기존 ThirpersonTemplete에 LineTrace추가하기

	FCollisionQueryParams _TraceParams;
	GetWorld()->LineTraceSingleByChannel(_HitOut, _Start, _End, ECC_Visibility, _TraceParams);
	DrawDebugLine(GetWorld(), _Start, _End, FColor::Magenta, false, 3.f);
}

 

맵변경

AnitiAliasing을 끄거나  Unlit를 끄면 성능이 가벼워진다.

 

 

 

 

TriggerBox delegation작성

UFUNCTION()
void OnComponentBeginOverlapTB(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor,
    UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult);

 

ANPC::ANPC()

 	// Set this character to call Tick() every frame.  You can turn this off to improve performance if you don't need it.

}

 

게임모드에서 디폴트맵으로 가든을 설정하고 BP_NPC를 디폴트폰으로 설정한다.

프리뷰카메라가 이정도 나오게 완성한다.

카메라를 배치한다.

void ANPC::OnComponentBeginOverlapTB(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)
{
	GEngine->AddOnScreenDebugMessage(-1, 5.0f, FColor::Yellow, TEXT("debug"));
	APlayerController* MyPlayerController = UGameplayStatics::GetPlayerController(this, 0);
	MyPlayerController->SetViewTarget(this);
	MyPlayerController->SetInputMode(FInputModeUIOnly()); // UI만 인풋된다.
	MyPlayerController->SetShowMouseCursor(true);
}

 

NPC.cpp

NPC.h

 

NPC에서 WBP_ITEM을 연결해준다.

이제 Exit에 기능을 연결한다. isVariable을 체크한다.

위젯을 지워주고 마우스를 없애주고 ViewPort로 부터 디태치해준다.

실행해보니가 Exit를 눌러도 Widget이 지워지지 않아 따로 TestPlayer를 만들어 실험해 보니 Wdiget은 문제 없다.
