Hi, I want to make a news feed for my game where I can just post there anything I need and everyone on the main menu will see it.
Sounds like you are talking about an online game. If so, you have a database of some kind, correct? So if you use MySQL/PHP you could create a ‘MainMenuInfo’ table and create a column with text that you can change. You could create 4 columns for example and have the latest news up top.
Over HTTP right? Blueprints don’t support HTTP by default, you either need to use C++ and HTTP APIs that UE4 provides there or use 3rd party plugin called VaRest (you might find other maybe, this one is most know). VaRest and UE4 APIs in C++ procides decoding so make your server output news in that format.
Best practice would be use of RSS, you would need XML decoding here, UE4 APIs has API to decode XML but i don’t know any Blueprint solution for that VaRest only support .
Other more simpler solution would be use of WebBrowser widget
