2. 카메라 제어 입력 환경설정 | 언리얼 엔진 4.27 문서

카메라 제어로 무엇을 할 것인지 결정하고, 그에 맞게 입력을 구성해 줘야 합니다. 이 프로젝트에서는 마우스 오른쪽 버튼을 누르면 따라다니는 거리를 줄이고 시야를 확대하도록 하겠습니다. 마우스로 보는 각도를, WASD 키로 폰 의 이동을 제어하도록도 합시다. 그러기 위해, 언리얼 엔진 에디터의 편집 드롭다운 메뉴의 프로젝트 세팅 을 열겠습니다.

액션 매핑 하나와 축 매핑 넷을 다음과 같이 정의해 줘야 합니다:

액션 매핑
ZoomIn	오른쪽 마우스 버튼

축 매핑
MoveForward	W	1.0
	S	-1.0
MoveRight	A	-1.0
	D	1.0
CameraPitch	MouseY	1.0
CameraYaw	MouseX	1.0

입력 핑 작동방식에 대해 더욱 자세히 알고픈 경우, 플레이어 입력 및 폰 문서를 참고하시기 바랍니다.

입력을 정의했으니, 그에 반응하는 코드를 작성해 줘야 합니다. 다음 작업을 위해 Visual Studio 로 돌아가겠습니다.
