Re: [pygame] fade out surfaces

[Luke Miller <dodgyville@xxxxxxxxx>]

Hello Peter,

Thanks for all your help on this. It works for me ... kind of!

I call each it frame like thus:

s.alpha -= 5    #or sometimes s.alpha += 5
multiply_alpha(s.image, s.alpha)
draw(s.image)

Except it doesn't seem to work as expected. I think because your
compact code only fades out, not fade in. It does this by shifting the
alpha array to the right?!? I really don't know how your code works!!!
:)  Which really impresses me!

Thanks,
Luke
