OnCollisionEnter2D is never called

Hi!

I want to check when two objects 2D collide. Each objects have a "Box Collider 2D" and one of them has the following script:

Code (CSharp):

1. void OnCollisionEnter2D(Collision2D collision){
2.         Debug.Log("collision");
3.         if (collision.gameObject.tag.Equals ("rock")) {
4.             RotateWorld.stop = true;
5.             Debug.Log("collision with a rock");
6.         }
7. }

when the two objects collide, never call this function. If a one of them have a "Rigidbody 2D", then call this function but the object that has rigibody, is affected by the physical and I don't want this, I only want to check the collision. If I check "Is Kinematic" of the rigidbody, never call this function.

Any idea?

Regards.

 

One of the objects needs to be a non-kinematic rigidbody in order for collisions to work.

Thanks for your answer.

If you need that one of the objects has a non-kinematic rigidbody and it's affected by the physical, How I can check the collision with two objects 2D without affecting the physical?

Regards.
