A.D.A. Amiga Demoscene Archive

Thanks to the datastorm guys for a great party!

Great (and totally unexpected) demos from Norway too. Glad to see that the angry retired bastard decided to be just an angry bastard for a while =)

Perhaps datastorm will be the place for amiga releases in the future?

@dodge : sorry about this. It is because I don't have a graphics card and I'm using some bitplane fx which I didn't 'port' into the rtg blit (or what it is). So anything < 8 bpl effects get garbled.

@Dalton : thanks for lending us your machine at the party! Now that I'm back home it seems completely random what machines the demo runs on. On mine, it runs sometimes. On others it crashes while initing. Others crash right after init. Bah..

Fine demo from you too, load.Nice looking tunneleffect and a cool movement used for the doteffects.Yes,Norway is back on the Amiga map again with....wow,2 active groups - just like the Danish scene :-)

loaderror: final version runs fine on my machine, allthough it seems to require more memory than the party version. I could not run it from ram-disk on my 64mb this time

@Corial : thanks.

@Dalton : I'm working on getting the memory consumption down. I think this is the problem on my machine. If I remove some parts from the init, it runs without crashing.

So guys, are you in for Revision then ?

I'm probably not. Might drop scenestuff altogether this easter, or maybe combine one night at Eastergarden with visiting friends + a festival in Oslo instead.

@dodge : I'm not sure yet. It seems like other small events are piling up in the same time frame so maybe I'll drop scene this easter too. If something, I would like to try some pc stuff maybe. Just bought myself a powerful laptop with all the features so I should try to use it for something other than UAE too.

Uploading a version which requires less ram atleast now. Fixes my crashing problems.

@loady & slummy:
That's quite a pitty. After what I saw, I hoped for some thrilling on-screen particle battle with Kiero.

About interfering events. Yeah, Dirtie and I (as we're cousins) had the same thing last year in summer, which usually leads us to Evoke. BUT, it drove us to the decision to go with Novel's plan of invading Denmark :D

@loady
It works perfectly now, thx!
Great electro-feeling, smooth flow and veery nice fx! :)

@slummy: can you give me the exact credits for Norwegian kindness, more precisely where doMenace and Quisten fit in?

The "most correct" credits would be:
me - code, graphics, design
Lug00ber - music
Quisten - graphics, design
Menace - design

Quite an impressive amount of "design" considering the small discussion that's been running the pouet thread. ;) What it means in this case is things like color choices, movements/cameras, sync and "sitting next to Slummy and providing input while the demo is being put together at Datastorm".

@slum
That's not a discussion, it's just the usual Wade farting. ;P

Does anyone know who did the music of spaceballs demo ? Norwegian Kindness ?

AFAIK Lug00ber and the Hanggai Band did the soundtrack. It's called Khan and can be downloaded here

Btw, if there's any real interest then I might write a couple of short pieces about some of the different effects in the demo. What form it'll take (forum post, article, blog, ..) and when I'd get around to it is still up in the air though.
Right now I'm mostly interested in whether everyone will go either:
1) "duh, we already know what you did there!"
2) "duh, who cares about your black background crap?"
or 3) "ok then, we'll listen if it's that important to you"

So far 9/10 cases where people have told me their guesses have been horribly wrong though. Which of course pleases me to no end ;)

Note to Stingray: you don't count, you know how to disassemble & crack stuff!

I'd definitely be interested :)

Probably all be over my head but I can still stare in wonder at the explanations :D

ze zmoke mon ami, ze cloud-smoke si vous plait ... just for the fun of it.

Cool, I'll do it. :)
Don't hold your breath though, there's a couple of other things I have to spend time on first (nothing exciting, only real-world stuff)

Yay, a guessing competition! :-D Let me try:

You render the effects to some of the bitplanes and have a static color gradient (different for each scene) in the other bitplanes. In some scenes, the dithering of the gradient in clearly visible. In others, it is remarkably unremarkable.

No?

You're right about that part, but that's not an actual effect! ;)
But yes, this approach is used in all parts except the grey version of the clouds and the voxel-twister.
The overlays are either 3bpl (the parts with cubes + the "volume grid") or 2bpl (the rest).
How visible the dithering is does indeed depend on the chosen palettes, although it'd been a lot better if I had gotten around to animating the overlays as well (at 50Hz, obviously).

Now get on to the interesting bits instead. ;)

There were interesting bits in the demo? =)

Me me, I wanna guess... Some parts had additive sprites? You might have used the overflow bit masking trick to blend 4 pixels in one go? And with a 6bpl c2p you don't even lose accuracy since there are up to 2 bits for overflow above the colour data. One part also had scanline distortion by changing the scroll registers in the copperlist? Probably in every vblank?

Britelite: Sorry if it didn't entertain you. Next time I promise to only copy stuff people did 15 years ago. :)

Dodke:
The particles at the end use the 4pixel saturating add trick.
The other blended things don't, as 1) there's a bit of per-pixel action I couldn't be arsed to unroll. and 2) I was playing around with some more "complex" blend modes, so it's done using shade tables (2D LUTs) instead. That looked crap though (or at least I couldn't get it to look ok in time for the deadline) so it got scrapped.

And you're right about the scroll registers of course, but it was used in 2 parts, not one :)

angry retired bastard: yeah, touché :) it's better to copy stuff people did only 10 years ago =)

You know, whoever's closest to the future when the lights come on wins! ;)

@ Angry Retired Bastard:

Thanks for the info regarding the demo.

I'm probably doing something stupid, but I can't get it to run properly. I have set WinUAE up as A600, with AGA, 3.0 ROM, 68060 CPU, 2MB chip RAM, 8MB fast RAM and 128MB z3 RAM (demo's usually work better with loadsa RAM!), but I get as far as the cloud part (and the text "We're Spaceballs - you;re not"). The screen goes black and the music continues to play for about 4 minutes and then cuts out.

Can you (or anyone else) please tell me the specs needed to run the demo?


Regards,
Lonewolf10

PS. First (lame) demo by Digital Dalmation coming soon...

I would recommend setting it up as *a1200* rather than a600. :)
Other than that your setup looks sensible, it's the same I use to run the demo in UAE, so no idea why it doesn't work for you. The demo only requires 2MB chip and 16 (or maybe as low as 8) MB fast.
The problem you're seeing also happened on the "bad"(ly configured) a1200 first used in the compo at Datastorm (i.e. the one that also crashed with the EPh demo).
