pygame-飞机大战(上)
前言：当时(去年三月)接下来这个项目的时候，由于各种关系还没有开始着手，七月在天津实训的时候学了会儿(以后也许会发出来吧，不过都是半成品)，之后就准备考研。这个项目还是得做的，本来就打算这个寒假完成，其实考研期间还挺犹豫，因为还不知道做什么游戏，前几天开了个会商榷了一下，ycb(YYyyCCCcccBb )说他五六月份已经把飞机大战的雏形搭建好了，本来我的本意是想做主剧情类的，但是他都搭建好了也只能用雏形做咯。（刚开始以为是他从哪里download下来的，后来发现他有好多拼写错误以为他自己写的，后来才知道他从书上抄下来的），最近差不多花了五六天(的晚上)对他给的雏形进行理解(连个注释都没有)和深度优化(那个雏形的效果简直不能看)，然后增加了点功能。我是负责第一关的，所以以后还会再改进(再更)。
总体效果：
先说下不足（以后有时间会完成）：1.暂时没找到合适的各种背景图和logo 以及本机的贴图
2.除了清屏道具以外其他道具使用的实现
3.金币商城内武器系统未上线
4.死亡、下一关特效及提示等
5.显示文档只能第一页(懒得写翻页了)
实现(优化)了的内容:1.菜单各按钮的功能 2.金币商城内购买的提升属性的提升 3.敌机、石头、bonus的随机性 4.部分彩蛋和道具
在这里介绍一下写的部分函数：
Display.py:(没有写完，只能显示前十行)
import pygame.font
from Codes.Common.DrawBase import DrawOn,_DrawCallInstance
from Codes.Base.Screen import _ScreenInstance
from Codes.Logic.GameStats import _GameStatsInstance
class Display(DrawOn):
def __init__(self,text):
super().__init__()
super(Display,self).definePriority(9)
self.screen=_ScreenInstance.screen
self.screen_rect=(0,0,1200,800)
self.bg_color=(255,255,255)
self.text_color=(0,0,0)
pygame.font.init()
self.font_format=pygame.font.SysFont('SimHei',20)
self.total=10 #一页显示最多个数
self.length=len(text)
self.text=text
self.width, self.height=200,111
self.image=pygame.image.load(r'D:/MyG/icons/back.png')
self.image=pygame.transform.scale(self.image,(self.width,self.height))
self.image_rect=(0,0)
self.rect=pygame.Rect(0,0,self.width, self.height)
def pre_draw(self):
_DrawCallInstance.add(self)
def draw(self):
i=0
k=0
self.screen.fill(self.bg_color, self.screen_rect)
self.screen.blit(self.image,(0,0,200,111))
while k实例化这个类的时候需要输入一个txt(字符串数组,数组中每个值代表一行),show/pre_show/draw函数在很多类中都有，每次循环update的时候都会调用各个show，show调用pre_show（感觉直接就把preshow的代码写在show里也可以），把这个类的实例化对象放入一个类似于队列的drawcall，drawcall对队列中所有对象进行优先级排序(Priority),优先级大的对象会先调用自身的draw在屏幕上绘制。
self.rect是定义的点击事件触发的范围,check函数就是对应的触发事件，在这里image为back，就是显示文本后的返回键，点击返回键(self.rect的范围)，就会触发check函数 (这个在UImgr.py里)，更改对应的几个状态值。
GameStats包含了几个状态值：
from Codes.Base.GameSettings import _GameSettingsInstance
class GameStats():
def __init__(self ):
pass
def init(self):
self.reset_stats()
self.game_active=False
self.display_active=False
self.rank_active=False
self.help_active=False
self.store_active=False
def reset_stats(self):
self.ships_left = _GameSettingsInstance.ship_limit#left=剩下的生命
def printstats(self):
print('game'+str(self.game_active))
print('display'+str(self.display_active))
print('rank'+str(self.rank_active))
print('help'+str(self.help_active))
print('store'+str(self.store_active))
_GameStatsInstance= GameStats()
在UImgr里会根据当前不同的状态值处理不同的点击事件和调用对应的show，且最多同时只有一个状态为True：
| 状态名 | 为True时的含义 |
| game_active | 显示对战界面 |
| display_active | 显示日志(log) |
| rank_active | 显示排名(rank) |
| help_active | 显示帮助(help) |
| store_active | 显示金币商城界面 |
| 都为False | 显示菜单 |

