Dynamic bones are generally used to add physics-based animation to character animation, and can be used for hair,
ribbons, tails, and even clothing. Enhanced effects of original character animation.

Although spring motion can also be realized with a physics engine such as PhysX, dynamic bones generally need to
customize some motion curves to meet artistic needs. Therefore, this repository implements a custom small physics engine
to meet this requirement. This physics engine only implements particle-based spring animation, plus Capsule, Sphere,
and Plane colliders.

  var entity = createEntity(rootEntity, new Vector3(1, -1, 0), new Color(0, 0.7, 0));
  entity.addComponent(MoveScript);
  let dynamicBone = entity.addComponent(DynamicBone);
  dynamicBone.setWeight(0.9);

  entity = createEntity(entity, new Vector3(1, -1, 0));
  dynamicBone.root = entity.transform;

  entity = createEntity(entity, new Vector3(1, -1, 0));
  entity = createEntity(entity, new Vector3(1, -1, 0));
  entity = createEntity(entity, new Vector3(1, -1, 0));
  entity = createEntity(entity, new Vector3(1, -1, 0));
  entity = createEntity(entity, new Vector3(1, -1, 0));
  entity = createEntity(entity, new Vector3(1, -1, 0));
