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"

Validation causes Crash

Working with pointers in Unreal, I quickly got into the habit of validating them before using them. In a project with lots of spawned and deleted Actors the validation itself crashes my game. How would I resolve this?

 TArray<AActor*> SpawnedActors = {...};
     
 for (size_t i = 0; i < SpawnedActors.Num(); i++)
 {
     //Valid?
     if (!SpawnedActors[i]) continue;
     if (!SpawnedActors[i]->IsValidLowLevel()) continue;
     if (!IsValid(SpawnedActors[i])) continue;        // <-- This sometimes causes a crash!
     if (SpawnedActors[i]->IsPendingKill()) continue;
     if (SpawnedActors[i]->IsActorBeingDestroyed()) continue;
 }

Thank you and best regards, Simon

I've added UPROPERTY() to the variable.I'll mark this as answered if further testing shows that the crash is gone.
