[UE] 워프 Top View 만들기

지난 시간에 구현한 워프는 워프 시 일반적인 플레이어의 뷰에서 커서가 가르키는 방향으로 이동하였다. 플레이어의 시점에서 워프를 실행하기 때문에 뒤로 이동하려면 뒤를 돌아야 한다. 이동 가능한 범위가 한 눈에 들어오도록 Top View를 제공해 워프 이동이 좀 더 다양하도록 선택권을 넓혀줄것이다. 마우스 우클릭으로 Top View가 나오도록 SubAction_Warp를 만들것이다.

카메라 이론 설명

 

W: 직육면체

VP: Frustum

 

Vp: 직육면체

 

종횡비율 Aspect Raio

 

 

OrthoWidth만 정하고 OrthoHeight는 정하지 않는 이유는?

Width를 가진 상태로 종횡비로 Height를 정하기 때문이다.

CMovementComponent  -  Top View 시에 Player를 절대방향으로 움직이도록 수정

 

평상 시에는 Actor(=플레이어)의 전방 방향을 기준으로 플레이어가 움직인다. 하지만 Warp를 위한 우클릭 시 플레이어가 이동할 때는 Orthographic Top View이기 때문에 플레이어를 절대방향으로 움직일 수 있도록 수정해준다.

Top View로 사용할 변수 추가

•  class ACameraActor* CameraActor;

 

FORCEINLINE 함수 추가

• FORCEINLINE void EnableTopViewCamera() { bTopViewCamera = true; }
• FORCEINLINE void DisableTopViewCamera() { bTopViewCamera = false; }

}
 
void UCMovementComponent::OnVerticalLook(float InAxis)

	OwnerCharacter->AddControllerPitchInput(InAxis * VerticalLook * GetWorld()->GetDeltaSeconds());
}

Top View 시 플레이어의 방향을 플레이어 기준이 아니라 XAxisVector, YAxisVector로 변경시켜 준다.

• void UCMovementComponent::OnMoveForward(float InAxis)
  • if (bTopViewCamera)
        direction = FVector::XAxisVector;
• void UCMovementComponent::OnMoveRight(float InAxis)
  • if (bTopViewCamera)
        direction = FVector::YAxisVector;
