Re: [pygame] question about Rect objects

[Alex Hall <mehgcap@xxxxxxxxx>]

Okay, so to sprite or not to sprite... More reading. In the meantime,
do you have a place where I can find an example of drawing a grid of
Rects? Also, I would still like to put a rect into a boardSquare
object (an object I have defined) so I can call something like
board[i][j].Rect.changeColor(red) where changeColor is a method I
implement. Is this not possible / a huge waste of resources? Again, I
come with no prior experience or reference for anything like this.
Thanks for answering my newbie questions. :)
