📌 The Process

I wanted a way to send messages to everyone in my game, but the normal chat wasn’t suitable because I wanted messages to be sent across every server.

I started simple by making a GUI that prints what the player types when they press the send button.

After that, I changed it so instead of printing, it creates a GUI at the top of the screen showing the message with a colored name.

Then I moved on to the server system. I first created a table where I could add admins who are allowed to use the system.

After that, I used MessagingService to send the message to every server.

When each server receives the message, it sends it to all players and updates the GUI.

After a few bug fixes, the system was finished!
