I want to create a hexagonal tilemap and show regions of different height in the same screen. What ways can you think about to indicate which height a tile is on. (current, lower, higher?)
Several tilemap games avoid this by having special mountain tiles, but that allows for ~2 heights and I would like for more differentiation.
Another approach is to just draw the tiles of current height, but this does look very strange if the map is very bumpy (lot's of holes).
I have not found a nice way to whiten or blacken tiles that are lower or higher than the current viewpoint. Any ideas?
