I work on a 2D game and I have multiple objects that the player can control.

The objects each have a RigidBody2D and a Collider, and a method OnMouseDrag() with which I can drag the objects.

I want the dragging to stop when the objects hit each other.

I tried by using this:

rigidbody2d.velocity = Vector3.zero;
rigidbody.isKinematic = true;

But the objects do not stop.

Please help!

I want exactly like this video. I tried this but it isn't work too.

I work on 2D game and I have multiple object we could control. Objectes have Rigidbody2D and Collider. I wrote 'OnMouseDrag()'. I want when object hits each other the dragging method is stop. But dragging is continue anyway. I try 'rigidbody2d.velocity = Vector3.zero;' and ' rigidbody.isKinematic = true;' It is not work. Please help. Sorry my grammar.
