoteEvent. Think of it like a secure phone line. The moderator picks up the phone (clicks the button) and tells the server who needs to go.
- Go into your ReplicatedStorage.
- Create a new RemoteEvent and name it "KickPlayerEvent".
- Now, the server can "listen" for when this event is fired.
This is where most beginners trip up. They think they can just put the kick logic inside the button itself. If you do that, it won't work, or worse, it'll be a huge security hole. You always want the server to be the final judge.
Writing the Server-Side Script
Now we need a script in ServerScriptService to handle the actual removal. This is the "brain" of your roblox kick system script. We need to make sure the person firing the event is actually an admin. You can do this by checking their UserId or by checking if they belong to a specific group.
```lua local ReplicatedStorage = game:GetService("ReplicatedStorage") local KickEvent = ReplicatedStorage:WaitForChild("KickPlayerEvent")
-- List of people allowed to kick local admins = {1234567, 89101112} -- Replace with actual UserIds
KickEvent.OnServerEvent:Connect(function(player, targetPlayerName, reason) local isAdmin = false
-- Check if the person clicking the button is an admin for _, id in pairs(admins) do if player.UserId == id then isAdmin = true break end end if isAdmin then local target = game.Players:FindFirstChild(targetPlayerName) if target then target:Kick("\nModerator: " .. player.Name .. "\nReason: " .. reason) print(player.Name .. " kicked " .. targetPlayerName) end else -- If a non-admin tries to trigger this, maybe they're exploiting warn(player.Name .. " tried to use the kick system without permission!") end end) ```
By checking the isAdmin variable, you've just saved yourself a lot of headaches. Even if a script-kiddie figures out how to fire your RemoteEvent, the server will just look at their ID, see it's not on the list, and ignore the request.
Creating a Simple Moderator UI
You'll want a way for your admins to actually use the roblox kick system script without typing code into the console. A simple ScreenGui in StarterGui will do the trick. You just need a TextBox for the player's name, another TextBox for the reason, and a TextButton to submit it.
Inside the button, you'll need a LocalScript. It'll look something like this:
```lua local button = script.Parent local ReplicatedStorage = game:GetService("ReplicatedStorage") local KickEvent = ReplicatedStorage:WaitForChild("KickPlayerEvent")
button.MouseButton1Click:Connect(function() local targetName = script.Parent.Parent.NameBox.Text local reason = script.Parent.Parent.ReasonBox.Text
KickEvent:FireServer(targetName, reason) end) ```
Keep in mind that the LocalScript doesn't actually kick the person. It just sends the names to the server script we wrote earlier. The server does the heavy lifting.
Making the System More Professional
If you want your roblox kick system script to feel a bit more "pro," you can add features like autocomplete for player names or a dropdown menu. Typing out long usernames like "SuperCoolDeveloper_99" can be a pain, and if you make a typo, the script won't find the player.
A good way to handle this is to have a list that updates whenever someone joins or leaves. You could also add a "Reason" menu with presets like "Spamming," "Exploiting," or "Being Rude" so your moderators don't have to type the same thing over and over again.
Adding Discord Webhooks for Logging
One thing I always recommend is logging every kick. If a moderator starts abusing their power, you'll want to know about it. You can use HttpService to send a message to a Discord channel every time the kick script is triggered. It helps keep everyone accountable. Just be careful not to spam the webhook, or Discord might temporarily block your game's requests.
Handling Errors Gracefully
What happens if the player leaves the game right before the moderator hits the "Kick" button? Your script might throw an error because it's looking for a player that doesn't exist anymore. Using FindFirstChild is a great way to prevent this, as we did in the server script above. It checks if the player is actually there before trying to call the kick function. If it's nil, the script just doesn't do anything, and the game keeps running smoothly.
Why a Kick System Isn't a Ban System
It's important to remember that a kick is just a temporary "get out." The player can just click "Reconnect" and come right back in. If you're dealing with a serious exploiter, a roblox kick system script is really just a stopgap measure.
For more permanent solutions, you'd want to look into DataStores to create a ban system. A ban system essentially "kicks" the player every single time they try to join the game by checking their UserId against a saved list of banned players. But honestly, for most day-to-day moderation, a quick kick is enough to stop someone from being annoying in the moment.
Final Thoughts on Moderation Tools
Building your own tools is part of what makes Roblox development so rewarding. Sure, you could go to the Toolbox and grab a random "Admin Suite," but those often come with backdoors or bloated code that slows down your game. When you write your own roblox kick system script, you know exactly how it works, you know it's secure, and you can customize it however you want.
Just remember the golden rule of Roblox scripting: Never trust the client. As long as you keep your security checks on the server, your moderation tools will be a solid defense against whatever the internet throws at your game. Happy developing!
