实现步骤
1.创建窗口
2.创建一个玩家飞机，按方向键可以左右移动
3.给玩家飞机添加按空格键发射子弹功能
4.创建一个敌机
5.敌机自动左右移动
6.敌机自动发射子弹
1.创建窗口
import pygame
import time def main():
#1.创建窗口
screen = pygame.display.set_mode((480,852))
#2 创建一个背景图片
background = pygame.image.load('./feiji/background.png') while True:
#3 显示到屏幕
screen.blit(background,(0,0))
pygame.display.update()
time.sleep(0.05) if __name__ == '__main__':
main()
2.显示玩家飞机，检测键盘，控制飞机左右移动
import pygame
import time
from pygame.locals import * class HeroPlane(object):
def __init__(self,screen_temp):
self.x = 210
self.y = 700
self.screen = screen_temp #游戏窗口
self.image = pygame.image.load('feiji/hero1.png') def display(self):
self.screen.blit(self.image,(self.x,self.y)) #加载玩家飞机到窗口 def move_left(self):
self.x -= 5 def move_right(self):
self.x += 5 def key_control(hero_temp):
# 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')
hero_temp.move_left() # 检测按键是否是d或者right
elif event.key == K_d or event.key == K_RIGHT:
print('right')
hero_temp.move_right()
# 检测按键是否是空格键
elif event.key == K_SPACE:
print('space')
def main():
#1.创建窗口
screen = pygame.display.set_mode((480,852),0,0)
#2 创建一个背景图片
background = pygame.image.load('./feiji/background.png')
# 创建一个飞机对象
hero = HeroPlane(screen) while True:
#把背景图片放到窗口显示
screen.blit(background,(0,0))
#显示玩家飞机到定义的（x,y）坐标位置
hero.display()
pygame.display.update()
#检测键盘，控制玩家飞机移动
key_control(hero)
time.sleep(0.05) if __name__ == '__main__':
main()
3.玩家发射子弹
import pygame
import time
from pygame.locals import * class HeroPlane(object):
def __init__(self,screen_temp):
self.x = 210
self.y = 700
self.screen = screen_temp #游戏窗口
self.image = pygame.image.load('feiji/hero1.png')
self.bullet_list = [] #存储发射出去的子弹 def display(self):
# 加载玩家飞机到窗口
self.screen.blit(self.image,(self.x,self.y))
for bullet in self.bullet_list:
bullet.display()
bullet.move() def move_left(self):
self.x -= 5 def move_right(self):
self.x += 5 def fire(self):
self.bullet_list.append(Bullet(self.screen,self.x,self.y)) class Bullet(object):
def __init__(self,screen_temp,x,y):
self.x = x + 40
self.y = y - 20
self.screen = screen_temp
self.image = pygame.image.load('feiji/bullet.png') def display(self):
self.screen.blit(self.image,(self.x,self.y)) def move(self):
self.y -= 20 def key_control(hero_temp):
# 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')
hero_temp.move_left() # 检测按键是否是d或者right
elif event.key == K_d or event.key == K_RIGHT:
print('right')
hero_temp.move_right()
# 检测按键是否是空格键
elif event.key == K_SPACE:
print('space')
hero_temp.fire()
def main():
#1.创建窗口
screen = pygame.display.set_mode((480,852),0,0)
#2 创建一个背景图片
background = pygame.image.load('./feiji/background.png')
# 创建一个飞机对象
hero = HeroPlane(screen) while True:
#把背景图片放到窗口显示
screen.blit(background,(0,0))
#显示玩家飞机到定义的（x,y）坐标位置
hero.display()
pygame.display.update()
#检测键盘，控制玩家飞机移动
key_control(hero)
time.sleep(0.05) if __name__ == '__main__':
main()
效果如下：
4.创建一个敌机
--snip--

--snip--
#4 创建一个敌机

--snip--
enemy.display()
--snip
5.控制敌机左右移动

--snip--
self.direction = 'right' #定义敌机默认往右移动
--snip-- def move(self):

self.direction = 'left'
elif self.x < 0:
self.direction = 'right'
--snip-- def main():
--snip--
#4 创建一个敌机

--snip--
bullet.move()
if bullet.judge(): #判断子弹是否越界
self.bullet_list.remove(bullet)
--snip-- class Bullet(object):

return True
