How to avoid objects bouncing and overlapping after collision?

hmm, after all your bumps I finally watched your video. It actually shows the problem well, and you show the inspector which is great. I would have to load that script and see how it works, and apparently mass is one of the factors that can be affecting the other non-kinematic rigidbodies (as well as imparting velocity by the collision on the other rigidbodies). Have you tried it without using a physics material, or even making your own physics material with no bounciness (create > Physic $$anonymous$$aterial)?

But in the meantime there is another script on the Unity Wiki that claims to be better than the Standard Asset script. Save your scene as a new scene with a different name, then try this script : http://wiki.unity3d.com/index.php?title=DragObject

You are right about the mass factor: it's increase leads to bounce reduce, but it also slows down drag speed, that makes user interaction uncomfortable.

I haven't tried to create new physic material, I'll try it with changing drag script and post results.

Thank's for your advices.

I had another couple of thoughts. This is only some untested theories, but maybe you can

• 1/ tell the other rigidbodies to Sleep :

• 2/ set the other rigidbodies velocity to zero :

here are my ideas in a script form :

 //on collision enter / stay / exit
 function OnCollisionEnter( other : Collision ) 
 {
     // find the other rigidbody
     var rBody : Rigidbody = other.collider.gameObject.GetComponent( Rigidbody );
     
     // check there is a rigidbody
     if ( rBody )
     {
         //Debug.Log( "other has Rigidbody" );
         
         // check if the other rigidbody is$$anonymous$$inematic is false
         if ( !rBody.is$$anonymous$$inematic )
         {
             //Debug.Log( "other Rigidbody is NOT $$anonymous$$inematic" );
             
             // then tell it to sleep
             //rBody.Sleep();
             
             // or tell it that its velocity is now zero
             rBody.velocity = Vector3.zero;
         }
     }
 }
 
 
 //on collision stay
 function OnCollisionStay( other : Collision ) 
 {
     // find the other rigidbody
     var rBody : Rigidbody = other.collider.gameObject.GetComponent( Rigidbody );
     
     // check there is a rigidbody
     if ( rBody )
     {
         //Debug.Log( "other has Rigidbody" );
         
         // check if the other rigidbody is$$anonymous$$inematic is false
         if ( !rBody.is$$anonymous$$inematic )
         {
             //Debug.Log( "other Rigidbody is NOT $$anonymous$$inematic" );
             
             // then tell it to sleep
             rBody.Sleep();
             
             // or tell it that its velocity is now zero
             //rBody.velocity = Vector3.zero;
         }
     }
 }
 
 
 //on collision exit
 function OnCollisionExit( other : Collision ) 
 {
     // find the other rigidbody
     var rBody : Rigidbody = other.collider.gameObject.GetComponent( Rigidbody );
     
     // check there is a rigidbody
     if ( rBody )
     {
         //Debug.Log( "other has Rigidbody" );
         
         // check if the other rigidbody is$$anonymous$$inematic is false
         if ( !rBody.is$$anonymous$$inematic )
         {
             //Debug.Log( "other Rigidbody is NOT $$anonymous$$inematic" );
             
             // then tell it to Wake Up !
             rBody.WakeUp();
         }
     }
 }
