Coders, please write about your work

category: general [glöplog]

Hugi#32 is in the making and getting near completion.
Share your knowledge with others for perhaps a better scene

But for the coder section we can still use some small, larger or very large
articles..

check out:

http://www.hugi.scene.org/main.php?page=topcod

for inspiration what you can write about

you can email your support to magic_nah@hotmail.com

than you for your cooperation.

coders are busy coding so they can't write large or even very large articles. \o/

ok. i'm going to share my startup code for the amiga:

-----
start:
-----

ok, and then when your demo is finished:

-----
moveq #0,d0
rts
-----

There you go.

All of the topics in the wanted articles-list can be answered with one word:

Google.

preacher: hugi#32 is by sceners for sceners

we would like articles written by demo coders
which (if possible) isnt released yet.

I am gonna share my knowledge how to destroy Xeron's startup code:

Code:


lea start(pc),a0
move.l #$4afc4e75,(a0)
rts

now you have a destroyed startup code.

added on the 2006-06-17 17:39:50 by StingRay

should be move.l #$4afc4e75,(a0) of course.

added on the 2006-06-17 17:40:41 by StingRay

i recommend adding

Code:lock xadd [esi], eax

right after stingrays code.

that stops it from assembling correctly on AT LEAST 5 different platforms.

Should it really? Let's say you just set the .radix directive. (Or wahtever your compiler calls it)

My coding article for Hugi:

--8<---8<--- cut here ---8<---8<---

I'm gonna teach you how to clear the screen. To do that, do:

Code:


for ( int x = 0; x < 319; x++ )
{
  for ( int y = 0; y < 199; y++ )
  {
    int color = 0;
    setColor( x, y, color ); 
  }
}

Now, that's easy, isn't it? But now we're gonna make the screen white, and that's a lot more difficult because to make the color white we have to count up all the way to 255!!!!!!!!!

Code:


for ( int x = 0; x < 319; x++ )
{
  for ( int y = 0; y < 199; y++ )
  {
    int color = 0;
    while ( color != 255 )
    {
      color++;
    }
    setColor( x, y, color ); 
  }
}

But here comes a nice optimisation trick. We'll secretly set the color already to 128 before we start counting!!!!!!!!!!!

Code:


for ( int x = 0; x < 319; x++ )
{
  for ( int y = 0; y < 199; y++ )
  {
    int color = 128;
    while ( color != 255 )
    {
      color++;
    }
    setColor( x, y, color ); 
  }
}

OMG WTF we have just doubled the speed of this awesome routine! Us demosceners are such 7331 h4x0r5!!!!!!!!

In the next Hugi I'll teach you how to use 2 different colors at once in only a quarter of the speed OMG WTF that's gonna be so cool!!!!!

sparcus: 319x199 is a stoopid resolution

Damn, someone noticed ;-)

added on the 2006-06-17 22:47:50 by sparcus

you should use (unsigned)(199*4.0/3.0) instead !

It takes more time to code than to write about that code.

I mean the reverse, of course.

    mov ax, 0a000h
    mov es, ax
    mov bx, pos
    mov al, col
    mov [es:bx], al
end;
end;

Procedure Box(y, x, x2, y2 : integer; color : byte);

var loopy : word;

begin
  for loopy := y to y2 do

 until keypressed;

Man, I sure wrote leet code in '94.

The scene needs fresh people who are really motivated to learn to code. However people who are enough motivated (and smart) will to code regardless of available articles.

Now, let's get back to spamming, folks!

Code:

Start
ENTRY:	jp	$150

End
	di
.loop	jr	.loop
