python 编写俄罗斯方块小游戏

好的，下面是一个简单的Python俄罗斯方块小游戏的实现，可以使用Python标准库中的`pygame`模块进行图形化界面的开发：

import pygame
import random

# 定义方块的大小和游戏区域的大小
block_size = 30
game_width = 300
game_height = 600

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

# 定义各种形状的方块，每个方块由四个小方块组成
shapes = [
    [[1, 1, 1, 1]],
    [[1, 1], [1, 1]],
    [[1, 1, 1], [0, 1, 0]],
    [[1, 1, 0], [0, 1, 1]],
    [[0, 1, 1], [1, 1, 0]],
    [[1, 0, 0], [1, 1, 1]],
    [[0, 0, 1], [1, 1, 1]],
]

class Block:
    def __init__(self, shape):
        self.shape = shape
        self.color = random.choice([red, green, blue, yellow])
        self.x = 0
        self.y = 0

    def rotate(self):
        self.shape = list(zip(*self.shape[::-1]))

    def move_down(self):
        self.y += 1

    def move_left(self):
        self.x -= 1

    def move_right(self):
        self.x += 1

class Game:
    def __init__(self):
        self.screen = pygame.display.set_mode((game_width, game_height))
        self.clock = pygame.time.Clock()
        self.score = 0
        self.game_over = False
        self.board = [[0] * (game_width // block_size) for _ in range(game_height // block_size)]
        self.current_block = Block(random.choice(shapes))

                    pygame.draw.rect(self.screen, block.color, (block.x + j, block.y + i, 1, 1))

    def draw_board(self):
        for i, row in enumerate(self.board):
            for j, cell in enumerate(row):
                if cell != 0:
                    pygame.draw.rect(self.screen, white, (j, i, 1, 1))

    def check_collision(self, block):
        for i, row in enumerate(block.shape):
            for j, cell in enumerate(row):
                if cell == 1:
                    if i + block.y >= game_height // block_size or j + block.x < 0 or j + block.x >= game_width // block_size or self.board[i + block.y][j + block.x] != 0:
                        return True
        return False

    def add_block_to_board(self, block):
        for i, row in enumerate(block.shape):

                if cell == 1:
                    self.board[i + block.y][j + block.x] = block.color

    def remove_full_rows(self):
        new_board = [[0] * (game_width // block_size) for _ in range(game_height // block_size)]
        new_row = game_height // block_size - 1
        for i in range(game_height // block_size - 1, -1, -1):
            if sum(self.board[i]) != game_width // block_size:

                new_row -= 1
            else:

        self.board = new_board

    def run(self):
        while not self.game_over:
            self.clock.tick(10)

            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    self.game_over = True
                elif event.type == pygame.KEYDOWN:
                    if event.key == pygame.K_LEFT:
                        self.current_block.move_left()
                        if self.check_collision(self.current_block):
                            self.current_block.move_right()
                    elif event.key == pygame.K_RIGHT:
                        self.current_block.move_right()
                        if self.check_collision(self.current_block):
                            self.current_block.move_left()
                    elif event.key == pygame.K_DOWN:
                        self.current_block.move_down()
                        if self.check_collision(self.current_block):
                            self.current_block.move_up()
                    elif event.key == pygame.K_UP:
                        self.current_block.rotate()
                        if self.check_collision(self.current_block):
                            self.current_block.rotate()

            self.screen.fill(black)
            self.draw_board()
            self.draw_block(self.current_block)
            if self.check_collision(self.current_block):
                self.add_block_to_board(self.current_block)
                self.current_block = Block(random.choice(shapes))
                if self.check_collision(self.current_block):
                    self.game_over = True
            else:
                self.current_block.move_down()
            self.remove_full_rows()
            pygame.display.update()

        pygame.quit()

if __name__ == '__main__':
    pygame.init()
    game = Game()
    game.run()

这个游戏包括一个游戏类`Game`和一个方块类`Block`，其中`Game`类负责游戏逻辑和图形化界面的绘制，`Block`类负责方块的移动和变形操作。游戏的主循环中，不断更新屏幕并处理用户输入，实现了俄罗斯方块的基本功能。
