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"

There is my blueprint script, called from the BeginPlay of my Level Blueprint. It is located on the Game Instance Class of my project.

Thank you

Looks like you aren't using the correct player controller. This is probably an issue with the world settings for the level. And due to the incorrect controller you aren't creating the widget properly so the variable is not valid when you try and add the menu widget to the viewport. Fix the controller issue and the other one will likely resolve.

Thanks for your reply. The issue seems to be this one. It works if I uncheck the "Run dedicated server" but with this option I'm getting the error. How can I fix this or know the index of the current player to select?

Dedicated servers are "headless" meaning that they have nothing to render to. Do a check if Dedicated or not, and only call this code if NOT a Dedicated server.
