Alpha Blending Sprites and Background   Topic List   < Prev Topic  |  Next Topic >
Reply < Prev Message  | 
Hello,

i am working on a little action adventure type game demo at the moment. It
uses 2 background-playfields to achieve a priority effect (i.e. Sprites
going behind tree's). Also it uses alpha blending for object shadows. Now i
have added a third (alpha-blended) background to show shadows of clouds
flying over. It works fine, except where the object-shadows and clouds are
overlapping. It shows the original color of the "shadow-sprites" at this
areas. Is there a way to get around this? I included a screenshot to show
the problem. Unfortunately the problem doesn't appear on boycott advance
(which i used to make the screenshot), so i added 2 shadows (bright yellow
areas) by myself to show where it appears.

many greetings,
Andy
