Independent stroke color & weight every new line?

in Programming Questions • 5 months ago

Hello all,

I want to create some lines and each of them, want to have a unique color and stroke which are changing with noise..

how can i achieve that?

For e.g:

void draw () {

float v = 0;

while (v < height) {

stroke (255 * noise(my_color1), 255, 255);

strokeWeight ( 10 * noise(my_size));

line(0, v , width, v);

v = v + 80;

my_color1 = my_color1 + 0.00001;

}

my_size = my_size + 0.005;

}

Is this code copied from some other, larger project?

This code doesn't even run, for the following reasons:

- You have an unmatched curly brace which causes a syntax error.

- You're using variables that you've not defined, which is also an error.

- You don't define a size for the sketch.

Maybe it would be helpful if you could describe what it is you're trying to accomplish...

Here's a sketch that draws some lines that have changing sizes and colors:

class Lyn{
float sx,sy,ex,ey,cr,cg,cb,sw;
Lyn(){
sx=random(width);
sy=random(height);
ex=random(width);
ey=random(height);
cr=random(255);
cg=random(255);
cb=random(255);
sw=random(10);
}
void draw(){
wiggle();
render();
}
void wiggle(){
sx+=random(-1,1);
sy+=random(-1,1);
ex+=random(-1,1);
ey+=random(-1,1);
cr+=random(-1,1);
cg+=random(-1,1);
cb+=random(-1,1);
sw+=random(-1,1);
}
void render(){
strokeWeight(sw<1?1:sw);
stroke(cr,cg,cb);
line(sx,sy,ex,ey);
}
}
Lyn[] lyns = new Lyn[10];
void setup(){
size(400,400);
smooth();
for(int i=0;i<lyns.length;i++){
lyns[i]=new Lyn();
}
}
void draw(){
background(0);
for(int i=0;i<lyns.length;i++){
lyns[i].draw();
}
}

I actually want to draw vertical and horizontal lines (chess like) (as much as my screen fits) and then each of the line change it's color and weight smoothly (noise)...
