[Tutor] Does Pygame allow background images?

[Liam Clarke-Hutchinson]

Oh dear, 

The full code would be (hopefully correct this time)

import sys, pygame
pygame.init()

ball = pygame.image.load("ball.bmp")
background = pygame.image.load("bckgrnd.bmp")
ballrect = ball.get_rect()
backgroundRect = background.get_rect()

size = (width, height) = background.get_size()
screen = pygame.display.set_mode(size)


while 1:
     for event in pygame.event.get():
        if event.type == pygame.QUIT: sys.exit()
        ballrect = ballrect.move(speed)
        if ballrect.left < 0 or ballrect.right > width:
            speed[0] = -speed[0]
        if ballrect.top < 0 or ballrect.bottom > height:
            speed[1] = -speed[1]

	  screen.blit(background, backgroundRect)
        screen.blit(ball, ballrect)
        pygame.display.flip()

Hi Nathan,


Just create a surface the same size as your screen, and have a loop like so 

while True:
   <move rects>
   <draw hockey rink, which erases old hockey players>
   <blit hockey players onto moved rects, which are drawn on top of hockey
rink>
   <check for input>


Here's some rough code to add a background for that ball one I posted
yesterday. Bear in mind that I can't check this at work. Lines with !! are
new-

import sys, pygame
pygame.init()

!!background = pygame.image.load("bckgrnd.bmp")#Pygame can handle other
formats. !!backgrountRect = background.get_rect() !!size = (width, height) =
background.get_size() 
#Returns size of image as (x, y) so game screen will be as big as background
screen = pygame.display.set_mode(size)

ball = pygame.image.load("ball.bmp")
ballrect = ball.get_rect()

while 1:
     for event in pygame.event.get():
        if event.type == pygame.QUIT: sys.exit()

        ballrect = ballrect.move(speed)
        if ballrect.left < 0 or ballrect.right > width:
            speed[0] = -speed[0]
        if ballrect.top < 0 or ballrect.bottom > height:
            speed[1] = -speed[1]

	  !!screen.blit(background, backgroundRect) #instead of
screen.fill()
        screen.blit(ball, ballrect)
        pygame.display.flip()


That's very basic, but it should work.

Hey all,

Does Pygame allow background images (i.e. a hockey rink for a hockey game)?

Thanks,
