第1章节 新式类及保护对象的属性
新式类的样式（括号中有object）：
# 1、导入模块（先pip3 install pygame）
import pygame
# 4、导入按键的检测
from pygame.locals import *
# 6、导入时间库，控制程序运行速度
import time
# 7、创建飞机类
class PlayerPlane(object):
def __init__(self):
# 子弹列表
self.bulletList = []
planeImageName = "/home/li/Documents/image/hero1.png"
self.image = pygame.image.load(planeImageName).convert_alpha()
planeImageName1 = "/home/li/Documents/image/hero2.png"
self.image1 = pygame.image.load(planeImageName1).convert_alpha()
# 初始位置
self.x = 230
self.y = 600
# 设置速度
self.speed = 5
# 设置名字
self.planeName = "player"
def draw(self, screen):
screen.blit(self.image, (self.x, self.y))
# screen.blit(self.image1, (self.x, self.y))
# 2、打开一个窗口，加载背景
if __name__ == '__main__':
screen = pygame.display.set_mode((480, 852), 0, 32)
bgImamgeFile = './image/background.png'
background = pygame.image.load(bgImamgeFile).convert()
pp1 = PlayerPlane()
# 3、背景贴到screen上，然后刷新窗口。while True非常耗资源。
while True:
screen.blit(background, (0, 0))
pp1.draw(screen)
# 5、按键的检测。固定代码块。先执行blit，再看这里有没有按键，有就执行，没有就刷新，再循环一次。
for event in pygame.event.get():
if event.type == QUIT:
print("exit")
exit()
elif event.type == KEYDOWN:
if event.key == K_a or event.key == K_LEFT:
pp1.x -= 10
print("left")
elif event.key == K_d or event.key == K_RIGHT:
pp1.x += 10
print("right")
elif event.key == K_w or event.key == K_UP:
pp1.y -= 10
print("up")
elif event.key == K_s or event.key == K_DOWN:
pp1.y += 10
print("down")
elif event.key == K_SPACE:
print("space")
pygame.display.update()
# 6.1 1秒会很卡。比较好的是0.01
time.sleep(0.01)
相对完整的版本
# 1、导入模块（先pip3 install pygame）

# 4、导入按键的检测

# 6、导入时间库，控制程序运行速度

# 7、创建飞机类

# 8、创建子弹类
# 8.1单颗子弹，如何把他画出来？考虑飞机的画法。飞因为只有一个，所以实例化一个飞机，直接在循环中pp1.draw。
# 8.1那么也定义一个子弹集合类，这个集合类有个方法，draw所有子弹，是否可行？
