Re: [pygame] Creating sprites on the fly?

[Thadeus Burgess]

Sure

Make a default sprite.

Hold a list of sprites in a dictionary-like class...

def __getattr__(key):
   if self.sprites.has_key(key):
 return self.sprites[key]
   else:
 return self.default_sprite

Couldn't you just load a black rectangle at startup and use that in
place of whatever sprite failed to load?

sounds like the point would be to have something to display in lieu of files
being in the wrong place or non-existent.

You'd have to do something like:

create a pygame.Surface
do Surface.fill()... etc... or use line drawing or something to create the
sprite
remember it for later, then if you do a try-catch block around your image
load, a fail could then assign the default sprite instead.
