Python Basics: Simply write a star war in Python, but it can't be used to fish~

Through the recent observation of spicy strips, everyone seems to have a soft spot for paddling and fishing. So I went back to my old business and wrote such a simple version of the Star Wars mini-game.

Of course, the original intention of spicy strips is definitely not to let you paddle the water and fish for fish. I really want you to learn a little bit from it. All in all, I hope everyone will stop stepping on the road of Python, because someone was talking to the seniors yesterday. , in the future, you will get a high salary like adding, deleting, modifying and checking. I don’t believe that it has fallen like this now.

Just like asking sensible brothers and sisters, do you think it is possible?

1. Game screen

2. Game over screen

3. Game material

4. Game code

星空飞碟大战.py
由于配音需要混音器,这里用到了pygame的混音器,

1. Import the module

from sprites import *
import pygame.mixer

2. Dynamic star background function

def star_move():
  """动态星空背景函数"""
  for star in stars:
    star.move(0,-20)
    if star.ycor() < -height//2:
      x = random.randint(-width//2,width//2)
      y = random.randint(10+height//2,height*2)
      star.reborn(x,y,0,-20)

3. Generate enemy aircraft functions from time to time

def spawn_enemy():
  """不定时产生敌机函数"""
  if random.randint(1,10)==1 and len(enemys)<10:
    x = random.randint(-200,200)
    y = random.randint(100,300)
    enemy = Sprite(shape='res/ufo.png',visible=False,pos=(x,y),tag='enemy')
    enemy._rotatemode = 1
    enemy.scale(0.5)
    enemy.setheading(random.randint(1,360))
    enemy.show()

4. The movement of the flying saucer

def enemymove():
  """飞碟的移动"""  
  for e in enemys:
    e.fd(3)    
    # 设定一定的机率让ufo朝向player
    if random.randint(10,100) == 10 and \
       abs(e.xcor())<200 and abs(e.ycor()<250):
      e.heading(player)
    
    e.bounce_on_edge()

5. Bullet movement

def bulletmove():
  """子弹的移动"""  
  for b in list(bullets):
     b.move(0,10)
     if b.collide_edge():b.remove()

6. Player shooting function

def player_shoot():
  """玩家射击函数"""
  if player.alive == False : return 
  if m1.down() and framecounter % 5 == 0 :
     b = Sprite(shape='circle',visible=False,tag='bullet')
     b.scale(0.5)
     b.color('yellow')    
     b.goto(player.pos())        # 移到player坐标
     b.show()                    # 显示子弹
     shoot.play()                # 播放射击声

7. Play background music and generate sound effect objects

# 播放背景音乐与生成声效对象
pygame.mixer.init()
pygame.mixer.music.load('audio/FrozenJam.ogg')
pygame.mixer.music.play(-1,0)
explosion = pygame.mixer.Sound('audio/expl3.wav')
shoot = pygame.mixer.Sound('audio/pew.wav')

8. New screen

width,height = 480,640
screen = Screen()               # 新建屏幕
screen.bgcolor('black')         # 屏幕背景色为黑
screen.setup(width,height)
screen.title("星空飞碟大战by大海老师")
screen.addshape('res/fighter.png')
screen.addshape('res/ufo.png')
frames = ['res/explosion0.png','res/explosion1.png']
[screen.addshape(frame) for frame in frames]

9. Move the stamp to realize the stars

# 星星，用来做向下滚动背景,星星的移动也可以通过移动图章实现
# 这样可以有更多的星星。如果用克隆的话有数量限制,根据计算机配置不同而不同。
star = Sprite(shape='circle')
star.color('white')
star.scale(0.1)
stars = [star]
stars.extend([star.clone() for _ in range(20)])
for star in stars:
  x = random.randint(-width//2,width//2)
  y = random.randint(10+height//2,height*2)
  star.goto(x,y)

10. Crying face

cry = Sprite(shape='cry.png',visible=False,pos=(0,100))

11. Players

player = Sprite(shape='res/fighter.png',pos=(0,-200))
player.scale(0.65)
player.alive = True             # 表示player是活的

m1 = Mouse()                    # 鼠标左键检测实例
clock = Clock()                 # 实钟对象,用来控制fps
framecounter = 0
counter = 0                     # 统计击中的ufo数量
bullets = Group('bullet')       # 子弹组
enemys = Group('enemy')         # ufo敌人组

12. Flying saucer movement and bullet movement

while counter<100:
  framecounter += 1             # 帧计数器
  spawn_enemy()                 # 不定时产生敌机UFO
  player_shoot()                # 单击鼠标左键,射击子弹
  enemymove()                   # 飞碟们的移动 
  bulletmove()                  # 子弹的移动
  if player.alive:
    player.goto(mousepos())
  else:
    cry.show()                  # 显示哭脸,表示失败
  star_move()                   # 星空滚动背景    

13. Collision detection of enemy aircraft

for e in list(enemys):        # 对每架敌机进行碰撞检测
  if e.collide(player,scale=0.6):            
      explode(e.position(),frames)
      e.remove()
      explode(player.pos(),frames)
      player.remove()
      player.alive = False
      explosion.play()         # 爆炸声
      break
  # 敌机是否碰到任意一颗子弹
  for b in list(bullets):
    if b.collide(e,scale=0.6): # 如果子弹碰到UFO        
      explode(e.position(),frames)
      e.remove()
      b.remove()
      explosion.play()         # 爆炸声
      counter +=1              # 进行统计         
      break            

screen.title('星空飞碟大战,当前击毙：' +  str(counter) + " 架UFO")  
clock.tick(60)

14. The bullet is successfully deleted after breaking through the level

[b.remove() for b in list(bullets)] # 闯关成功把子弹删除
for e in list(enemys):              # 每架飞碟都爆炸
  explode(e.position(),frames)
  e.remove()  
  clock.tick(10)
    
t = Turtle(visible=False)
t.color('yellow')
t.write('成功闯关!',align='center',font=('黑体',32,'normal'))

while True:
  player.goto(mousepos()) 
  star_move()                   # 星空滚动背景  
  clock.tick(60)

t = Turtle(visible=False)
t.color('yellow')
t.write('Successful clearance!',align='center',font=('black body',32,'normal'))

while True:
player.goto(mousepos())
star_move() # starry sky rolling background
clock.tick(60)

Five: Summary

There is no doubt that everyone here is a proper iron fan. Since they are iron fans, I will give you a chance to get in touch. Below is my personal ming film . I found me, but there are a lot of source codes, learning routes and so on. I won't reveal it, it depends on everyone's own enthusiasm~
Secondly, I reiterate again that I really don't want you to touch the fish, although it is a very simple thing, but for beginners, or younger brothers and sisters who have no solid foundation It is estimated that it is difficult for us to achieve it, so in the end, everyone cheers~
