完整源码如下：

主函数代码main.py：

参数设定代码settings.py：

app.ico图片为游戏运行界面左上角图标，随便用那张图片都行，例如直接使用我方飞机图片重命名即可

class Settings:def __init__(self):self.game_title = "python飞机大战"self.game_ico = r"D:\images\app.ico"self.game_width = 512self.game_height = 700self.map_path = r"D:\images\img_bg_level_2.png"self.map_speed = 2self.hero_path = r"D:\images\hero2.png"self.hero_speed = 20self.bullet_path = r"D:\images\bullet_11.png"self.bullet_speed = 10self.bullet_num = 10self.enemy_path = r"D:\images\img-plane_5.png"self.enemy_speed = 3self.enemy_num = 10

敌机代码enemy.py：

from PySide2 import QtGui
from settings import Settingsclass Enemy:def __init__(self):self.settings = Settings()self.img = QtGui.QPixmap(self.settings.enemy_path)self.rect = self.img.rect()self.x = 0self.y = 0self.free = Trueself.speed = self.settings.enemy_speeddef move(self):if self.free:return self.y += self.speedself.rect.moveTo(self.x, self.y)if self.y >= self.settings.game_height:self.free = True

我方飞机代码hero.py：

from PySide2 import QtGui
from settings import Settings
from bullet import Bulletclass Hero:def __init__(self):self.settings = Settings()self.img = QtGui.QPixmap(self.settings.hero_path)self.x = self.settings.game_width*0.5 - self.img.width()*0.5self.y = self.settings.game_height - self.img.height()self.speed = self.settings.hero_speed# 创建一个弹夹，放入10颗子弹self.bullets = []for i in range(self.settings.bullet_num):self.bullets.append(Bullet())def move(self, x, y):'''飞机移动'''self.x = x self.y = ydef shoot(self):'''飞机发射子弹，按空格键时，调用此函数'''for i in range(self.settings.bullet_num):if self.bullets[i].free:self.bullets[i].free = Falseself.bullets[i].x = self.x + self.img.width()*0.5 - self.bullets[i].img.width()*0.5self.bullets[i].y = self.y - 30break

地图代码map.py：

from PySide2 import QtGui
from settings import Settingsclass Map:def __init__(self):self.settings = Settings()self.img1 = QtGui.QPixmap(self.settings.map_path)self.img2 = QtGui.QPixmap(self.settings.map_path)self.y1 = -self.settings.game_heightself.y2 = 0def move(self):self.y1 += self.settings.map_speedif self.y1 >= 0:self.y1 = -self.settings.game_heightself.y2 += self.settings.map_speed   if self.y2 >= self.settings.game_height:self.y2 = 0  

子弹代码bullet.py:

from PySide2 import QtGui
from settings import Settingsclass Bullet:def __init__(self):self.settings = Settings()self.img = QtGui.QPixmap(self.settings.bullet_path)self.rect = self.img.rect()self.speed = self.settings.bullet_speedself.x = 0self.y = 0self.free = Truedef move(self):if self.free:return self.y -= self.speedself.rect.moveTo(self.x, self.y)if self.y <= -self.rect.height():self.free = True

运行方式：运行main.py即可

注意点一：

如果直接用文章中的背景图保存到本地后运行代码，运行结果如下：

 于是自己替换了背景图片，和样例中的背景图调整像素到了一样大小:512x768（游戏界面参数设定是512和700，背景图大小有差别不影响，自己觉得可以就行）：

 替换背景后运行结果如下：

运行结果视频展示（方向键左右移动，空格射击）：

注意点二：

需要安装Pyside2依赖库，直接pip install Pyside2即可，如果出现

qt.qpa.plugin: Could not load the Qt platform plugin "windows" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: minimal, offscreen, windows.错误
