Massively Interleaved Sprite Crunch

I wrote a technical description of one of the new effects in Lunatico: Massively Interleaved Sprite Crunch (MISC).

Enjoy!

Very nice. I love the sprite collision register is used to fast calculate the sprite crunch. Thats brilliant!

Agreed, very nice use of the collisions to encode the y expand values.

This is some interesting stuff!
Although, I have to admit that my experience reading the article ended up a bit like this...

Heh, ending with a naughty book flip? The passion.

Honestly, too complicated for me to implement too, but Linus's articles are very educational and interestingly written. I'm sure we'll see other implementations using the same techniques, but with a different approach and visual outcome. We, the spectators, will benefit too.

Yes, that was of course tongue-in-cheek, the article is very well written., and after a couple of more read throughs I think I understand more and more.

The first time I read it though it was very much like the video. Started reading the "Background" part - "A sprite is a small piece of graphics, 24 x 21 pixels in size, that can be placed anywhere on the screen." and thought, yeah, this is surely 1+2=3 stuff, I'm gonna start skimming ahead a bit.
Then I ended up at the graph showing the connections and something about collision registers being used and whatnot and I quickly realized that I probably need to scroll back up to 1+2=3 again and start reading! :)

Very nice!! :). The only thing that puzzles me is why you picked the loops of length 14, 17, 19 and 21. Does that really give you a smooth wobble effect? If i were to pick myself, i would probably have chosen 17-21, and possibly also 1, which could perhaps simulate a loop of length 22.

Then i understand that you probably need multiple versions of the font, plus the bitmap gfx.. hmm.. Video bank getting stuffed quickly.. :P.

This article should have been released in a diskmag first! ;)

Lovely use of collision register to get what you need.
