c# loops not working yet no erors

hi so ive just started learning c# and ime coming across a problem with loops where despite no erors coming up the loop dosent seem to be working if i put print in it dosent print anything out but if i put it before it dose i dont know whether its just something in c# ime un aware of but i never had this problem with Js anyway here my code its around line 40 where the problem is

using UnityEngine; using System.Collections; using System.Collections.Generic; public class MapGen : MonoBehaviour { public List<Chunk> Builders; // Create a texture and fill it with Perlin noise. // Try varying the xOrg, yOrg and scale values in the inspector // while in Play mode to see the effect they have on the noise. public int MapGenSize; // Width and height of the texture in pixels. public Transform ChunkPreFab; public int pixWidth; public int pixHeight; // The origin of the sampled area in the plane. public float xOrg; public float yOrg; // The number of cycles of the basic noise pattern that are repeated // over the width and height of the texture. public float scale = 1.0F; public Texture2D noiseTex; public Color[] pix; void Start () { // Set up the texture and a Color array to hold pixels during processing. xOrg = Random.Range(-10,10); yOrg = Random.Range(-10,10); noiseTex = new Texture2D(pixWidth, pixHeight); pix = new Color[noiseTex.width * noiseTex.height]; CreateChunks (); renderer.material.mainTexture = noiseTex; } public void CreateChunks (){ print("12"); for (int x = 0; x < MapGenSize; ++x) { // this is the part that isnt working for (int z = 0; z < MapGenSize; ++z) { print("123"); Transform clone = Instantiate(ChunkPreFab, new Vector3(x * 20, 0, z * 20), Quaternion.identity) as Transform; Builders.Add(clone.GetComponent<Chunk>()); clone.parent = transform; clone.GetComponent<Chunk>().GenScript = this; clone.GetComponent<Chunk>().BDataStore = transform.GetComponent<BlockData>(); } } CalcNoise(); } public void CalcNoise() { int y = 0; while (y < noiseTex.height) { int x = 0; while (x < noiseTex.width) { float xCoord = ((xOrg + x) / noiseTex.width) * scale; float yCoord = ((yOrg + y) / noiseTex.height) * scale; float sample = Mathf.PerlinNoise(xCoord, yCoord); pix[y * noiseTex.width + x] = new Color(sample, 0, 0); x++; } y++; } noiseTex.SetPixels(pix); noiseTex.Apply(); // Copy the pixel data to the texture and load it into the GPU. MakeMountains(); }

i thought it might be something to do with using the variables x and y multiple times in each class any help would be much aprechated
