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 win32con
from win32.win32api import getsystemmetrics
class 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,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
def update(self):
self.rect.y+=self.speed
class 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。
