tile size

[franck569]

hello,

what are the tile size supported by the NDS ? only 8x8 ?

I have test to change the tile size of the example.bmp ( 06 - map.lua )
The original size of tile of this bitmap is 16x16, so i have run this command :

DSLua-0.5-emulateur\scripts>..\bin\gfx2gba -m -p map_examplescrn.bmp.pal -t16 map_examplescrn.bmp
=======================
gfx2gba Converter v0.15
-----------------------
(C) 2oo1-2oo3 [TRiNiTY]
=======================

Reading: map_examplescrn.bmp      (320x240 pixel, 256 colors)
Number of tiles before optimization: 0300
Number of tiles after  optimization: 0022
Saving tiled raw bitmap data to: map_examplescrn.raw ... ok
Saving map data to: map_examplescrn.map ... ok

Saving masterpalette to..: map_examplescrn.bmp.pal ... ok

Total files read & converted.:   1
Colors used before converting:  14
Colors used after converting.:  14
Colors saved.................:   0

As you can see, no error for gfx2gba.

After i have modified this line ( line 24 ) :
BGBottomMap:LoadMap( "map_examplescrn.map", ( 320 / 8 ), ( 240 / 8 ) )

by :
BGBottomMap:LoadMap( "map_examplescrn.map", ( 320 / 16 ), ( 240 / 16 ) )

But the result on the screen was not very good :



So, if anybody can help me,

Thanks, Franck569.

this limit is this of PAlib ?

It's a limit of the Nintendo DS. If you want another size you need to do by software.

hum, are you sure ? GBA can display 16x16 no ?

Thanks, Franck569.

hum, are you sure ? GBA can display 16x16 no ?

Thanks, Franck569.

Yes, I am quite sure, Nintendo DS and GBa have similar 2D hardware, and both only have 8x8 pixels tile maps. Maybe you confound sprite sizes, that can be 16x16, with tile sizes.
