@ready : no, I didnt mean randomly.

In Arcanum, there's this part where you have 5 arcanum logo's in different colors that mix colors when the overlap. When the part starts, the logo's get drawn (like a human would do with a pen).

I used that function to make that. First, I drew the logos in say blue, and then I remove the pixels (in drawing order) and the tool will record the pixel coordinates. Then you reset and save the coordinates and you can draw your logo in your part using the coordinates.

ready: Your multiplier only needs to be coprime with (in your case) 8000, i.e. it should share no prime factors with 8000. Since 8000 has prime factors 2 and 5 (2^6 * 5^3 = 8000), a non-prime such as 3*7=21 also works. This also explains why a factor of 2 won't work -- neither will a factor of 5 or any multiple of these, fwiw.

so the $c000 thing is for popping up / fading out the logo pixel by pixel randomly, right?

I have stepped into a similar problem recently (you'll see the result soon :) ) and came up with a pseudo random routine that randomly re-arranges a certain sequence of n numbers in n steps.
Let's say you have numbers 0-7999 to be picked at ramdom, but without repeating any of them and without checking what numbers you have picked to make sure you don't repeat any.
Pick a prime number, let's say 17. first item is 17, second is 17*2, thrid 17*3,... when 17*x>7999, then the item is 17*x-7999, next one is 17*x-7999+17 and so on.
Garanteed it'll pick all 8000 numbers once in 8000 steps, in a pseudo random manner. Also by changing the prime number, a different sequence is generated. Best results with prime numbers close to 7999.
Does not work with prime number 2.

I am sure this is nothing new and I did not invent anything, but discovering things on your own is always cooler :)

I really don't get what you mean with your $c000 story :-)

little bit improved version of the v1.25 that was already on CSDb. I found this on my disks, so why not share it.

There's not that many improvements, but the main ones are :

-O -> option to swap colorbits (ie, swap %00 with %01 or whatever)

and there's also a kinda hacked-in feature that i used to make the edges of the logo's move in Arcanum.

What this does is that it records the coordinates of every black (or whatever color is set with F1) pixel that is set. Coordinates are stored pairwise (x,y) from $c000 and beyond. (f.e. set a black pixel at position 0.0 and the program will write $00,$00 to $c002 (there must be a little bug, because it's supposed to be $c000 ;))

Very useful to make things pop-up slowly in exactly the way YOU want them to :)..

The way i did it : I first draw whatever i want in blue pixels, then when I'm happy, i start to remove the logo by drawing black pixels in the correct order.. Reset, and save $c000->whatever the last adress is..

have phun :)
