World: r3wp

ie
 should be "i.e."
langage  should be language

Cool stuff!

Reichard: thanks for the report! (langage is French, I often made 
this mistake)

There's actuially no title, it was my intent. There will be later.
But you're right with jsMaths : it's *very* slow.

You spell better than me, I assure you.

I figure I will simply give you some feedback if I notice it (and 
now you know I looked at your page) : )

Reichard: ok, thank you: the page will certainly evolve this week.

Reichart: Have you seen a game called Yoomp for Atari 8bit ?
http://www.youtube.com/watch?v=TNxICcU3bPo

Well, something like that... I'm messing with that tunnel effect 
... and it works :)

kib, under "Images Like this:" on you page, it say: </strong>*ERROR 
no-value in: im-alt

Geomol: yes I know, I'm currently working on my code and it uploads 
every time my page !

Geomol: the image has been fixed; it's rather strange, I've tried 
to use locals in my function instead of global and that raised an 
error.

Looks good now. Good work!

Interesting...people still making Atari games.


One of my team makes emulators for about 15 old game machines, his 
goal is to preserve them before all is forgotten.

Good night, see you !

Vladimir, can we see what you've done so far with your Yoomp-like 
game ?

I did some special-effects demos a few years ago, maybe I can advise 
on techniques to improve it.

Well... it was supossed to be just an tunnel algorythm test and tunning... 
:)
My goal is to write Game like yoomp for C64 :)

Now when I think about it.. if I already have tunnel moving in rebol.... 
it would be quite easy to add a jumping ball to it.... :)
Will upload something usefull later in the day...

Vladimir, are you in the demo scene?

Cool, I await with baited breath.

Vlad, Good to know that there is other people involved in old computers 
revival.
I'm always coding for MSX computers . 

Last year, with Rebol, i tried to simluate the PSG AY family (sound 
processor of MSX) and  an old game (GALAGA).

I think Rebol is perfect to construct toolsets for that purpose (graphics/maps/patterns/sprites 
editors, asm preprocessor).
(see http://www.rebol.org/search.r?find=guest2&form=yes)

ah... the old good alfa rebcode

yep, i loved it very much

@Henrik: Im into demoscene :) Im one of those retrofreaks.... :) 
I made couple of never released games during 80s and 90s... As a 
matter of fact I never stopped coding for C64... Graphic routines, 
hardware projects, testing new effects.... Its a hobby for life....

@Steeve: I know your work :) I was impressed with galaga :) and I 
agree fully in using rebol as help for coding. I use it often to 
make table generators, and creating include files for c64 assembler.

wooowww, someone who like my demo, i'm flattered :)

BTW, Rebcode is  pretty good for making some pixelbased graphics. 
Cyphre made some interesting demos when it was first prototyped. 
Geomol made a voxel engine.

yeah agreed, but i'm afraid it"s not anymore possible with R3

Rebcode is the history, though, as R3 models does not provide significant 
speed-up, to be worth inclusion (said speed-up is only something 
like 3x normal REBOL code)

not yet at least. we'll see what happens in this area.

BrianH has some other ideas in mind, of how to possibly improve the 
situation though ...

for those things rebcode was limited by SHOW in R2 and lacked some 
better pixel write routines.

We'll have some decent openGl implementation... right? :)

perhaps someday if/when Cyphre comes back :-)

until than here is what can be done in rebol during two coffees... 
:)
http://www.visaprom.com/tunel.r

in my demo (galaga) , actually i was limited by by the framerate 
of show, not by the inner speed of rebcode

vladimir, very cool!

and the sound port implementation was bugy too, as we know

Not bad :) Looking code...

its rough code.... map for level should be made from tiles, and the 
moving should be twice smoother.... than it would be same as on atari....

And it uses atari resolution.... and I did scaling in software... 
each atari pixel is actually 4x4 pixels in image....
Is there a way to scale image using hardware in rebol?

no, but you can smooth image scaling

yes Vlad, your code is clean, i see the inheritance of a good asm 
coder

hehehe :) thanks.... it could be cleaner :)

maybe I didn't need that much parenthesis but thats just to be sure.... 
:)

there are probably optimizations that can be made there.

hmm, i coold try to port your code in R3 if you want

img: make image! 4x4
poke img 1x1 red
poke img 2x2 white
view layout [image img (img/size * 8)]

Just remember, this was just made to find out if  calculations made 
on a napkin in a restaurant were correct :)

This script proved my math skills are still valid and now I need 
to implement them in 6510 asm... :)
Would be nice to see it in R3..... How is vid advancing in R3 ?

it's advancing...
Acutally, it's enough to handle drawings at bitmaps level

no need of Vid for your purpose

why? is there some other way of displaying pictures in R3...?

sure, you have to use gobs, wait a minute i rewrite your code....

ok.... Ill go make coffee.... looks like coding time :)
