Instantiate() not returning a handle to use created GameObject

Basic stuff not working. Trying to destroy a particle system spot effect. Create it instantiating a GO added in the inspector:

Code (CSharp):

1. GameObject instantiatedGO;
2.  
3. public void FX_KilledPuff(Vector3 pos){
4.     instantiatedGO = Instantiate (particlesKill, pos, Quaternion.identity) as GameObject;
5.     print ("Instantiated name "+instantiatedGO.name);
6.     instantiatedGO.name = "ertfg";
7.     Destroy (instantiatedGO, 1.0f);
8. }

When this is called, the particle system is created but 'instantiatedGO' is null.

 

Just fixed. Leaving this here in case anyone else hits the same problem. Passing Quaternion.identity as per the docs successfully creates the object but fails to return an object. Use source.transform.rotation (or whatever rotation) instead and the reference handle works.

Code (CSharp):

1.     instantiatedGO = Instantiate (particlesKill, pos, particlesKill.transform.rotation) as GameObject;
