Error on re-joining a match with NetworkLobbyManager

Hi, I am using the standard NetworkLobbyManager, and I am getting this error:

ArgumentException: An element with the same key already exists in the dictionary. System.Collections.Generic.Dictionary`2[UnityEngine.Networking.Types.NetworkID,UnityEngine.Networking.Types.NetworkAccessToken].Add (NetworkID key, UnityEngine.Networking.Types.NetworkAccessToken value) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System.Collections.Generic/Dictionary.cs:404) UnityEngine.Networking.Utility.SetAccessTokenForNetwork (NetworkID netId, UnityEngine.Networking.Types.NetworkAccessToken accessToken) (at C:/buildslave/unity/build/Runtime/Networking/Managed/UNETTypes.cs:119) UnityEngine.Networking.NetworkManager.OnMatchJoined (UnityEngine.Networking.Match.JoinMatchResponse matchInfo) (at C:/buildslave/unity/build/Extensions/Networking/Runtime/NetworkManager.cs:1022) MenuWaitingForConnectingToMatch.OnMatchJoined (UnityEngine.Networking.Match.JoinMatchResponse response) (at Assets/scripts/menu/main menu/Network/MenuWaitingForConnectingToMatch.cs:58) UnityEngine.Networking.Match.NetworkMatch+<ProcessMatchResponse>c__Iterator0`1[UnityEngine.Networking.Match.JoinMatchResponse].MoveNext () (at C:/buildslave/unity/build/Runtime/Networking/Managed/MatchMakingClient.cs:302)

Seems to be a known bug, that is officially marked as "resolved" (see bugtracker issue 708502). Will this be fixed in a future release or is the bug back? Should I open a new bugtracker for this issue?

 

It's fixed in code not yet released.

 

Could you give me a rough estimate about when this will be released?

 

Days, weeks, months?

 

5.2.2 same error

 

anyone knows how to fix it?

 

Is this still not fixed in the newest 5.3 Unity build?

There is a workaround in the thread for the Issue Tracker for this bug: http://issuetracker.unity3d.com/issues/matchmaker-cant-re-join-a-match-after-leaving

You have to create a new class, that extends the NetworkLobbyManager class override its MatchJoined function:

http://issuetracker.unity3d.com/issues/matchmaker-cant-re-join-a-match-after-leaving

Code (CSharp):

1.  
2. public virtual void MatchJoined(JoinMatchResponse matchInfo)
3. {
4. if (LogFilter.logDebug)
5. {
6. Debug.Log("NetworkManager OnMatchJoined ");
7. }
8. if (matchInfo.success)
9. {
10. try
11. {
12. Utility.SetAccessTokenForNetwork(matchInfo.networkId, new NetworkAccessToken(matchInfo.accessTokenString));
13. }
14. catch(Exception ex)
15. {
16. if (LogFilter.logError)
17. {
18. Debug.LogError(ex);
19. }
20. }
21. this.StartClient(new MatchInfo(matchInfo));
22. }
23. else if (LogFilter.logError)
24. {
25. Debug.LogError(string.Concat("Join Failed:", matchInfo));
26. }
27. }
28.  

This removed the bug for me, although I don't like to use workarounds. Why is this still an issue in 5.3, although it's officially fixed??

 

host:
1. Enable Match Maker
2. Create Internet Match (default)
client:
1. Enable Match Maker
2. Find Internet Match
3. Join match default
4. Stop
5. Return to step 1-3.
6. BOOM! Error

The problem is repeated in NetworkLobbyManager & NetworkManager too

video here:

 

Does this happen with the workaround I proposed?

 

yes,I tried all options

 

but the problem is in re-joining client to the server, creating a new Internet match had improved earlier.

 

Then I will not be able to help you. Unity is up again for fixing this...

 

problem solved. very strange)) if no change in the code (standart OnMatchJoined callback) - occurs error. if I use the proposed option - occurs error
but if you comment out -
// Utility.SetAccessTokenForNetwork(matchInfo.networkId, new NetworkAccessToken(matchInfo.accessTokenString));
everything works well !

Code (CSharp):

1.     private void OnFindMatch(ListMatchResponse matchListResponse)
2.     {
3.         if (matchListResponse.success && matchListResponse.matches != null)
4.         {
5.             singleton.matchMaker.JoinMatch(matchListResponse.matches[0].networkId, "", OnMatchJoinedNew);
6.         }
7.     }
8.     public void OnMatchJoinedNew(JoinMatchResponse matchInfo)
9.     {
10.         Debug.Log("NetworkManager OnMatchJoined ");
11.         // Utility.SetAccessTokenForNetwork(matchInfo.networkId, new NetworkAccessToken(matchInfo.accessTokenString));
12.         StartClient(new MatchInfo(matchInfo));
13.     }
