用python制作俄罗斯方块小游戏

好的，制作俄罗斯方块小游戏可以使用 Python 的 Pygame 模块。以下是一个简单的示例代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏区域大小
screen_width = 400
screen_height = 600

# 方块大小
block_size = 20

# 颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)
green = (0, 255, 0)
blue = (0, 0, 255)

# 创建游戏窗口
game_display = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption('俄罗斯方块')

# 创建字体对象
font = pygame.font.SysFont(None, 25)

# 定义方块类
class Block:
    def __init__(self, x, y, color):
        self.x = x
        self.y = y
        self.color = color

    def draw(self):
        pygame.draw.rect(game_display, self.color, [self.x, self.y, block_size, block_size])

# 定义方块组类
class BlockGroup:
    def __init__(self):
        self.blocks = []

    def add_block(self, block):
        self.blocks.append(block)

    def draw(self):
        for block in self.blocks:
            block.draw()

    def move(self, x, y):
        for block in self.blocks:
            block.x += x
            block.y += y

    def get_left_edge(self):
        left_edge = screen_width
        for block in self.blocks:
            if block.x < left_edge:
                left_edge = block.x
        return left_edge

    def get_right_edge(self):
        right_edge = 0
        for block in self.blocks:
            if block.x > right_edge:
                right_edge = block.x
        return right_edge

    def get_bottom_edge(self):
        bottom_edge = 0
        for block in self.blocks:
            if block.y > bottom_edge:
                bottom_edge = block.y
        return bottom_edge

    def remove_full_lines(self):
        bottom_edge = self.get_bottom_edge()
        full_lines = []
        for y in range(0, bottom_edge + block_size, block_size):
            line_blocks = [block for block in self.blocks if block.y == y]
            if len(line_blocks) == screen_width // block_size:
                full_lines.append(y)
                for block in line_blocks:
                    self.blocks.remove(block)
        if full_lines:
            for y in range(max(full_lines) - block_size, -1, -block_size):
                line_blocks = [block for block in self.blocks if block.y == y]
                for block in line_blocks:
                    block.y += len(full_lines) * block_size

# 定义游戏主循环
def game_loop():
    # 创建方块组对象
    block_group = BlockGroup()

    # 创建当前方块对象和下一个方块对象
    current_block = None
    next_block = Block(screen_width // 2 - block_size, 0, random.choice([red, green, blue]))

    # 初始化得分和速度
    score = 0
    speed = 1

    # 游戏循环标志
    game_exit = False

    while not game_exit:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                game_exit = True
            elif event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    if block_group.get_left_edge() > 0:
                        block_group.move(-block_size, 0)
                elif event.key == pygame.K_RIGHT:
                    if block_group.get_right_edge() < screen_width - block_size:
                        block_group.move(block_size, 0)
                elif event.key == pygame.K_DOWN:
                    speed = 5
                elif event.key == pygame.K_SPACE:
                    current_block = None

        # 清屏，绘制背景
        game_display.fill(white)

        # 绘制得分
        score_text = font.render('Score: ' + str(score), True, black)
        game_display.blit(score_text, [10, 10])

        # 绘制下一个方块
        next_text = font.render('Next:', True, black)
        game_display.blit(next_text, [screen_width - 70, 10])
        pygame.draw.rect(game_display, next_block.color, [screen_width - 60, 30, block_size, block_size])
        pygame.draw.rect(game_display, next_block.color, [screen_width - 40, 30, block_size, block_size])
        pygame.draw.rect(game_display, next_block.color, [screen_width - 20, 30, block_size, block_size])

        # 绘制当前方块组
        if current_block:
            block_group.add_block(current_block)
        block_group.draw()

        # 如果没有当前方块，则创建新的方块
        if not current_block:
            current_block = Block(screen_width // 2 - block_size, 0, next_block.color)
            next_block = Block(screen_width // 2 - block_size, 0, random.choice([red, green, blue]))

        # 如果当前方块到达底部，则将其添加到方块组，清空当前方块
        if current_block.y + block_size >= screen_height or \
                any([block for block in block_group.blocks if block.x == current_block.x and block.y == current_block.y + block_size]):
            block_group.add_block(current_block)
            current_block = None

        # 移动当前方块
        if current_block:
            current_block.y += speed

        # 移除满行
        block_group.remove_full_lines()
        if len(block_group.blocks) > 0 and block_group.get_bottom_edge() >= screen_height:
            game_display.fill(white)
            game_over_text = font.render('Game Over!', True, black)
            game_display.blit(game_over_text, [screen_width // 2 - 50, screen_height // 2 - 12])
            pygame.display.update()
            pygame.time.wait(2000)
            game_exit = True

        # 更新屏幕
        pygame.display.update()

        # 控制游戏速度
        pygame.time.wait(50)

    # 退出 Pygame
    pygame.quit()

# 启动游戏循环
game_loop()

这个示例代码可能还有一些问题，比如方块组移动时没有判断是否与其他方块重叠，方块的样式比较单一等等，但是可以作为一个简单的起点来制作俄罗斯方块小游戏。
