这篇教程如何利用pygame实现打飞机小游戏写得很实用，希望能帮到您。
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, win32printfrom 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, h def get_screen_size(self): """获取缩放后的分辨率""" w = GetSystemMetrics (0) h = GetSystemMetrics (1) return w, h def 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_rate except: #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=1.25 return 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,randomfrom ChangeRealSize import ChangeRealSizeGetReal = 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 def 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.height def update(self): self.rect.y+=1 if 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_rect self.bullet_image = bullet_image self.speed = 4 self.is_hero = is_hero self.P_rect = P_rect self.screen_height = GetReal.getreal_xy(800) self.screen_width = GetReal.getreal_xy(500) self.actarct_plan = False self.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.y def 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 True def update(self): if self.enemy_bullet(): #直接在这里计算数字一次减少5 global HERO_PLANE_HP HERO_PLANE_HP-=5 # print(HERO_PLANE_HP) self.kill() if self.is_hero: self.rect.y-=self.speed else: 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。 def CheatEngine(): global HERO_PLANE_HP print("HP is %d" % HERO_PLANE_HP) while 1: key = input("maybe you can input something:") if key=='break': print("enjoy your game please Bye~") return elif key=="Huterox is best": HERO_PLANE_HP=999999 print("Now your HP is %d!!!"%HERO_PLANE_HP) return完整代码 import pygame,randomfrom ChangeRealSize import ChangeRealSizeGetReal = 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 def 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.height def update(self): self.rect.y+=1 if self.rect.y >= self.rect.height: self.rect.y = -self.rect.height ········································································································ import pygame,random,time,threading,osfrom ChangeRealSize import ChangeRealSizefrom GameSprite import GameSprite,BackgroundGetReal = ChangeRealSize()GREATE_ENMEY_EVENT = pygame.USEREVENT#只能出现一次HERO_FIRE_BULLTE = pygame.USEREVENT+1 #第二个事件HERO_PLANE_HP = 300def CheatEngine(): global HERO_PLANE_HP print("HP is %d" % HERO_PLANE_HP) while 1: key = input("maybe you can input something:") if key=='break': print("enjoy your game please Bye~") return elif key=="Huterox is best": HERO_PLANE_HP=999999 print("Now your HP is %d!!!"%HERO_PLANE_HP) returnclass Base(): '''飞机的初始化样式，位置''' def __init__(self,x,y,width,height,path): self.x = GetReal.getreal_xy(x) self.y = GetReal.getreal_xy(y) self.width = GetReal.getreal_xy(width) self.height = GetReal.getreal_xy(height) self.image = pygame.image.load(path) self.rect = pygame.Rect(self.x,self.y,self.height,self.width)class Planer(Base): def __init__(self,x,y,width,height,path,screen): Base.__init__(self,x,y,width,height,path) self.Killed = False self.screen = screen self.GoStrange=False self.TurnLeft = False self.TurnRight =False self.GoBack = False self.Fire_flag = False self.Boom_path="./Plane_Img/hero_blowup_n{}.png" self.bullet_group=pygame.sprite.Group() pygame.time.set_timer(HERO_FIRE_BULLTE,250) self.Plane_need_Killed=[]#由于会重复执行只能去用列表的数量来判断 def Move(self): if self.Killed: self.rect=pygame.Rect(0,0,0,0) return if self.GoStrange: if self.rect.bottom <= 300: self.show() return else: self.rect.y -= 3 self.show() if self.TurnLeft: if self.rect.x<=3: self.show() return else: self.rect.x-=2 self.show() if self.TurnRight: if self.rect.x>=Game.screen_x-self.rect.width-3: self.show() return else: self.rect.x+=2 self.show() if self.GoBack: if self.rect.bottom>=Game.screen_y-30: self.show() return else: self.rect.y +=2 self.show() self.show() def Get_bullet(self): #子弹加载 if self.Killed: return if self.Fire_flag: MusicPlay().PlayPlanSound() bullet = Bullet(self.rect,True) self.bullet_group.add(bullet) def Fire(self): #子弹发射 if self.Killed: return self.bullet_group.update() self.bullet_group.draw(self.screen) def Goal(self): pass def show(self): if self.Killed: return Game.screen.blit(self.image,self.rect) # pygame.display.update() def __plane_Boom(self): if self.Killed: return for i in range(1, 5): self.image_path = self.Boom_path.format(i) self.image = pygame.image.load(self.image_path) time.sleep(0.3) time.sleep(1) self.Killed =True def Plane_Live(self): if self.Killed: return global HERO_PLANE_HP if HERO_PLANE_HP<=0: HERO_PLANE_HP =0 self.Plane_need_Killed.append(1) if len(self.Plane_need_Killed)==1: t = threading.Thread(target=self.__plane_Boom) t.start()#音乐播放类class MusicPlay(): def __init__(self): self.bgmusic = pygame.mixer.music def PlayBg(self): self.bgmusic.load("./music/PlaneWarsBackgroundMusic.mp3") self.bgmusic.set_volume(0.3) self.bgmusic.play(-1) def StarBg(self): self.bgmusic.stop() def PlayPlanSound(self): self.PlayPlaneMusic = pygame.mixer.Sound("./music/hero_fire.wav") self.PlayPlaneMusic.set_volume(0.2) self.PlayPlaneMusic.play() def StopPlayPlanSound(self): pass#子弹类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_rect self.bullet_image = bullet_image self.speed = 4 self.is_hero = is_hero self.P_rect = P_rect self.screen_height = GetReal.getreal_xy(800) self.screen_width = GetReal.getreal_xy(500) self.actarct_plan = False self.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.y def 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 -
