c语言设计俄罗斯方块

以下是一个简单的C语言俄罗斯方块的设计示例，包括视图和模型的实现：

1. 视图部分（view.h和view.cpp）：

view.h：

#ifndef VIEW_H
#define VIEW_H

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

#define WIDTH 10
#define HEIGHT 20

void gotoxy(int x, int y);
void draw_block(int x, int y, int color);
void draw_board();
void draw_shape(int x, int y, int shape, int direction, int color);
void clear_shape(int x, int y, int shape, int direction);

#endif

view.cpp：

#include "view.h"

void gotoxy(int x, int y) {
    COORD pos = { x, y };
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), pos);
}

void draw_block(int x, int y, int color) {
    gotoxy(x * 2, y);
    printf("[]", color);
}

void draw_board() {
    int i, j;
    for (i = 0; i < HEIGHT; i++) {
        for (j = 0; j < WIDTH; j++) {
            if (i == 0 || i == HEIGHT - 1 || j == 0 || j == WIDTH - 1) {
                draw_block(j, i, 15);
            }
            else {
                draw_block(j, i, 0);
            }
        }
    }
}

void draw_shape(int x, int y, int shape, int direction, int color) {
    int i, j;
    for (i = 0; i < 4; i++) {
        for (j = 0; j < 4; j++) {
            if ((shape >> (i * 4 + j)) & 0x0001) {
                draw_block(x + j + 1, y + i + 1, color);
            }
        }
    }
}

void clear_shape(int x, int y, int shape, int direction) {
    int i, j;
    for (i = 0; i < 4; i++) {
        for (j = 0; j < 4; j++) {
            if ((shape >> (i * 4 + j)) & 0x0001) {
                draw_block(x + j + 1, y + i + 1, 0);
            }
        }
    }
}

2. 模型部分（model.h和model.cpp）：

model.h：

#ifndef MODEL_H
#define MODEL_H

#include <time.h>

#define SHAPE_COUNT 7

enum {
    SHAPE_I,
    SHAPE_J,
    SHAPE_L,
    SHAPE_O,
    SHAPE_S,
    SHAPE_T,
    SHAPE_Z
};

enum {
    DIR_UP,
    DIR_RIGHT,
    DIR_DOWN,
    DIR_LEFT
};

typedef struct {
    int x;
    int y;
    int shape;
    int direction;
    int color;
} Block;

void init_model();
void new_block();
int move_block(int dx, int dy, int dshape);
int drop_block();
int rotate_block();
int is_gameover();

#endif

model.cpp：

#include "model.h"

int shapes[SHAPE_COUNT][4][4] = {
    {
        { 0, 0, 0, 0 },
        { 0, 0, 0, 0 },
        { 1, 1, 1, 1 },
        { 0, 0, 0, 0 }
    },
    {
        { 0, 0, 0, 0 },
        { 0, 1, 0, 0 },
        { 0, 1, 1, 1 },
        { 0, 0, 0, 0 }
    },
    {
        { 0, 0, 0, 0 },
        { 0, 0, 1, 0 },
        { 0, 0, 1, 1 },
        { 0, 0, 1, 0 }
    },
    {
        { 0, 0, 0, 0 },
        { 0, 1, 1, 0 },
        { 0, 1, 1, 0 },
        { 0, 0, 0, 0 }
    },
    {
        { 0, 0, 0, 0 },
        { 0, 0, 1, 1 },
        { 0, 1, 1, 0 },
        { 0, 0, 0, 0 }
    },
    {
        { 0, 0, 0, 0 },
        { 0, 1, 1, 1 },
        { 0, 0, 1, 0 },
        { 0, 0, 0, 0 }
    },
    {
        { 0, 0, 0, 0 },
        { 0, 1, 1, 0 },
        { 0, 0, 1, 1 },
        { 0, 0, 0, 0 }
    }
};

Block current_block;
int board[HEIGHT][WIDTH];

void init_model() {
    int i, j;
    for (i = 0; i < HEIGHT; i++) {
        for (j = 0; j < WIDTH; j++) {
            board[i][j] = 0;
        }
    }
    srand((unsigned int)time(NULL));
    new_block();
}

void new_block() {
    current_block.x = WIDTH / 2 - 2;
    current_block.y = 0;
    current_block.shape = rand() % SHAPE_COUNT;
    current_block.direction = DIR_UP;
    current_block.color = rand() % 7 + 9;
    if (move_block(0, 0, 0)) {
        exit(0);
    }
}

int move_block(int dx, int dy, int dshape) {
    int x = current_block.x + dx;
    int y = current_block.y + dy;
    int shape = current_block.shape + dshape;
    int direction = current_block.direction;
    if (shape < 0) {
        shape = 3;
    }
    else if (shape > 3) {
        shape = 0;
    }
    int i, j;
    for (i = 0; i < 4; i++) {
        for (j = 0; j < 4; j++) {
            if ((shapes[current_block.shape][i][j] >> direction) & 0x0001) {
                if (y + i >= HEIGHT || x + j < 0 || x + j >= WIDTH || board[y + i][x + j]) {
                    return 1;
                }
            }
        }
    }
    current_block.x = x;
    current_block.y = y;
    current_block.shape = shape;
    return 0;
}

int drop_block() {
    while (!move_block(0, 1, 0));
    return 1;
}

int rotate_block() {
    return move_block(0,0, 1);
}

int is_gameover() {
    return board[0][WIDTH / 2] || board[0][WIDTH / 2 + 1] || board[0][WIDTH / 2 - 1];
}

以上是一个简单的C语言俄罗斯方块的设计示例，包括视图和模型的实现。你可以根据需要进行修改和扩展。
