Flood fill for Tilemaps.
Thank you so much for this! Just what I've been looking for. One suggestion, I recommend in the tooltip for specifying the X/Y values, that you let people know that's a tilemap co-ordinate, and not a regular X/Y value. So they need to use Tilemap.PositionToTileX and Tilemap.PositionToTileY in there if they want to tap or click an area to start from.
Thanks for the info.
