How to instantiate an object using both another object's location and vector3

Hi all, Is it possible to instantiate an object at another objects position and then use vector 3 to add a value to the Z axis of the instantiated object?

Umh, simply use the Instantiate() version where you can pass a position and rotation...

EDIT: As I realized now, you are trying to add an offset to the local Z of the object you instantiated, not the worldspace Z, as I assumed. The easiest way to do the former would be to use a "normal" Instantiate, and then add the offset afterwards in local space:

// this is .js UnityScript

Yes. If you construct a new Vector3 with your Z offset you can add it to the position of the other object on instantiation. Like so... (I haven't actually tried this code, but it should all be there)

var targetObject : GameObject;
var newObject : GameObject;
var offset : float = 10;
var P : Vector3 = targetObject.transform.localPosition + Vector3(0,0,offset);

newObject = Instantiate(newObject, P, Quaternion.identity) as GameObject;

Ok so i've got the following:

var roidPlusZ : Vector3 = roid.transform.localPosition + Vector3(0,0,50);

missileExplodeFire = Instantiate(missileExplodeFire, Vector3(roid, roidPlusZ, Quaternion.identity)as GameObject);

But im getting the following error: Assets/Scripts/Asteroids/AsteroidPhysics.js(40,77): BCE0024: The type 'UnityEngine.Vector3' does not have a visible constructor that matches the argument list '(UnityEngine.Rigidbody, UnityEngine.Vector3, UnityEngine.Quaternion)'.

any ideas?

roid is a rigidbody and missileExplodeFire is a particleEmitter
