Bouncing Ball Example with PyGame

Here is simple code to get you started with bouncing a ball against the boundaries of the window. I have used two images, one for the icon of the application and one for the ball. The image files are given under the code for you to download and use with the code. Download the image files and put them in the same folder where you save the code.

Code:

	import sys, pygame
	pygame.init()
	# Screen and Window setup
	screen_size = screen_width, screen_height = 720, 320
	logo = pygame.image.load("logo32x32.png")
	pygame.display.set_icon(logo)
	pygame.display.set_caption("Bouncing Ball")
	screen = pygame.display.set_mode(screen_size)
	black = (0, 0, 0)
	# Ball setup
	ball = pygame.image.load("ball.png")
	ball_rect = ball.get_rect()
	ball_speed = [1, 1]
	# Game Loop
	while True:
	for event in pygame.event.get():
	if event.type == pygame.QUIT:
	pygame.quit()
	sys.exit()
	# Ball update
	ball_rect = ball_rect.move(ball_speed)
	if ball_rect.left < 0 or ball_rect.right > screen_width:
	ball_speed[0] = -ball_speed[0]
	if ball_rect.top < 0 or ball_rect.bottom > screen_height:
	ball_speed[1] = -ball_speed[1]
	# Screen update
	screen.fill(black)
	screen.blit(ball, ball_rect)
	pygame.display.flip()
