Pong Online

Online Pong game created using Elixir and Phoenix LiveView. Demo at: pongo.gigalixirapp.com

How does it work?

• Each Player process registers itself with the MatchMaker process during mount.
• The MatchMaker creates a Match process with references to 2 Player processes.
• The Match process receives any input from the players and advances the Game state 15 times per second.
• After each update, the Game state is sent to each player (the state is inverted for the top player, so both have the same view of the board).
• The state is rendered client-side in a canvas. The client is always a step behind the server and interpolates between the previous state and the current one.
