isometric tilemaps
Isometric tilemaps have two tile heights. The first one is the actual height in the tilesheet. The second height is the tile height to use when mapping them all out, since a tile can cover other tiles behind it. The second mentioned tile height is the amount to advance on the Y-axis when a new line is started. The first height is used from the tilesheet.
In the image below, a 8*8 isometric tilemap is displayed.
