Pygame实战练习之保护单身狗游戏(雪花单身)

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
