Howto: Set character pixels

Show how to set pixels to a chara, read it’s pixel to a groupeof bg cells and rewrite them to an other chara.

Note: it use ROR and ROL instead of complex bitwise operation.

Using ROR/ROL is an interesting idea.

Also because you choose to implement ROOL and not SHIFT, the bits status are saved.

I just implemented it because AMOS had it and I thought it's cool for "internal scrolling" of characters :)

Oooo, this looks sooo coool :)

Oops, I misread... I thought you had said you were reading individual pixels from the BACKGROUND data... that would be super hard to do... (and necessary for a real worms game)...

This is still cool though :)

There was WORMS on the game boy, so yes it's possible using tiles. I don't say it's the easier way though...

Yea, can be done tile wise, but give the game a “blocky” feel... worm movement should be allowed on a pixel level...

One could make everything look blocky for a variant version... that would work :)

OR, do like you have done before, create cells that differentiate half block sizes... that might complicate things though...

Actually, a freestyles bomberman version blowing up blocks but with a worms twist sound more fun to do :)

It's not that blocky: https://www.youtube.com/watch?v=3V5_Kt_QjcA

Actually, that one has pixel precision.... as the worms move along the terrain, they move precisely along each pixel beneath them... as do the round bombs when they roll along....
