DS development > [Solved]Tiles, Extended Palettes and setting color per Tile

#167090 - a128 - Sat Feb 28, 2009 3:54 pm

Just setup a font using tiles and the palette using the DISPLAY_BG_EXT_PALETTE feature. it woorks fine.

But I have no idea who to use different colors for the tiles , so I have different font colors per line

I looked thru libnds console.c code but did not get it.

are Bits 12..15 (color<<12) in a tile the color number ?!

In text modes you've got maps with 16 bits 'indexes'. Actually last 10 bits is the tile number (0-1023) and first 4 bits is the palette number to be used for the tile. So
Code:
finalindex=(palette<<12)|index;

(the two other bits are vertical and horizontal flip of the tile...)

I solved it..yes bits 12..15 are the palette number.

A good tutorial about this is
