如何利用python制作俄罗斯方块

要制作俄罗斯方块游戏，可以使用 Python 的 Pygame 库来实现。

首先需要安装 Pygame 库，可以使用 pip 命令在命令行中安装：

pip install pygame

接下来，可以按照以下步骤来制作俄罗斯方块游戏：

1. 导入 Pygame 库和其他必要的库：

import pygame
import random

2. 初始化 Pygame：

pygame.init()

3. 设置游戏窗口的大小和标题：

screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("Tetris")

4. 定义方块的形状和颜色：

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]]
]

colors = [
    (0, 0, 0),
    (255, 0, 0),
    (0, 255, 0),
    (0, 0, 255),
    (255, 255, 0),
    (255, 0, 255),
    (0, 255, 255)
]

5. 定义方块和游戏板的类：

class Block:
    def __init__(self, x, y, shape):
        self.x = x
        self.y = y
        self.shape = shape
        self.color = random.randint(1, 6)
        self.rotation = 0

class Board:
    def __init__(self, width, height):
        self.width = width
        self.height = height
        self.grid = [[0 for y in range(height)] for x in range(width)]

    def is_valid_position(self, block):
        for x in range(2):
            for y in range(3):
                if block.shape[block.rotation][y][x] != 0:
                    if block.x + x < 0 or block.x + x >= self.width or block.y + y >= self.height or self.grid[block.x + x][block.y + y] != 0:
                        return False
        return True

    def add_block(self, block):
        for x in range(2):
            for y in range(3):
                if block.shape[block.rotation][y][x] != 0:
                    self.grid[block.x + x][block.y + y] = block.color

6. 定义游戏循环：

board = Board(10, 20)
clock = pygame.time.Clock()
fall_time = 0
current_block = Block(4, 0, shapes[random.randint(0, len(shapes) - 1)])

while True:
    # 处理游戏事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

    # 更新方块位置
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        current_block.x -= 1
        if not board.is_valid_position(current_block):
            current_block.x += 1
    elif keys[pygame.K_RIGHT]:
        current_block.x += 1
        if not board.is_valid_position(current_block):
            current_block.x -= 1
    elif keys[pygame.K_DOWN]:
        current_block.y += 1
        if not board.is_valid_position(current_block):
            current_block.y -= 1
    elif keys[pygame.K_UP]:
        current_block.rotation = (current_block.rotation + 1) % len(current_block.shape)
        if not board.is_valid_position(current_block):
            current_block.rotation = (current_block.rotation - 1) % len(current_block.shape)

    # 计算方块下落时间
    fall_delay = 1000 - (score * 10)
    if fall_time > fall_delay:
        current_block.y += 1
        if not board.is_valid_position(current_block):
            current_block.y -= 1
            board.add_block(current_block)
            current_block = Block(4, 0, shapes[random.randint(0, len(shapes) - 1)])
        fall_time = 0

    # 绘制游戏界面
    screen.fill((255, 255, 255))
    for x in range(board.width):
        for y in range(board.height):
            pygame.draw.rect(screen, colors[board.grid[x][y]], (x * 30, y * 30, 30, 30), 0)
    for x in range(2):
        for y in range(3):
            if current_block.shape[current_block.rotation][y][x] != 0:
                pygame.draw.rect(screen, colors[current_block.color], ((current_block.x + x) * 30, (current_block.y + y) * 30, 30, 30), 0)
    pygame.display.update()

    # 更新游戏时间
    fall_time += clock.tick(60)

这样，一个简单的俄罗斯方块游戏就完成了。你可以根据自己的需求进行修改和扩展。
