pygame实现打飞机小游戏

效果预览

最近上实训课，写了这么一个简单的小玩意。运行效果如下：（这个是有音效的，不过这个展示不了因为这里只能上传GIF）

项目结构

游戏对屏幕的适配

由于我使用的是笔记本所以对于屏幕来说是进行了缩放的，例如，我的笔记本缩放了125%

但是问题在于我们的pygame和其他的一些库例如selenium其实是按照100%显示的像素来算的。所以这个时候我们需要进行一个换算。
这个也好算：当前显示像素比 = 100%显示像素比 X 缩放比
我们只需要换算一下就好了。这里我定义了一个类，来实现我们的需求，自动检测我们的电脑的屏幕缩放比，之后换算。

from win32 import win32api, win32gui, win32print
from win32.lib import win32confrom win32.win32api import GetSystemMetricsclass ChangeRealSize(object):'''该类主要对屏幕进行像素适配，按照缩放比对像素进行换算为100%显示示例：RealSize = ChangeRealSize()x=RealSize.getreal_xy(500)此时就可以换算为当前屏幕的像素'''def get_real_resolution(self):"""获取真实的分辨率"""hDC = win32gui.GetDC(0)w = win32print.GetDeviceCaps(hDC, win32con.DESKTOPHORZRES)h = win32print.GetDeviceCaps(hDC, win32con.DESKTOPVERTRES)return w, hdef get_screen_size(self):"""获取缩放后的分辨率"""w = GetSystemMetrics (0)h = GetSystemMetrics (1)return w, hdef getreal_xy(self,x):'''返回按照100%来算的真实的像素值'''real_resolution = self.get_real_resolution()screen_size = self.get_screen_size()screen_scale_rate = round(real_resolution[0] / screen_size[0], 2)try:x = x/screen_scale_rateexcept:#对笔记本进行适配，一般而言在100%比的机器上x不会出错x=1.25return int(x)

游戏屏幕的绘制与飞机创建

屏幕绘制直接使用pygame.display.set_mode（）的bitl()绘制方法，进行绘制。当然这里的背景是会动的。所以使用到了一个精灵的派生类。

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 = speeddef update(self):self.rect.y+=self.speedclass Background(GameSprite):def __init__(self, image_path="./Plane_Img/background1.png",flag=False):super().__init__(image_path)if flag:self.rect.y = -self.rect.heightdef update(self):self.rect.y+=1if self.rect.y >= self.rect.height:self.rect.y = -self.rect.height

实现的具体方法如下：

飞机类的实现
这个我是自己定义的所以的话，没有办法直接使用那个自带的碰撞检测，我还定义了一个碰撞检测方法。

飞机的移动

这个和游戏类的事件检测配合。
具体思路是用pygame.event.get()进行事件检测。之后检测到按下某一个按键，例如向前移动是，就会设置向前移动的信号，那么这个时候飞机就会一直往前走。当松开后，那么设置信号为假，那么飞机就会停下来。由于飞机会一直在循环里面检测有没有按下那个向前，所以当你长按往前时，飞机会一直往前，直到你松开。

子弹与敌机类

这个子弹和敌机都是精灵派生类的子类。所以的话就一起说一下。
重点要说的时子弹类的碰撞检测，和敌机的碰撞检测。这里主要说一下子弹类，因为这个和敌机类似。只是有些细节不一样。

class Bullet(GameSprite):def __init__(self,P_rect,is_hero=False,bullet_image = "./Plane_Img/bullet-3.gif",hero_rect=None):self.hero_rect = hero_rectself.bullet_image = bullet_imageself.speed = 4self.is_hero = is_heroself.P_rect = P_rectself.screen_height = GetReal.getreal_xy(800)self.screen_width = GetReal.getreal_xy(500)self.actarct_plan = Falseself.actract_hero=[]super().__init__(self.bullet_image,self.speed)self.rect.x = self.P_rect.x+((self.P_rect.width-self.rect.width)/2)self.rect.y = self.P_rect.ydef enemy_bullet(self):#可以在这里计算飞机被击中了多少次#被击中减少5点if not self.is_hero:bullet_x = self.rect.x + int(self.rect.width / 2)bullet_y = self.rect.y + int(self.rect.height / 2)hero_plane_x = self.hero_rect.x + int(self.hero_rect.width / 2)hero_plane_y = self.hero_rect.y + int(self.hero_rect.height / 2)subtract_y = abs(int(bullet_y - hero_plane_y))subtract_x = abs(int(bullet_x - hero_plane_x))if subtract_y <= int((self.rect.height + self.hero_rect.height) / 2) and \subtract_x <= int((self.rect.width + self.hero_rect.height) / 2):self.actract_hero.append(1)return Truedef update(self):if self.enemy_bullet():#直接在这里计算数字一次减少5global HERO_PLANE_HPHERO_PLANE_HP-=5# print(HERO_PLANE_HP)self.kill()if self.is_hero:self.rect.y-=self.speedelse:super().update()if self.rect.bottom >=self.screen_height-3 :self.kill()

子弹的话分两种，一个是飞机子弹，一个是敌机子弹，敌机的自带检测碰撞。一方面是方便分数统计（敌机击中飞机几次）了另一方面也是因为飞机是自定义的没有办法用pygame的事件检测（自带的）

敌机的爆炸

这个其实又和飞机的爆炸类似。
主要是检测有没有撞到飞机，之后通过切换图片就好了。当然这个时候我是开了线程的。不然会很快闪过去，换了和没换一样你看不到效果。

切换图片的函数，切换完毕，删除这个敌机类减少内存消耗

游戏小彩蛋

这个其实就是一个自己的后面
具体作用就是修改自己的飞机的HP值为99万
当然这个小游戏还没有做完，无敌也有点无聊，玩久了的话。
