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

正文

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 random
import pygame


'''墙类'''
class Wall(pygame.sprite.Sprite):
    def __init__(self, x, y, width, height, color, **kwargs):
        pygame.sprite.Sprite.__init__(self)

        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):

        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)

                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
