I$\text{'}$d like a breakdown of this Pong code to get a better understanding of how it

all works. In terms of functions, $\_\_$init$\_\_,$ self, etc.

Thank You!! Code:

import pygame

SCR$\_$WID, SCR$\_$HEI $=640,480$

class Player$()$:

$\_$counter $=0$

def $\_\_$init$\_\_($self$,$ x$,$ num$)$:

self.id $=$ Player.$\_$counter

self.speed $=3$

self.padWid, self.padHei $=8,64$

self.score $=0$

self.score$2=0$

self.scoreFont $=$ pygame.font.Font$("$imagine$\_$font.ttf$",64)$

print $($Player$.\_$counter$)$

def scoring$($self$)$:

scoreBlit $=$ self.scoreFont.render$($str$($self$.$score$),1,(255,255,255))$

screen.blit$($scoreBlit$,(32,16))$

if self.score $==10$:

print $("$player $1$ wins!"$)$

exit$()$

scoreBlit $=$ self.scoreFont.render$($str$($self$.$score$2),1,(255,255,255))$

screen.blit$($scoreBlit$,($SCR$\_$HEI$+92,16))$

if self.score$2==10$:

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

exit$()$

def movement$($self$)$:

keys $=$ pygame.key.get$\_$pressed$()$

if self.num $==1$:

if keys$[$pygame$.$K$\_$w$]$:

self.y $-=$ self.speed

elif keys$[$pygame$.$K$\_$s$]$:

self.y $+=$ self.speed

if self.y $<=0$:

self.y $=0$
