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"

Host Session and Join Session Failing

Hi, I am trying to make my first multiplayer game. I have a feeling I am doing it wrong. I have it so when you press a button, it calls a function like host or join game. Whenever I press the button, it fails to function and shows the error message that I had implemented. How do I make these functions work as intended. I know the event is being called but just failing.Please help, Thanks! This is my blueprint:alt text
