If you're trying to keep your players informed without having to manually message everyone, setting up a solid roblox announcement script is the way to go. It's one of those small touches that makes a game feel "finished." Whether you're warning people about an upcoming server shutdown, announcing a new limited-time event, or just saying hi, having a system in place is way better than just hoping people check your Discord or Twitter.
In this breakdown, we're going to look at a few different ways to handle this. We'll start with the really simple stuff—like basic chat messages—and then move into the fancy custom UI stuff that pops up on everyone's screen.
Why Bother with a Custom System?
You might be thinking, "Can't I just use the default server message?" Well, sure, but it's kind of boring. It gets lost in the chat, especially if you have a bunch of players talking at once. A custom roblox announcement script gives you control over the look, the sound, and even how long the message stays on the screen.
Think about the big games like Pet Simulator or Blox Fruits. When there's an update or a major event, they don't just send a tiny gray text in the chat. They use big, bold banners or custom UI elements that grab your attention immediately. That's the kind of vibe we're going for here.
The "Old Reliable" Chat Method
The quickest way to get a roblox announcement script running is by using the system chat. This is great for low-stakes info, like "Player123 has joined the server." It doesn't interrupt gameplay, but it's still official.
To do this, you use a function called SetCore. Here's the catch: SetCore only works on the client side (in a LocalScript). So, if you want to send a message from the server to everyone, you'll need a RemoteEvent.
- Create a RemoteEvent in
ReplicatedStorageand name itAnnouncementEvent. - In a LocalScript (put this in
StarterPlayerScripts), listen for that event. - When the event fires, use
StarterGui:SetCore("ChatMakeSystemMessage", )to show the text.
It's a bit of a workaround because you have to bounce from the server to the client, but it's a very clean way to keep things integrated with the existing UI.
Building a Custom UI Announcement
If you want something that really pops, you've got to build a custom GUI. This is where most developers spend their time. You'll want a ScreenGui in StarterGui, and inside that, a Frame that sits at the top of the screen.
Inside the frame, add a TextLabel. This is where your roblox announcement script will push the actual words. Don't forget to set the Visible property of the main frame to false by default. You only want it to appear when there's actually something to say.
Making it Look Smooth with Tweens
Static UI is okay, but it looks a bit "2012 Roblox." To make it feel modern, you should use TweenService. Instead of the announcement just snapping into existence, have it slide down from the top of the screen or fade in gracefully.
When the server sends the signal, the LocalScript should catch it, set the text, and then play a tween to move the frame from Position (0.5, 0, -0.2, 0) to Position (0.5, 0, 0.1, 0). Hold it there for five or ten seconds, then tween it back up. It's a simple change, but it makes your game look ten times more professional.
Taking it Global with MessagingService
Now, here's where things get interesting. Most scripts only talk to the players currently in one server. But what if your game is huge and has fifty different servers running? If you want to announce something to everyone at the exact same time, you need MessagingService.
MessagingService is basically Roblox's way of letting different servers "talk" to each other. You can "Publish" a message to a specific topic, and every other server "Subscribes" to that topic. When you hit that "Send" button on your admin panel, MessagingService broadcasts that data across the entire Roblox cloud.
This is the backbone of any serious roblox announcement script. Without it, you'd have to join every single server manually to tell people the game is updating. Nobody has time for that.
Creating an Admin Control Panel
You don't want to have to jump into Roblox Studio and edit scripts every time you want to say something. You need an in-game way to trigger these announcements.
Usually, this means creating a small, hidden UI that only players with a certain UserId or a specific Group Rank can see. This panel should have a TextBox for the message and a "Send" button.
When you click "Send," the client sends that text to the server via a RemoteEvent. Crucial Tip: Always verify on the server that the player sending the message actually has permission. If you don't check their UserId on the server-side, a lucky exploiter could start sending "Subscribe to my channel" messages to every single person playing your game. Not a great look.
Filtering Your Text
Roblox is super strict about chat filtering, and for good reason. If your roblox announcement script displays unfiltered text, you're asking for a ban.
Before you broadcast the message to everyone, you must run it through TextService:FilterStringAsync(). This ensures that if you accidentally (or intentionally) type something that triggers the filter, it comes out as hashtags rather than getting you in trouble with the moderation team. It's a bit of extra code, but it's non-negotiable for any public-facing game.
Adding Sound Effects
Never underestimate the power of a good "ding." When an announcement pops up, play a short, clean sound effect. Something like a UI click or a soft chime. It cues the player to look up from what they're doing.
Just make sure it's not too loud or annoying. If you're sending multiple announcements in a row, a piercing sound will just make players want to leave. Keep it subtle, keep it professional.
Handling Long Messages
Sometimes you have a lot to say, and it won't fit on one line. You have two choices here: you can make the TextLabel wrap the text, or you can make the UI expand.
Most people prefer a scrolling marquee style or just a simple box that grows based on the content. If you use UIListLayout and set the AutomaticSize property on your frame, Roblox will actually do most of the heavy lifting for you. It'll resize the box to fit whatever text you throw at it.
Troubleshooting Common Issues
If your roblox announcement script isn't working, it's usually one of three things: 1. The RemoteEvent is named wrong. Double-check your spelling! "AnnouncementEvent" is not the same as "AnnouncmentEvent." 2. The LocalScript is in the wrong place. LocalScripts don't run in Workspace. Keep them in StarterPlayerScripts or inside the ScreenGui itself. 3. Filtering errors. If TextService fails, the whole script might hang. Wrap your filtering logic in a pcall() (protected call) so that even if the Roblox filtering API is having a bad day, your game doesn't crash.
Wrapping Things Up
Getting a roblox announcement script up and running isn't just about the code; it's about how you communicate with your community. It builds trust when players see that the developer is active and keeping them updated.
Start with a simple chat message if you're just learning the ropes. Once you're comfortable with RemoteEvents and GUI manipulation, try your hand at the MessagingService stuff. It feels pretty cool to send a message from one server and realize that thousands of people are seeing it across the entire platform at the same time.
Just remember to keep the UI clean, filter your strings, and don't spam the "Send" button too hard. Happy devving!
