Hi @endel, thanks for your quick answer. I understand why I was struggling now !
With your fix, I still can't deliver my messages to all clients.
For now I did this on async for testing purposes, but it's really ugly and unreliable

if (this.hasReachedMaxClients()) { 
   setTimeout(async () => {
      for (let sessionId in this.clients) {
         this.send(this.clients[sessionId], { message: "Hello world!" });
      }
   }
},  1000);

If you have a better way, I'll take it !
Have a nice day !

Hi,
I'm trying to create a gameroom with a maxClients.(clients are deleted if the leave the room lobby). When it's reached, I want to lock the room and send each client their id in the game as player (that is their order in the Room.clients array).

The problem I face is the client is added to the array in a async task, so I can't immediately begin the task in the onJoin() method because the last client as not been added yet when onJoin() is called.

I can't seem to find a callback for the room when a client is effectively added to Room.clients, so I can send each client their player id (different from their client id and sessionId) in the game.

It's I think a basic question, but I can't figure it out. I'm new to multiplayer gameserver, so maybe I'm not thinking the right way.
Regards and thanks for any help.
