Array of Tilemaps misbehaving
I am creating a script that generates a 2d array of Tilemaps and then runs a specific function on them that will create "caves" with a Perlin function. It was only showing up on the top left Tilemap, so I tried to see where the function was actually working by making it remove all tiles it passes over and this is what I got. 
The result I was expecting was all of the tiles to be gone. Why aren't they??
Here is the code:
At the beginning of my script I set CHUNKSIZE to 64 and define currentChunk as null. GenerateWorld is called first.
public void GenerateWorld()
{
StartCoroutine("CreateChunks");
}
Then it runs this function.
IEnumerator CreateChunks()
{
chunks = new Tilemap[Mathf.CeilToInt(xCount / CHUNKSIZE), Mathf.CeilToInt(yCount / CHUNKSIZE)];
for (int x = 0; x < xCount; x++)
{
for (int y = 0; y < yCount; y++)
{
if (x % CHUNKSIZE == 0 && y % CHUNKSIZE == 0)
{
GameObject current = new GameObject();
current.transform.position = new Vector3Int(x, y, 0);
//Sets parent here and sets up Tilemaps components
chunks[x / CHUNKSIZE, y / CHUNKSIZE] = current.GetComponent<Tilemap>();
yield return null;
}
}
}
StartCoroutine("CreateCaves");
}
Finally it runs this function.
IEnumerator CreateCaves() {
//float rand = Random.value;
for (int x = 0; x < xCount; x++)
{
for (int y = 0; y < yCount; y++)
{
if ((int)x % CHUNKSIZE == 0 && (int)y % CHUNKSIZE == 0)
{
currentChunk = chunks[(int)x / CHUNKSIZE, (int)y / CHUNKSIZE];
yield return null;
}
currentChunk.SetTile(new Vector3Int(x, y, 0), null);
//if (Mathf.PerlinNoise(x / xCount * 100 + rand * 200000, y / yCount * 100 + rand * 200000) > 0.5F)
//{
//}
}
}
}
You need to refresh the tile after setting it : currentChunk.RefreshTile(new Vector3Int(x, y, 0));
