inconsitencies in my first code

[wildbill]

i am trying to make a pong game i have started from scratch twice now and i am noticing that the "ball" only bounces if i hover my mouse near the point where it should bounce.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

import sys import pygame import os   pygame.init()   win = pygame.display.set_mode((600,500))   pygame.display.set_caption("pong?")     win.fill((0, 0, 0)) pygame.display.flip()   x1 = 305 y1 = 245 xvel = .05 yvel = .05     while True:       for event in pygame.event.get():         if event.type == pygame.QUIT:             pygame.quit()             sys.exit()           if y1 >= 490:             yvel *= -1                             pygame.draw.rect(win, (255, 255, 255), (x1, y1, 15, 15))     pygame.display.update()       x1 += xvel       y1 += yvel       win.fill((0, 0, 0))

You need to dedent this section back into the while loop instead of the event loop

1 2	if y1 >= 490:     yvel *= -1

to like this

1 2 3 4 5 6 7 8 9

while True:        for event in pygame.event.get():         if event.type == pygame.QUIT:             pygame.quit()             sys.exit()        if y1 >= 490:         yvel *= -1
