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"

How to delete elements (from heap) from TArray with TFixedAllocator


Do I need manually delete components and if so then how.

Mean, I have UCLASS that inherits from AActor.
In this class is member without UPROPERTY.
It is without UPROPERTY because TArray with TFixedAllocator can't have it.
How I shoud delete elements from TArray and where - BeginDestroy, EndPlay, FinishDestroy, Destructor?

 class .... : public AActor
     TArray<UAudioComponent*, TFixedAllocator<2>> AudoComponents;
Product Version: UE 4.14

I found tutorial https://wiki.unrealengine.com/Garbage_Collection_%26_Dynamic_Memory_Allocation

And in it is section:

 if(!MyObject) return;
 if(!MyObject->IsValidLowLevel()) return;
 MyObject->ConditionalBeginDestroy(); //instantly clears UObject out of memory
 MyObject = nullptr;

Someone have idea this is good solution?
