One of the challenging aspects of building modern games is making it multiplayer especially when it comes to choosing transport among the variety of network protocols and their limitations. Performance, stability, and simplicity in development, - can we have them all at once? 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 the game.
