根据资料学习，代码是在资料的基础上，重新打的，有部分修改。

他写了一个打飞机游戏，我决心把这个整个自己写一遍，并且自己做些图像和代码，甚至玩法的修改

第1部分，写了地图和飞机

# -*- coding:utf-8 -*-

import pygame
from pygame.locals import *
import sys
import math

screen_width=600
screen_hight=800

pygame.init()

screen=pygame.display.set_mode((screen_width,screen_hight))
caption=pygame.display.set_caption("plane battle")

background=pygame.image.load("temp\\map001.jpg")
plane=pygame.image.load("temp\\plane001.jpg")

while True:
	
	screen.blit(background,(0,0))
	screen.blit(plane,(300,400))
	
	for event in pygame.event.get():
		if event.type==QUIT:
			sys.exit()

	pygame.display.update()

 第2部分，设计可看起来动的飞机

注意问题

（1）subsurface 是取图片中的一块区域

       subsurface([左下角pos],[width,heigth])

        坐标系注意是常规的数学坐标系x 右，Y 上， 左下角00
（2）pyfame的坐标轴是 x 右，Y 下

（3）比如使用notepad++时，注意使用 视图--显示符号--显示换行符号和空格等

      可以查错，比如

（备注：）暂时问题是，time的导入好像有问题，先注了

# -*- coding:utf-8 -*-

hero1_rect = pygame.Rect(0,0,156,138)
hero2_rect = pygame.Rect(156,0,156,138)
hero1 = plane_img.subsurface(hero1_rect)
hero2 = plane_img.subsurface(hero2_rect)
hero_pos = [222, 650]
 
#clock=pygame.time.clock()

 
 
while True:
	#clock.tick(60)

				offset[event.key] = 3
		elif event.type == pygame.KEYUP:
			if event.key in offset:
				offset[event.key] = 0

		# part 1
		#offset_x = offset[pygame.K_RIGHT] - offset[pygame.K_LEFT]
		#offset_y = offset[pygame.K_DOWN] - offset[pygame.K_UP]
		#hero_pos = [hero_pos[0] + offset_x, hero_pos[1] + offset_y]
	# part 2
	offset_x = offset[pygame.K_RIGHT] - offset[pygame.K_LEFT]
	offset_y = offset[pygame.K_DOWN] - offset[pygame.K_UP]
	hero_pos = [hero_pos[0] + offset_x, hero_pos[1] + offset_y]

	elif hero_x > screen_width - hero1_rect.width:
		hero_pos[0] = screen_width - hero1_rect.width
	else:
		hero_pos[0] = hero_x

	if hero_y < 0:
		hero_pos[1] = 0
	elif hero_y > screen_hight - hero1_rect.height:
		hero_pos[1] = screen_hight - hero1_rect.height
	else:
		hero_pos[1] = hero_y

 第4步：尝试修改为发射2个子弹

遇到很多问题

（1） 本来想用1个子弹类，好像没搞定

（2）2个类看起来很费

（3）遇到很多问题

用rect搞2个子弹，4个参数，加各种topleft完全不懂

这里卡了很久

各种  rect方法  surface方法，都不太懂，坐标系等

（4） 图片好像PNG的更好？

（5）注意缩进 要么全空格 要么全TAB
