贪吃蛇大作战下载，实战C/C++贪吃蛇大作战

这是一个贪吃蛇大作战类游戏，修改特性为 AI 不互杀；

该程序有四个类：蛇基类 SnakeBase，玩家类 Player，AI 类，Game 类；SnakeBase 和 AI 均继承自 SnakeBase，SnakeBase 提供基础接口；

Game 提供数据初始化以及游戏主循环。

程序设计之初，采用“实运行”方式，即所有动画均在地图 imgMap 上真实绘制，这样却有一些严重的问题，需要不断地记录节点背景以恢复节点经过的地方等。

后修改为“虚运行”方式，判断位置是否可视后直接绘至窗口内，这样大大降低时间开销，同时不会因为蛇靠近而产生不可擦除的颜色。

至于蛇运行，采用位置继承，即节点下一个位置为上一个节点的位置，但是会发现跨度太大，解决办法是在这个跨度中插入适当帧数。

执行效果如下：

完整的游戏源代码如下：
