Object generator?

Question

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 );
    }
}

}

Thanks! So I would create a prefab "objectPrefab" in which I would put my duplicate object, where would I put this script? (Sorry I'm a bit new to all of this Unity stuff. I'm more used to programming in Objective-C)

Just create an object in the scene, put that code in a class, and attach that script to the object. That empty object will be your object generator. You'll have to attach the prefab to the input (public variable) of your script in the inspector window.