_UIMgrInstance=UIMgr()初始化时，分别对开始、退出、排名等类进行实例化，每次update时，检查状态情况，如果都为false，则调用五个(logo.begin.quit.rank.help)的show,实现显示菜单，如果display/rank/help为active的时候，则调用对象里的displayUI(已实例化Display类)的显示，实现显示不同的三个文本，如果store为True，则显示金币商店；check_Mouse在Handle.py被调用：每次收到鼠标点击时，执行check_Mouse:根据不同的当前状态执行对应的check
Handle.py和Event.py:
import sys
import pygame
from Codes.Common.Event import _EventPatcher
from Codes.UI.UIMgr import _UIMgrInstance
class Handle():
def init(self):
self.add(pygame.K_q, self.exit)

if type not in self.map2ListDistributeEvnet :
print('按键未注册')
return
for event in self.map2ListDistributeEvnet[type]:
event()
_EventPatcher =Event()
Handle的update根据不同的键盘/鼠标输入处理进行不同的dispatch,Event.py定义个一个事件分发器类(ycb,飞机大战总结)。

其中logo用几个jpg实现了gif的效果：每次show时，查看当前时间 如果是0.25 则显示第一张，以此类推，点击三次logo会显示log.txt（算是彩蛋），大部分的check通过更改Gamestats的状态值即可实现界面的切换。其中logo/rank/help先读取对应的文件，再生成display对象，在UImgr中被调用对象的show。
比较特殊的，商店系统中的内容丰富一些：

在handleinit函数里，将按键类型和操作联系到一起，并执行handle类的add添加事件。在ship类里同时对不同的操作进行了声明：wasd移动，空格射击(Batlle类的hit)，p进入商店，o退出商店回到游戏，按p进入商店时，由于道具类只出现一种，在这里产生随机数，同时vip和pac(永久加成卡)只出现一次（购买之后就不会在出现），所以针对不同的情况对随机数做了一定的偏移。

Init:初始化 并重置主机的位置
Sethost：将（ship）设置为主要操作对象
Hit：[按下空格触发] 发射子弹：如果[按下空格后]当前子弹个数小于最大允许发射子弹个数，创建子弹放入
Update 刷新（一直会执行）：不断执行子弹参数的更新和敌机(alien)和陨石/bonus[合并写入alien的不分函数 例如 update_aliens]
check_Bullet：检查所有子弹 如果到达屏幕上端 则自杀[kill](注释区的remove也可以)
Create_XXX:生成一个XXX
update_aliens：先调用check_fleet_edges（见下一个） 执行alien和陨石和bonus的update函数[在Alien等定义]，检查本机和陨石、本机和石头是否碰撞[spritecollideany(A,B,bool) ,单精灵A和多个B进行检查碰撞 bool为False（默认） 则B碰撞后保留 为True则碰撞的经历删除]，并对到达底部的alien/stone/bonus删除
check_fleet_edges：如果单个石头/敌机到达左右边缘 则自杀 如果bonus到达左右边缘 则反弹
check_aliens_bottom：如果单个石头/敌机/bonus到达底部 则自杀
ship_hit：[飞船受到alien/石头撞击后]如果剩下生命，那么生命值-1 并清空当前所有的子弹/敌机石头，本机的位置重置；如果不剩下生命了，就把积分和当前日期保存在rank中并对积分进行降序
update_bullets：子弹位置的更新，调用check_Bullet移除超出屏幕的点，并调用check_bullet_alien_collisions检查子弹和敌机的碰撞
check_bullet_alien_collisions 检查子弹和敌人、子弹和石头、子弹和bonus是否碰撞 [
Groupcollide(A,B,bool1,bool2) 多精灵A和B 如果bool1/2 为 TRUE 则 A/B消失 否则保留] 统计被碰撞（打中）而小时的敌机/bonus数量，增加对应的积分和金币，敌机等的数量会减少，如果数量小于某个阈值 进行create_XXX即可 在这里石头和bonus有一定的触发几率才会产生
其中的aliens、stone和bonus类：（非常相似）
