can anyone help me with this? i am having trouble making a simple way to detect if a ball hits a paddle and then bounce it by changing the rect_change_y variable. here is code that works but the ball does not interact with paddle or die when it hits the bottom of the game.
import pygame
black = ( 0, 0, 0)
white = ( 255, 255, 255)
green = ( 0, 255, 0)
red = ( 255, 0, 0)
rect_x = 10
rect_y = 250
pad_x = 350
pad_y = 480
ball = 3
rect_change_x = 1
rect_change_y = 1
pad_x_c = 0
pygame.init()
size=[700,500]
screen=pygame.display.set_mode(size)
pygame.mouse.set_visible(0)
pygame.display.set_caption("Breakout Recreation WIP")
done=False
clock=pygame.time.Clock()
# -------- Main Program Loop -----------
while ball != 0:
# ALL EVENT PROCESSING SHOULD GO BELOW THIS COMMENT
for event in pygame.event.get(): # User did something
if event.type == pygame.QUIT: # If user clicked close
done=True # Flag that we are done so we exit this loop
keys = pygame.key.get_pressed() #checking pressed keys
if keys[pygame.K_LEFT]:
pad_x_c -= 2
elif keys[pygame.K_RIGHT]:
pad_x_c += 2
else :
pad_x_c = 0
# ALL EVENT PROCESSING SHOULD GO ABOVE THIS COMMENT
# ALL GAME LOGIC SHOULD GO BELOW THIS COMMENT
# ALL GAME LOGIC SHOULD GO ABOVE THIS COMMENT
# ALL CODE TO DRAW SHOULD GO BELOW THIS COMMENT
# First, clear the screen to white. Don't put other drawing commands
# above this, or they will be erased with this command.
screen.fill(black)
# Draw the rectangle
pygame.draw.rect(screen,white,[rect_x,rect_y,15,15])
pygame.draw.rect(screen,white,[pad_x,pad_y,50,10])
# Move the rectangle starting point
rect_x += rect_change_x
rect_y += rect_change_y
pad_x += pad_x_c
# Bounce the ball if needed
if rect_y > 480 or rect_y < 10:
rect_change_y = rect_change_y * -1
if rect_x > 680 or rect_x < 5:
rect_change_x = rect_change_x * -1
if pad_x <= 5 :
pad_x_c = 0
if pad_x >= 645 :
pad_x_c = 0
# ALL CODE TO DRAW SHOULD GO ABOVE THIS COMMENT
pygame.display.flip()
clock.tick(100)
pygame.quit ()
and then here is code that should work (to me) but doesnt.
import pygame
black = ( 0, 0, 0)
white = ( 255, 255, 255)
green = ( 0, 255, 0)
red = ( 255, 0, 0)
rect_x = 10
rect_y = 250
pad_x = 350
pad_y = 480
ball = 3
rect_change_x = 1
rect_change_y = 1
pad_x_c = 0
pygame.init()
size=[700,500]
screen=pygame.display.set_mode(size)
pygame.mouse.set_visible(0)
pygame.display.set_caption("Breakout Recreation WIP")
done=False
clock=pygame.time.Clock()
# -------- Main Program Loop -----------
while ball != 0:
# ALL EVENT PROCESSING SHOULD GO BELOW THIS COMMENT
for event in pygame.event.get(): # User did something
if event.type == pygame.QUIT: # If user clicked close
done=True # Flag that we are done so we exit this loop
keys = pygame.key.get_pressed() #checking pressed keys
if keys[pygame.K_LEFT]:
pad_x_c -= 2
elif keys[pygame.K_RIGHT]:
pad_x_c += 2
else :
pad_x_c = 0
# ALL EVENT PROCESSING SHOULD GO ABOVE THIS COMMENT
# ALL GAME LOGIC SHOULD GO BELOW THIS COMMENT
# ALL GAME LOGIC SHOULD GO ABOVE THIS COMMENT
# ALL CODE TO DRAW SHOULD GO BELOW THIS COMMENT
# First, clear the screen to white. Don't put other drawing commands
# above this, or they will be erased with this command.
screen.fill(black)
# Draw the rectangle
pygame.draw.rect(screen,white,[rect_x,rect_y,15,15])
pygame.draw.rect(screen,white,[pad_x,pad_y,50,10])
# Move the rectangle starting point
rect_x += rect_change_x
rect_y += rect_change_y
pad_x += pad_x_c
# Bounce the ball if needed
if rect_y == pad_y:
if rect_x == pad_x:
rect_change_y = rect_change_y * -1
if rect_y > 490:
ball -= 1
rect_y = 250
rect_x = 10
rect_change_x = 1
rect_change_y = 1
if rect_y < 10:
rect_change_y = rect_change_y * -1
if rect_x > 680 or rect_x < 5:
rect_change_x = rect_change_x * -1
if pad_x <= 5 :
pad_x_c = 0
if pad_x >= 645 :
pad_x_c = 0
# ALL CODE TO DRAW SHOULD GO ABOVE THIS COMMENT
pygame.display.flip()
clock.tick(100)
pygame.quit ()
finally, any suggestions on how to make the blocks and do the same thing to them, except destroying them instead of the ball?
Thanks Everyone!
