初试linux编译（ubuntu+vim）+玩转智能蛇

其他 2018-12-26 03:27:48 阅读次数: 0

一.初试linux编译（ubuntu+vim）

步骤：
①下载vmware15+ubuntu桌面版映像
②安装ubuntu
③下载vim+gcc
在ubuntu终端输入：

sudo apt-get install vim-gtk
sudo apt-get install gcc

④安装完毕后进行编译测试
1）新建helloworld.c

vim helloworld.c
在这里插入图片描述

2）进入界面按 i 即可输入代码
在这里插入图片描述

3）按ESC再按ZZ（大写）即可保存并退出

4）再在终端输入以下代码进行编译

gcc helloworld.c

5）输入以下代码运行

./a.out

二.运行sin-demo（一个好玩的正弦函数动态展示）

三.简单贪吃蛇(字符版)——不可使用getch（）和清屏等操作

①程序头部(生成初始地图 礼物 蛇)
程序实现思想已经在我的注释里面啦~~
我想大家应该能很快理解的

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define SNAKE_MAX_LENGTH 10
#define SNAKE_HEAD 'H'
#define SNAKE_BODY 'X'
#define BLANK_CELL ' '
#define SNAKE_FOOD '$'
#define WALL_CELL '*'

//output the initial map,food and snake.
void output();
void creatrandomfood();

//use 'w'(up),'s'(down),'a'(left),'d'(right) and 'Enter' to move.
void snakemove();

//When the snake hits itself or hits the wall,the game will be over.
int gameover();


//the begining

②让蛇动起来
先参考TA的伪代码如下

再简单地转成c语言（实际上磕磕绊绊弄了好久，哭了~~）

③简单的贪吃蛇的效果图（由于不能用getch（）函数，所以比较简陋= =）
在这里插入图片描述

④在ubuntu内运行效果图（感觉linux中运行得流畅很多啊！！！）
在这里插入图片描述

⑤用kbhit（）函数进一步完善（丑陋的）贪吃蛇——不需要自己按回车了！！

注：需要在linux运行才行

四.玩转智能蛇

①伪代码
在这里插入图片描述

②实现程序（这一步坑略多，以为可以直接在之前的贪吃蛇加一个函数，不过把自己搞崩了= =）
1）障碍效果
在这里插入图片描述

2）自动吃
在这里插入图片描述

3）思考：一个长度为5的障碍物能困死该自动跑的蛇吗？
答：我认为不会困死，设置了最大长度以及最优路线，应该不会困死的。

终于做完了贪吃蛇的学习总结！！！
前前后后踩了很多很多坑，但也学习到了很多东西，这种感觉很充实~~
虽然我的智能蛇还是很（zhizhang）= =
但是它还丑啊（逃）

本次博客到此结束，希望大家也能收获这份乐趣♂
