이 글은 주로 C# 스네이크 게임의 구현 코드를 분석합니다. 관심있는 친구들은 참고하시면 됩니다
오늘은 심심해서 뱀을 만들어보고 싶었는데 인터넷에 그런거 많지만 직접 써봐도 괜찮을 것 같아요
뱀 분석
게임 규칙:
1. 뱀의 초기 길이는 5이며, 먹을 때마다 1개씩 증가하며, 레벨을 통과하려면 최대 15개가 필요합니다.
2 뱀은 파란색으로 표시되고, 음식은 녹색, 장애물은 검은색으로 표시됩니다.
3. 뱀이 조우할 때 자신이나 벽, 장애물을 사용하면 게임이 실패합니다.
4. 방향키는 뱀의 이동 방향을 제어합니다. .위로 이동하는 경우 바로 내려갈 수는 없으며 왼쪽, 오른쪽, 위로만 이동할 수 있습니다.
5 레벨을 통과할 때마다 속도가 증가합니다.
일반 아이디어:
1.지도는 그리드 형태로 표현되며, 뱀은 사각형으로 구성되어 목록
2개와 1개의 언급된 사각형이 있으며, 사각형에 저장되는 내용은 색상, 좌표, 통과 가능 여부, 음식인지
3입니다. 한 번 앞으로 나아가면 앞에 있는 사각형을 뱀 목록에 추가하고 목록에서 마지막 사각형을 제거하세요. 앞에 있는 사각형이 음식인 경우 마지막 사각형을 제외하고는 이동하지 마세요.
4. "http://www.php.cn/wiki/121.html" target="_blank">그 동안 반복하여 전체 이동
5. 스페이스바는 while 루프가속을 달성하기 위한 절전 시간
3개의 클래스와 기본 양식, 즉 Node(그리드를 나타내는 데 사용됨), Map(지도를 나타내는 데 사용됨), Serpent(뱀을 나타내는 데 사용됨), 또 다른 주요 형태입니다. 아래 코드를 순서대로 붙여넣으세요. 기본적으로 모든 메소드에는 설명
이 있습니다.Code 1 :
