C语言之飞机大战游戏

本文实例为大家分享了C语言之飞机大战游戏的具体代码，供大家参考，具体内容如下

技术原型

1、void gotoxy(int x, int y) 函数，该函数可以使光标去到（x,y）的位置进行打印；
2、链表，用于存储状态；
3、windows.h中有非阻塞输入，_kbhit()；
4、随机生成数；
5、视觉暂留；
6、碰撞检测；
7、清屏函数；
8、设置边界；

技术路线

1、设置一个边界；
2、维护一个子弹的列表；
3、维护一个敌机的列表；
4、初始化飞机的位置；
5、每隔一秒钟生成一架敌机，生成位置x坐标随机，坐标为0；
6、设置点击空格生成子弹；
7、设置while(1)循环，在其中每次进行清屏和更新；
8、每次更新遍历子弹链表，使所有子弹的位置向上移动1；
9、每次更新遍历敌机链表，使所有敌机的位置向下移动1；
10、碰撞检测，遍历子弹和敌机列表，发现碰撞则从各自的链表中移除碰撞的节点；
11、当有敌机碰撞到本机游戏结束；
12、当子弹或者敌机碰撞到边界，则从链表中移除；
13、每次检测到碰撞加一分。
