title: SpriteKit: How to stop stack of nodes weighing down as more nodes are added?
body: <p>I'm creating a game where the user stacks nodes using <a href="https://developer.apple.com/documentation/spritekit/skphysicsjoint/connecting_bodies_with_joints" rel="nofollow noreferrer">SKPhysicsJointLimit</a>. This works, but the more nodes that are added to the stack, the more &quot;weighed down&quot; the stack gets and it becomes slower to move.</p>
  <p>I get this behaviour is modelled after physics, but how do I make it so the stack continues moving normally and isn't weighed down?</p>
