Give all the objects that you want to check if it’s the closest a tag. You should only have to change the tag of the prefab that you are instantiating from

Then just substitute “tagname” with the tag you chose for those instantiated objects.

function Update()
{
    print("Closest Object is " + GetClosestObject("tagName").name);
}

function GetClosestObject(tag:String) : GameObject
{
	var objectsWithTag = GameObject.FindGameObjectsWithTag(tag);
    var closestObject : GameObject;
    for (var obj : GameObject in objectsWithTag)
    {
        if(!closestObject)
        {
           closestObject = obj;
        }
        //compares distances
        if(Vector3.Distance(transform.position, obj.transform.position) <= Vector3.Distance(transform.position, closestObject.transform.position))
        {
           closestObject = obj;
        }
    }
    return closestObject;
}

Here is a function that should return the closest gameobject with a collider based on specific distance away from the current object’s position.

var radius : float = 50.0;  //this is how far it checks for other objects

function Update()
{
	print("Closest Object is " + GetClosestObject().name);
}

function GetClosestObject() : GameObject
{
	var colliders : Collider[] = Physics.OverlapSphere (transform.position, radius);
    var closestCollider : Collider;
    for (var hit : Collider in colliders) {
    	//checks if it's hitting itself
    	if(hit.collider == transform.collider)
    	{
    		continue;
    	}
    	if(!closestCollider)
    	{
    		closestCollider = hit;
    	}
    	//compares distances
    	if(Vector3.Distance(transform.position, hit.transform.position) <= Vector3.Distance(transform.position, closestCollider.transform.position))
    	{
    		closestCollider = hit;
    	}
	}
	return closestCollider.gameObject;
}
