导语​

​昨晚玩起了小时候玩的游戏“吃豆豆”，但是我发现，一局游戏三条命，我根本不能吃完所有的豆豆，总是被敌人吃掉

于是，我在想怎么能够保证我达到吃完所有豆豆的目标，然后我就想到了一个办法：

自己找资料找素材学习仿写了一款吃豆豆的小游戏，然后给我自己无限开挂！

哈哈哈！这不？完全解决了我的问题，完美的躺赢了！聪明的我.jpg

一、首先

1）素材

首先找到吃豆豆游戏的界面按照上面的素材找找准备下相似的图片！如下：

2）环境

本文的环境都跟之前的差不多：Python3、Pycharm、Pygame模块。

模块安装：

pip install -i https://pypi.douban.com/simple/ pygame

​二、正式开始

这款吃豆豆的小游戏：主要分为4块主要内容，分别是。Levels.py、Sprites.py、cfg.py、Game.py

1）配置文件：cfg.py

import os '''定义一些颜色'''BLACK = (0, 0, 0)WHITE = (255, 255, 255)BLUE = (0, 0, 255)GREEN = (0, 255, 0)RED = (255, 0, 0)YELLOW = (255, 255, 0)PURPLE = (255, 0, 255)SKYBLUE = (0, 191, 255)'''游戏素材路径'''BGMPATH = os.path.join(os.getcwd(), 'resources/sounds/bg.mp3')ICONPATH = os.path.join(os.getcwd(), 'resources/images/icon.png')FONTPATH = os.path.join(os.getcwd(), 'resources/font/ALGER.TTF')HEROPATH = os.path.join(os.getcwd(), 'resources/images/pacman.png')BlinkyPATH = os.path.join(os.getcwd(), 'resources/images/Blinky.png')ClydePATH = os.path.join(os.getcwd(), 'resources/images/Clyde.png')InkyPATH = os.path.join(os.getcwd(), 'resources/images/Inky.png')PinkyPATH = os.path.join(os.getcwd(), 'resources/images/Pinky.png')

2）定义一些精灵类：Sprites.py

import randomimport pygame  '''墙类'''class Wall(pygame.sprite.Sprite):    def __init__(self, x, y, width, height, color, **kwargs):        pygame.sprite.Sprite.__init__(self)        self.image = pygame.Surface([width, height])        self.image.fill(color)        self.rect = self.image.get_rect()        self.rect.left = x        self.rect.top = y  '''食物类'''class Food(pygame.sprite.Sprite):    def __init__(self, x, y, width, height, color, bg_color, **kwargs):        pygame.sprite.Sprite.__init__(self)        self.image = pygame.Surface([width, height])        self.image.fill(bg_color)        self.image.set_colorkey(bg_color)        pygame.draw.ellipse(self.image, color, [0, 0, width, height])        self.rect = self.image.get_rect()        self.rect.left = x        self.rect.top = y  '''角色类'''class Player(pygame.sprite.Sprite):    def __init__(self, x, y, role_image_path):        pygame.sprite.Sprite.__init__(self)        self.role_name = role_image_path.split('/')[-1].split('.')[0]        self.base_image = pygame.image.load(role_image_path).convert()        self.image = self.base_image.copy()        self.rect = self.image.get_rect()        self.rect.left = x        self.rect.top = y        self.prev_x = x        self.prev_y = y        self.base_speed = [30, 30]        self.speed = [0, 0]        self.is_move = False        self.tracks = []        self.tracks_loc = [0, 0]    '''改变速度方向'''    def changeSpeed(self, direction):        if direction[0] < 0:            self.image = pygame.transform.flip(self.base_image, True, False)        elif direction[0] > 0:            self.image = self.base_image.copy()        elif direction[1] < 0:            self.image = pygame.transform.rotate(self.base_image, 90)        elif direction[1] > 0:            self.image = pygame.transform.rotate(self.base_image, -90)        self.speed = [direction[0] * self.base_speed[0], direction[1] * self.base_speed[1]]        return self.speed    '''更新角色位置'''    def update(self, wall_sprites, gate_sprites):        if not self.is_move:            return False        x_prev = self.rect.left        y_prev = self.rect.top        self.rect.left += self.speed[0]        self.rect.top += self.speed[1]        is_collide = pygame.sprite.spritecollide(self, wall_sprites, False)        if gate_sprites is not None:            if not is_collide:                is_collide = pygame.sprite.spritecollide(self, gate_sprites, False)        if is_collide:            self.rect.left = x_prev            self.rect.top = y_prev            return False        return True    '''生成随机的方向'''    def randomDirection(self):        return random.choice([[-0.5, 0], [0.5, 0], [0, 0.5], [0, -0.5]])

3）定义关卡：Levels.py
