Re: [pygame] Sprite colours dont maintain same palette indicies

[John Anderson <corporalmustard@xxxxxxxxx>]

Ok, got it now, it seems that I have to modify the display's palette, not the display surface to achieve the desired effect.  It's odd though, because I was fooling around with swapping the palettes on individual sprites and it seemed to work fine, its only the display surface that has this functionality, but not the display itself.

Hmm, using .setPalette() doesnt seem to help matters, perhaps it has something to do with the way I've loaded images/ converted them? I've been using the image loader from the "chimp" tut, maybe theres a flag I need to set that I havent? The images are loaded from palettized .gifs and then converted with no arguments to pixel format.

 IIRC this is the behaviour when you use .set_palette_at(). To keep
the same indices, thus changing the colours, you need to use
.set_palette() to replace the entire palette at once.
 I seem to remember having the same problem while trying to
procedurally generate some graphics.
