@endel Thank you for your reply.But this method is called to return an object. How can I put the object into the database?use JSON.stringify?

//serverSide
onCreate(options) {
    //check if need restore
    if(true){
     let roomstate=getRoomStateFromDB();
     this.state=JSON.Parse(roomstate);// Is it used like this?
    }

}

async onDispose() {
    let roomtState=JSON.stringify(this.state.toJSON());
    storeDataBase(roomtState);// Is it used like this?
}

There are many nested data in this root-state. It will be very cumbersome to assemble them when they are stored and used separately. Is there any way to save only root-state?

@endel Can you give me some advice？thank you.

Hi all,
In some cases, the room needs to be destroyed but the state information of the room needs to be recorded in the database so that the state can be restored next time.What do I need to do to implement this requirement? Do I serialize and deserialize directly?

...
let playerList=new Map();//store player client info
async onAuth(Client client,options){
   
    if(validate(options.token){
    //if already joined
    if(playerList.get(options.token)){
          //disconnect old clients
          this.clients.foreach(oldClient){
            if(client.id==playerList.get(options.token)) oldClient.discontent();
         }
    }
        playerList.set(options.token,client.id,)
    }

}

hi,you should use matchMaker.defineRoomType to defind this room.

Hi all,
When I connect to the server and close WiFi, the server can receive the message quickly, but the client needs to wait about 50 seconds to receive the notice ofonLeave. This problem is the configuration problem or the lack of heartbeat detection? How can I fix it?
The client is JS version.

Thanks!

@endel Yes, it is. Haha, Cheers!

Hi all,
In the document, only remove all listeners method.

Hi all,
I am using typescript to debug the project in VS Code. My project has ts-nodeand source-map-support packages installed. But still can't display the correct number of error stack rows. Is my operation wrong or need other settings?
thanks!

e.g.

@endel yeah,Because it is still necessary to distinguish between system exceptions and business exceptions. My current solution is to add a formarter in the client-side.tanks for reply.😁
