Collisions not detected under mouse control

Hey Guys,

Have posted this in answers aswell so really hoping for a response if poss....

To keep this simple, I have set up 2 objects to collide ( a sphere and a cube).I have set them both to have rigidbodies and the cube to be kinematic. I have also turned on the sphere's gravity. When I run, the sphere falls onto the solid cube and comes to rest as intended.

However, when I add a mouse control script (see below) to the sphere and move it around, it just passes right through the cube.

Can anyone shed any light on why this might be and how to resolve?

Thanks in advance.........


void OnMouseDrag()
{

Vector3 mousePosition = new Vector3 (Input.mousePosition.x, Input.mousePosition.y, distance);
Vector3 objpostion = Camera.main.ScreenToWorldPoint (mousePosition);

transform.position = objpostion;


}

 

Hey Kinematic disregard physics; therefore, does not detect the collisions. http://docs.unity3d.com/ScriptReference/Rigidbody-isKinematic.html
