안녕하세요 lwjgl을 사용하여 카메라 좌표를 추가하는 데 문제가 있습니다. 나는 gluPerspective와 관련 있다고 생각합니다. 코드를 게시 할 것이지만, 마우스 지시를 움직이는 방법을 알려줄 수도 있습니다. 그리고 Minecraft와 같이 화면 중앙에 십자형을 긋습니다. 내 메인 코드에 MouseUpdates 코드를 구현하는 방법을 알려주십시오.LWJGL x, y, z를 사용하여 이동하는 방법
여기 내 코드입니다 :

내가 마우스 업데이트 클래스를 만들었습니다. 블록 및 청크 클래스에 대해 걱정하지 마십시오. 그들은 나중에 사용하기위한 것이다. 마우스 클래스는 십자형 커서이며 W 키나 위쪽 화살표를 누를 때 십자형 방향으로 움직입니다.
