python飞机大战游戏实例讲解

记得刚学python那会，作过一个飞机大战小项目，这个项目非常经典，可以帮助初学者提高动手能力，今天把它分享出来。

一、项目介绍

先放几张图片

二、项目实现

1.首先安装库

pip install pygame

2.主要python代码

import pygame

from pygame.locals import *
import random
＃https://blog.csdn.net/qq_36079986/article/details/110395731
class HeroPlane(object):# 创建一个飞机的英雄类
 def __init__(self,screen_temp): # 始化方法
 self.x = 200
 self.y = 500
 self.image = pygame.image.load('./img/hero1.png')
 self.screen = screen_temp# 因为在display方法中使用到了screen方法# 但是在类中没有 也不能调用 # 所以说 以传参的方法传递到类中
 self.bullet_list = []
 def display(self):# 创建一个展现飞机的方法
 herp_x1, herp_y1, herp_x2, herp_y2, herp_x3, herp_y3 = -100, -100, -100, -100, -100, -100
 self.screen.blit(self.image,(self.x, self.y))
 for bullet in self.bullet_list:###遍历子弹类对象，赋值给bullet
  herp_x1, herp_y1, herp_x2, herp_y2, herp_x3, herp_y3 = bullet.display()###### bullet对象调用display方法， 显示子弹
  bullet.move()
  if self.bullet_list[0].y < 0:
  del self.bullet_list[0]
 return herp_x1, herp_y1, herp_x2, herp_y2, herp_x3, herp_y3

  # print(len(self.bullet_list),'颗敌方子弹')

  bullet.display()
  if bullet.y > 700:
  del bullet

 self.x = x + 30

def key_control(hero_temp):
 for event in pygame.event.get(): # 判断输入类型

if __name__ == '__main__':
 main()

三、说明：代码功能都在注释里面，我就不做过多解释了；与本项目有关的图片数据我传到资源里面了，大家可以免费下载，我把代码和数据都打包到一起了，大家下载下来导入库就可以直接一些了。

实例补充

import pygame

 def __init__(self,bg_size):
