python 俄罗斯方块

Python 语言可以实现俄罗斯方块游戏，可以使用 Pygame 游戏开发库来实现。以下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
WINDOW_WIDTH = 600
WINDOW_HEIGHT = 800

# 方块大小
BLOCK_SIZE = 30

# 方块种类及其形状
BLOCKS = [
    [
        [(0,0,1), (1,0,1), (1,1,1)],
        [(1,1,0), (1,0,0), (1,0,0)],
        [(1,1,1), (1,0,0), (0,0,0)],
        [(0,1,0), (0,1,0), (1,1,0)]
    ],
    [
        [(0,2,0), (0,2,0), (2,2,0)],
        [(2,0,0), (2,2,0), (2,0,0)],
        [(2,2,0), (0,2,0), (0,2,0)],
        [(0,0,0), (2,2,0), (0,2,2)]
    ],
    [
        [(3,3,0), (0,3,3), (0,0,0)],
        [(0,3,0), (3,3,0), (3,0,0)],
        [(0,0,0), (3,3,0), (0,3,3)],
        [(0,3,0), (3,3,0), (3,0,0)]
    ],
    [
        [(0,4,4), (4,4,0), (0,0,0)],
        [(4,0,0), (4,4,0), (0,4,0)],
        [(0,0,0), (0,4,4), (4,4,0)],
        [(4,0,0), (4,4,0), (0,4,0)]
    ],
    [
        [(5,5,5,5)],
        [(5,0,0,0), (5,0,0,0), (5,0,0,0), (5,0,0,0)],
        [(5,5,5,5)],
        [(5,0,0,0), (5,0,0,0), (5,0,0,0), (5,0,0,0)]
    ]
]

# 方块种类数量
BLOCK_TYPES = len(BLOCKS)

# 游戏区域大小
GAME_AREA_WIDTH = BLOCK_SIZE * 10
GAME_AREA_HEIGHT = BLOCK_SIZE * 20

# 游戏区域左上角坐标
GAME_AREA_X = int((WINDOW_WIDTH - GAME_AREA_WIDTH) / 2)
GAME_AREA_Y = int((WINDOW_HEIGHT - GAME_AREA_HEIGHT) / 2)

# 颜色列表
COLORS = [
    (0,0,0),
    (255,0,0),
    (0,255,0),
    (0,0,255),
    (255,255,0),
    (255,0,255),
    (0,255,255),
    (255,255,255)
]

# 创建游戏窗口
window = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))

# 创建游戏区域表格
game_area = [[0] * 10 for i in range(20)]

# 当前方块位置及形状
cur_block_x = 4
cur_block_y = 0
cur_block_type = random.randint(0, BLOCK_TYPES - 1)
cur_block_rotation = 0

# 下落速度
speed = 10
clock = pygame.time.Clock()

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

    # 处理键盘输入
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        cur_block_x -= 1
    elif keys[pygame.K_RIGHT]:
        cur_block_x += 1
    elif keys[pygame.K_DOWN]:
        cur_block_y += 1
    elif keys[pygame.K_UP]:
        cur_block_rotation = (cur_block_rotation + 1) % 4

    # 绘制游戏区域
    window.fill(COLORS[0])
    for i in range(10):
        for j in range(20):
            if game_area[j][i] != 0:
                pygame.draw.rect(window, COLORS[game_area[j][i]], (GAME_AREA_X + i * BLOCK_SIZE, GAME_AREA_Y + j * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))

    # 绘制当前方块
    cur_block = BLOCKS[cur_block_type][cur_block_rotation]
    for i in range(3):
        for j in range(3):
            if cur_block[i][j] != 0:
                pygame.draw.rect(window, COLORS[cur_block[i][j]], (GAME_AREA_X + (cur_block_x + j) * BLOCK_SIZE, GAME_AREA_Y + (cur_block_y + i) * BLOCK_SIZE, BLOCK_SIZE, BLOCK_SIZE))

    # 检查是否可以下落方块
    can_move = True
    for i in range(3):
        for j in range(3):
            if cur_block[i][j] != 0:
                if cur_block_y + i >= 20 or game_area[cur_block_y + i][cur_block_x + j] != 0:
                    can_move = False
                    break
        if not can_move:
            break

    # 下落方块
    if can_move:
        cur_block_y += 1
    else:
        # 将方块加入游戏区域
        for i in range(3):
            for j in range(3):
                if cur_block[i][j] != 0:
                    game_area[cur_block_y + i][cur_block_x + j] = cur_block_type + 1

        # 生成新方块
        cur_block_x = 4
        cur_block_y = 0
        cur_block_type = random.randint(0, BLOCK_TYPES - 1)
        cur_block_rotation = 0

        # 检查是否有满行
        for i in range(20):
            if sum(game_area[i]) == 10:
                # 删除满行
                for j in range(i, 0, -1):
                    game_area[j] = game_area[j-1].copy()
                game_area[0] = [0] * 10

    # 更新屏幕
    pygame.display.update()

    # 控制下落速度
    clock.tick(speed)

这段代码使用 Pygame 创建游戏窗口，并在游戏区域中绘制方块。游戏中的方块有多种形状，可以在游戏循环中不断地下落，并且可以通过键盘控制方块的移动和旋转。当方块落到底部或与其他方块重叠时，将其加入游戏区域，并检查是否有满行需要消除。这样就实现了一个简单的俄罗斯方块游戏。
