function - Meteor - Setting Session variables in Asynchronous Calls -

-

i have problem setting session variables inside of meteor.call function. appears meteor won't set session variables whatever ask outside of scope of function. 

meteor.startup(function () {   // code run on server @ startup   // prompt name    var playername = prompt("please enter name:", "");   meteor.call('createplayer', playername, function(error, result) {     console.log("player_id: " + result);     session.set("myplayerid", result);     console.log("session_player_id: " + session.get("myplayerid"));   });    console.log("session_player_id2: " + session.get("myplayerid"));   session.set("gamestate", show_lobby); });

the console prints out:

player_id: correct id

session_player_id: correct id

session_player_id2: undefined

as can see, session variable no longer correct outside of scope of function. suggestions?

the call createplayer asynchronous, order of execution be:

  1. prompt user
  2. start call createplayer
  3. log myplayerid session variable (session_player_id2)
  4. finsh call createplayer: set myplayerid session variable in callback

because (4) execute after (3), undefined when trying log "session_player_id2". if that's thing going on (i.e. there isn't bug somewhere else in code), should able following in browser console:

console.log(session.get('myplayerid'));

and, hopefully, correct result. answer original question: don't see wrong here - session variable still available outside of scope. appears misunderstanding of behavior of asynchronous functions.

i'm working in node js , i'm trying send array, clients, server every client normal emit, keeps giving me error: data = json.stringify(ev); typeerror: converting circular structure json shortly, do. var clients = new array(); io.sockets.on('connection', function(socket) { clients.push(socket); socket.on('loginuser', function(data){ io.sockets.emit("getusers", clients); }); i've seen couple of other people having problem, answers didn't work out me. looking @ bigger problem, can't send array of sockets client side. sockets objects make sense in current context/process. if want control sockets client side, instead add sort of rpc functionality.
