Re: [pygame] Per Pixel Alpha

["Jason Ward" <nyad55@xxxxxxxxx>]

you weren't changing the alpha value btw.  the sequence for  set_at is R,G,B,A      you had 255,0,0,0    try   255,0,0,128

This link is right on the pygame site. This reference list is brilliant and explains how to use pygame very well.

If you want to modify a lot of inividual pixel values really fast then use Surfarray. I can't remember if there was another method as well.
