Building Multiplayer Games with Phoenix and Phaser
summary
Live code shows Phoenix channels and Phaser (Pixi rendering) wired over WebSockets to sync a draggable “hello world” text, then evolve into per-player GenServer processes and supervision trees so each character is a server-side process. Demos reach 60fps with many sprites but reveal a scaling fault where 500 clients flood the network using naive broadcasts; switching to broadcast_from and considering a server pulse/batch update fixes echoes and reduces messages. Several multiplayer demos (rock paper scissors, snake, dots) and code on Github ktec are provided.
