      python实现飞机大战游戏

       更新时间2019年04月24日 11:07:21   作者寸草&春晖   我要评论

      这篇文章主要为大家详细介绍了python实现飞机大战游戏具有一定的参考价值感兴趣的小伙伴们可以参?#23478;?#19979;

      飞机大战Python代码分为两个python文件工具类和主类需要安装pygame模块能完美运行网上好多不完整的调试得心累实现出来成就感还是满满的如图所示

      完整代码如下

      1.工具类plane_sprites.py

      import random
      import pygame
      
      # 屏幕大小的常量
      SCREEN_RECT = pygame.Rect(0, 0, 480, 700)
      # 刷新的帧率
      FRAME_PER_SEC = 60
      # 创建敌机的定时器常量
      CREATE_ENEMY_EVENT = pygame.USEREVENT
      # 英雄发射子弹事件
      HERO_FIRE_EVENT = pygame.USEREVENT + 1
      
      class GameSprite(pygame.sprite.Sprite):
        """飞机大战游戏精灵"""
        def __init__(self, image_name, speed=1):
          super().__init__()# 调用父类的初始化方法
          self.image = pygame.image.load(image_name)# 定义对象的属性
          self.rect = self.image.get_rect()
          self.speed = speed
        def update(self):
          # 在屏幕的垂直方向上移动
          self.rect.y += self.speed
      class Background(GameSprite):
        """游戏背景精灵"""
        def __init__(self, is_alt=False):
          super().__init__("C:/Users/Administrator/Desktop/background.png")# 1. 调用父类方法实现精灵的创建(image/rect/speed)
          if is_alt:# 2. 判断是否是交替图像如果是需要设置初始位置
            self.rect.y = -self.rect.height
        def update(self):
          super().update()# 1. 调用父类的方法实现
          if self.rect.y >= SCREEN_RECT.height:# 2. 判断是否移出屏幕如果移出屏幕将图像设置到屏幕的?#25103;?
            self.rect.y = -self.rect.height
      class Enemy(GameSprite):
         """敌机精灵"""
         def __init__(self):
           super().__init__("C:/Users/Administrator/Desktop/enemy1.png")# 1. 调用父类方法创建敌机精灵同时指定敌机?#35745;?
           self.speed = random.randint(1, 3)# 2. 指定敌机的初始随机速度 1 ~ 3
           self.rect.bottom = 0# 3. 指定敌机的初始随机位置
           max_x = SCREEN_RECT.width - self.rect.width
           self.rect.x = random.randint(0, max_x)
         def update(self):
           super().update()# 1. 调用父类方法保持垂直方向的飞行
           # 2. 判断是否飞出屏幕如果是需要从精灵组删除敌机
           if self.rect.y >= SCREEN_RECT.height:
             self.kill()
             # print("飞出屏幕需要从精灵组删除...")
             # kill方法可以将精灵从所有精灵组中移出精灵就会被自动销毁
      
         def __del__(self):
             # print("敌机挂了 %s" % self.rect)
             pass
      class Hero(GameSprite):
        """英雄精灵"""
        def __init__(self):
          super().__init__("C:/Users/Administrator/Desktop/me1.png", 0)
          self.rect.centerx = SCREEN_RECT.centerx
          self.rect.bottom = SCREEN_RECT.bottom - 120
          self.bullets = pygame.sprite.Group()
        def update(self):
          self.rect.x += self.speed
          if self.rect.x < 0:
            self.rect.x = 0
          elif self.rect.right > SCREEN_RECT.right:
            self.rect.right = SCREEN_RECT.right
        def fire(self):
          print("发射子弹...")
          for i in (0, 1, 2):
            bullet = Bullet()
            bullet.rect.bottom = self.rect.y - i * 20
            bullet.rect.centerx = self.rect.centerx
            self.bullets.add(bullet)
      class Bullet(GameSprite):
        """子弹精灵"""
        def __init__(self):
          super().__init__("C:/Users/Administrator/Desktop/bullet1.png", -2)
        def update(self):
          super().update()
          if self.rect.bottom < 0:
            self.kill()
          def __del__(self):
            print("子弹被销毁...")
      

      2.主类plane_main.py

      import pygame
      from plane_sprites import *
      class PlaneGame(object):
        """飞机大战主游戏"""
        def __init__(self):

           self.__create_sprites()
           pygame.time.set_timer(CREATE_ENEMY_EVENT, 1000)
           pygame.time.set_timer(HERO_FIRE_EVENT, 500)
        def __create_sprites(self):
          bg1 = Background()
          bg2 = Background(True)
          self.back_group = pygame.sprite.Group(bg1, bg2)
          self.enemy_group = pygame.sprite.Group()
          self.hero = Hero()
          self.hero_group = pygame.sprite.Group(self.hero)
        def start_game(self):
