Namasudra: Adding Bricks to the Game

In the previous step, we have added a paddle to our game. In this step, we will be adding some bricks, so that the ball can strike and break them. There might be some weird movements of the ball as I have not added too much complexity to the program. I have done so intentionally, so that the code remains simple to understand. Further fine tuning can be done and some extra features can be added like the paddle shooting the ball at different angles depending on where on the paddle the ball strikes. You can also add different levels to the game and end the game if the ball misses the paddle.

Code:

	import sys, pygame

	pygame.init()

	# Screen and Window setup
	screen_size = screen_width, screen_height = 600, 600
	logo = pygame.image.load("logo32x32.png")
	pygame.display.set_icon(logo)
	pygame.display.set_caption("Paddle 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_rect = ball_rect.move(290, 550)
	ball_speed = [1, 1]

	# Paddle setup
	paddle = pygame.image.load("paddle.png")
	paddle_rect = paddle.get_rect()
	paddle_rect = paddle_rect.move(225, 570)
	paddle_speed = 1

	# Brick setup
	brick = pygame.image.load("brick.png")
	brick_rect = brick.get_rect()
	brick_list = []
	x_offset, y_offset = 30, 20
	for i in range(5):
	for j in range(8):
	new_rect = brick_rect.move(x_offset + j * 70, y_offset + i * 30)
	brick_list.append(new_rect)

	# Game Loop
	while True:
	# Exit program
	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]

	# Paddle update
	keys = pygame.key.get_pressed()
	if keys[pygame.K_LEFT]:
	paddle_rect = paddle_rect.move([-paddle_speed, 0])
	if keys[pygame.K_RIGHT]:
	paddle_rect = paddle_rect.move([paddle_speed, 0])

	# Collision with paddle
	if paddle_rect.colliderect(ball_rect):
	ball_speed[1] = -ball_speed[1]

	# Collision with bricks
	for x in brick_list:
	if x.colliderect(ball_rect):
	brick_list.remove(x)
	ball_speed[1] = -ball_speed[1]

	# Screen update
	screen.fill(black)
	screen.blit(ball, ball_rect)
	screen.blit(paddle, paddle_rect)
	for x in brick_list:
	screen.blit(brick, x)
	pygame.display.flip()
