C언어 게임 만들기(3일차)

3일차

오류 해결

 

• switch구문을 if문으로 수정
• 위에서 아래로 먹이를 먹을 때 방향 전환
• 약간의 버퍼와 완전히 먹지 않아도 먹이가 없어짐
• 이전 먹이와 근접한 거리의 먹이를 먹었을 경우 다른 먹이가 생성되지 않음

수정된 부분

• 벽에 닿으면 죽음
• 커서 제거
• 먹이와 뱀의 색깔 구분

 

새로운 오류 발견

• 게임 진행 중 먹이가 갑자기 한 개 더 생기는 오류(원인 불명)

다음 목표

• 뱀의 길이 증가
•  ending 화면 생성
• 뱀 한 마리 더 추가
• 먹이 생성 범위 증가
