A roblox custom announcement system script is one of those essential tools that can take a basic game and make it feel like a polished, living community. If you've ever spent time in a massive RPG or a popular hang-out game, you've definitely seen those sleek notifications sliding across the top of the screen telling you that an event is starting or that the servers are about to go down for an update. It's way more effective than just shouting in the chat where your message gets buried under a mountain of "pls donate" and "ABC for a mom."
Setting up your own system isn't just about showing off; it's about communication. Whether you want to announce a new skin drop, give a shout-out to a top player, or just warn everyone that you're about to reboot the server, having a dedicated UI for it makes your game feel professional. Plus, let's be real—players are way more likely to pay attention to a nicely animated banner than a line of text in the chat box.
Why You Shouldn't Just Use the Default Chat
You might be thinking, "Can't I just use StarterGui:SetCore to send a notification?" Well, sure, you could. But those default Roblox notifications are pretty limited. They look the same in every game, you can't really control how long they stay on the screen, and you definitely can't style them to match your game's unique aesthetic.
When you build a roblox custom announcement system script, you have total control. You can choose the fonts, the colors, the sounds, and even the way the message enters the screen. Want it to slide from the left? Easy. Want it to fade in and pulse? You can do that too. It creates a cohesive experience for the player, making the announcement feel like a part of the world rather than a system pop-up.
The Core Logic Behind the Script
Before you start dragging frames and labels into your StarterGui, it's worth understanding how the plumbing works. A good announcement system usually relies on three main parts: an admin panel (or a command system), a RemoteEvent, and the client-side UI script.
The logic is pretty straightforward: 1. The Trigger: An authorized user (usually you or your moderators) types a message into a text box or a command. 2. The Server Script: This script checks if the person has permission to send announcements. We don't want random players taking over the screen. 3. The RemoteEvent: Once the server verifies the admin, it "fires" a RemoteEvent to all the players currently in the game. 4. The Client Script: Every player's game client receives that event and triggers the UI animation, displaying the message.
It sounds like a lot of steps, but it's actually the safest and most efficient way to handle it. You never want the client to have the power to tell everyone else what to see without the server checking in first.
Building the UI (The Fun Part)
This is where you get to be creative. Most developers go for a bar at the top of the screen. When you're setting this up in Roblox Studio, make sure you use UISizeConstraint and UIAspectRatioConstraint. There's nothing worse than an announcement that looks great on your monitor but covers 90% of the screen for someone playing on a phone.
I'd recommend keeping it simple. A semi-transparent black or dark blue background with a clean, white font like "Montserrat" or "Gotham" usually looks the best. If you want to get fancy, you can add a small icon next to the text—like a megaphone or a "!" sign—to draw the eye.
Don't forget the TweenService. A static box just appearing out of thin air feels a bit janky. Having it slide down from the top of the screen or slowly fade in makes the whole experience feel much more premium. Even a 0.5-second tween makes a world of difference.
Handling Security and Filtering
This is the part that a lot of people skip, and it's arguably the most important. If you're making a roblox custom announcement system script, you must use TextService:FilterStringAsync.
Roblox is very strict about chat filtering. If you allow an admin to send an unfiltered message to everyone in the game, and that message contains something inappropriate, your game (and possibly your account) could be moderated. It doesn't matter if you're the only one who has access to the admin panel; accidents happen, and hackers sometimes find ways to trigger RemoteEvents.
Always filter the text on the server before you send it out to the clients. It takes an extra minute to script, but it saves you a massive headache down the road. It's also a good idea to "Sanitize" the input—basically making sure the string isn't too long so it doesn't break your UI or lag the server.
Making It Admin-Only
You definitely don't want every player in your game sending global announcements. You can restrict the system by checking the player's UserID or their Rank in a specific Group.
If you're using a group-based system, you'd use Player:GetRankInGroup(yourGroupID). If their rank is high enough, the server script will allow the RemoteEvent to fire. If a random player tries to mess with the RemoteEvent via an exploit, the server will just ignore them because their rank isn't high enough. It's a simple layer of security that keeps your game from turning into total chaos.
Advanced Features to Consider
Once you have the basic "Admin types message -> Everyone sees message" flow working, you can start adding some cool bells and whistles.
Timed Announcements
Instead of manually typing messages, you could have the script pull from a list of pre-written announcements. Maybe every 10 minutes, the game reminds players to join your Discord server or check out the latest update log. This keeps the game feeling active even when you're not there to moderate it.
Sound Effects
Adding a subtle "ping" or "notification" sound when the announcement appears is a great way to grab attention. Just make sure the sound isn't too loud or annoying. A short, high-pitched chime usually does the trick.
Color Coding
You could set up the script to handle different types of announcements. A "General" message might be blue, an "Event" might be gold, and a "Server Maintenance" alert might be red. You can pass the color as a variable through the RemoteEvent so the client-side UI knows exactly how to style the frame.
Common Mistakes to Avoid
I've seen a lot of developers struggle with their first roblox custom announcement system script. One of the biggest mistakes is not accounting for players who join after an announcement has been sent. If you send a "Global Event Started" message but someone joins 10 seconds later, they won't see it.
To fix this, you can store the current announcement in a StringValue inside ReplicatedStorage. When a new player joins, their client script can check if that value is empty. If it's not, it can display the message immediately.
Another pitfall is forgetting about the "ZIndex." You want your announcement to be on top of everything else—buttons, health bars, inventory slots. Set the ZIndex of your announcement ScreenGui to a high number like 10 or 100 to make sure it doesn't get hidden behind other UI elements.
Final Thoughts
At the end of the day, a roblox custom announcement system script is a small addition that makes a huge impact. It's about more than just showing text; it's about branding and communication. It tells your players that you care about their experience and that the game is actively being managed.
The beauty of Roblox is how much freedom you have. You can start with a tiny script and eventually grow it into a massive notification system that handles everything from player achievements to world-ending events. Just remember to keep your code clean, your UI responsive, and for the love of all things holy, don't forget to filter your strings!
Once you get it up and running, you'll wonder how you ever managed your game without one. It's one of those "quality of life" upgrades that genuinely makes the development process more rewarding. Happy scripting!
