Object generator?

I'm currently developing a simple 3D game for iPhone and I'm need of an "object generator". Basically I have an object with a script in it and i want a new copy of it to appear at a random location every second.

How would I go about doing this?

Thanks in advance!

You simply need to write a script that every second instantiates your object prefab somewhere in the scene.

Here's the function: http://unity3d.com/support/documentation/ScriptReference/Object.Instantiate.html

Here's the reference on prefabs: http://unity3d.com/support/documentation/Manual/Prefabs.html

For "spawn a model every second", you can do something simple like this (C#):

public GameObject objectPrefab;

void Start()
{
    StartCoroutine( SpawnObjects() );
}

IEnumerator SpawnObjects()
{
    while( true )
    {
        Instantiate( objectPrefab, /*however you need to determine a valid random position*/, Quaternion.identity );
        yield return new WaitForSeconds( 1.0f );
    }
}

}
