python俄罗斯方块小游戏

好的，我来为您介绍如何使用 Python 实现俄罗斯方块小游戏。

首先，我们需要安装 Pygame，它是一个 Python 编写的游戏库，可以用来创建游戏。

1. 安装 Pygame

可以在终端输入以下命令来安装 Pygame：

pip install pygame

2. 编写游戏代码

下面是一个简单的俄罗斯方块游戏的代码示例：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏窗口大小
size = (500, 600)
screen = pygame.display.set_mode(size)

# 游戏标题
pygame.display.set_caption("俄罗斯方块")

# 颜色定义
black = (0, 0, 0)
white = (255, 255, 255)
red = (255, 0, 0)
green = (0, 255, 0)
blue = (0, 0, 255)
gray = (128, 128, 128)

# 方块大小
block_size = 20

# 游戏区域大小
play_width = 10 * block_size
play_height = 20 * block_size

# 游戏区域位置
play_x = (size[0] - play_width) // 2
play_y = size[1] - play_height - 10

# 方块形状定义
tetrominoes = [
    [[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]]
]

# 随机生成方块
def new_piece():
    shape = random.choice(tetrominoes)
    piece = {}
    piece["shape"] = shape
    piece["color"] = random.choice([red, green, blue, gray])
    piece["x"] = play_x + play_width // 2 - len(shape[0]) // 2 * block_size
    piece["y"] = play_y - len(shape) * block_size
    return piece

# 绘制方块
def draw_piece(piece):
    shape = piece["shape"]
    color = piece["color"]
    x = piece["x"]
    y = piece["y"]
    for i in range(len(shape)):
        for j in range(len(shape[i])):
            if shape[i][j] != 0:
                pygame.draw.rect(screen, color, [x + j * block_size, y + i * block_size, block_size, block_size])

# 检测方块是否碰到边界或其他方块
def is_collision(piece, board):
    shape = piece["shape"]
    x = piece["x"]
    y = piece["y"]
    for i in range(len(shape)):
        for j in range(len(shape[i])):
            if shape[i][j] != 0:
                if x + j * block_size < play_x or \
                        x + j * block_size >= play_x + play_width or \
                        y + i * block_size >= play_y + play_height or \
                        board[(y + i * block_size - play_y) // block_size][(x + j * block_size - play_x) // block_size] != black:
                    return True
    return False

# 添加方块到游戏区域
def add_piece(piece, board):
    shape = piece["shape"]
    x = piece["x"]
    y = piece["y"]
    for i in range(len(shape)):
        for j in range(len(shape[i])):
            if shape[i][j] != 0:
                board[(y + i * block_size - play_y) // block_size][(x + j * block_size - play_x) // block_size] = piece["color"]

# 检测是否有完整的一行
def check_row(board):
    count = 0
    for i in range(len(board)):
        if black not in board[i]:
            count += 1
            board.pop(i)
            board.insert(0, [black for _ in range(10)])
    return count

# 绘制游戏区域
def draw_board(board):
    for i in range(len(board)):
        for j in range(len(board[i])):
            pygame.draw.rect(screen, board[i][j], [play_x + j * block_size, play_y + i * block_size, block_size, block_size], 0)
            pygame.draw.rect(screen, white, [play_x + j * block_size, play_y + i * block_size, block_size, block_size], 1)

# 游戏主循环
def game_loop():
    board = [[black for _ in range(10)] for _ in range(20)]
    piece = new_piece()
    clock = pygame.time.Clock()
    score = 0
    falling_speed = 0.5

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

            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    piece["x"] -= block_size
                    if is_collision(piece, board):
                        piece["x"] += block_size
                elif event.key == pygame.K_RIGHT:
                    piece["x"] += block_size
                    if is_collision(piece, board):
                        piece["x"] -= block_size
                elif event.key == pygame.K_DOWN:
                    piece["y"] += block_size
                    if is_collision(piece, board):
                        piece["y"] -= block_size
                elif event.key == pygame.K_SPACE:
                    while not is_collision(piece, board):
                        piece["y"] += block_size
                    piece["y"] -= block_size

        screen.fill(white)

        # 绘制游戏区域
        draw_board(board)

        # 绘制方块
        draw_piece(piece)

        # 判断方块是否碰到底部或其他方块
        if is_collision(piece, board):
            add_piece(piece, board)
            score += check_row(board)
            piece = new_piece()

        # 绘制分数
        font = pygame.font.SysFont(None, 25)
        text = font.render("Score: " + str(score), True, black)
        screen.blit(text, (10, 10))

        # 更新屏幕
        pygame.display.update()

        # 控制方块下落速度
        clock.tick(30)
        falling_speed += 0.002
        pygame.time.delay(10)
        piece["y"] += int(falling_speed * block_size)

# 启动游戏
game_loop()

3. 运行游戏

将上述代码保存为 Python 文件，然后在终端中进入该文件所在目录，输入以下命令运行游戏：

python 文件名.py

游戏窗口将会弹出，您就可以开始玩这个简单的俄罗斯方块游戏了。
