一、环境要求

windows系统，python3.6+ pip21+

开发环境搭建地址

一起来学pygame吧游戏开发30例（开篇词）——环境搭建+游戏效果展示

安装游戏依赖模块
pip install pygame

二、游戏简介

消消乐应该大家都玩过，或者看过。这个花里胡哨的小游戏

用python的pygame来实现，很简单。

今天带大家，用Python来实现一下这个花里胡哨的小游戏。

三、完整开发流程

1、项目主结构

首先，先整理一下项目的主结构，其实看一下主结构，基本就清晰了


modules：相关定义的Python类位置
——game.py:主模块
 
res：存放引用到的图片、音频等等
——audios:音频资源
——imgs:图片资源
——fonts：字体
 
cfg.py：为主配置文件
 
xxls.py：主程序文件
 
requirements.txt：需要引入的python依赖包

2、详细配置

cfg.py

配置文件中，需要引入os模块，并且配置打开游戏的屏幕大小。


'''主配置文件'''
import os
 
'''屏幕设置大小'''
SCREENSIZE = (700, 700)
'''元素尺寸'''
NUMGRID = 8
GRIDSIZE = 64
XMARGIN = (SCREENSIZE[0] - GRIDSIZE * NUMGRID) // 2
YMARGIN = (SCREENSIZE[1] - GRIDSIZE * NUMGRID) // 2
'''获取根目录'''
ROOTDIR = os.getcwd()
'''FPS'''
FPS = 30

3、消消乐所有图形加载

game.py：第一部分

把整个项目放在一整个game.py模块下了，把这个代码文件拆开解读一下。

拼图精灵类：首先通过配置文件中，获取方块精灵的路径，加载到游戏里。

定义move()移动模块的函数，这个移动比较简单。模块之间，只有相邻的可以相互移动。


'''
Function:
    主游戏
'''
import sys
import time
import random
import pygame
 
 
'''拼图精灵类'''
class pacerSprite(pygame.sprite.Sprite):
    def __init__(self, img_path, size, position, downlen, **kwargs):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.image.load(img_path)
        self.image = pygame.transform.smoothscale(self.image, size)
        self.rect = self.image.get_rect()
        self.rect.left, self.rect.top = position
        self.downlen = downlen
        self.target_x = position[0]
        self.target_y = position[1] + downlen
        self.type = img_path.split('/')[-1].split('.')[0]
        self.fixed = False
        self.speed_x = 9
        self.speed_y = 9
        self.direction = 'down'
    def move(self):
                #下移
        if self.direction == 'down':
            self.rect.top = min(self.target_y, self.rect.top+self.speed_y)
            if self.target_y == self.rect.top:
                self.fixed = True
                #上移
        elif self.direction == 'up':
            self.rect.top = max(self.target_y, self.rect.top-self.speed_y)
            if self.target_y == self.rect.top:
                self.fixed = True
                #左移
        elif self.direction == 'left':
            self.rect.left = max(self.target_x, self.rect.left-self.speed_x)
            if self.target_x == self.rect.left:
                self.fixed = True
                #右移
        elif self.direction == 'right':
            self.rect.left = min(self.target_x, self.rect.left+self.speed_x)
            if self.target_x == self.rect.left:
                self.fixed = True
    '''获取当前坐标'''
    def getPosition(self):
        return self.rect.left, self.rect.top
    '''设置星星坐标'''
    def setPosition(self, position):
        self.rect.left, self.rect.top = position

4、随机生成初始布局、相邻消除、自动下落

game.py 第二部分

设置游戏主窗口启动的标题，设置启动游戏的主方法。

包括游戏背景音频、图片和字体设计

res主资源目录

audios：加载游戏背景音乐

fonts：记分牌相关字体

imgs：这里存放的是我们的各种小星星的图形，是关键了的哦。如果这个加载不了，

我们的消消乐就没有任何图形了

6、启动主程序

xxls.py

在主程序中，通过读取配置文件，引入项目资源：包括图片、音频等，并从我们的modules里引入所有我们的模块。
