pythonidle模式俄罗斯方块代码

以下是用Python实现俄罗斯方块的代码：

import pygame
import random

# 初始化游戏
pygame.init()

# 设置游戏窗口大小
WIDTH = 800
HEIGHT = 600
screen = pygame.display.set_mode((WIDTH, HEIGHT))

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

# 设置字体
font = pygame.font.SysFont(None, 25)

# 定义方块大小
BLOCK_SIZE = 20

# 定义俄罗斯方块类
class Block(pygame.sprite.Sprite):
    def __init__(self, x, y, color):
        super().__init__()
        self.image = pygame.Surface([BLOCK_SIZE, BLOCK_SIZE])
        self.image.fill(color)
        self.rect = self.image.get_rect()
        self.rect.x = x
        self.rect.y = y

# 定义俄罗斯方块组类
class BlockGroup(pygame.sprite.Group):
    def __init__(self):
        super().__init__()
        self.create_block()

    # 创建新的方块
    def create_block(self):
        block_type = random.choice(['I', 'O', 'T', 'S', 'Z', 'J', 'L'])
        if block_type == 'I':
            self.add(Block(400, 0, BLUE))
            self.add(Block(400, BLOCK_SIZE, BLUE))
            self.add(Block(400, BLOCK_SIZE * 2, BLUE))
            self.add(Block(400, BLOCK_SIZE * 3, BLUE))
        elif block_type == 'O':
            self.add(Block(400, 0, GREEN))
            self.add(Block(400 + BLOCK_SIZE, 0, GREEN))
            self.add(Block(400, BLOCK_SIZE, GREEN))
            self.add(Block(400 + BLOCK_SIZE, BLOCK_SIZE, GREEN))
        elif block_type == 'T':
            self.add(Block(400, 0, RED))
            self.add(Block(400 - BLOCK_SIZE, BLOCK_SIZE, RED))
            self.add(Block(400, BLOCK_SIZE, RED))
            self.add(Block(400 + BLOCK_SIZE, BLOCK_SIZE, RED))
        elif block_type == 'S':
            self.add(Block(400, 0, BLUE))
            self.add(Block(400 + BLOCK_SIZE, 0, BLUE))
            self.add(Block(400, BLOCK_SIZE, BLUE))
            self.add(Block(400 - BLOCK_SIZE, BLOCK_SIZE, BLUE))
        elif block_type == 'Z':
            self.add(Block(400, 0, GREEN))
            self.add(Block(400 - BLOCK_SIZE, 0, GREEN))
            self.add(Block(400, BLOCK_SIZE, GREEN))
            self.add(Block(400 + BLOCK_SIZE, BLOCK_SIZE, GREEN))
        elif block_type == 'J':
            self.add(Block(400, 0, RED))
            self.add(Block(400, BLOCK_SIZE, RED))
            self.add(Block(400 - BLOCK_SIZE, BLOCK_SIZE, RED))
            self.add(Block(400 - BLOCK_SIZE, BLOCK_SIZE * 2, RED))
        elif block_type == 'L':
            self.add(Block(400, 0, BLUE))
            self.add(Block(400, BLOCK_SIZE, BLUE))
            self.add(Block(400 + BLOCK_SIZE, BLOCK_SIZE, BLUE))
            self.add(Block(400 + BLOCK_SIZE, BLOCK_SIZE * 2, BLUE))

    # 判断方块是否可以移动
    def can_move(self, x, y):
        for block in self.sprites():
            if block.rect.x + x < 0 or block.rect.x + x >= WIDTH:
                return False
            if block.rect.y + y < 0 or block.rect.y + y >= HEIGHT:
                return False
        return True

    # 移动方块
    def move(self, x, y):
        if self.can_move(x, y):
            for block in self.sprites():
                block.rect.x += x
                block.rect.y += y

    # 判断是否可以旋转
    def can_rotate(self):
        # 获取中心点
        center_x = self.sprites()[1].rect.x
        center_y = self.sprites()[1].rect.y
        # 计算旋转后的位置
        for block in self.sprites():
            delta_x = block.rect.x - center_x
            delta_y = block.rect.y - center_y
            block.rect.x = center_x - delta_y
            block.rect.y = center_y + delta_x
            if block.rect.x < 0 or block.rect.x >= WIDTH or block.rect.y < 0 or block.rect.y >= HEIGHT:
                return False
        return True

    # 旋转方块
    def rotate(self):
        if self.can_rotate():
            center_x = self.sprites()[1].rect.x
            center_y = self.sprites()[1].rect.y
            for block in self.sprites():
                delta_x = block.rect.x - center_x
                delta_y = block.rect.y - center_y
                block.rect.x = center_x - delta_y
                block.rect.y = center_y + delta_x

# 创建方块组
block_group = BlockGroup()

# 设置时钟
clock = pygame.time.Clock()

# 开始游戏循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                block_group.move(-BLOCK_SIZE, 0)
            elif event.key == pygame.K_RIGHT:
                block_group.move(BLOCK_SIZE, 0)
            elif event.key == pygame.K_DOWN:
                block_group.move(0, BLOCK_SIZE)
            elif event.key == pygame.K_UP:
                block_group.rotate()

    # 检测方块是否可以下落
    if block_group.can_move(0, BLOCK_SIZE):
        block_group.move(0, BLOCK_SIZE)
    else:
        # 方块到达底部，创建新的方块
        block_group = BlockGroup()

    # 绘制背景
    screen.fill(WHITE)

    # 绘制方块
    block_group.draw(screen)

    # 绘制分数
    score_text = font.render('Score: 0', True, BLACK)
    screen.blit(score_text, (10, 10))

    # 更新屏幕
    pygame.display.flip()

    # 设置帧率
    clock.tick(30)

# 退出游戏
pygame.quit()

这个代码可以在Python IDE的交互模式下运行，也可以保存为.py文件后运行。运行后，可以使用方向键左右移动方块，使用方向键下加速方块下落，使用方向键上旋转方块。游戏结束时，可以按ESC键退出游戏。
