游戲?qū)ζ聊坏倪m配
由于我使用的是筆記本所以對(duì)于屏幕來(lái)說(shuō)是進(jìn)行了縮放的，例如，我的筆記本縮放了125%
但是問(wèn)題在于我們的pygame和其他的一些庫(kù)例如selenium其實(shí)是按照100%顯示的像素來(lái)算的。所以這個(gè)時(shí)候我們需要進(jìn)行一個(gè)換算。
這個(gè)也好算： 當(dāng)前顯示像素比 = 100%顯示像素比 X 縮放比
我們只需要換算一下就好了。這里我定義了一個(gè)類(lèi)，來(lái)實(shí)現(xiàn)我們的需求，自動(dòng)檢測(cè)我們的電腦的屏幕縮放比，之后換算。

該類(lèi)主要對(duì)屏幕進(jìn)行像素適配，按照縮放比對(duì)像素進(jìn)行換算為100%顯示
示例：
RealSize = ChangeRealSize()
x=RealSize.getreal_xy(500)
此時(shí)就可以換算為當(dāng)前屏幕的像素
'''

"""獲取真實(shí)的分辨率"""
hDC = win32gui.GetDC(0)
w = win32print.GetDeviceCaps(hDC, win32con.DESKTOPHORZRES)
h = win32print.GetDeviceCaps(hDC, win32con.DESKTOPVERTRES)

游戲屏幕的繪制與飛機(jī)創(chuàng)建
屏幕繪制直接使用pygame.display.set_mode（）的bitl()繪制方法，進(jìn)行繪制。當(dāng)然這里的背景是會(huì)動(dòng)的。所以使用到了一個(gè)精靈的派生類(lèi)。
import pygame,random
from ChangeRealSize import ChangeRealSize
GetReal = ChangeRealSize()
class GameSprite(pygame.sprite.Sprite):
def __init__(self,image_path,speed=1):
super().__init__()
self.image = pygame.image.load(image_path)
self.rect = self.image.get_rect()
self.speed = speed

self.rect.y+=self.speed

def update(self):

實(shí)現(xiàn)的具體方法如下：
飛機(jī)類(lèi)的實(shí)現(xiàn)
這個(gè)我是自己定義的所以的話(huà)，沒(méi)有辦法直接使用那個(gè)自帶的碰撞檢測(cè)，我還定義了一個(gè)碰撞檢測(cè)方法。
飛機(jī)的移動(dòng)
這個(gè)和游戲類(lèi)的事件檢測(cè)配合。
具體思路是用pygame.event.get()進(jìn)行事件檢測(cè)。之后檢測(cè)到按下某一個(gè)按鍵，例如向前移動(dòng)是，就會(huì)設(shè)置向前移動(dòng)的信號(hào)，那么這個(gè)時(shí)候飛機(jī)就會(huì)一直往前走。當(dāng)松開(kāi)后，那么設(shè)置信號(hào)為假，那么飛機(jī)就會(huì)停下來(lái)。由于飛機(jī)會(huì)一直在循環(huán)里面檢測(cè)有沒(méi)有按下那個(gè)向前，所以當(dāng)你長(zhǎng)按往前時(shí)，飛機(jī)會(huì)一直往前，直到你松開(kāi)。
子彈與敵機(jī)類(lèi)
這個(gè)子彈和敵機(jī)都是精靈派生類(lèi)的子類(lèi)。所以的話(huà)就一起說(shuō)一下。
重點(diǎn)要說(shuō)的時(shí)子彈類(lèi)的碰撞檢測(cè)，和敵機(jī)的碰撞檢測(cè)。這里主要說(shuō)一下子彈類(lèi)，因?yàn)檫@個(gè)和敵機(jī)類(lèi)似。只是有些細(xì)節(jié)不一樣。

subtract_x = int((self.rect.width + self.hero_rect.height) / 2):
self.actract_hero.append(1)

子彈的話(huà)分兩種，一個(gè)是飛機(jī)子彈，一個(gè)是敵機(jī)子彈，敵機(jī)的自帶檢測(cè)碰撞。一方面是方便分?jǐn)?shù)統(tǒng)計(jì)（敵機(jī)擊中飛機(jī)幾次）了另一方面也是因?yàn)轱w機(jī)是自定義的沒(méi)有辦法用pygame的事件檢測(cè)（自帶的）
敵機(jī)的爆炸
這個(gè)其實(shí)又和飛機(jī)的爆炸類(lèi)似。
主要是檢測(cè)有沒(méi)有撞到飛機(jī)，之后通過(guò)切換圖片就好了。當(dāng)然這個(gè)時(shí)候我是開(kāi)了線程的。不然會(huì)很快閃過(guò)去，換了和沒(méi)換一樣你看不到效果。
切換圖片的函數(shù)，切換完畢，刪除這個(gè)敵機(jī)類(lèi)減少內(nèi)存消耗
游戲小彩蛋
這個(gè)其實(shí)就是一個(gè)自己的后面
具體作用就是修改自己的飛機(jī)的HP值為99萬(wàn)
當(dāng)然這個(gè)小游戲還沒(méi)有做完，無(wú)敵也有點(diǎn)無(wú)聊，玩久了的話(huà)。
