用c语言写俄罗斯方块

使用C语言编写俄罗斯方块的代码示例如下：

#include <stdio.h>
#include <stdbool.h>

#define HEIGHT 20
#define WIDTH 10

int board[HEIGHT][WIDTH] = {0};

typedef struct {
    int x;
    int y;
} Point;

typedef struct {
    Point blocks[4];
} Tetromino;

Tetromino tetrominos[7] = {
    // I
    {{{0, 0}, {0, 1}, {0, 2}, {0, 3}}},
    // J
    {{{0, 0}, {1, 0}, {1, 1}, {1, 2}}},
    // L
    {{{0, 2}, {1, 0}, {1, 1}, {1, 2}}},
    // O
    {{{0, 0}, {0, 1}, {1, 0}, {1, 1}}},
    // S
    {{{0, 1}, {0, 2}, {1, 0}, {1, 1}}},
    // T
    {{{0, 0}, {0, 1}, {0, 2}, {1, 1}}},
    // Z
    {{{0, 0}, {0, 1}, {1, 1}, {1, 2}}},
};

bool is_valid_move(Tetromino tetromino, int x, int y) {
    for (int i = 0; i < 4; i++) {
        int new_x = x + tetromino.blocks[i].x;        int new_y = y + tetromino.blocks[i].y;

        // Check if block is out of bounds
        if (new_x < 0 || new_x >= WIDTH || new_y < 0 || new_y >= HEIGHT) {
            return false;
        }

        // Check if block collides with another block
        if (board[new_y][new_x] != 0) {
            return false;
        }
    }
    return true;
}

void place_tetromino(Tetromino tetromino, int x, int y) {
    for (int i = 0; i < 4; i++) {
        int new_x = x + tetromino.blocks[i].x;
        int new_y = y + tetromino.blocks[i].y;

        board[new_y][new_x] = 1;
    }
}

void print_board() {
    for (int i = 0; i < HEIGHT; i++) {
        for (int j = 0; j < WIDTH; j++) {
            if (board[i][j] == 0) {
                printf(" ");
            } else {
                printf("■");
            }
        }
        printf("\n");
    }
}

int main() {
    Tetromino current_tetromino = tetrominos[0];
    int x = 4;
    int y = 0;

    while (true) {
        // Check if current position is valid
        if (!is_valid_move(current_tetromino, x, y)) {
            // Place tetromino on the board
            place_tetromino(current_tetromino, x, y);
            
            // Check for completed lines and remove them
            // ...

            // Spawn a new tetromino
            current_tetromino = tetrominos[1];
            x = 4;
            y = 0;
        }

        // Update game state
        // ...

        // Render game state
        print_board();
    }

    return 0;
}
