Disable Bouncing of Box.

  From my understanding what b2MixRestitution does is decides which restitution to use, and by default it takes max restitution from both colliding objects (or mixes them somehow). If your box has restitution 0 and ground has restitution 0, setting b2MixRestitution won't change anything. Then the problem lies somewhere else.
  
  Increasing density of object or maybe even friction might help.
  
  And of course if all fails, you can try some drastical solutions, like creating a magnet from floor

  @ar2rsawseen: Thank you so much.
  
  As in box2D's documentation: "set restitution = 0 does not guarantee that there is no bouncing". Actually I don't know where is the problem
  
  Edit: Got it, after many tries I decide to slow down box & avoid bouncing, use:
  boxBody:setLinearDamping(number)

  Try it out:

  @thanhquan1512 I've actually found out the way of overwriting the restitution.
  
  Set up the pre_solve event and inside it, retrieve contact object and modify it's restitution like this:

  function scene:onPreSolve(e) local contact = e.contact contact:setRestitution(0) end

  Don't know if it will solve your problem, but maybe it'll be useful

  I think @ar2rsawseen's solution is great. But when both box and ground have restitution = 0, it shouldn't bounce at all.
