python 俄罗斯方块代码

好的，以下是一个简单的 Python 俄罗斯方块游戏的代码示例：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏区域大小
block_size = 30
rows = 20
cols = 10
width = block_size * cols
height = block_size * rows

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

# 创建游戏区域
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("Tetris")

# 方块类型定义
shapes = [
    [[1, 1, 1],
     [0, 1, 0]],
    [[0, 2, 2],
     [2, 2, 0]],
    [[3, 3, 0],
     [0, 3, 3]],
    [[4, 0, 0],
     [4, 4, 4]],
    [[0, 0, 5],
     [5, 5, 5]],
    [[6, 6],
     [6, 6]],
    [[7, 7, 7, 7]]
]

# 方块颜色定义
colors = [
    white,
    blue,
    green,
    red,
    (255, 165, 0),
    (128, 0, 128),
    (255, 0, 255)
]

# 初始化游戏区域
board = [[0] * cols for _ in range(rows)]

# 定义方块类
class Shape:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.type = random.randint(0, len(shapes) - 1)
        self.color = colors[self.type]
        self.shape = shapes[self.type]
        self.rotation = 0

                    pygame.draw.rect(surface, self.color, (self.x + c * block_size, self.y + r * block_size, block_size, block_size), 0)

    # 移动方块
    def move(self, dx, dy):
        self.x += dx
        self.y += dy

    # 旋转方块
    def rotate(self):
        self.rotation = (self.rotation + 1) % len(self.shape)
        self.shape = shapes[self.type][self.rotation]

    # 判断方块是否在游戏区域内
    def is_valid(self):
        for r in range(len(self.shape)):

                        return False
        return True

    # 将方块固定在游戏区域中
    def fix(self):

                    board[self.y + r][self.x + c] = self.type + 1

# 定义游戏结束函数
def game_over():
    font = pygame.font.SysFont("Arial", 60)
    text = font.render("Game Over", True, red)
    screen.blit(text, (width / 2 - text.get_width() / 2, height / 2 - text.get_height() / 2))
    pygame.display.flip()
    pygame.time.wait(2000)
    pygame.quit()
    sys.exit()

# 游戏主循环
fps = 5
clock = pygame.time.Clock()
current_shape = Shape(3 * block_size, 0)
next_shape = Shape(width + 3 * block_size, 0)

while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()

        if not current_shape.is_valid():
            game_over()

    # 绘制游戏区域
    screen.fill(black)

            pygame.draw.rect(screen, colors[board[r][c]], (c * block_size, r * block_size, block_size, block_size), 0)

    # 绘制当前方块和下一个方块
    current_shape.draw(screen)
    next_shape.draw(screen)

    pygame.display.flip()
    clock.tick(fps)

这是一个比较简单的示例代码，还有很多可以优化的地方。如果您想了解更多关于 Pygame 的内容，可以参考 Pygame 官方文档。
