使用python语言制作俄罗斯方块的示例代码

下面是一个简单的Python代码示例，用于制作俄罗斯方块游戏：

import pygame
import random

# 初始化pygame
pygame.init()

# 设置游戏窗口大小
screen_width = 800
screen_height = 600
game_display = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption('Tetris')

# 定义方块大小和颜色
block_size = 30
color_list = [(0, 0, 0), (255, 0, 0), (0, 255, 0), (0, 0, 255), (255, 255, 0), (255, 0, 255), (0, 255, 255), (255, 255, 255)]

# 定义方块形状
tetrominoes = [
    [[1, 1, 1], [0, 1, 0]],
    [[0, 2, 2], [2, 2, 0]],
    [[3, 3], [3, 3]],
    [[4, 4, 0], [0, 4, 4]],
    [[5, 5, 5, 5]],
    [[6, 6, 6], [0, 0, 6]],
    [[7, 7, 7], [7, 0, 0]]
]

def draw_block(x, y, color):
    pygame.draw.rect(game_display, color, (x, y, block_size, block_size))

def new_block():
    global current_block, next_block
    current_block = next_block
    next_block = random.choice(tetrominoes)

def draw_board(board):
    for row in range(20):
        for col in range(10):
            draw_block(col * block_size, row * block_size, color_list[board[row][col]])

def check_collision(board, block, x, y):
    for row in range(len(block)):
        for col in range(len(block[0])):
            if block[row][col] and board[row+y][col+x]:
                return True
    return False

def rotate_block(block):
    return [[block[y][x] for y in range(len(block))] for x in range(len(block[0])-1, -1, -1)]

# 初始化游戏板
board = [[0 for _ in range(10)] for _ in range(20)]

# 初始化当前方块和下一个方块
current_block = random.choice(tetrominoes)
next_block = random.choice(tetrominoes)

# 初始化方块位置和速度
current_x, current_y = 3, 0
fall_speed = 0.5
fall_time = 0

# 游戏循环
while True:
    # 处理游戏事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT and not check_collision(board, current_block, current_x-1, current_y):
                current_x -= 1
            elif event.key == pygame.K_RIGHT and not check_collision(board, current_block, current_x+1, current_y):
                current_x += 1
            elif event.key == pygame.K_DOWN and not check_collision(board, current_block, current_x, current_y+1):
                current_y += 1
            elif event.key == pygame.K_UP:
                current_block = rotate_block(current_block)
                if check_collision(board, current_block, current_x, current_y):
                    current_block = rotate_block(current_block)
            elif event.key == pygame.K_SPACE:
                while not check_collision(board, current_block, current_x, current_y+1):
                    current_y += 1

    # 更新方块下落位置
    fall_time += pygame.time.get_ticks() / 1000
    if fall_time >= fall_speed:
        fall_time = 0
        if not check_collision(board, current_block, current_x, current_y+1):
            current_y += 1
        else:
            # 当前方块落到底部，将其固定在游戏板上
            for row in range(len(current_block)):
                for col in range(len(current_block[0])):
                    if current_block[row][col]:
                        board[row+current_y][col+current_x] = current_block[row][col]
            # 消除满行
            for row in range(len(board)):
                if all(board[row]):
                    del board[row]
                    board.insert(0, [0 for _ in range(10)])
            # 生成新方块
            new_block()
            current_x, current_y = 3, 0

    # 绘制游戏界面
    game_display.fill(color_list[0])
    draw_board(board)
    for row in range(len(current_block)):
        for col in range(len(current_block[0])):
            if current_block[row][col]:
                draw_block((current_x+col) * block_size, (current_y+row) * block_size, color_list[current_block[row][col]])
    pygame.display.update()

这个代码示例使用了pygame模块制作了一个简单的俄罗斯方块游戏，并实现了方块的下落、移动、旋转、消除等功能。你可以根据自己的需求进行修改和扩展。
