Python+Pygame编写一个Pong游戏_开发_开发者

前言

这次，我们要用Pygame写一个Pong游戏

先看看效果：

Python+Pygame编写一个Pong游戏

需要的模块：Pygame

在python文件同目录下新建resources文件夹，在文件夹中新建Pong文件夹，文件夹中放入两个音频文件

代码教学

导入需要的模块

import pygame
from pygame.locals import *
import random
import sys

定义常量

COUNTDOWN=USEREVENT+1
path="resources/Pong/"

定义Class类，初始化函数内的代码：

pygame.init()
self.screen=pygame.display.set_mode((750,800))
pygame.display.set_caption("Pong")
 
self.mode="welcome"
self.ball=None
self.xspeed=0
self.yspeed=0
self.r=0
self.p1=None
self.p2=None
self.p1y=0
self.p2y=0
self.boardwidth=0
self.boardHeight=0
self.countdown=0
self.p1score=0
self.p2score=0
self.ballr=None
self.min=2
self.max=7
self.win=11
self.matchpoint=0
self.boardSpeed=self.max
self.ding=pygame.mixer.Sound(path+"ding.mp3")
self.bo=pygame.mixer.Sound(path+"bo.mp3")

定义listen函数

    def listen(self):
        for event in pygame.event.get():
            if event.type==QUIT:
                sys.exit()
            elif event.type==KEYDOWN:
                if event.key==K_k and self.mode=="welcome":
                    self.mode="playing"
                    self.ball=[750/2,800/2]
                    self.r=10
                    self.p1y=100
                    self.p2y=100
                    self.boardWidth=10
                    self.boardHeight=100
                    self.countdown=5
                    self.p1score=0
                    self.p2score=0
                    self.ballr=Rect(100,100,1,1)
                    pygame.time.set_timer(COUNTDOWN,1000)
            elif event.type==COUNTDOWN:
                self.countdown-=1
             python   if self.countdown==0:
                    self.countdown=0
                    pygame.time.set_timer(COUNTDOWN,0)
                    self.xspeed=random.randint(self.min,self.max) if random.randint(0,1)==0 else random.randint(-self.max,-self.min)
                    self.yspeed=random.randint(self.min,self.max) if random.randint(0,1)==0 else random.randint(-self.max,-self.min)
                else:
                    self.ding.play()

定义draw函数，用于屏幕显示，进入游戏时的ui：

        if self.mode=="welcome":
            self.screen.fill((0,0,0))
            ts=[
                "Welcome to Pong",
                "This game needs 2 players",
                "Press K to start"
            ]
            y=100
            for t in ts:
                to=self.print_text("simhei",35,t,(255,255,255))
                self.screen.blit(to,(100,y))
                y+=40

开始游戏后：

        elif self.mode=="playing":
            self.screen.fill((0,0,0))
            self.p1=pygame.draw.rect(self.screen,(255,255,255),(0,self.p1y,self.boardWidth,self.boardHeight))
            self.p2=pygame.draw.rect(self.screen,(255,255,255),(750-self.boardWidth,self.p2y,self.boardWidth,self.boardHeight))
            to=self.print_text("simhei",20,"Press WS to move",(255,255,255))
            to2=self.print_text("simhei",20,"Press ↑↓ to move",(255,255,255))
            tor=to.get_rect()
            tor2=to2.get_rect()
            d=10
            tor.bottomleft=d,800-d
            tor2.bottomright=750-d,800-d
            self.screen.blit(to,tor)
            self.screen.blit(to2,tor2)
  编程客栈          to=self.print_text("simhei",20,"Match Point!",(255,255,255))
            if self.matchpoint==1:
                self.screen.blit(to,(10,10))
            elif self.matchpoint==2:
                tor=to.get_rect()
                tor.topright=750-10,10
                self.screen.blit(to,tor)
            elif self.matchpoint==11:
                pygame.time.set_timer(COUNTDOWN,0)
                to=self.print_text("simhei",20,"Win!",(255,255,255))
                self.screen.blit(to,(10,10))
                to=self.print_text("simhei",20,"Lose!",(255,255,255))
                tor=to.get_rect()
                tor.topright=750-10,10
                self.screen.blit(to,tor)
            elif self.matchpoint==22:
                pygame.time.set_timer(COUNTDOWN,0)
                to=self.print_text("simhei",20,"Lose!",(255,255,255))
                self.screen.blit(to,(10,10))
                to=self.print_text("simhei",20,"Win!",(255,255,255))
                tor=to.get_rect()
                tor.topright=750-10,10
                self.screen.blit(to,tor)
            if not (self.matchpoint==11 or self.matchpoint==22):
                self.move()
                if not self.countdown:
                    pygame.draw.line(self.screen,(255,255,255),(750/2,0),(750/2,800),5)
                else:
                    to=self.print_text("simhei",72,str(self.countdown),(255,255,255))
                    tor=to.get_rect()
                    tor.midtop=750/2,50
                    self.screen.blit(to,tor)
            to=self.print_text("simhei",150,str(self.p1score),(255,255,255))
            to2=self.print_text("simhei",150,str(self.p2score),(255,255,255))
            tor=to.get_rect()
            tor2=to2.get_rect()
            tor.midtop=750/2/2,50
            tor2.midtop=750/2+750/2/2,50
            self.screen.blit(to,tor)
            self.screen.blit(to2,tor2)
            self.ballr=pygame.draw.circle(self.screen,(255,255,255),tuple(self.ball),self.r)

