用python实现简单的飞机大战小游戏

1、下载一个包

PySide2-5.15.2.1-5.15.2-cp35.cp36.cp37.cp38.cp39.cp310-none-win_amd64

如果下载错误，就先下载shiboken2-5.15.2.1-5.15.2-cp35.cp36.cp37.cp38.cp39.cp310-none-win_amd64补丁，然后再下载Pyside2。

记得都放在同一个工程下。

2、准备好飞机大战中所需要的图片资源

（1）自身飞机

（2）飞机子弹

（3）背景

 

（4）敌机

 

将准备好的图片放入工程中的images文件夹中，且命名好

3、代码

我们一共准备六个模块

（1）主函数main模块.py

  19.         if self.y >= self.settings.game_height:
  20.             self.free = True
  21.

4、注意

代码没有问题，在同一工程目录下建6个.py文件然后将代码复制进去就行了

如果有报错，一般就是我上面说的包没有下载或者调用成功，

也可能是图片路径问题。

代码比较少，功能也不是很多，相比于正规游戏这个肯定是没得比的，如果有问题，还望各位大佬多加指点

操作方式：飞机方向由左右两键控制，空格发射子弹，Q退出游戏
