Creates a pit straight to the underworld.
This script creates a pit to the underworld, starting at the cursor position and going down, down down.
hfs-pit [<size> [<walls> [<stairs>]]]
The first parameter is the “radius” in tiles of the (square) pit, that is, how
many tiles to open up in each direction around the cursor. The default is
meaning a single column.
The second parameter is
1 to wall off the sides of the pit on all layers
except the underworld, or anything else to leave them open.
The third parameter is
1 to add stairs in the middle of the pit or anything
else to just have an open channel.
Note that stairs are buggy; they will not reveal the bottom until you dig somewhere, but underworld creatures will path in.
Create a single-tile wide pit with no walls or stairs.
hfs-pit 4 1 0
