2 shiffmann chains using toxiclib verletphysics doesnt work?

MartinVDL

Using the example from toxiclibs I tried to instantiate a second chain using the Chain class just to see if it works. It doesnt. One chain seems to get anchored to the bottom center position. I tried creating a second Chain class (Chain2) and then renaming the class variables to avoid any naming conflicts but that still gives the same result. Any suggestions how to solve this?

TIA.

  chain = new Chain(200,20,12,.9);
  chain2 = new Chain(100,20,12,.9);

  // Update physics
  physics.update();
  // Update chain's tail according to mouse location 
  chain.updateTail(mouseX,mouseY);
  chain2.updateTail(mouseX,mouseY);
  // Display chain
  chain.display();
  chain2.display();
}

void mousePressed() {
  // Check to see if we're grabbing the chain
  chain.contains(mouseX,mouseY);
  chain2.contains(mouseX,mouseY);
}

void mouseReleased() {
  // Release the chain
  chain.release();
  chain2.release();
