只是简单的学习了pygame，实现飞机的摧毁还需要多张图片的切换，和sprite（碰撞精灵），还有多种音效的添加（如背景音乐、摧毁特效）。以后再深入学习我只是练习一下python。
一、搭建界面（基于pygame的）
#coding=utf-8
import pygame '''
1. 搭建界面，主要完成窗口和背景图的显示
''' if __name__ == "__main__": #1. 创建一个窗口，用来显示内容
screen = pygame.display.set_mode((480,890),0,32) #2. 创建一个和窗口大小的图片，用来充当背景
background = pygame.image.load("./feiji/background.png").convert() #3. 把背景图片放到窗口中显示
while True:
screen.blit(background,(0,0))
pygame.display.update()
二、检测键盘
#coding=utf-8
import pygame
from pygame.locals import * '''
2. 用来检测事件，比如按键操作
''' if __name__ == "__main__": #1. 创建一个窗口，用来显示内容
screen = pygame.display.set_mode((480,890),0,32) #2. 创建一个和窗口大小的图片，用来充当背景
background = pygame.image.load("./feiji/background.png").convert() #3. 把背景图片放到窗口中显示
while True: #设定需要显示的背景图
screen.blit(background,(0,0)) #获取事件，比如按键等
for event in pygame.event.get(): #判断是否是点击了退出按钮
if event.type == QUIT:
print("exit")
exit()
#判断是否是按下了键
elif event.type == KEYDOWN:
#检测按键是否是a或者left
if event.key == K_a or event.key == K_LEFT:
print('left') #检测按键是否是d或者right
elif event.key == K_d or event.key == K_RIGHT:
print('right') #检测按键是否是空格键
elif event.key == K_SPACE:
print('space') #更新需要显示的内容
pygame.display.update()
三、显示、控制玩家飞机并发射子弹
#coding=utf-8
import pygame
from pygame.locals import * ''' 1. 实现飞机在你想要的位置显示
2. 实现按键控制飞机移动
3. 实现按下空格键的时候，显示一颗子弹
''' class HeroPlane(object): def __init__(self,screen): #设置飞机默认的位置
self.x = 230
self.y = 600 #设置要显示内容的窗口
self.screen = screen self.imageName = "./feiji/hero.gif"
self.image = pygame.image.load(self.imageName).convert() #用来存储英雄飞机发射的所有子弹
self.bulletList = [] def display(self):
self.screen.blit(self.image,(self.x,self.y)) for bullet in self.bulletList:
bullet.display()
bullet.move() #修改所有子弹的位置
# for bullet in self.bulletList:
# bullet.y -= 2 def moveLeft(self):
self.x -= 10 def moveRight(self):
self.x += 10 def sheBullet(self):
newBullet = Bullet(self.x,self.y,self.screen)
self.bulletList.append(newBullet) class Bullet(object):
def __init__(self,x,y,screen):
self.x = x+40
self.y = y-20
self.screen = screen
self.image = pygame.image.load("./feiji/bullet-3.gif").convert() def move(self):
self.y -= 2 def display(self):
self.screen.blit(self.image,(self.x,self.y)) if __name__ == "__main__": #1. 创建一个窗口，用来显示内容
screen = pygame.display.set_mode((480,890),0,32) #2. 创建一个和窗口大小的图片，用来充当背景
background = pygame.image.load("./feiji/background.png").convert() #3. 创建一个飞机对象
heroPlane = HeroPlane(screen) #3. 把背景图片放到窗口中显示
while True:
screen.blit(background,(0,0)) heroPlane.display() #判断是否是点击了退出按钮
for event in pygame.event.get():
# print(event.type)
if event.type == QUIT:
print("exit")
exit()
elif event.type == KEYDOWN:
if event.key == K_a or event.key == K_LEFT:
print('left')
heroPlane.moveLeft()
#控制飞机让其向左移动
elif event.key == K_d or event.key == K_RIGHT:
print('right')
heroPlane.moveRight()
elif event.key == K_SPACE:
print("space")
heroPlane.sheBullet() pygame.display.update()
四、显示、控制敌人飞机并发射子弹
#coding=utf-8
import time
import random
import pygame
from pygame.locals import * class HeroPlane(object): def __init__(self,screen): #设置飞机默认的位置
self.x = 230

self.screen = screen self.imageName = "./feiji/hero.gif"
self.image = pygame.image.load(self.imageName).convert() #用来存储英雄飞机发射的所有子弹
self.bulletList = [] def display(self):
#更新飞机的位置
self.screen.blit(self.image,(self.x,self.y)) #判断一下子弹的位置是否越界，如果是，那么就要删除这颗子弹
#
#这种方法会漏掉很多需要删除的数据
# for i in self.bulletList:
# if i.y<0:
# self.bulletList.remove(i) #存放需要删除的对象信息
needDelItemList = [] for i in self.bulletList:
if i.judge():
needDelItemList.append(i) for i in needDelItemList:
self.bulletList.remove(i) # del needDelItemList #更新及这架飞机发射出的所有子弹的位置
for bullet in self.bulletList:
bullet.display()
bullet.move() #修改所有子弹的位置
# for bullet in self.bulletList:

self.screen.blit(self.image,(self.x,self.y)) def judge(self):
if self.y<0:
return True
else:
return False class EnemyPlane(object): def __init__(self,screen): #设置飞机默认的位置
self.x = 0
self.y = 0 #设置要显示内容的窗口
self.screen = screen self.imageName = "./feiji/enemy-1.gif"
self.image = pygame.image.load(self.imageName).convert() #用来存储敌人飞机发射的所有子弹
self.bulletList = [] self.direction = "right" def display(self):

for bullet in self.bulletList:
bullet.display()
bullet.move() def move(self): #如果碰到了右边的边界，那么就往左走，如果碰到了左边的边界，那么就往右走
if self.direction == "right":
self.x += 2
elif self.direction == "left":
self.x -= 2 if self.x>480-50:
self.direction = "left"
elif self.x<0:
self.direction = "right" def sheBullet(self):
num = random.randint(1,100)
if num == 88:
newBullet = EnemyBullet(self.x,self.y,self.screen)
self.bulletList.append(newBullet) class EnemyBullet(object):
def __init__(self,x,y,screen):
self.x = x+30

return True
else:

while True:

for event in pygame.event.get():
# print(event.type)
if event.type == QUIT:
print("exit")
exit()
elif event.type == KEYDOWN:
if event.key == K_a or event.key == K_LEFT:
print('left')
heroPlane.moveLeft()
#控制飞机让其向左移动
elif event.key == K_d or event.key == K_RIGHT:
print('right')
heroPlane.moveRight()
elif event.key == K_SPACE:
print("space")
heroPlane.sheBullet() #通过延时的方式，来降低这个while循环的循环速度，从而降低了cpu占用率
time.sleep(0.01) pygame.display.update()
