【Pygame系列】别样的飞机大战：太空陨石VS大型战机对决（内含源码）-编程知识网

12月的心境：一半优，一半喜。

12月的天空：一半晴，一半雨。

12月的风：已不再那么的轻柔，带有无言的烦躁！甚至裹着疼痛的雨。

2022年的尾巴：已悄悄来临！

临近新的一年，小编为大家准备了一套系列《从简易到豪华版——3个版的“飞机大战”小游戏》

大家可以先自行💭想象~嘿嘿。等我慢慢更新这个系列，今天先给大家更新一个基础版本的飞机大

战吧！

其实说是基础的话也不是很基础：界面特别精致、然后还有相应的防护盾等功能，只是因为第一款

的飞机大战是天上掉下陨石然后敌机的话没得，等我给大家下次升级在给大家写哈！

那么——我们就正式开始干活儿吧👇👇👇👇👇👇

【Pygame系列】别样的飞机大战：太空陨石VS大型战机对决（内含源码）-编程知识网

正文

故事背景：（纯虚构，勿认真）

12月30号晚上凌晨，🌏发生陨石坠落。现场视频显示，当晚夜空忽然被照亮，一道红光从空中划

过，几秒后迅速消失。经过研究，预计今天还会有新一波的大量陨石从天而降，甚至这大量陨石的

降落威胁到了人们的生活，造成了多起医疗事故，所以最后出动了保卫战战队进行宇宙的陨石消灭

计划！我们要尽可能的击碎甚至消灭这些大量的陨石………..计划开始……..

一、游戏规则

我们设计了一款基于Python的Pygame模块开发的飞机大战游戏。

飞机大战游戏是一款休闲益智类游戏，既简单又耐玩。在初始界面，我们有开始游戏和退出游戏两

个选项。

开始游戏后，玩家可以用上下左右方向键的控制飞机在屏幕上向任意方向移动，通过空格键射击陨

石得分，有护盾加生命以及闪电⚡加攻击炮弹，初始化生命为3次在屏幕右上角可以看到当前生

命，中间可以看得分。

二、准备中

1)素材图片

2）来点儿Music

三、代码演示
