I have coded an animation (in python) for a beach ball to bounce around a screen. I now wish to add a second ball to the window, and when the two collide for them to bounce off each other.
So far, my attempts at this have been unsuccessful. Any ideas how to do this? The code I have so far is below.
import pygame
import sys
if __name__ =='__main__':
ball_image = 'Beachball.jpg'
bounce_sound = 'Thump.wav'
width = 800
height = 600
background_colour = 0,0,0
caption= 'Bouncing Ball animation'
velocity = [1,1]
pygame.init ()
frame = pygame.display.set_mode ((width, height))
pygame.display.set_caption (caption)
ball= pygame.image.load (ball_image). convert()
ball_boundary = ball.get_rect (center=(300,300))
sound = pygame.mixer.Sound (bounce_sound)
while True:
for event in pygame.event.get():
print event
if event.type == pygame.QUIT: sys.exit(0)
if ball_boundary.left < 0 or ball_boundary.right > width:
sound.play()
velocity[0] = -1 * velocity[0]
if ball_boundary.top < 0 or ball_boundary.bottom > height:
sound.play()
velocity[1] = -1 * velocity[1]
ball_boundary = ball_boundary.move (velocity)
frame.fill (background_colour)
frame.blit (ball, ball_boundary)
pygame.display.flip()