这里，为了可以显示文字，我们自己写一个print_text函数，用于显示文字

    @staticmethod
    def print_text(name,size,text,color):
        font=pygame.font.SysFont(name,size)
        image=font.render(text,True,color)
        return image

定义一个move函数，用于移动小球和两个玩家的“板”

    def move(self):
        if (not self.countdown) and (not (self.ballr.colliderect(self.p1) or self.ballr.colliderect(self.p2))):
            self.ball[0]+=self.xspeed
            self.ball[1]+=self.yspeed
            if self.ball[0]-self.r<=0:
                self.p2score+=1
                self.countdown=3
                self.ballr=Rect(100,100,1,1)
                self.ball=[750/2,800/2]
                pygame.time.set_timer(COUNTDOWN,1000)
            if self.ball[0]+self.r>=750:
                self.p1score+=1
                self.countdown=3
                self.ballr=Rect(100,100,1,1)
                self.ball=[750/2,800/2]
                pygame.time.set_timer(COUNTDOWN,1000)
            if self.ball[1]-self.r<=0 or self.ball[1]+self.r>=800:
                self.yspeed=-self.yspeed
                if self.yspeed<0:
                    self.yspeed=random.randint(-self.max,-self.min)
                else:
                    self.yspeed=random.randint(self.min,self.max)
                self.bo.play()
        elif self.ballr.colliderect(self.p1) or self.ballr.colliderect(self.p2):
            self.xspeed=-self.xspeed
            if self.xspeed<0:
                self.xspeed=random.randint(-self.max,-self.min)
            else:
                self.xspeed=random.randint(self.min,self.max)
            self.bo.play()
            self.ball[0]+=self.xspeed*2
        key=pygame.key.get_pressed()
        if key[K_w]:
            self.p1y-=self.boardSpeed
        if key[K_s]:
            self.p1y+=self.boardSpeed
        if key[K_UP]:
            self.p2y-=self.boardSpeed
        if key[K_DOWN]:
            self.p2y+=self.boardSpeed
        if self.p1y<=0:
            self.p1y=0
        if self.p2y<=0:
            self.p2y=0
        if self.p1y+self.boardHeight>=800:
            self.p1y=800-self.boardHeight
        if self.p2y+self.boardHeight>=800:
            self.p2y=800-self.boardHeight

再定义一个函数，用于检查是否有玩家已经到达赛点

    def checkMatchPoint(self):
        self.matchpoint=0
        if self.p1score==self.win:
            self.matchpoint=11
        if self.p2score==self.win:
            self.matchpoint=22
        if self.p1score+1==self.win:
            self.matchpoint=1
        if self.p2score+1==self.win:
            self.matchpoint=2
        if self.p1score+1==self.win and self.p2score+1==self.win:
            self.win+=1

定义用于进入游戏主循环的函数run

    def run(self):
        clock=pygame.time.Clock()
        while True:
            clock.tick(60)
            self.listen()
            if not (self.matchpoint==11 or self.matchpoint==22):
                self.checkMatchPoint()
            self.draw()
            pygame.display.update()

在类的外面，创建game对象，并进入游戏主循环

game=Game()
game.run()
