Instantiate, Prefabs, Classes

I’m trying to do some basic OOP, I’m just not sure how I’m supposed to do it.

In main.js I want to make an array of Tile

Tile is a prefab, but should also be its own javascript class with it’s own methods and properties and instantiated game object.

What type of script do I need to attach to the Tile prefab to give it methods like test. And how should I instantiate each Tile in its constructor? I want to do something like this (none of this works right now):

private var tiles:Tile[,];
for(var x=0;x<width;x++) {
    for(var z=0;z<width;z++) {
        var tile:Tile = new Tile(x, z);
        tiles[x,z] = tile;
        tile.test(); // each tile should have this method which just does Debug.Log('test')

So, I finally came up with an alright solution to this, after looking up a million things. This is way more complicated than it should be.

public static Tile Instance (int something) {
	GameObject go = (GameObject)Instantiate(Resources.Load("Tile"));
	Tile instance = go.GetComponent<Tile>();
	instance.something = something;
	return instance;

Now I can just do this wherever

Tile tile = Tile.Instance(5);

Trying to do this stuff in the constructor doesn’t work.

You are trying to create a MonoBehaviour using the 'new' keyword. This is not allowed.

So I had to make my own arbitrary static Instance method. I have to be missing something, this seems like a total hack.
