这是我第一次写文章，和大家分享我的python程序。请大家多多点赞，觉得我写的好的话还可以关注一下我。后期我会继续多发一些文章的哦！
今天我要来介绍介绍我自己做的游戏——球球大作战！大家来看看吧！
---------------------------------------------------开始写代码了！---------------------------------------------------------
做代码前的小贴士：
首先要用cmd安装好pygame模块哦！
pip install pygame
一、初始化
首先要导入很重要的pygame,random和math模块（我用了as），初始化程序，做好界面，写上标题
# import pygame, random and mathimport pygame as pgimport random as rdimport math# init programpg.init()# set screenscreen = pg.display.set_mode((1000, 500))screen.fill((255, 255, 255))# set titlepg.display.set_caption("球球大作战", "4.0")
初始化好了程序才能进行下一步。
二、函数、方法和类的定义
程序少不了函数与类。我们得先定义好函数circle，这样方便画圆圈。
# def circledef circle(color, point, r, size):pg.draw.circle(screen, color, point, r, size)
接下来就要做球的类了。为了可以被吃，所以要用类（懂了吗？）
# class ballclass Ball():def __init__(self):self.color = (rd.randint(0, 255), rd.randint(0, 255), rd.randint(0, 255))self.x =rd.randint(0, 1000)self.y = rd.randint(0, 500)self.r = rd.randint(5, 15)self.size = rd.randint(5, 15)
然后设置好玩家操控的球和画球的列表。
# make a balllistballlist = []for i in range(600):balllist.append(Ball())# creat myballmyball = Ball()myball.color = (0, 0, 0)myball.x = 500myball.y = 250myball.size = 5myball.speed = 10
这一段的最后要做好判断按下，吃球和生成。
这里要运用上math模块，还用了勾股定理！
每过十秒生成30个球，这样就“永远”也吃不完球了
为了更真实一点，我还加了一些其它代码。越吃得多，速度就越慢。这里推荐*=0.（），想要多少可以自己调。为什么要*=呢？因为/或//要么除不进或者除到零了就麻烦了。
# def check touch# use the pythagorean theoremdef touch(myX, myY, fX, fY, myR, fR):distance = math.sqrt((myX - fX) ** 2 + (myY - fY) ** 2)if distance <= myR + fR:# just return Truereturn Trueelse:# return Falsereturn False# def foodDeliverydef foodDelivery():time = pg.time.get_ticks()# every 10 seconds put 30 foodsif time % 10000 >= 9000 and time % 10000 <= 9020:for i in range(30):balllist.append(Ball())# def draw# use "Ball" and for range to append in the balllistdef draw():for ball in balllist:if touch(myball.x, myball.y, ball.x, ball.y, myball.size, ball.size):balllist.remove(ball)myball.size += 0.1# make the speed to be smaller than the last one# use the multiplier scale decreases and inverse proportional functionmyball.speed *= 0.992else:circle(ball.color, (ball.x, ball.y), ball.size, 0)circle(myball.color, (myball.x, myball.y), myball.size, 0)
这样这一段就做好了！
三、主程序运行
接下来必须得认真了，马上就要运行主程序了。
小贴士：fps（帧率）一定要控制好，否则电脑显卡和cpu可能会卡，还要写好防卡程序，可以避免程序忽然报错或者暂停退出。
# check fps, do not quit programfps = pg.time.Clock()# check quit and play programwhile True:# do not make the fps so high# if the fps is high, the computer will ~"bomb!"fps.tick(60)event = pg.event.poll()if event.type == pg.QUIT:pg.quit()exit()
接下来要做球的移动了，要用pygame.key.get_pressed()来判断哦。
keys = pg.key.get_pressed()# make the ball to move# I use the "wasd"# also can use up down right leftif keys[pg.K_w]:myball.y -= myball.speed
“wasd”上下左右都可以，注意x,y坐标轴的加减。
# check quit and play programwhile True:# do not make the fps so high# if the fps is high, the computer will ~"bomb!"fps.tick(60)event = pg.event.poll()if event.type == pg.QUIT:pg.quit()exit()keys = pg.key.get_pressed()# make the ball to move# I use the "wasd"# also can use up down right leftif keys[pg.K_w]:myball.y -= myball.speedif keys[pg.K_a]:myball.x -= myball.speedif keys[pg.K_s]:myball.y += myball.speedif keys[pg.K_d]:myball.x += myball.speedif keys[pg.K_UP]:myball.y -= myball.speedif keys[pg.K_DOWN]:myball.y += myball.speedif keys[pg.K_LEFT]:myball.x -= myball.speedif keys[pg.K_RIGHT]:myball.x += myball.speed# the e is to update ball's xyelif keys[pg.K_e]:myball.x, myball.y = 500, 250
最后写上更新和画图的方法，整个程序就写好了！（别忘了加一次fill，这样易于更新）
while True:# do not make the fps so high# if the fps is high, the computer will ~"bomb!"fps.tick(60)event = pg.event.poll()if event.type == pg.QUIT:pg.quit()exit()keys = pg.key.get_pressed()# make the ball to move# I use the "wasd"# also can use up down right leftif keys[pg.K_w]:myball.y -= myball.speedif keys[pg.K_a]:myball.x -= myball.speedif keys[pg.K_s]:myball.y += myball.speedif keys[pg.K_d]:myball.x += myball.speedif keys[pg.K_UP]:myball.y -= myball.speedif keys[pg.K_DOWN]:myball.y += myball.speedif keys[pg.K_LEFT]:myball.x -= myball.speedif keys[pg.K_RIGHT]:myball.x += myball.speed# the e is to update ball's xyelif keys[pg.K_e]:myball.x, myball.y = 500, 250# draw and checkdraw()foodDelivery()# display programpg.display.update()screen.fill((255, 255, 255))
四、完整代码
最后奉上全部代码：

六、知识总结
通过这次编程，我们了解了如何使用pygame做游戏，也用到了许多模块和复杂的代码。
我们也从中学习到了random, math和pygame模块的运用方法，了解了pygme模块的厉害。
我们操控的球，就好像大白们和白衣天使，他们竭尽全力，与病毒（其他可以吃的球）战斗，让我们更加安全。
希望大家多多学习python，借助在家隔离的这段期间学习编程，分享程序，共克时艰，战胜疫情。
