easyx高仿贪吃蛇

已经一周没有发新文章啦，看着这点击量掉的不是一般的快啊！这样可不行，所以，今天我就发一篇来啦！

游戏介绍

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；

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，

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，

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，

功能实现

• 支持16个方向的移动
• 自动彩豆生成
• 碰撞检测
• 全自动电脑AI移动、攻击、拾取食物
• 地图边界
• 地图网格
• 长度、击杀显示
• 鼠标控制
• 高仿原版贪吃蛇界面
