And what is "loads"?
I think you might be working from some out-of-date docs, Nathan. I suggest
that you use this (current) version of the pygame docs:
http://www.pygame.org/docs/ref/sprite.html
Here's a working (and almost minimal) pygame sprite-based program (tested
with Python 3.1 and 2.6):
import sys, pygame
pygame.init()
screen = pygame.display.set_mode((200,50), 0)
arial = pygame.font.SysFont( 'arial,microsoftsansserif,courier', 16 )
sprite1 = pygame.sprite.Sprite()
sprite1.image = arial.render('Hello, world!', True, (50,50,50))
sprite1.rect = sprite1.image.get_rect()
sprite1.rect.topleft = (20,10)
sprite_group = pygame.sprite.OrderedUpdates()
sprite_group.add(sprite1)
while True:
event = pygame.event.wait()
if (event.type == pygame.constants.QUIT):
pygame.quit()
sys.exit()
screen.fill((240,240,240))
sprite_group.draw(screen)
pygame.display.update()
Here's almost the same program, but with an event loop that doesn't wait
forever for an event; the changes are in red:
*import sys, pygame*
*pygame.init()*
*clock = pygame.time.Clock()*
*screen = pygame.display.set_mode((200,50), 0)*
*arial = pygame.font.SysFont( 'arial,microsoftsansserif,courier', 16 )*
*sprite1 = pygame.sprite.Sprite()*
*sprite1.image = arial.render('Hello, world!', True, (50,50,50))*
*sprite1.rect = sprite1.image.get_rect()*
*sprite1.rect.topleft = (20,10)*
*sprite_group = pygame.sprite.OrderedUpdates()*
*sprite_group.add(sprite1)*
*while True:*
* for event in pygame.event.get():*
* if (event.type == pygame.constants.QUIT):*
* pygame.quit()*
* sys.exit()*
* screen.fill((240,240,240))*
* sprite_group.draw(screen)*
* pygame.display.update()*
* clock.tick(60)*
This is the same as the first version, except with a resizable window:
*
import sys, pygame
pygame.init()
scrsize = (200,50)
screen = pygame.display.set_mode(scrsize, pygame.constants.RESIZABLE)
arial = pygame.font.SysFont( 'arial,microsoftsansserif,courier', 16 )
sprite1 = pygame.sprite.Sprite()
sprite1.image = arial.render('This window is resizable', True, (50,50,50))
sprite1.rect = sprite1.image.get_rect()
sprite1.rect.topleft = (20,10)
sprite_group = pygame.sprite.OrderedUpdates()
sprite_group.add(sprite1)
while True:
event = pygame.event.wait()
if (event.type == pygame.constants.QUIT):
pygame.quit()
sys.exit()
elif event.type == pygame.constants.VIDEORESIZE:
# this program is in a resizable main window; this event happens
when it's resized
scrsize = event.size # or (event.w, event.h)
screen = pygame.display.set_mode(scrsize,
pygame.constants.RESIZABLE)
screen.fill((240,240,240))
sprite_group.draw(screen)
pygame.display.update()
