[pyGame actual combat] aircraft shooting masterpiece: fierce battle in the universe is imminent... This super classic shooting game should also be taken out and restarted~

Introduction

  Hello, hello ！ Good afternoon, ~ I'm kimiko .

Previously, I introduced Python Produced football match 、 skiing 、 Contra 、 Super Mary and dozens of other games , The effect is not bad ,

The response was very enthusiastic . Sure enough, the game still attracts everyone's attention ！

Complete material for all articles + The source code is in

Fans white whoring source code welfare , Please move to CSDN The community or the public at the end of the article hao It's free .

So today we continue to learn to use Python Make a very interesting and scientific game ： Fierce battle in the universe

Space games . Both interesting , And can learn programming , The main thing is that children will definitely like it ~

Gamers will fly a starship , Shuttle through the gorgeous and mottled universe , Facing various tasks and challenges , It can finish

It's this mission ？ We might as well guess, or you can try it yourself ？！ Let's move on to today's theme ！

One 、 Introduction of the principle

First of all, the background of the game , You can see , There are several areas that need to be implemented ：

The first is the background , Because the background of the game is always changing , So it must be a dynamic background ;

The second is music , There is music of bullets , Explosive music of missile hit and impact ;

The third is the spaceship , Including our main ship 、 Enemy spacecraft, etc , There are also big boss Missile attack , Our main ship can launch

Bullets attack enemy ships （ Destroy an enemy plane by three points ）, It can also hit enemy ships , Once our main ship is hit or collided

blow , You will deduct health value once （ Only one debugging can be set here ）, HP reduced to 0, be Game Over！

Two 、 material （ picture 、 Music, etc ）

There are mainly these roles , The spacecraft ( Including our main ship 、 Enemy ships and other different shapes )、 The bullet 、 Missiles and other props ( Different make

type ).

3、 ... and 、 Code display

There are mainly two pieces py The following are posted for everyone

1)main.py The main program
