window下 纯c 实现 贪吃蛇 小游戏
游戏说明 按方向键上下左右(w a s d)，可以实现蛇移动方向的改变。 短时间长按方向键上下左右其中之一，可实现蛇向该方向的短时间加速移动。 按空格键可实现暂停，暂停后按任意键继续游戏。 拥有计分系统 游戏效果展示 实现每一块身体永远比前一位慢一拍 永远执行前一位身体的上一个动作 以此实现 蛇行走位 游戏代码 #include #include #include #include #define mapX 20 #define mapY 20 int map[mapY][mapX];

游戏实现核心思想 每一块身体都有 属于自己的行为队列 使用 队列数据结构实现 每一块新身体 都会copy 一份前一位身体 的行为队列 并在队列头添加 空行为【本文地址】
