instantiating a prefab particle system

HI Everyone,

I am getting an error from a script i have written where a particle system will spawn to simulate an object exploding.

The particles are set to instantiate when the main object is collided with. Here is the code.

Code (csharp):

1.  
2. void OnCollisionEnter2D(Collision2D other)
3.      {  
4.      if (other.gameObject.name  == "Player") {
5.        brick_boom.Play ();
6.        Instantiate (brick_pop,transform.position,transform.rotation );
7.         daBrick.enabled = false;
8.        Destroy (gameObject,2f);
9.  
10.      }
11.      }

However when i hit the object i get the error Unassigned reference exception.

I have the public ref set as brick pop and have dragged the brick explosion prefab into that slot in the inspector.

Any ideas what i am doing wrong?

Thanks

 

Can you tell in which Line the Error Occurs?
Atm i can't tell what "brick_boom", "daBrick" is,
maybe there is an error ? Any further Informations ?

 

My mistake. I had two copies of the script attached to the object. Script one didn't have the prefab attached, Causing the error

Thanks for your looking though.
