Unity project Parser error

Question

I am am having trouble with a piece of code from a tutorial i found online. i keep getting a parser error by the line public static Vector2 .

Here is the the code below. I can't find anything wrong with it and would love suggestions on why this error keeps coming up. Thanks!

using UnityEngine;
using System.Collections;

public class Grid : MonoBehaviour {
    // The Grid itself
    public static int w = 10;
    public static int h = 20;
    public static Transform[,] grid = new Transform[w, h];
}
public static Vector2 roundVec2(Vector2 v) {
    return new Vector2(Mathf.Round(v.x),
                       Mathf.Round(v.y));
}
public static void deleteRow(int y) {
    for (int x = 0; x < w; ++x) {
        Destroy(grid[x, y].gameObject);
        grid[x, y] = null;
    }
}
public static void decreaseRow(int y) {
    for (int x = 0; x < w; ++x) {
        if (grid[x, y] != null) {
            // Move one towards bottom
            grid[x, y-1] = grid[x, y];
            grid[x, y] = null;

            // Update Block position
            grid[x, y-1].position += new Vector3(0, -1, 0);
        }
    }
}
public static void decreaseRow(int y) {
    for (int x = 0; x < w; ++x) {
        if (grid[x, y] != null) {
            // Move one towards bottom
            grid[x, y-1] = grid[x, y];
            grid[x, y] = null;

            // Update Block position
            grid[x, y-1].position += new Vector3(0, -1, 0);
        }
    }
}
public static void decreaseRow(int y) {
    for (int x = 0; x < w; ++x) {
        if (grid[x, y] != null) {
            // Move one towards bottom
            grid[x, y-1] = grid[x, y];
            grid[x, y] = null;

            // Update Block position
            grid[x, y-1].position += new Vector3(0, -1, 0);
        }
    }
}
public static bool isRowFull(int y) {
    for (int x = 0; x < w; ++x)
        if (grid[x, y] == null)
            return false;
    return true;
}
public static void deleteFullRows() {
    for (int y = 0; y < h; ++y) {
        if (isRowFull(y)) {
            deleteRow(y);
            decreaseRowsAbove(y+1);
            --y;
        }
    }
}

Answer 1

Looks like you are closing the class after line:

public static Transform[,] grid = new Transform[w, h];
}

Move the brace to the end of the file.

Also, any reason why everything is defined as static ? A MonoBehavior is intended to be an instance object attached to a game object.

Answer 2

Try this: You are closing the class to early and

public static bool isRowFull(int y) {
    for (int x = 0; x < w; ++x)
        if (grid[x, y] == null)
            return false;
    return true;
}

is missing brackets on the for loop.
