For our winterplenum at inovex, i created this small example for a dedicated Godot Multiplayer server in the browser with websockets.

There are 3 projects

• The main game at the root of this repository
• The realtime-server, a second Godot project for the dedicated websocket server
• The brickserver, written in go for a lightweight persistence and event storage

This go server uses a boltdb via bolthold - to persist the current world and additionally persists all events in a second db, so you can replay all the brick-events and watch some timelaps :)

Most of the network code are in the Connection files. The important part is, to set the websocket client and server as network_peer to get everything working with Godots high level multiplayer API

After learning in DinoPoker that a position sync on every frame is working and looks smooth (but kills a small server with a few players), i tested to interpolte the positions with a timer only 10 times per second. Perhaps this can be done a bit more clever?

WASD - movement
E - drop a brick
Q - toggle camera
SPACE - jump
Click - delete brick
Colorpicker... pick colors

With the on/off toggle on the bottom right corner, you can toggle a grid movement where you only move in half-brick steps, so you can better control the position and build acutally something that is more than a big colored pile ;)

to just test it, there is an offline, non-persistent version, starting when no servers are found to communicate with.

i put together a simple docker-compose file ( also found in https://github.com/cdreier/godot-bricks-mp/tree/master/docker )

just do a HTML5 export into the docker/export folder and run docker-compose up

after everything is up, you can test it at http://localhost:8000/?server=ws://localhost:8001
