So uh i'm a Chief Developer in Atlas Corporation, and i just wanted to know, how can i make a overhead name for group only e.g : If you are in the Special Force group you have your overhead name as [CLASSIFIED] and if you are the normal infantry division youhave [Infantry] on your overhead name Anyone can help me?
To determine if a player is in a group, you would likely use Player:GetRankInGroup. This function returns a value between 0 - 255, 0 being not in the group.
As for the overhead name, this is not a request site, nor is it a site about GUIs. This is a site about obtaining help with existing scripts.
I would advise you to do a google search, or a couple google searches to find tutorials or something of a similar nature to learn about how you can accomplish the overhead GUI.
After my first google search for "overhead gui roblox", I found this video by AlvinBlox, a relatively famous Roblox scripting YouTuber.
