Hello everyone, I am wondering how do I run the node on the server side to be able to calculate the physics of various movements that I will make in the game menu, any recent tutorial? ---

All the physics (MatterJS and Arcade) is entirely calculated on a NodeJS server. The client only received the positions {x, y} and other necessary properties like rotation, animation and tint of each object. It uses a unmodified Phaser 3.16.2 version from npm. Example You can [play the example here](http://phaser3-multiplayer-example.herokuapp.com/). It runs on NodeJS on Heroku (Free Dyno in Europe) which causes the example sometimes to take about 1 minute… ---
