Re: [pygame] moving a filled circle from top to bottom
Hi, Kevin.
You already created the example. :) Just replace the few lines in your
__init__ method.
Note that this is not a "better" way of doing it. It's just an approach that
I find easier to work with when computing your graphics, i.e. "procedural"
graphics.
When you load your graphics from an image file, you get a surface sized to
fit the image and can get your rect from it. In contrast, when computing
your own graphics it might help to create your dimensions first (the rect)
and use the rect in plotting your graphics primitives.
Hope that explanation helps.

Hey...my apologies for taking so long to get back to you, I was staying at a
friend's house for a couple of days. I honestly don't understand your email.
Maybe you could give me a small example...if you wish.

Re: [pygame] moving a filled circle from top to bottom
Changing the order might help with procedural images. Then you can make the
rect's attributes work for you.
self.rect = pygame.Rect(0,0,50,50)
self.image = pygame.surface.Surface(self.rect.size)
pygame.draw.circle(self.image, pygame.Color(0, 0, 255),
self.rect.center, self.rect.width/2)
self.image.set_colorkey(pygame.Color('black'))
self.rect.center = 320,0

Re: [pygame] moving a filled circle from top to bottom
It's extremely minor. Change the center of your circle from (320, 0) to (25,
25). The coordinates are with respect to self.image, not to screen.
