moving superscopes randomly
ive made a preset that is in the shape of an atom, it has 8 electrons orbiting around the edge of it and they only show up on the beat, but they are always in the same position, and even though i have added this in the per frame box: t=t+0.1+(rand(b))/0.5, they all move the same amount aroun their orbitals.

any assistance in this would be greatly appreciated.

Had you searched the forums? I've answered this to another person...

Rand(b)? omg...

Here's the template :

Beat : tx1=rand(401)/1000-0.2;ty1=rand(401)/1000-0.2;
Frame : tx=tx+tx1;ty=ty+ty1;
Pixel : x=(code)+sin(tx);y=(code)+sin(ty);

I think that's all...

i see what you mean but tthats not what i wanted, that moves them randomly all over the place, i need them to continue orbiting in a circle, but at random speeds, and directions.;)

Try this simple method:

beat: q=rand(120)
frame: t=t-0.3*below(q,50)-0.5*above(q,40)*below(q,80)+0.7*above(q,70)

In the example above you will get five different speeds. If q is greater than 70 then the direction will change.

Hope it helps;)

thanks but i figured it out, i just modified a combination of the vibrating worm and vertiacl bouncing scope and now its direction and speed are compleatly random. :D:D:D

but thanks anyway :up:


init n=800;t=0; tq=0.1;wt=1;q=0.5
beat tq=(rand(100)/100)*wt; wt=-wt;q=-q
frame t=t+q*0.9+tq*0.1;ym=cos(t)/1.9;xm=sin(t)/1.9
point r=(t+i*3.14159*4000+v); x=xm+cos(r)/100; y=ym+sin(r)/100;
blue=abs(b);red=0;green=b

Welcome.
I could have told you to search the forums or check the FAQ but I figure it's not that hard to type a few words. If you don't want to help someone out just don't write anything, don't start getting all annoyed about it. :mad: Right?

Go to AVS Discussion . Perhaps you'll find some useful info there.:up:
