Hack for "repeating" ground

RepeatGround.cs

using UnityEngine;
using System.Collections;

public class RepeatGround : MonoBehaviour
{
    public GameObject surfacePrefab;
    public GameObject soilPrefab;
    public Vector2 widthRange = new Vector2(-100, 100);
    public int numLayers = 10;

    void Start()
    {
        int rangeX = (int)widthRange.x;
        int rangeY = (int)widthRange.y;

        int min = Mathf.Min(rangeX, rangeY);
        int max = Mathf.Max(rangeX, rangeY);

        GameObject child;
        for (int y = 1; y <= numLayers; y++)
        {
            for (int x = min; x < max; x++)
            {
                child = Instantiate(y == 1 ? surfacePrefab : soilPrefab) as GameObject;
                child.transform.position = new Vector2(0.64f * x, -.64f * y);
                child.transform.SetParent(transform);
            }
        }
    }
}
