Creating an array of vectors in a line

Processing Coding Questions

So here’s where I’m at right now. Working on a test script for debugging/figuring this out.

I have a script that can create an array of lines, but the main issue I’m having is it actually getting the proper x and y after rotation. (or maybe it’s not actually rotating, I’m not sure.)

ArrayList<Lines> lines;
float rot = 0.0;
Lines test = new Lines(0, 0, 0, 50, rot);

void setup() {
  size(1920, 1080);
  background(0);
  lines = new ArrayList<Lines>(1000);
}

void draw() {
  stroke(255);
  strokeWeight(2);
  //test.createShape();
  for (int i = 0; i < 100; i++) {
    rot = radians(i);
    lines.add(i, new Lines(0 + i, 0 + i, 0, 100 + i, rot));
    lines.get(i).createShape().rotate(rot);
    beginShape();
    for (int j = 0; j < lines.get(i).createShape().getVertexCount(); j++) {
      vertex(lines.get(i).createShape().getVertexX(j), lines.get(i).createShape().getVertexY(j));
    }
    endShape();
    shape(lines.get(i).createShape());
    println(lines.get(i).createShape().getVertexCount());
  }
}

class Lines {
  
  float x1, x2, y1, y2, rot;
  PShape shapey = new PShape();
  
  Lines(float x1_, float x2_, float y1_, float y2_, float rot_){
    x1 = x1_;
    x2 = x2_;
    y1 = y1_;
    y2 = y2_;
    rot = rot_;
    shapey.beginShape();
    shapey.vertex(x1, y1);
    shapey.vertex(x2, y2);
    shapey.endShape();
    shapey.rotate(90);
    
    
  }
  
  PShape createShape(){
    return shapey;
  }
  
}

I also tried using your example but for a 2 vertex object, but couldn’t get the rotation to work there.

from what I’m seeing in the processing reference this should be working, so I must be missing something here.
