This refers to row zero (where the apples should be), and <$0> refers to the different directions. (This changes compared to the existing line, since before it referred to '0-3', but '4' is no longer a range)freightimage[0-4][S,W,E,N,NE,SW,NW,SE]=./image/truck_apple_2007_tgs.<$0>.<$1>
Added benefit: If you (or someone else) want to add 'real' graphics (which just means switching some colors), you don't need to edit the dat anymore.
