俄罗斯方块代码：使用 Python 实现经典游戏

俄罗斯方块是一种经典的游戏，以下是一个简单的俄罗斯方块代码示例（使用 Python 语言）：

import pygame
import random

# 游戏窗口大小
WIDTH = 800
HEIGHT = 600

# 方块大小
BLOCK_SIZE = 30

# 方块颜色
COLORS = [(0, 0, 0), (255, 0, 0), (0, 255, 0), (0, 0, 255), (255, 255, 0), (255, 0, 255), (0, 255, 255), (255, 165, 0)]

# 游戏区域大小
BOARD_WIDTH = 10
BOARD_HEIGHT = 20

# 游戏区域位置
BOARD_X = (WIDTH - BLOCK_SIZE * BOARD_WIDTH) // 2
BOARD_Y = HEIGHT - BLOCK_SIZE * BOARD_HEIGHT

# 方块形状
SHAPES = [
    [[1, 1, 1, 1]],
    [[1, 1], [1, 1]],
    [[1, 1, 0], [0, 1, 1]],
    [[0, 1, 1], [1, 1, 0]],
    [[1, 1, 1], [0, 1, 0]],
    [[1, 1, 1], [1, 0, 0]],
    [[1, 1, 1], [0, 0, 1]]
]

def create_block():
    shape = random.choice(SHAPES)
    color = random.randint(1, len(COLORS) - 1)
    return shape, color

def draw_block(screen, x, y, color):
    pygame.draw.rect(screen, COLORS[color], (BOARD_X + x * BLOCK_SIZE, BOARD_Y + y * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))

            if board[y][x] != 0:
                draw_block(screen, x, y, board[y][x])

                    return True
    return False

            if shape[row][col] != 0:
                board[y + row][x + col] = shape[row][col]

def remove_lines(board):
    full_lines = []
    for row in range(BOARD_HEIGHT):
        if all(board[row]):
            full_lines.append(row)
    for row in full_lines:
        del board[row]
        board.insert(0, [0] * BOARD_WIDTH)
    return len(full_lines)

def main():
    pygame.init()
    screen = pygame.display.set_mode((WIDTH, HEIGHT))
    pygame.display.set_caption('俄罗斯方块')
    clock = pygame.time.Clock()

    board = [[0] * BOARD_WIDTH for _ in range(BOARD_HEIGHT)]
    shape, color = create_block()
    x, y = BOARD_WIDTH // 2 - len(shape[0]) // 2, 0

    game_over = False
    while not game_over:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:

                    x -= 1
                elif event.key == pygame.K_RIGHT and not check_collision(board, shape, x + 1, y):
                    x += 1
                elif event.key == pygame.K_DOWN and not check_collision(board, shape, x, y + 1):

            if check_collision(board, shape, x, y):

        pygame.display.flip()
        clock.tick(10)

    pygame.quit()

if __name__ == '__main__':
    main()

请注意，这只是一个简单的示例，可能还有其他的优化和功能可以添加。
