Little guide on how to use UE4's UKismetSystemLibrary::SphereOverlapActors

UE4_SphereOverlapActors_Example

#include "Kismet\KismetSystemLibrary.h"

// Set what actors to seek out from it's collision channel
TArray<TEnumAsByte<EObjectTypeQuery>> traceObjectTypes;
traceObjectTypes.Add(UEngineTypes::ConvertToObjectType(ECollisionChannel::ECC_Pawn));

// Ignore any specific actors
TArray<AActor*> ignoreActors;
// Ignore self or remove this line to not ignore any
ignoreActors.Init(this, 1);

// Array of actors that are inside the radius of the sphere
TArray<AActor*> outActors;
	
// Total radius of the sphere
float radius = 750.0f;
// Sphere's spawn loccation within the world
FVector sphereSpawnLocation = GetActorLocation();
// Class that the sphere should hit against and include in the outActors array (Can be null)
UClass* seekClass = AEnemyBase::StaticClass(); // NULL;
UKismetSystemLibrary::SphereOverlapActors(GetWorld(), sphereSpawnLocation, radius, traceObjectTypes, seekClass, ignoreActors, outActors);

// Optional: Use to have a visual representation of the SphereOverlapActors
// DrawDebugSphere(GetWorld(), GetActorLocation(), radius, 12, FColor::Red, true, 10.0f);

// Finally iterate over the outActor array
for (AActor* overlappedActor : outActors) {
	UE_LOG(LogTemp, Log, TEXT("OverlappedActor: %s"), *overlappedActor->GetName());
}

Thank you!
