Re: [pygame] Changing the size of a sprite

[SB <shandy@geeky.net>]

I use (and recommend) a loop something like this, I think it's pretty
simple and self-explanatory.  One problem I had when I was learning was
that I didn't know that all changes to a sprite's image or rect should
be done ONLY in (or from) the sprite.update() function.

...
window = pygame.display.set_mode( (800,600) )
spriteGroup = RenderUpdates()
...
while 1:
    spriteGroup.clear( window, backgroundImage )
    spriteGroup.update()
    dirtyRects = spriteGroup.draw( window )
    pygame.display.update( dirtyRects )

> def main():
> 	[non-sprite stuff ...]
> 	sganimals=pygame.sprite.Group()
> 	[creation of sprites, which add themselves to sganimals]
> 	allsprites = pygame.sprite.RenderPlain((sganimals))
> 	while 1:

> 		screen.blit(screen,(0,0))	# screen is the surface
> 		allsprites.draw(screen)
> 		pygame.display.flip()
