Colyseus.js : client.onClose , client.onError not found.

[shashank]

On migrating to Colyseus.js 0.11.x , I could not find the onClose and onError callbacks in Colyseus client. Are they deprecated ?

hi @shashank , yes, those doesn't exist anymore in 0.11.

@dpastorini : Is there any way to detect connection lost from client-side ?Currently I am not getting any error or call back , when the connection is lost or the server goes down.

I was asking the same :P
@endel any ideas how we could detect on the client if the server is down?
We could check if the client left the room, but that's different from a connection error, we could make an user leave the room on purpose.
Maybe we will have to look for a work around and do some checks onLeave(), like set a property in the room before leave it, and then check for that property to see if we leave it on purpose or if the server just kicked the player.

room.onLeave((code) => {
  if(room.leaving === true) {
       // all good, do nothing
   } else {
      alert('connection lost'); window.location.reload();
   }
});

Hi @dpastorini @shashank,

During onLeave in the client-side you can check for the code being anything else than 1000 to detect an abnormal disconnection:

room.onLeave(code => {
  if (code > 1000) {
    // abnormal disconnection!
  } else {
    // the client has initiated the disconnection
  }
});

I've just fixed the closing codes on version colyseus@0.11.7, so please upgrade. I apologize for the inconvenience! 🙈

Hi @endel : Thanks for the update. Is there any way to detect disconnection when the player has not joined a room yet?
