1.ncurse库 使用ncurse是因为案件响应灵敏不用回车头文件#includecurses.h 创建.c文件同时gcc编译也需要添加 -lcurses 主函数中 initscr();//ncurse界面初始化函数 printw();//ncurse模式下的print getch();//等待用户输入如果没这句话程序就退出了看不到运行结果 endwin();//程序退出调用改函数来恢复shell终端显示如果没这句话shell终端字乱码坏掉
2.Linux线程 程序都是从上到下运行要想2个同时运行需要线程一个程序有多个线程互不影响 线程头文件#includepthread.hgcc编译的时候需要添加-lpthread 运用 pthread_t th1; pthread_create(th1,NULL,func1,null);//func1为创建的函数null为函数中的参数 //void *func1定义的该函数返回值是void*型
3.食物随机不出边界
rand函数随机数
不出边界20x20rand%20对随机数取余数
4.制作贪吃蛇方向按键 vi /usr/include/curses.h 查看相应按键编码 方向头文件includecurses.h KEY_DOWN 0402; KEY_UP 0403; KEY_LEFT 0404; KEY_RIGHT0405; :cq退出
