Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Can't find a created session

Hi, there: I'm practicing create/join/find sessions via C++ programming. Of course I reference the only example project ShooterGame a lot.

The server is dedicated.

Now I use the class OnlineSubsystemNull and can successfully create a session on a dedicated server, but can't find it on localhost. It says finding session is successful but the number of sessions equals 0. The attachment is my create/find code. Please have a peek.CreateSessionFindSessions Thanks.

I'm currently having the same problem, so I would like to bump this up. I'm not using C++, but I'm doing the same general thing with blueprints. Did you ever figure this out?

Still am and packaging a project isn't fixing it

just to point up some possible reasons.. or points to check out

Did you..

  1. add the onlinesubsystem to the defaultengine.ini

  2. add the project dependencies in the Project.Build.Cs

are you able to connect directly by ip / console commands?

  • open MapName?listen (for server)

  • open (for client)

I have nearly the same code and it didn't work for me either. When working within the editor I always find 0 sessions. But when I baked a development build it was suddenly finding the other sessions. Maybe there is a bug in the editor. Many networking related things work different in editor.

Hi, UE4 baut bei PIE (PlayInEditor) schon eine Session auf. aktuell 4.81 scheint da nen Bug im Editor zu sein, du kannst nur nen Server erstellen mit dem Server (das Editor Fenster bei 2 Fenstern).

UE4 opens a Session in PIE (PlayInEditor). Currently in 4.81 it seems theres a bug, when opening a server on the client (second window) you have to create a server on the server (session in editor window not the exta window) to make it work
