写一个俄罗斯方块的c语言代码

以下是一个简单的俄罗斯方块的C语言代码实现：

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

#define WIDTH 10    // 方块区域宽度
#define HEIGHT 20   // 方块区域高度

// 方块结构体
typedef struct {
    int x;  // 方块左上角x坐标
    int y;  // 方块左上角y坐标
    int shape[4][4];    // 方块形状
} Block;

// 方块区域
int board[HEIGHT][WIDTH] = { 0 };

// 方块的七种类型
int block[7][4][4] = {
    { {0,0,0,0}, {1,1,1,1}, {0,0,0,0}, {0,0,0,0} },  // I型
    { {0,0,0,0}, {0,2,2,0}, {0,2,2,0}, {0,0,0,0} },  // O型
    { {0,0,0,0}, {0,3,3,0}, {3,3,0,0}, {0,0,0,0} },  // S型
    { {0,0,0,0}, {4,4,0,0}, {0,4,4,0}, {0,0,0,0} },  // Z型
    { {0,0,0,0}, {5,5,5,0}, {0,0,5,0}, {0,0,0,0} },  // L型
    { {0,0,0,0}, {0,0,5,0}, {5,5,5,0}, {0,0,0,0} },  // J型
    { {0,0,0,0}, {0,0,6,0}, {0,6,6,6}, {0,0,0,0} }   // T型
};

// 随机生成一个方块
Block newBlock() {
    Block b;
    int type = rand() % 7;
    b.x = WIDTH / 2 - 2;
    b.y = 0;
    for (int i = 0; i < 4; i++) {
        for (int j = 0; j < 4; j++) {
            b.shape[i][j] = block[type][i][j];
        }
    }
    return b;
}

// 画出方块区域
void drawBoard() {
    system("cls");
    for (int i = 0; i < HEIGHT; i++) {
        for (int j = 0; j < WIDTH; j++) {
            if (board[i][j] == 0) {
                printf("  ");
            }
            else {
                printf("[]");
            }
        }
        printf("\n");
    }
}

// 画出方块
void drawBlock(Block b) {
    for (int i = 0; i < 4; i++) {
        for (int j = 0; j < 4; j++) {
            if (b.shape[i][j] != 0) {
                printf("[]");
            }
        }
        printf("\n");
    }
}

// 检查方块是否可以移动
int checkMove(Block b, int x, int y) {
    for (int i = 0; i < 4; i++) {
        for (int j = 0; j < 4; j++) {
            if (b.shape[i][j] != 0) {
                if (i + y >= HEIGHT || j + x < 0 || j + x >= WIDTH || board[i + y][j + x] != 0) {
                    return 0;
                }
            }
        }
    }
    return 1;
}

// 方块下落
void drop(Block b) {
    while (checkMove(b, 0, 1)) {
        b.y++;
        drawBoard();
        drawBlock(b);
        Sleep(500);
    }
    for (int i = 0; i < 4; i++) {
        for (int j = 0; j < 4; j++) {
            if (b.shape[i][j] != 0) {
                board[i + b.y][j + b.x] = b.shape[i][j];
            }
        }
    }
}

// 消除满行
void clearLine() {
    for (int i = HEIGHT - 1; i >= 0; i--) {
        int flag = 1;
        for (int j = 0; j < WIDTH; j++) {
            if (board[i][j] == 0) {
                flag = 0;
                break;
            }
        }
        if (flag) {
            for (int k = i; k > 0; k--) {
                for (int j = 0; j < WIDTH; j++) {
                    board[k][j] = board[k - 1][j];
                }
            }
            i++;
            drawBoard();
            Sleep(500);
        }
    }
}

int main() {
    srand((unsigned)time(NULL));
    Block currentBlock = newBlock();
    while (1) {
        drawBoard();
        drawBlock(currentBlock);
        if (!checkMove(currentBlock, 0, 1)) {
            drop(currentBlock);
            clearLine();
            currentBlock = newBlock();
            if (!checkMove(currentBlock, 0, 0)) {
                printf("Game Over!\n");
                break;
            }
        }
        if (_kbhit()) {
            int key = _getch();
            if (key == 75 && checkMove(currentBlock, -1, 0)) {    // 左移
                currentBlock.x--;
            }
            else if (key == 77 && checkMove(currentBlock, 1, 0)) {    // 右移
                currentBlock.x++;
            }
            else if (key == 80 && checkMove(currentBlock, 0, 1)) {    // 下移
                currentBlock.y++;
            }
            else if (key == 32) {   // 空格键，直接落地
                drop(currentBlock);
                clearLine();
                currentBlock = newBlock();
                if (!checkMove(currentBlock, 0, 0)) {
                    printf("Game Over!\n");
                    break;
                }
            }
        }
        Sleep(100);
    }
    return 0;
}

该代码使用了Windows API中的`Sleep()`函数，需要在Windows环境下编译运行。
