Looping for structures

This is the good stuff

Example 7

• ps.defaultSpringStrength
• ps.defaultSpringRestLength

PSystem ps;

Particle p1;

void setup() {
  size(500,500);
  ps = (PSystem)loadPlugin("PSystem");
  
  Particle p2 = null;
  
  ps.defaultSpringRestLength = 5;
  ps.defaultSpringStrength = 0.2;
  
  p1 = new Particle();
  p1.setPos(100, height/2, 0);
  p1.fix();  
  ps.addParticle(p1);
  for (int i = 0; i < 10; i++) {
    p2 = new Particle(100+i*20, height/2, 0);
    ps.addParticle(p2);
    ps.addSpring(p1, p2);
    p1 = p2;
  }
  p2.fix();
  
  ps.setGravity(0.2);

}

void loop() {
  background(#99CCCC);
  p1.setPos(mouseX, mouseY, 0);
  ps.draw();
}
