what is the string of code to make a variable change pls make this into this code, this is pygame btw import pygame import time pygame. init() screen = pygame. display. set_mode([800,600]) keep_going = True WHITE = (255,255,255) BLACK = (0,0,0) BALL_SPEED_X = 5 BALL_SPEED_Y = 5 score = 0 # ball variables posx = 100 posy = 100 speedx = BALL_SPEED_X speedy = BALL_SPEED_Y radius = 14 #paddle variables paddley = 300 paddlex = 1 paddle_length = 100 paddle_speed = 5 while keep_going: for event in pygame. event. get(): if event. type == pygame. QUIT: keep_going = False # ball movement posx += speedx posy += speedy if posx - radius paddley + paddle_length/2) or (posy = 1: print(" You Lose!") exit() speedx = BALL_SPEED_X speedy = BALL_SPEED_Y posx = paddlex + 10 posy = int(paddley) else: speedx = -speedx elif posx + radius >= 800: speedx = -speedx elif posy - radius = 600: speedy = -speedy # paddle movement if paddley - paddle_length/2 = 600: paddley = 599 - paddle_length/2 else: key_object = pygame. key. get_pressed() if key_object[pygame. K_UP]: paddley -= paddle_speed elif key_object[pygame. K_DOWN]: paddley += paddle_speed # draw the screen elements screen. fill(BLACK) pygame. draw. circle(screen, WHITE, (posx, posy), radius) pygame. draw. rect(screen, WHITE, (paddlex, paddley - paddle_length/2, 5,paddle_length)) pygame. display. update() # slow things down time. sleep(0.02) pygame. quit()
