Multiplayer Pong

Multiplayer version of Pong that runs in your browser. See Game Networking Techniques, Explained with Pong.

I created it to learn about different networking techniques. It has three different modes.

• lockstep: The game does not proceed until both players have issued an action for the next frame (either move up, move down, or a non-move frame).
• terminal-client: All game logic is handled on the server. Clients send their moves to a server. The position of the paddles are set on the clients only after the server responds with their new positions.
• predictive-client: The client renders the local paddle's move immediately before sending its position to the server. The server issues a correction if the move was impossible.

Latency for each mode can be set in core/configjs. Lockstep mode only mimics a peer-to-peer connection, using a server to forward requests to each client.
