Wrong Matchmaking and leaderboard behavior

Game Design
1

Hello !
I’ve almost finished the game i’m working on but I have a few issues i’m encountering with nakama using godot :

  • I want to retrieve a single user leaderboard record but the API returns a bunch of them even thought I provided a single user_id :
    var result : NakamaAPI.ApiLeaderboardRecordList = yield(client.list_leaderboard_records_async(session, leaderboard, [user_id]), "completed")
      if result.is_exception():
          print("An error occured: %s" % result)
          return
      print(result.records)

Returns:

I checked to see if wanted user were in the records but it isn’t even in their. But i’m sure it is in the leaderboard since it appears when I retrieve records around user like I describe later

  • When I want to retrieve leaderboard records around user, it returns correctly a bunch of records but if they have the same score, the ranking is all messed up and it even ommit some of them :

  • When I want to use matchmaking with a query, it doesn’t find any match no matter how much users are in queue and matching the requirements :

var query = "properties.league:bronze"
  var min_count = 2
  var max_count = 2
  var string_properties = {
      "league": "bronze"
  }
  var numeric_properties = {}
  var matchmaker_ticket : NakamaRTAPI.MatchmakerTicket = yield(
      socket.add_matchmaker_async(query, min_count, max_count, string_properties, numeric_properties),
      "completed"
  )
  if matchmaker_ticket.is_exception():
      print("An error occured: %s" % matchmaker_ticket)
      return
  print("Got ticket: %s" % [matchmaker_ticket])

It succesfully returns a ticket but “received_matchmaker_matched” callback is never trigerred. It works well with “*” query though. Anyone would see the problem ?

Thanks in advance for your help!

Ok i just tryed getting record by user_id directly from an http get request on the browser and it’s working fine. Must be a problem with Godot Nakama API then. Still have issues for around user records and matchmaking though

Edit: Just found out there is a separate object called “owner_records” in the response. One probleme fixed 2 more to go !
For the record around owner i’ll do a manual sort for now.
Is there a way to track current users in matchmaking pool ?

Hi, I’m facing this problem and when I use query “*” I get a matched result where all the players rave string_properties={} and numeric_properties={}, so the real issues seems to be the values of those 2 dictionaries are not really sent to server.

in NakamaSocket.gd the method _send_async starts with
logger.debug(“Sending async request: %s” % p_message)

and in this call the message still contains the dictionaries, but I don’t know why the are lost in the way

how did you solve it?
