JMonkeyEngine In game multiplayer chat

Not sure if this it the right section, if not could someone please move it?

I am creating a multiplayer FPS game. I have most of the functionality in the game working with players running around over a network, but I am stuck on how I would do an in game chat, I have lobbies in which players can communicate, but now I would like it so that during the game they can press a key and can start typing and send messages.

Btw I am using JME3

Any ideas would be helpful :slight_smile:
