jit.phys slow down to stop

    Hi, does anyone know why with friction 0. and dumping 0. 0. my ball slow down to stop?
    Thanks

      not sure why this happens, but make sure you check out the phys.body.velocity example patch that demonstrates how to query and control the velocity of a rigid-body:
      Max6/examples/jitter-examples/render/physics/phys.body.velocity.maxpat
      you probably want to make sure you are upgraded to 6.0.8 too.

      Thank you this solves my problem :)

      Controlling velocity is a good workaround but maybe it is better fix the problem around restitution
      I searched in the Bullet forum and i found this thread http://bulletphysics.org/Bullet/phpBB3/viewtopic.php?f=9&t=7922&hilit=restitution
      the administrator speak about:
      "enable split impulse, it will prevent the added energy (velocity) from penetrations.
      Code:
      m_dynamicsWorld->getSolverInfo().m_splitImpulse = true;"
      Is possible to control split impulse in jitter?
      Thanks

      thanks for digging that up!
      i will look at implementing this as an option to phys.world.

      I'm happy if this can help you
      I wait for news
      thanks

      Hi, I'm looking for a solution to disable object penetration
      here a simple example of the problem, I would like the ball doesn't pass through the plane.
      Thank you for your help

      hi
      you could increase "fixedtimestep" and "maxsubsteps"
      there is a good explanation here :
