用python制作一个俄罗斯方块

下面是一个简单的 Python 俄罗斯方块游戏示例，供你参考：

import pygame
import random

# 定义一些常量
SCREEN_WIDTH = 640
SCREEN_HEIGHT = 480
BLOCK_SIZE = 20
BOARD_WIDTH = 10
BOARD_HEIGHT = 20
FPS = 60
FONT_SIZE = 24
SHAPE_TYPES = [
    ((0, 0), (1, 0), (0, 1), (1, 1)),  # 方块
    ((0, 0), (-1, 0), (1, 0), (2, 0)), # 条形
    ((0, 0), (-1, 0), (0, 1), (1, 1)), # Z 形
    ((0, 0), (1, 0), (0, 1), (-1, 1)), # 反 Z 形
    ((0, 0), (0, -1), (0, 1), (1, 0)), # L 形
    ((0, 0), (0, -1), (0, 1), (-1, 0)), # 反 L 形
    ((0, 0), (-1, 0), (1, 0), (0, 1)), # T 形
]

# 定义一些颜色
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)

# 定义方块类
class Block:
    def __init__(self, shape_type, color):
        self.shape_type = shape_type
        self.color = color
        self.x = BOARD_WIDTH // 2
        self.y = 0

    def rotate(self):
        self.shape_type = [(y, -x) for x, y in self.shape_type]

    def move(self, dx, dy):
        self.x += dx
        self.y += dy

    def get_blocks(self):
        return [(self.x + x, self.y + y) for x, y in self.shape_type]

# 定义游戏主函数
def main():
    # 初始化 pygame
    pygame.init()

    # 设置窗口标题
    pygame.display.set_caption("俄罗斯方块")

    # 创建游戏窗口
    screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))

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

    # 创建时钟对象
    clock = pygame.time.Clock()

    # 创建方块列表
    blocks = []

    # 创建当前方块
    current_block = Block(random.choice(SHAPE_TYPES), random.choice([RED, GREEN, BLUE, CYAN, MAGENTA, YELLOW]))

    # 创建游戏结束标志
    game_over = False

    # 创建得分变量
    score = 0

    # 游戏循环
    while not game_over:
        # 处理事件
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                game_over = True
            elif event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    current_block.move(-1, 0)
                    if any(x < 0 for x, y in current_block.get_blocks()) or any((x, y) in blocks for x, y in current_block.get_blocks()):
                        current_block.move(1, 0)
                elif event.key == pygame.K_RIGHT:

                        current_block.rotate()
                        current_block.rotate()
                        current_block.rotate()
                elif event.key == pygame.K_DOWN:
                    current_block.move(0, 1)
                    if any(y >= BOARD_HEIGHT for x, y in current_block.get_blocks()) or any((x, y) in blocks for x, y in current_block.get_blocks()):
                        current_block.move(0, -1)

        # 计算下一帧方块位置
        next_block = Block(current_block.shape_type, current_block.color)
        next_block.move(0, 1)
        if any(y >= BOARD_HEIGHT for x, y in next_block.get_blocks()) or any((x, y) in blocks for x, y in next_block.get_blocks()):
            for x, y in current_block.get_blocks():
                if y < 0:
                    game_over = True
                    break
                blocks.append((x, y))
            current_block = Block(random.choice(SHAPE_TYPES), random.choice([RED, GREEN, BLUE, CYAN, MAGENTA, YELLOW]))
            while any((x, y) in blocks for x, y in current_block.get_blocks()):
                current_block.move(0, -1)
        else:
            current_block = next_block

        # 绘制背景
        screen.fill(BLACK)

        # 绘制方块
        for x, y in blocks:
            pygame.draw.rect(screen, WHITE, (x * BLOCK_SIZE, y * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))

        # 绘制当前方块
        for x, y in current_block.get_blocks():
            pygame.draw.rect(screen, current_block.color, (x * BLOCK_SIZE, y * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))

        # 绘制得分
        score_text = font.render("Score: %d" % score, True, WHITE)
        screen.blit(score_text, (10, 10))

        # 更新窗口
        pygame.display.update()

        # 控制帧率
        clock.tick(FPS)

    # 退出 pygame
    pygame.quit()

# 启动游戏
if __name__ == "__main__":
    main()

这个示例实现了一个简单的俄罗斯方块游戏。玩家可以使用左右箭头键移动方块，上箭头键旋转方块，下箭头键加速方块下落。游戏会根据方块堆叠情况自动清除行并增加得分。游戏结束的条件是方块堆叠到屏幕顶端。注意，这个示例可能还有一些不足之处，需要你自己进行改进。
