ccf俄罗斯方块代码python

根据提供的引用内容，我们可以使用Python和Pygame库来实现俄罗斯方块游戏。下面是一个简单的示例代码，用于模拟板块下落并更新方格图：

import pygame

# 初始化Pygame
pygame.init()

# 设置游戏窗口大小
WINDOW_WIDTH = 300
WINDOW_HEIGHT = 600
WINDOW_SIZE = (WINDOW_WIDTH, WINDOW_HEIGHT)
screen = pygame.display.set_mode(WINDOW_SIZE)

# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)

# 定义方块大小
BLOCK_SIZE = 30

# 定义方块形状
block_shape = [
    [1, 1, 0],
    [0, 1, 1],
    [0, 0, 0]
]

# 定义方格图
grid = [[0 for _ in range(10)] for _ in range(15)]

# 定义板块位置
block_x = 4
block_y = 0

# 绘制方格图
def draw_grid():
    for i in range(15):
        for j in range(10):
            if grid[i][j] == 1:
                pygame.draw.rect(screen, BLUE, (j * BLOCK_SIZE, i * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))
            else:
                pygame.draw.rect(screen, WHITE, (j * BLOCK_SIZE, i * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE), 1)

# 绘制板块
def draw_block():
    for i in range(3):
        for j in range(3):
            if block_shape[i][j] == 1:
                pygame.draw.rect(screen, RED, ((block_x + j) * BLOCK_SIZE, (block_y + i) * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))

# 判断板块是否可以下落
def can_move_down():
    for i in range(3):
        for j in range(3):
            if block_shape[i][j] == 1:
                if block_y + i + 1 >= 15 or grid[block_y + i + 1][block_x + j] == 1:
                    return False
    return True

# 更新方格图
def update_grid():
    for i in range(3):
        for j in range(3):
            if block_shape[i][j] == 1:
                grid[block_y + i][block_x + j] = 1

# 主循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

    # 绘制背景
    screen.fill(BLACK)

    # 绘制方格图和板块
    draw_grid()
    draw_block()

    # 判断板块是否可以下落
    if can_move_down():
        block_y += 1
    else:
        update_grid()
        block_x = 4
        block_y = 0
        block_shape = [
            [1, 1, 0],
            [0, 1, 1],
            [0, 0, 0]
        ]

    # 更新屏幕
    pygame.display.update()

注意：这只是一个简单的示例代码，没有处理玩家的操作、消行和得分等功能。如果你想要实现完整的俄罗斯方块游戏，需要进一步完善代码。
