Hi i would like to repite or ad a new same object with pressing any key.
i have i line wich is an object moving in the window and i want add another line if you press any key.
this is my code:



line linea;
ArrayList <line> lineas;


void setup() {
  size(600, 600);

  lineas = new ArrayList();

  line l = new line();
  lineas.add(l);
  l.x=30;
}

void draw() {
  background(255);
  for (line l : lineas) {
    l.draw();
  }
}


/// And this is my simply object

class line {

  float n;
  int x;

  line() {
   
  }

  void draw() {

    n= random(width);
    line(n, x, n, height);
  }
}


Thank you.
