Collision

Hi.
I'm new to unity, but made a object(Man) walking around.
Then I spread some balls(Bluberry) using this code.

Code (CSharp):

1. for (int y=0; y<numBlueberry; ++y)
2.        {
3.             GameObject inst = Instantiate(Blueberry, new Vector3(Random.Range(-20.0f, 20.0f), 1, Random.Range(-20.0f, 20.0f)), Quaternion.identity);
4.             inst.name = "Blueberry1";
5.        }

Then I try to detect collision.

Code (CSharp):

1. private void OnCollisionEnter(Collision collision)
2.     {
3.             LogCollsiionEnter.text = "On Collision Enter:" + collision.gameObject.name;
4.             //Destroy(collision.gameObject);
5.         }
6.     }

The Bluberry1 name is not appearing.
If the man walk into an other object witch is not a prefab , the name will show.

If I do the destroy it will work. But I'm not able to sort out by name or tag.

Also if I don't tick 'is trigger' the man stops when walking into a blueberry.

I have also tried collision.collider.name but same result.

What is it I'm getting when it comes to Prefabs and collision ?

I need to be able to sort on collision.

Thankful for all help.

Greeting Kaizen.

 

I found that the problem is the actual name of the prefab. Depending on some the situation (Can not figure out what is causing what) the created gameobject from prefab got a different name. Sometimes the name + (clone).
Strange behavior...
