Multiplayer Pac-Man with RSocket - Oleh Dokuka

Video from Devoxx Poland 2019. One of the challenging aspects of building modern games is making the multiplayer one. Can we use HTTP there? We can, but we will not get a real-time game. Can we use WebSockets / TCP? Of course, we can and we should! However, developing API on top of WebSocket is another challenge that no one wants to solve, but everyone does. Existing libraries do not give us a required variety of communication models. Today we will show you the way to tackle this - using RSocket. RSocket is an application protocol that makes developing any networked application as easy as pie. To prove that, we are going to build a multiplayer Pac-Man, and during the process compare different ways of making a multiplayer game.
