贪吃蛇代码(新手)

制作大体流程如下:

进场界面的绘制,使用定义的gotoxy函数控制光标位置,color函数改变颜色

游戏界面的绘制,使用循环分三次绘制边框和内部,注意横向间距为2,竖向为1

蛇身的绘制,采用链表逐个绘制蛇身部分

食物的产生,采用头文件,使用srand函数改变种子,注意每次产生食物遍历蛇身判断是否与蛇身重合,若重合再次产生食物

采用keyboardControl函数,与键盘交互,同时根据每次交互,判断是否吃到食物,吃到食物长度+1,否则正常移动

每次移动实时显示分数和速度,采用全局变量实现

ESC退出确认要求用户输入字符串,保证更安全地输入采用s_gets函数

游戏结束条件是撞到墙或者咬到自己或者自行退出,前两者用坐标实现

游戏结束后用frees函数释放内存

博主自己也是新手,如果有什么地方不对望指正,一起加油吧!
