用Python写一个连连看小游戏

A：

用Python实现一个连连看小游戏可以分为以下几个步骤：

1. 安装 Pygame 库

Pygame 是 Python 的一个游戏库，提供了丰富的游戏开发工具和接口。

在终端中使用以下命令安装 Pygame：

pip install pygame

2. 准备游戏素材

连连看游戏需要的素材有图片和声音。可以在游戏素材网站上下载，并按需修改。

素材可以放在游戏目录下的某个文件夹中。

3. 编写游戏代码

首先，我们需要导入 Pygame 库和一些必要的模块：

import pygame
from pygame.locals import *
import sys
import random
import time

然后，我们需要定义一些全局变量和常量：

WINDOW_WIDTH = 800
WINDOW_HEIGHT = 600
FPS = 30
BLOCK_SIZE = 60
ROW_NUM = 8
COL_NUM = 10

接下来，我们需要编写游戏初始化函数。这个函数会初始化 Pygame 引擎，并加载游戏所需的素材：

def initialize():
    pygame.init()
    pygame.mixer.init()
    pygame.display.set_caption("连连看")
    window_surface = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
    clock = pygame.time.Clock()
    pygame.key.set_repeat(1, 100)
    background_image = pygame.image.load("background.jpg").convert()
    block_images = []
    for i in range(1, 9):
        image = pygame.image.load("block{0}.png".format(i)).convert_alpha()
        image = pygame.transform.scale(image, (BLOCK_SIZE, BLOCK_SIZE))
        block_images.append(image)
    click_sound = pygame.mixer.Sound("click.wav")
    eliminate_sound = pygame.mixer.Sound("eliminate.wav")
    return window_surface, clock, background_image, block_images, click_sound, eliminate_sound

接下来，我们需要编写游戏主循环函数。在这个函数中，我们会实现游戏的逻辑和交互，包括生成随机的方块，监听用户输入，判断是否消除方块，更新游戏界面，并播放声音。

def main_loop(window_surface, clock, background_image, block_images, click_sound, eliminate_sound):
    random.seed(time.time())
    blocks = []
    for row in range(ROW_NUM):
        blocks.append([])
        for col in range(COL_NUM):
            block_type = random.randint(0, len(block_images) - 1)
            block_image = block_images[block_type]
            block_rect = block_image.get_rect()
            x = (col + 0.5) * BLOCK_SIZE
            y = (row + 0.5) * BLOCK_SIZE
            block_rect.center = (x, y)
            block_dict = {"type": block_type,
                          "image": block_image,
                          "rect": block_rect}
            blocks[row].append(block_dict)
    selected = None
    while True:
        for event in pygame.event.get():
            if event.type == QUIT:
                pygame.quit()
                sys.exit()
            elif event.type == KEYDOWN:
                if event.key == K_ESCAPE:
                    pygame.quit()
                    sys.exit()
            elif event.type == MOUSEBUTTONDOWN:
                click_sound.play()
                pos = pygame.mouse.get_pos()
                row, col = pos_to_row_col(pos)
                if row is not None and col is not None:
                    if selected is None:
                        selected = (row, col)
                    else:
                        row1, col1 = selected
                        row2, col2 = row, col
                        if can_eliminate(blocks, row1, col1, row2, col2):
                            eliminate_sound.play()
                            blocks[row1][col1] = None
                            blocks[row2][col2] = None
                        selected = None
        window_surface.blit(background_image, (0, 0))
        for row in range(ROW_NUM):
            for col in range(COL_NUM):
                block = blocks[row][col]
                if block is not None:
                    block_rect = block["rect"]
                    block_image = block["image"]
                    window_surface.blit(block_image, block_rect)
        if selected is not None:
            row, col = selected
            block_rect = blocks[row][col]["rect"]
            pygame.draw.rect(window_surface, (255, 0, 0), block_rect, 3)
        pygame.display.update()
        clock.tick(FPS)

在游戏主循环函数中，我们使用了一些帮助函数：

def pos_to_row_col(pos):
    x, y = pos
    col = int(x / BLOCK_SIZE)
    row = int(y / BLOCK_SIZE)
    if 0 <= row < ROW_NUM and 0 <= col < COL_NUM:
        return row, col
    else:
        return None, None

def can_eliminate(blocks, row1, col1, row2, col2):
    if row1 == row2 and col1 == col2:
        return False
    if blocks[row1][col1]["type"] != blocks[row2][col2]["type"]:
        return False
    if blocks[row1][col1] is None or blocks[row2][col2] is None:
        return False
    if is_blocked(blocks, row1, col1, row2, col2):
        return False
    return True

def is_blocked(blocks, row1, col1, row2, col2):
    if row1 == row2:
        return not is_path_empty(blocks, row1, min(col1, col2) + 1, max(col1, col2))
    elif col1 == col2:
        return not is_path_empty(blocks, min(row1, row2) + 1, col1, max(row1, row2))
    else:
        return is_blocked(blocks, row1, col1, row2, col1) or is_blocked(blocks, row2, col1, row2, col2)

def is_path_empty(blocks, row, col1, col2):
    if col1 > col2:
        col1, col2 = col2, col1
    for col in range(col1, col2 + 1):
        if blocks[row][col] is not None:
            return False
    return True

4. 运行游戏

最后，我们在主程序中调用初始化函数和游戏主循环函数，就可以运行游戏了：

def main():
    window_surface, clock, background_image, block_images, click_sound, eliminate_sound = initialize()
    main_loop(window_surface, clock, background_image, block_images, click_sound, eliminate_sound)

if __name__ == "__main__":
    main()
