This is where we can share progress

Massive WIP; check out https://eds-game-for-ftp-game-jam-2022.initialed85.cc/

Arrows to fly around, left alt to fire, anyone else at the above URL at the same time will be in the same multiplayer game.

The code is at https://github.com/initialed85/eds-game-for-ftp-game-jam-2022

• Rust w/ Bevy for game framework
• Network multiplayer via WebSocket
• Native server
• WASM client
• Shipped on my home Kube cluster

Noteworthy items:

• Client's send key input events as they happen
• Server applies inputs and executes physics
• Server sends updates at 15 Hz
• Clients execute physics at 60 fps in between updates from server to keep things feeling smooth
• Clients use exponential smoothed moving average to keep things further feeling smooth (handling the error between the Client-executed physics and the next update of truth from the Server)

Remaining stuff

• Fix the server side timestep
  • The feel of the game varies pending how much grunt the server has
• Somehow establish time sync between Server and Client and use that to more accurately apply input events and update events (vs right now it just happens on receipt)
  • The feel is further impacted by latency / jitter from Client to Server
• Implement lives and damage for the players or something like that
• Have some UI stuff
  • Maybe implement a status / remote control API out of the Client and do it all in React on the browser side?

Realistically

• Probably leave it as it is because I'm bored with it and it's as complete as any of my other personal projects (i.e. not)
