C语言实现俄罗斯方块课程设计

本文实例为大家分享了C语言实现俄罗斯方块的具体代码，供大家参考，具体内容如下

该课程设计用VC++6.0操作如下：

1、文件->新建->文件->左边选C/C++ Header File->右边文件名命名为“tetris.h”->路径假定为桌面文件夹：tetris->确定。然后将下面红色字体标记的“头文件”代码粘贴至其中，保存并退出（或者关闭工作空间）。

2、文件->新建->文件->左边选C/C++ Header File->右边文件名命名为“tetris.h”->路径假定为桌面文件夹：tetris->确定。新建“tetris.c”源文件，将下面“源代码”代码粘贴到其中，保存并退出（或者关闭工作空间）。

3、文件->新建->工程->左边选Win32 Application ->右边工程名称命名为：tetris->路径假定为桌面文件夹：tetris->确定->一个空工程->完成。接下来：工程->增加到工程->文件。这时候，将头文件和源代码添加进去，调试使用。

1.头文件

//1.自定义枚举类型，定义7种形态的游戏方块
typedef enum tetris_shape
{
 ZShape=0,
  SShape,
  LineShape,
  TShape,
  SquareShape,
  LShape,
  MirroredLShape
}shape;

//2.函数声明

//(1)操作方块函数
int maxX();//取得当前方块的最大x坐标
int minX();//取得当前方块的最小x坐标
void turn_left();//当前方块逆时针旋转90度
void turn_right();
int out_of_table();
void transform();
int leftable();
int rightable();
int downable();
void move_left();
void move_right();

//(2)操作游戏桌面的函数
int add_to_table();
void remove_full();

//(3)控制游戏函数
void new_game();
void run_game();
void next_shape();
int random(int seed);

//(4)绘图函数
void paint();
void draw_table();

//(5)其他功能函数
void key_down(WPARAM wParam);
void resize();
void initialize();
void finalize();

//(6)回调函数，用来处理Windows消息
LRESULT CALLBACK WndProc (HWND,UINT,WPARAM,LPARAM);

2.源代码

//1.文件包含
#include<windows.h>
#include<time.h>
#include<stdio.h>
#include"tetris.h"

//2.常量定义
#define APP_NAME "TETRIS"
#define APP_TITLE "Tetris Game"
#define GAMEOVER "GAME OVER"

#define SHAPE_COUNT 7
#define BLOCK_COUNT 4
#define MAX_SPEED 5

#define COLUMS 10
#define ROWS 20

#define RED RGB(255,0,0)
#define YELLOW RGB(255,255,0)
#define GRAY RGB(128,128,128)
#define BLACK RGB(0,0,0)
#define WHITE RGB(255,255,255)
#define STONE RGB(192,192,192)

#define CHARS_IN_LINE 14
#define SCORE "SCORE %4d"

3.全局变量定义

//(1)
char score_char[CHARS_IN_LINE]={0};

//(2)
char* press_enter="Press Enter key...";

//(3)帮助提示信息
char *help[]=
{
 "press space or up key to transform shape.",
  "Press left or right key to mover shape.",
  "Press down key to speed up.",
  "Press enter key to pause game.",
  "Enjoy it.:-)",
  0
};

//(4)枚举游戏的状态
enum game_state
{
 game_start,
  game_run,
  game_pause,
  game_over,
}state=game_start;

//(5)定义方块的颜色
COLORREF shape_color[]=
{
 RGB(255,0,0),
  RGB(0,255,0),
  RGB(0,0,255),
  RGB(255,255,0),
  RGB(0,255,255),
  RGB(255,0,255),
  RGB(255,255,255)
};

//(6)方块的7中类型
int shape_coordinate[SHAPE_COUNT][BLOCK_COUNT][2]=
{
 {{0,1},{0,0},{-1,0},{-1,1}},
 {{0,-1},{0,0},{1,0},{1,1}},
 {{0,-1},{0,0},{0,1},{0,2}},
 {{-1,0},{0,0},{1,0},{0,1}},
 {{0,0},{1,0},{0,1},{1,1}},
 {{-1,-1},{0,-1},{0,0},{0,1}},
 {{1,-1},{0,-1},{0,0},{0,1}}
};

//(7)得分
int score=0;

//(8)下一个方块
shape next=0;

//(9)当前方块
shape current=0;

//(10)当前方块的每一部分坐标
int current_coordinate[4][2]={0};

//(11)游戏桌面
int table[ROWS][COLUMS]={0};

//(12)当前方块的x坐标
int shapex=0;

//(13)当前方块的\y坐标
int shapey=0;

//(14)方块下移速度
int speed=0;

//(15)每一帧开始时间
clock_t start=0;

//(16)每一帧结束时间
