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

Development Programming & Scripting AI

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.
