@ Photon - thanks man - great advice, on modulos and overscan limits.

Sorry hitchhikr. I didn't realise this effect had an "official" name so I just called it something that seemed appropriate to me. Didn't mean to annoy you.

Don't worry, nobody's been annoyed

pmc · 22 April 2010, 08:23

Cool.

On the Atari ST, the scroller effect you admired in "The Cuddly Demos" (and in many other ST demos too) was known as a "DNA scroller"... while we're on the topic of naming effects

Photon · 22 April 2010, 21:51

Yeah, [ Show youtube player ]'s a tube scroller all right. (But lacking vertical and horizontal bending, so at this simplest version it's two mirrored halves of the same scrollbuffer colorized with gradients.)

And more scrollers, and more

Hehe, reminds me of some early Amiga demos that could have two big scrollers and one small one on the same screen... I was almost but not quite as bad, I think my record is two scrollers ;P

Oh, and [ Show youtube player ]'s the nice Star Wars scroller I saw at my mate's place decades ago, yay. (At least I think that's the one.)

If we dated the NS MD 2 and Knight Hawks intro correctly, they were released the same month. As I said, it wasn't an uncommon effect early on, which is why I think none of those two were first.

Scrollers are the lifeblood of the type of old skool one screen demos that are my (and probably your...?) favourite type of stuff.

Star Wars scrollers rule! That's something I definitely want to have a go at doing myself at some point.

Photon · 27 April 2010, 21:07

Found something, here might be something that is ... um ... not a tube scroller but at the same time a tube scroller. Only the year of release is known. It's a demo I saw early on, I remember. "Look at those magic logos! The Amiga is so different and best!" Hehe.

pmc · 27 April 2010, 21:25

Yeah, that's a kind of odd one. Nearly the same code wise by the looks of it but with a strange colour scheme - both front and back of the letters is coloured to bow outwards at the centre so they both look wrapped round the front of the tube.

Nice. Cheers for pointing that one out Photon.

Hi guys, I am new to the whole Amiga coding thing and I am trying to make up for my complete lack of knowledge and skill with sheer enthusiasm and bloody-mindedness. I would like to take a look at the scroller but I can't see how to access any attachments - sorry everyone but I'm new to the whole forum thing (this is only the second post I have ever made). It's bound to be something I have done or not done - can anyone help me out?

The problem is that pmc removed all attachments from this thread

Normally you see a download link at the end of the post. Quite sure that pmc will add it again after your request.

Welcome to EAB and enjoy your stay

Thanks. The scroller may seem to be a little advanced for a total ASM n00b but I tend to find that I learn best by example.

pmc · 31 August 2010, 14:55

I've gotten into the habit of deleting off attachments that I add to posts after a little while rather than leave them hanging around. Otherwise I lose track of what's where.

Like TCD says though - I don't mind reposting.

So, find attached .zip archive containing:

CoRkScReW.exe - Amiga executable of the effect

CoRkScReW_qkspn.exe - same again, only this one spins quicker, if you like that sort of thing...

CoRkScReW.68k - source code for CoRkScReW.exe so you can see how it's coded.

Like the scroller says - easy to code (I managed to make it after all!

) and quite nice to look at.

Enjoy. Oh, and if you have questions or want some help - just ask and I'll try to help you out however I can - it's always nice to have more people coding.

Thanks pmc - you're a star

Incidentally, pmc - anything to do with Pure Metal Coders or just coincidence?

No probs man - hope you enjoy it. There are far better coders on here then me (Hi Sting, hitchhikr, musashi5150, Photon, Leffmann and the rest

) but if you get stuck or need any help or want more sources and stuff then you can always drop me a note and I'll try to help you out.

LOL. If I had a penny for every time someone asked that.

Just a coincidence, pmc in my case is my initials - checking my code against the kind of stuff Pure Metal Coders made also highlights the fact that it's just a coincidence.
