Hello! I want log the struct array size.

TArray<FMyStruct> Arr{};

GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Orange, FString::Printf(TEXT("Struct Size: %s"), *UStruct::GetValueAsString(Arr)));

how to do it correctly?
Thank you :slight_smile:

int32 arrsize = sizeof(Arr);
GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Orange, FString::Printf(TEXT("Struct Size: %d"), arrsize));

hope it helps
cheers

TArray<FString> myarray;
GEngine->AddOnScreenDebugMessage(-1, 4.0f, FColor::White, FString::Printf(TEXT("Struct Size: %d"), myarray.Num()));

my array is struct type

yes it logs as int the size of my struct array but how to do it in string if it is possible?

I already showed the string in my code. And it does not matter, which contents the array has, I just used FString, could also be anything else)

So:

TArray<FMyStruct> myarray;
GEngine->AddOnScreenDebugMessage(-1, 4.0f, FColor::White, FString::Printf(TEXT("Struct Size: %d"), myarray.Num()));

And pure length number as string

GEngine->AddOnScreenDebugMessage(-1, 4.0f, FColor::White, FString::FromInt(myarray.Num()));

Added corrections, had just bad examples before…

this is size in strings and you already have the size in int32 to be logged in numbers

hope it helps
