如何利用python来制作保护单身狗游戏

本篇文章为大家展示了如何利用python来制作保护单身狗游戏，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

首先准备好图片素材等：

bgm音乐必备：

import pygame class Sound():    def __init__(self):        pygame.mixer.music.load('../sound/baab.mp3')        pygame.mixer.music.play()

先上效果图嘿嘿嘿 看好哈：

游戏界面--

程序运行--

（1）设置滚动的背景：

#地图滚动import pygameimport random class GameBackground(object):    # 初始化地图    def __init__(self, scene):        # 加载相同张图片资源,做交替实现地图滚动        self.image1 = pygame.image.load("../image/background.png")        self.image2 = pygame.image.load("../image/background.png")        # 保存场景对象        self.main_scene = scene        # 辅助移动地图        self.x1 = 0        self.x2 = 1280        self.snowflag=False     # 计算地图图片绘制坐标    def action(self):        self.x1 = self.x1 - 1        self.x2 = self.x2 - 1        if self.x1 <= -1279:            self.x1 = 1279        if self.x2 <= -1279:            self.x2 = 1279     # 绘制地图的两张图片    def draw(self):        self.main_scene.blit(self.image1, (self.x1,0))        self.main_scene.blit(self.image2, (self.x2,0))  class Snow():                # 雪花的竖直速度    def __init__(self):        self.x = 0  # 雪花的横坐标        self.y = 0  # 雪花的纵坐标        self.vx = 0  # 雪花的水平速度        self.vy = 0        self.x = random.randint(0,1280)   # 初始化雪花横坐标        self.y = random.randint(0,390)   #初始化雪花纵坐标    def getsnowpos(self):        return self.x,self.y         # 返回雪花坐标位置

（2）单身狗不能碰到情侣检测碰撞：

import pygame  class Collide():    def __init__(self):        self.gamestatus=True        self.snowflag=False        self.dogflag=0        self.score=0        self.scoreup=200        self.gameover=False        self.count=0     def dogs_cpdogs(self,dogs,cpdogs):        boooooooooooooooool=pygame.sprite.groupcollide(dogs,cpdogs,False,True)        if boooooooooooooooool:            self.score += self.scoreup            print(self.score)     def dog_cpdog(self,dog,cpdog2s):        booooooool=pygame.sprite.spritecollide(dog,cpdog2s,True)        if booooooool:            self.snowflag = True            self.count += 1            if self.count>=3:                self.gameover=True

（3）主函数：
