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"

AI Controller Possess method called when opening a character blueprint asset using that AI Controller with AutoPossesAI = Spawned

Steps to reproduce:

  • Create a C++ project

  • Add a new AI Controller class

  • Override Possess method

  • Do a check(false) inside Possess method

  • Compile

  • Create a character blueprint, set the new AI Controller as the AI Controller class

  • Set the auto possess ai to "Spawned"

  • Close the blueprint editor

  • Open the character blueprint again

Editor will crash because the Possess method is called when opening the blueprint asset and we put a check assertion in that method.

If you try you will see that PossessedBy method in character is also called.

I don't know if it's a bug or not but it's a very weird behavior.
