Pygame实战练习之保护单身狗游戏

导语

各位戏精大家好！我是木木子，这个中秋已经结束了，你们都带着对象回家了码？

中秋那几天朋友圈简直是大型秀恩爱现场。

又是一年中秋夜，依旧凭实力单身！呼吁大家记得保护下单身狗啊喂！

​

作为一条人畜无害可可爱爱的单身狗

每年的假期几乎都被伤的体无完肤，今年我们不仅要好好生存，还要勇敢报复,让情侣们知道:

单身狗不是这么好欺负的~单身狗们报仇吧！今天带大家写一款贼有趣的单身狗小游戏~

​

正文

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
