俄罗斯方块demo

这是我的第一篇随笔，当然是发我写的第一个游戏啦！

大一（本人现在大二）寒假过完年，在家待着想起放假前计划写一个游戏的，因为本人立志走游戏开发这条路，加上大一上册学了C语言，就想写个游戏练练手。想了很久，最后决定写一个俄罗斯方块。

万事开头难，一开始真的不知道从何下手，所以百度查了一些资料（程序猿必须要学会百度），看了一下其他大牛写的，理了理思路，开干！

直接上代码！

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

#define SPACE 32 //空格键 旋转 
#define LEFT  75 //左方向键 向左移动 
#define RIGHT 77 //右方向键 向右移动
#define DOWN 80 //下方向键 加速向下移动 
#define ESC 27 //Esc键 退出 
#define Wall 2 //围墙 
#define Box 1 //方块 
#define Kong 0 
#define FACE_X 30 //方块长度 
#define FACE_Y 20 //方块高度 

void start_game(); //游戏循环 
void gotoxy(int x, int y); //设置光标位置 
void hidden_cursor(); //隐藏光标 
int color(int c); //设置颜色 
void init_face(); //初始化界面 
void init_dia(); //初始化方块形状 
void draw_dia(int base, int space_t, int x, int y); //画方块 
void draw_space(int base, int space_t, int x, int y); //画空格 
int border(int n, int space_t, int x, int y); //边界检测 
int del(); //删除增加分数 
void read_file(); //读入最高纪录 
void write_file(); //写入最高纪录 

struct Face
{
    int data[FACE_X][FACE_Y + 10]; //为1是方块,为0是空格
    int color[FACE_X][FACE_Y + 10];
}face;
typedef struct Diamonds

由于是大一写的，所以没有什么注释，我补了一些，如果有感兴趣的朋友直接私聊我（1527985747@qq.com），我们可以一起讨论，一起进步！！！
