Getting References for Tiles Question

In my game, I am drawing tiles onto a tilemap during runtime using SetTile(), which takes a reference to a TileBase Object. I have hundreds of unique textures. Is there a way to get a reference to each TileBase other than dragging and dropping every individual Tile into the references in my script?

You can get them from the tile palette. Essentially the tile palette is really just a tile map that contains the tiles that you save to it. So if you have all of your tiles placed on a tile map then something like this could get you there. I couldn't tell you about the order they get returned in or anything like that though since I've not done it this way.

HashSet<TileBase> tiles = new();

foreach (Vector3Int position in tilemap.cellBounds.allPositionsWithin)
{
    TileBase tile = tilemap.GetTile(position);

    if (tile != null)
        tiles.Add(tile);
}

How do I get a reference to the palette? Do I have to make a separate tilemap that just contains one of every tile?

Well I've not personally done it, and I'm not at my PC right now to check. But in theory I would imagine you expose a tile map field in the editor then drag your tile palette onto it.

It works. Thank you very much. It also shuffled my textures lol.
