俄罗斯方块游戏是一款经典的益智游戏，通常使用编程语言Python来实现。下面是一个简单的俄罗斯方块游戏的示例代码：

<code>import pygame

import random

# 定义颜色

BLACK = (0, 0, 0)

WHITE = (255, 255, 255)

RED = (255, 0, 0)

GREEN = (0, 255, 0)

BLUE = (0, 0, 255)

CYAN = (0, 255, 255)

MAGENTA = (255, 0, 255)

YELLOW = (255, 255, 0)

ORANGE = (255, 165, 0)

# 定义方块的形状

SHAPES = [

[[1, 1, 1, 1]],

[[1, 1], [1, 1]],

[[1, 1, 0], [0, 1, 1]],

[[0, 1, 1], [1, 1, 0]],

[[1, 0, 0], [1, 1, 1]],

[[0, 0, 1], [1, 1, 1]],

[[1, 1, 1], [0, 1, 0]]

]

# 初始化游戏

pygame.init()

# 设置屏幕宽高

SCREEN_WIDTH = 800

SCREEN_HEIGHT = 600

screen = pygame.display.set_mode([SCREEN_WIDTH, SCREEN_HEIGHT])

pygame.display.set_caption("俄罗斯方块")

# 定义方块的大小和间隙

block_size = 30

block_gap = 2

# 初始化方块的位置

x_pos = 3

y_pos = 0

# 初始化方块的形状

shape = random.choice(SHAPES)

# 初始化方块的颜色

color = random.choice([RED, GREEN, BLUE, CYAN, MAGENTA, YELLOW, ORANGE])

# 设置游戏时钟

clock = pygame.time.Clock()

# 判断方块是否可以移动

def can_move(x_offset, y_offset):

for i in range(len(shape)):

for j in range(len(shape[i])):

if shape[i][j]:

x = x_pos + j + x_offset

y = y_pos + i + y_offset

if (x < 0 or x >= SCREEN_WIDTH // (block_size + block_gap) or

y >= SCREEN_HEIGHT // (block_size + block_gap) or

grid[y][x]):

return False

return True

# 绘制方块

def draw_block(x, y, color):

pygame.draw.rect(screen, color, [(block_size + block_gap) * x,

(block_size + block_gap) * y,

block_size,

block_size])

# 绘制网格

for i in range(len(shape)):

for j in range(len(shape[i])):

if shape[i][j]:

x = x_pos + j

y = y_pos + i

if y >= 0:

grid[y][x] = color

# 消除行

def clear_rows():

full_rows = []

for i in range(len(grid)):

if all(grid[i]):

full_rows.append(i)

for row in full_rows:

del grid[row]

grid.insert(0, [BLACK] * (SCREEN_WIDTH // (block_size + block_gap)))

# 初始化网格

grid = [[BLACK] * (SCREEN_WIDTH // (block_size + block_gap))

for _ in range(SCREEN_HEIGHT // (block_size + block_gap))]

# 游戏主循环

running = True

while running:

for event in pygame.event.get():

if event.type == pygame.QUIT:

running = False

elif event.type == pygame.KEYDOWN:

if event.key == pygame.K_LEFT and can_move(-1, 0):

update_grid(-1, 0)

elif event.key == pygame.K_RIGHT and can_move(1, 0):

update_grid(1, 0)

elif event.key == pygame.K_DOWN and can_move(0, 1):

update_grid(0, 1)

elif can_move(-1, 0):

update_grid(-1, 0)

shape = rot_shape

elif can_move(1, 0):

update_grid(1, 0)

shape = rot_shape

update_grid(0, 1)

else:

clear_rows()

x_pos = 3

y_pos = 0

# 绘制背景

screen.fill(BLACK)

# 绘制方块

for i in range(len(shape)):

for j in range(len(shape[i])):

if shape[i][j]:

draw_block(x_pos + j, y_pos + i, color)

# 绘制网格

draw_grid(grid)

# 设置帧率

clock.tick(5)

# 更新屏幕

pygame.display.flip()

# 退出游戏

pygame.quit()

这段代码使用了Pygame库来实现游戏的图形界面，通过键盘控制方块的移动和旋转。游戏循环不断更新方块的位置和网格状态，并绘制在屏幕上。在方块达到底部或无法继续移动时，判断是否有满行，并清除满行的方块。游戏会根据方块的状态和移动情况不断更新，直到无法继续下落为止，游戏结束。

请注意，这只是一个简单的示例，可能还有一些功能和优化方面的改进。您可以根据自己的需求进行修改和扩展。
