Want a C++ example of calling "UGameplayStatics::GetAllActorsOfClassWithTag" using UE 4.27.1?

Development Programming & Scripting C++
#1
  • Created a new project by selecting the Third Person C++ template.
  • Duplicated the existing “ThirdPersonCharacter”.
  • Inserted Female into the Actor tags of “ThirdPersonCharacter2”.
  • Changed the skeletal mesh of ThirdPersonCharacter2 to “SK_Mannequin_Female”.
  • Inserted Male into the Actor tags of ThirdPersonCharacter.
  • The C++ classes of ThirdPersonCharacter and ThirdPersonCharacter2 as seen in the World Outliner are MyProjectCharacter.cpp and MyProjectCharacter.h as seen in the Solution Explorer in Microsoft Visual Studio Community 2019.
  • In MyProjectCharacter.cpp I wrote 2 headers under the existing headers:
#include "Kismet/GameplayStatics.h" // Print to the log at runtime.
#include "Templates/SubclassOf.h" //GetAllActorsOfClassWithTag?

void AMyProjectCharater::jump()
{
	Super::jump();// Extend existing character movement functionality?
	TArray<AActor*> outActors = TArray<AActor*>();// is empty.
	TSubclassOf<AMyProjectCharacter*> myActorClass = TSubclassOf<AMyProjectCharacter*>(this);// MyActorClass should be a subclass of or the same class as this class?
	UGameplayStatics::GetAllActorsOfClassWithTag
	(
		GetWorld(),
		myActorClass,//?
		FName("Female"),
		&outActors
	);
	if (outActors.Num() > 0)
	{
		UKismetSystemLibrary::PrintString
		(
			GetWorld(),
			outActors[0]->GetName(),
			true,
			true,
			FLinearColor(0.0, 0.66, 1.0),
			60.0f
		);
	}
}

Use AMyProjectCharater::StaticClass() or this->GetClass() as actor class.
this is not a class it’s an instance.
Constructing a TSubclassOf doesn’t make sense.

I fixed it, thank you.
