문제가 실제로 내 프레임 버퍼 등의 방법도 batch.begin에 전화를했다 (prepareLightFrameBuffer)()와 함께했다 좋아; 및 batch.end(). 보기가 엉망이 된 것처럼 보일 수도 있습니다. 이 문제를 해결하기 위해 뷰포트를 다시 적용하고 렌더 메서드에서 뷰를 다시 설정합니다 (참고 : 스테이지가있어서 viewport.apply()도 여기에 호출해야하며 stage.render() 메소드).
여기에 관심이있는 경우 GameRenderer의 전체 코드가 나와 있습니다. 내가 왜 calculateScissors은`batch.getTransformMatrix`에서 물어보고 싶은, 어떻게 든 그것을 간단하게 할 수있다 생각하지만 난 아무 생각이 어떻게 할 것이 없습니다 그래서 :)

실례 나는 더는 OpenGL/매트릭스 전문가를 생각하지? 카메라에서 현재 매트릭스를 얻어야한다고 생각합니다. 그리고 당신의'batch.setProjectionMatrix (camera(). combine);'가 올바르게 설정되었다고 가정하면 renderize에서 카메라를 직접 업데이트하고 렌더링에 적용하여 작동하는지 확인할 수 있습니다. 가장 좋은 디버깅 방법은 크기 변경 전후의 Camera/Viewport 값을 기록하고 어디가 잘못되었는지 확인하는 것입니다. – Tokenyet
해답을 제공해 주셔서 감사합니다. 가위는 공식 문서 (https://github.com/libgdx/libgdx/wiki/Clipping,with-the-use-of-scissorstack)에서 가져옵니다. 그래서 변환 행렬을 사용했습니다. 내일 디버깅을 좀 더 시도 하겠지만 분명한 실수를 보시겠습니까? 카메라를 수동으로 설정하면 먼저 뷰포트가 필요한 이유는 무엇입니까? – Simon
죄송합니다. ** 시도해 보았습니다 ** 문제를 발견 할 수있는 방법 일 수 있습니다. 어쩌면 더 적게 이야기해야 할 수도 있습니다. – Tokenyet
