用c语言写一个俄罗斯方块的小游戏

好的，以下是一个简单的俄罗斯方块游戏的 C 语言代码：

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

#define WIDTH 10  // 游戏区宽度
#define HEIGHT 20  // 游戏区高度
#define MAX_BLOCK 7  // 最大方块种类数

char game[HEIGHT][WIDTH];  // 游戏区
int score;  // 得分

// 从 x, y 开始画一个颜色为 c 的方块
void draw_block(int x, int y, int c) {
    HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);
    COORD pos = { x * 2, y };
    SetConsoleCursorPosition(hOut, pos);
    SetConsoleTextAttribute(hOut, c);
    printf("[]");
}

// 画出游戏区
void draw_game() {
    int i, j;
    system("cls");
    for (i = 0; i < HEIGHT; i++)
        for (j = 0; j < WIDTH; j++)
            draw_block(j, i, game[i][j]);
    printf("Score: %d\n", score);
}

// 移动方块
void move_block(int sx, int sy, int ex, int ey) {
    game[ey][ex] = game[sy][sx];
    game[sy][sx] = ' ';
}

// 旋转方块
void rotate_block(char block[][4], char new_block[][4]) {
    int i, j;
    for (i = 0; i < 4; i++)
        for (j = 0; j < 4; j++)
            new_block[i][j] = block[3 - j][i];
}

// 判断是否出界或碰到别的方块
int check(int sx, int sy, char block[][4]) {
    int i, j, x, y;
    for (i = 0, y = sy; i < 4; i++, y++)
        for (j = 0, x = sx; j < 4; j++, x++)
            if (block[i][j] != ' ' && (x < 0 || x >= WIDTH || y >= HEIGHT || game[y][x] != ' '))
                return 0;
    return 1;
}

// 判断是否可以消行
void check_line() {
    int i, j, k;
    for (i = HEIGHT - 1; i >= 0; i--) {
        for (j = 0; j < WIDTH; j++)
            if (game[i][j] == ' ') break;
        if (j == WIDTH) {
            for (k = i; k > 0; k--)
                memcpy(game[k], game[k - 1], WIDTH);
            memset(game[0], ' ', WIDTH);
            score++;
            i++;
            draw_game();
        }
    }
}
