프로그램이 정지되고 해결책을 찾을 수 없습니다. SDL 및 C++

Question

코드에서 어디에서나 확인한 결과 프로그램을로드 할 때마다 프로그램이 정지되는 이유를 찾을 수 없었습니다. 문제는 새로운 AI 헤더 인 "schoolboy.h"가 포함 된 후에 발생했습니다. 나는 이미지를 blit하려고 시도하는 것이 문제가 아니 었는지 확인했다. 그래서, 약간의 테스트 후에, 나는 "schoolboy.h"내의 "void schoolboy_action()"에 문제가 있다고 생각했습니다. 다음은 전체 프로젝트 코드입니다. 나는 한 시간 동안 그 부분을 보았고 해결책을 찾지 못했습니다. 나는 그것이 정말로 길다는 것을 알고있다, 그리고 내가 구멍을 채울 것을 계획하는 그것에 약간의 구멍이있다. 그러나 나와 나와 견뎌 라.

모든 파일이 서로 관련되어 있습니다. 특히 schoolboy.h가 그 이유입니다. 대답을 찾으면 그 이유를 설명 할 수 있습니까? 어떤 도움을 주셔서 감사합니다!

Answer 1

schoolboy.h 끝에있는 instance = instance + 1 행은 while 루프 외부에있는 것처럼 보입니다. 결국 while 루프가 끝나기 위해 증가합니다.
