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 pygame
import 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：
