i think don't - alpha works with opacities from all channels, not 100% of one or another specificly
i think you can't get, for example, with alpha channels, over a #FFFFFF background, having a #FF0000 and #00FFFF sprites overlapped, a #000000 colour, which would be the needed result... but maybe Pygame or SDL have different ways (modes) to work with alpha channels, which i don't know any of them at all? ----------------------------------------------------------------------------------------------------------------------------------------- On Mon, Jul 28, 2008 at 6:29 PM, Knapp <[EMAIL PROTECTED]> wrote: > On Mon, Jul 28, 2008 at 3:01 PM, Paulo Silva <[EMAIL PROTECTED]> wrote: >> how fine were being Pygame on anaglyph games like this? >> http://youtube.com/watch?v=C00TlFHld0o >> >> Is the only way doing like this, using the red channel in the odd >> lines and green/blue in even (stuff not very hard to do, btw...), or >> can we really work on separated colour channels? >> If someone know snippets, working games, etc., please let me know... >> >> thanks! :-) >> > > Could you not do it with alpha channels? > > -- > Douglas E Knapp > > http://sf-journey-creations.wikispot.org/Front_Page >
