Question

我是面向对象编程的新手，但是我有这个Pong游戏，我想要添加的是让球随机生成。不要求任何人为我编写我的代码，只是想朝着正确的方向努力。

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


pygame.init()
mainClock = pygame.time.Clock()
WINDOWWIDTH = 620
WINDOWHEIGHT = 440
windowSurface = pygame.display.set_mode((WINDOWWIDTH, WINDOWHEIGHT), 0, 32)
pygame.display.set_caption('Pong')

pygame.font.init()
FPS = 60

  class Player(object):
     def __init__(self, x, y, padWid, padHei):
            self.x, self.y = 0, WINDOWHEIGHT/2
            self.speed = 3
            self.padWid, self.padHei = 8, 64
            self.score = 0
            self.scoreFont = pygame.font.Font("imagine_font.ttf", 64)

    def scoring(self):
            scoreBlit = self.scoreFont.render(str(self.score), 1, (255, 255, 255))
            windowSurface.blit(scoreBlit, (32, 16))
            if self.score == 10:
                    print ("player 1 wins!")
                    exit()

    def movement(self):
            keys = pygame.key.get_pressed()
            if keys[pygame.K_w]:
                    self.y -= self.speed
            elif keys[pygame.K_s]:
                    self.y += self.speed

            windowSurface.blit(scoreBlit, (WINDOWHEIGHT+92, 16))

                    print ("Player 2 wins!")
                    exit()

如果你想让球随机产生，可以使用pygame.draw.circle（）绘制乒乓球。

要随机生成它，导入Math，然后为pygame.draw.circle（）第3个参数put

（Math.randint（1，Screen.width），Math.randint（1，Screen.height））

以下是文档：
