    • postSolve

      public void postSolve(Contact contact, ContactImpulse impulse)
      Description copied from interface: ContactListener
      This lets you inspect a contact after the solver is finished. This is useful for inspecting impulses. Note: the contact manifold does not include time of impact impulses, which can be arbitrarily large if the sub-step is small. Hence the impulse is provided explicitly in a separate data structure. Note: this is only called for contacts that are touching, solid, and awake.
      Specified by:
      postSolve in interface ContactListener
      Parameters:
      contact -
      impulse - this is usually a pooled variable, so it will be modified after this call

    • preSolve

      public void preSolve(Contact contact, Manifold oldManifold)
      Description copied from interface: ContactListener
      This is called after a contact is updated. This allows you to inspect a contact before it goes to the solver. If you are careful, you can modify the contact manifold (e.g. disable contact). A copy of the old manifold is provided so that you can detect changes. Note: this is called only for awake bodies. Note: this is called even when the number of contact points is zero. Note: this is not called for sensors. Note: if you set the number of contact points to zero, you will not get an EndContact callback. However, you may get a BeginContact callback the next step. Note: the oldManifold parameter is pooled, so it will be the same object for every callback for each thread.
      Specified by:
      preSolve in interface ContactListener
      Parameters:
      contact -
      oldManifold -
