나는이 그림을 그리기 위해 머리카락을 꺼냈다. 간단한 버튼이있어서 마우스가 끝났는지 확인한 다음 텍스처가 바뀌면 텍스처를 변경합니다. 그것은 잘 작동합니다. 그러나 믹스에 카메라를 추가하면 모든 것이 손상됩니다. 경계 상자 충돌에 사용하는 마우스와 사각형을 변형하려고 시도했지만 작동하지 않습니다.2D 카메라 XNA와 경계 상자 충돌

내가 무엇이 잘못 100 % 확신하지만이 버튼을 누를 때 마우스의 위치는 변경 여기에 버튼 내 코드입니다. 나는 정말로 혼란 스럽다, 나는 전에 카메라로 일한 적이 없다. 어떤 도움이라도 대단히 감사 할 것입니다. 감사!
업데이트 : 카메라를 이동하고 시도하기 전에 마우스가 버튼 위에 있음을 감지합니다. 그 후 직사각형의 좌표가 계속해서 증가합니다.
