A question on palettes/colour cycling

Post by POLYGAMe » Sat Apr 02, 2016 9:09 pm

Hi again!

Say I have an image loaded that only uses 4 colours and I have a palette of 16. Is it possible to cycle through the pallete colours instead of swapping palettes? I think this could be used for some cool effects. If this is possible, how exactly would it be done? I'm thinking it will be a good way to go for alternating lines on a 2.5D road.

Cheers!

Of course it is possible :)

You have the principle of color cycling here :
https://en.wikipedia.org/wiki/Color_cycling

What you can do as well is to actually storing 2x2bpp (4 colors images) or 4x1 bpp (2 colors) images inside a unique 4 bpp (16 colors) image. For that you have to design an image which actually use all 16 colors of the palette and contains internally the different lower colors images.

Palette animations can be very cool. You can do things like these: http://www.effectgames.com/demos/canvascycle/
