使用C语言编一下俄罗斯方块的代码

好的，下面是一个简单的俄罗斯方块游戏的 C 语言代码示例：

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

#define ROW 20
#define COL 10

int board[ROW][COL] = {0};
int shapes[7][4][2] = {
    {{0, 0}, {0, 1}, {1, 0}, {1, 1}},
    {{0, 0}, {0, 1}, {0, 2}, {0, 3}},
    {{0, 0}, {1, 0}, {2, 0}, {3, 0}},
    {{0, 0}, {0, 1}, {0, 2}, {1, 2}},
    {{0, 0}, {0, 1}, {0, 2}, {1, 0}},
    {{0, 0}, {0, 1}, {0, 2}, {1, 1}},
    {{0, 0}, {1, 0}, {1, 1}, {2, 1}},
};

int cur_shape = 0;
int cur_x = 0;
int cur_y = 0;

void init() {
    srand((unsigned int)time(NULL));
    cur_shape = rand() % 7;
    cur_x = 0;
    cur_y = COL / 2 - 2;
}

void draw() {
    system("cls");
    printf("Press W/A/S/D to move, Q to quit.\n");
    for (int i = 0; i < ROW; i++) {
        for (int j = 0; j < COL; j++) {
            if (board[i][j] == 0) {
                printf(".");
            } else {
                printf("*");
            }
        }
        printf("\n");
    }
}

void move(char op) {
    switch (op) {
        case 'a':
            cur_y--;
            break;
        case 'd':
            cur_y++;
            break;
        case 's':
            cur_x++;
            break;
        case 'w':
            cur_x--;
            break;
    }
}

void merge() {
    for (int i = 0; i < 4; i++) {
        int x = cur_x + shapes[cur_shape][i][0];
        int y = cur_y + shapes[cur_shape][i][1];
        board[x][y] = 1;
    }
}

int check() {
    for (int i = 0; i < 4; i++) {
        int x = cur_x + shapes[cur_shape][i][0];
        int y = cur_y + shapes[cur_shape][i][1];
        if (x < 0 || x >= ROW || y < 0 || y >= COL) {
            return 0;
        }
        if (board[x][y] == 1) {
            return 0;
        }
    }
    return 1;
}

void update() {
    if (check()) {
        merge();
        init();
    }
}

int main() {
    init();
    while (1) {
        draw();
        if (_kbhit()) {
            char op = _getch();
            if (op == 'q') {
                break;
            }
            move(op);
        }
        update();
        Sleep(100);
    }
    return 0;
}

这是一个简单的命令行俄罗斯方块游戏，使用了 Windows.h 库中的 Sleep 函数来控制帧率。
