Hi! I was wondering, is it possible to reference a room from room ID, say send message to all clients in room?
I have different classes for state, entites, players etc which don't have reference to the parent room class and therefore can't use 'send' method within those classes.

Thanks!

Hi @veggis,

You may store the room reference on those specific entities by using @nosync.

Example:

import { Room, Client, nosync } from "colyseus";

export class Player {
  x: number;
  y: number;

  @nosync client: Client;
  @nosync room: Room;
  
  constructor (client: Client, room: Room) {
    this.client = client;
    this.room = room;
  }

  sendSomething (data: any) {
    this.room.send(this.client, data);
  }
}

This way, the client and room properties won't be synched to the client-side.

Hope this helps. Cheers!

@endel Sorry to bother you, but could you give an example with js?

I'm using babel to transcribe decorators, which is working but not for variables.

After some digging around in the docs I got it. Defining objects non-enumerable does the trick.

@veggis have you a sample in JS with non enumerable property?

@lezanardi

function setEnumerable(object) {
    let private = {};

    for (let key in object) {
        Object.defineProperty(private, key, {
            value: object[key],
            enumerable: false,
            writable: true
        });
    }

    return private;
}

Will return the passed object with all the items non-enumerable.
