Re: [pygame] newbie question--> rendeing order

[enrike@ixi-software.net]

hi sb

the problem is that i would like to keep a hierarchy. the one clicked 
goes aboveand the rest one step down.
if this would be a list i would pop the clicked sprite and the append 
it to the rendering queue so that its rendered the last one.

but this is not a list. its a group, and i am not sure that the order of 
the group affects the rendering order.

i am using the chimp example as a testing ground.

voids = pygame.sprite.Group()

allsprites = pygame.sprite.RenderPlain((voids))

If i am right i need to reshuffle the allsprite group. What i am doing 
is to remove all sprites from allsprites and then i work with 
voids.sprites() list to pop and append the selected one. later i add 
all items in voids back to allsprites.

it seems to work in the chimp example but it doesn't on a more 
complex one i am building.

suggestions?
i hope all this questions don't sound too stupid. i just started 
working few days ago and there are many things i don't fully 
understand.

thanks again
