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"

Android to Android multiplayer can't join session

I've been working on trying to connect my android device to another android device that is hosting my game. I'm able to do so if I run the "open" command with the IP address, but when I try to use the "Join Session" node, it just hangs indefinitely. I've set the online subsystem to null and have it configured to be LAN only. Any help would be most welcome! Here are the BP functions that I have for hosting/joining: alt text

are both devices connected to wi-fi on the same network?

They are, it seems strange that join session fails but they can still connect by just using their IP addresses with the console command

Hello hesto2, Did you find solution for your issue?

Hey anton, it appeared that this ended up being a bug in version 4.20/4.21 of the engine. It worked previously in 4.19 and I'm pretty sure has been fixed in 4.22
