Attached sprites

nirvan75 · 25 December 2015, 15:26

Hi,

can someone help me to better understand the concept of "attached sprites"?
What I understood is that a sprite can have 4 colors (including transparency) and if I want to have a 16 color sprite the only way is to use 2 sprites attached, identical in size.

But what is not clear to me is how do I create the sprite starting from the IFF, before I convert it to raw file (probably I will use PicCon for conversion from IFF to RAW and finally include the raw in ASM-ONE code).
For example: Do i have to draw my sprite with 16 colors, save it to IFF and then PicCon will create 2 attached sprite (in a raw file) for me or else?

The target is not for AGA Amigas, but older models.

Maybe if you could attach a very simple example file, it would be the best!
Thanks

It can convert from IFF to any output format you want, including hardware compatible format with control-words included for you. Open Settings->Image Format and select Sprite format and check Attached, other format options are in the Project menu.

you need to put the first two bitplanes in one sprite and the next two bitplanes in the other..

Thank you.

I successfully converted from IFF to asm .s and used the datas in my code. Next step I will try to add two more sprites in order to obtain a 32 pixel wide sprite (16 color).
