저는 게임을 만들고 작은 800x500 창, 최대화 된 창 및 전체 화면의 3 가지 모드를 갖기를 원합니다. 활성 렌더링을 사용하여 그래픽을 jframe 및 paint으로 components을 layeredpane에 그릴 계획입니다. 나는 2 개의 버퍼와 함께 bufferstrategy을 사용하고 있습니다. 이미 보이는 화면을 전체 화면으로 설정하는 문제를 해결하기 위해 창의 크기가 변경 될 때마다 (프로그램 내 버튼으로 창 자체로 크기 조정할 수 없음) 적절한 크기가 주어지면 새 jframe이 생성됩니다 성분을 paint으로 함유하는 jpanel을 frame에 첨가한다. 웬일인지, bufferstrategy의 그래픽으로 칠할 때마다 오프셋이 있습니다 (0,0에 그림이 그려지면 -3, -20 주위에 나타납니다. 왜 그런지 모르겠습니다.) 중 당신이 줄 수있는 모든 도움을 주시면 감사하겠습니다. 그래픽으로 그리거나 (현재 JFrame의의 레이어 패널에) 그래픽 페인트 구성 요소를 호출합니다. enter code here활성 렌더링을 사용하는 스크린 관리자 클래스 만들기
