I have a game where the worlds generate by generating noise made up of random tiles, and then it smooths out those tiles using cellular automata. The way it does this is the cellularAutomata function detects the amount of neighbours of each kind for each tile and stores it in 2d int arrays and then the smoothTiles function accesses the count from the 2d arrays and changes what each tile should be based off of the number. In the start function the script runs the smoothTiles function the amount of times that the int smoothCycles is. In the editor I set smoothCycles to 5, but it only seems to do one smoothing iteration. Are there any problems with my script that any of you can see?

```

using UnityEngine.Tilemaps;
public class worldGen : MonoBehaviour
{
public int smoothCycles;
public Tile water;
public Tile ground;
int[,] waterCount;
int[,] groundCount;
public Tilemap tilemap;
public int width = 100;
public int height = 100;
public Tile[] tileTypes;
void Start()
{
genRandomTiles();
cellularAutomata();
for (int i = 0; i < smoothCycles; i ++)
{
smoothTiles();
}
}
void genRandomTiles()
{
for (int x = 0; x < width; x++)
{
for (int y = 0; y < height; y++)
{
int rand = Random.Range(0, tileTypes.Length);
Vector3Int pos = new Vector3Int(x, y, 0);
tilemap.SetTile(pos, tileTypes[rand]);
}
}
}
void cellularAutomata()
{
waterCount = new int[width, height];
groundCount = new int[width, height];
for (int x = 0; x < width; x++)
{
for (int y = 0; y < height; y++)
{
List<TileBase> neighbours = new List<TileBase>();
for (int i = -1; i < 2; i++)
{
for (int j = -1; j < 2; j++)
{
int neighbour_x = x + i;
int neighbour_y = y + j;
if (i == 0 && j == 0)
{
}
else
{
Vector3Int pos = new Vector3Int(neighbour_x, neighbour_y, 0);
neighbours.Add(tilemap.GetTile(pos));
}
}
}
for (int i = 0; i < neighbours.Count; i++)
{
if (neighbours[i] == water)
{
waterCount[x,y]++;
}
else if (neighbours[i] == ground)
{
groundCount[x,y]++;
}
}
}
}
}
void smoothTiles()
{
for (int x = 0; x < width; x++)
{
for (int y = 0; y < height; y++)
{
Vector3Int pos = new Vector3Int(x, y, 0);
if(waterCount[x,y] > 4)
{
tilemap.SetTile(pos, water);
}
else if (groundCount[x,y] > 4)
{
tilemap.SetTile(pos, ground);
}
}
}
}
}
