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"

Why do i get errors for my turret rotation blueprints?

Hi, can someone please explain to me why i get these errors. When i click on play it works properly, the turrets are following the player and spawning projectiles. But after the session ends it gives a ton of errors. Thank you. :)

Your function "updaterotation" is calling GetPlayerPawn which, when the game is shutting down, returns invalid because the player pawn is destroyed/being destroyed.

When you call GetPlayerPawn, you should call IsValid before you actually reference it in SetWorldRotation.

Works perfect now :) I was thinking it might have been something like that, but was not sure how to check if player is still alive. IsValid + Branch works fine. Thank you very much :D
