These applications constitute a prototype for a multiplayer, 2D world with chat. We use a client/server approach, such that the server can be hosted on a cloud provider and run in headless mode.
Each player has the ability to move around, in addition to being able to chat.
We shamelessly stole the bulk of this project from this client-server example. Thank you to menip for providing this code!
We drew further inspiration from this chat example. Thank you!
In addition to the official multiplayer docs, we found this cheatsheet helpful.
