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

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

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。
