플레이어 캐릭터 생성

이제 맵을 돌아다닐 캐릭터를 생성하겠다. ACharacter를 상속받는 AStealthCharacter를 생성한다.
이는 맵을 돌아다닐 모든 캐릭터들의 베이스 클래스가 된다.

방금 만든 베이스 클래스를 확장해서 AHitman을 생성하고 Blueprint BP_Hitman을 생성한다.
BP_Hitman에서 메시를 설정해주고 위치를 조정한다. (여기서는 엔진에서 기본제공하는 메시를 사용함)

Level에 끌어다 놓으면 잘 나온다.

C++ 에서 캐릭터 스폰

플레이어가 BP_Hitman을 조작하도록 할 것이기 때문에 게임 시작 시 C++ 에서 액터를 스폰한다.

StealthPlayerController.h에 다음 코드를 추가한다.

class AHitman;

protected:
	virtual void BeginPlay() override;

private:
	UPROPERTY()
	UClass* HitmanBlueprint;

	UPROPERTY()
	AHitman* Hitman;

다음은 StealthPlayerController.cpp의 생성자에 다음 코드를 추가한다.

static ConstructorHelpers::FObjectFinder<UClass> HitmanObjectFinder(TEXT("Blueprint'/Game/Blueprint/Character/BP_Hitman.BP_Hitman_C'"));
check(HitmanObjectFinder.Succeeded());
HitmanBlueprint = HitmanObjectFinder.Object;

그리고 다음 코드를 추가한다.

#include "Character/Hitman.h"

void AStealthPlayerController::BeginPlay()
{
	Super::BeginPlay();

	check(HitmanBlueprint);

	FActorSpawnParameters Param;
	Param.Owner = this;
	Param.SpawnCollisionHandlingOverride = ESpawnActorCollisionHandlingMethod::AlwaysSpawn;

	Hitman = GetWorld()->SpawnActor<AHitman>(HitmanBlueprint, FVector(0.0f, 0.0f, 90.0f), FRotator::ZeroRotator, Param);
}

이제 실행하면 맵 중앙에 잘 생성된다.
