Okay, I'm sorry for asking this but please don't immediately close my question. I need some platform to start on for trying to make this. I see people do it all of the time in their games, but I am so pent up about it because I want to know how to do it! I'm not asking for a tutorial, just maybe some wiki links or some references. Thanks.
You would use a BillBoard Gui I believe. Try and being creative. Don't ask me for additional help learn by the scripting wiki and online tutorials.
I don't play Watch Dogs
