A simple version of the game of pong, entirely written in Go and running in the browser

An online, multiplayer version of the game of pong, entirely written in Go and compiled to webassembly.

Running live at https://pong-wasm.web.app/. You can open another tab if no one wants to play with you ;(

Getting started

• Compile the frontend code: make
• Start a fileserver to serve that code: cd fileserver && go run server.go
• Start the game server : cd server/cmd && go run main.go
• Connect to localhost:3000

Architecture

Client and server run the game engine, running at 128 ticks. Client sends its keyboard/touch input at a fixed frequency to the server, and both predict the next state of the game. When the client receives a server update, it reconciles both predictions by "replaying" the events that have happened since the last server packet was received.
