For the roguelike I'm developing I wish to add a gradient-like feel to the field of view of the character. To do so I decided to add a TileSet on top of the ground so that each tile would have a diferent alpha value depending on the distance to the player. It would be the same tile, just different alpha value.
However, I cant seem to find a way to modify a tile before or after placing it via code or otherwise. Is it even possible? If it's not, how could I go about my problem?
Thanks for any help!
