이 문제를 3 시간 동안 해결하려고 노력했지만 그럴 수 없습니다. 나는 C++를 배우려고 노력하고 있지만 여기에 붙어 있습니다. 나는 그 문제를 모른다. 내 총알 개체와 함께 사용할 개체 풀을 만들려고했기 때문에 메모리 누출없이 쉽게 생성 및 생성 할 수있었습니다. 다음과 같이 내 소스는 다음과 같습니다기본 정의가 잘못 작성되어 SFML C++ 공용 생성자가 암시 적으로 삭제되었습니다.

고마웠다 첫 번째 오류는 총알 클래스의 생성자와 BulletPool 클래스의 업데이트 방법입니다.

난 그냥 C++ 그렇게 어떤 도움이나 critism 감사합니다, 감사를 배우려고 노력하고 있어요!
편집 모든 도움에 대해 감사드립니다. 나는 모든 문제를 밖으로 생각했다. BulletPool :: update의 문제점은 renderwindow 객체가 참조없이 전달 되었기 때문에 함수가 창을 복사하여 렌더링하지 못하게했습니다.
이 오류 메시지가 말하는대로, 당신이union 회원을 가지고 있기 때문에 발생
'sf :: Vector2f'는 * pod *가 아니므로 'union'은 [Unrestricted_union] (https://en.wikipedia.org/wiki/C%2B%2B11#Unrestricted_unions)입니다. – Jarod42
