Instantiating more than one column(array)?

Hi everyone,

I’ve come up with a way to instantiate a specified amount of objects in a grid-like manner. For example, If I want 10 cubes placed exactly side by side(10 units apart from each other), I instantiate the cubes like such:

public GameObject basePrefab;
public int columnSize = 3;
public GameObject[] column;

// Use this for initialization
void Start () {
	column = new GameObject[columnSize];
	InstantiateBase(columnSize, basePrefab);

void InstantiateBase(int c, GameObject b) {
	Vector3 startPos = new Vector3(0, 0, 0);
	for(int i = 0; i < c; i++) {
		GameObject newBase = Instantiate(b, startPos + (Vector3.left * 10 * i), Quaternion.identity) as GameObject;

But this only instantiates the cubes in a straight line. How do I make it so that it instantiates like a grid? so multiple columns at a time?

Use a multidimensional array.
