Say in your dwarfiness, you completed your ultimate dream: A completely underwater fortress. It is completely sealed on all sides by water. But you have created this way to get outside:

Without Lever pulled:

..^^^^^^^^^
XlllllllllllllllllllllllllllllllllX---> Fortress
XlllllllllllllllllllllllllllllllllX--->
..VVVVVVVVVVV

This drawing is of two bridges, each supported by one column a Z level down, that will raise in the direction the arrow points. On both sides are floodgates, one leading to a tunnel to the outside world, the other to your fortress proper. They are 2 units tall and however many units wide.

Above this, a retractable bridge would cover the entire walkway one Z level up. However, this would only happen when activated.

As you can guess, the water will flood this area, keeping your fortress safe.

Now, is there a way to raise the drawbridges to create walls to an airlock, expand the retractable bridge on top to create a roof, and somehow, maybe 1 Z level down, expand another bridge to create the bottom of this airlock? A method of moving or destroying the liquid would need to be devised, but is this possible in any way? Just an idea I thought up in my spare time.

It works. That is what I was doing before I abandoned my project(I couldn't obtain enough Black Bronze, which I was buildign the walls out of)

YES!

YES!

that is dwarven battle bread for you.

Couldn't you build drawbridges all the way down to the bottom?  Wouldn't they destroy the water in the system when they lower?

[darkflagrance]

This is what I was thinking as well. At least, shouldn't the water that was formerly in the bridge's area be obliterated?

Are you suggesting that dwarven battle bread is food?! Thats ridiculous!

On topic though, You could use an aquifer to destroy the water in the airlock couldn't you?

Wouldn't "making rocks out of food" be more appropriate for dwarven battle bread?

While reading your post, I thought of this:

Code: [Select]

___________
_bBBBBBBBB_
##7777777##
##7777777##
##7777777##
##7777777##

_ = floor
# = wall
7 = pressurized water
b = 1-tile drawbridge, raises <-
B = 7-tile drawbridge, raises ->

When the bridges are up, the passage floods with the pressurized water.
When they lower, the long bridge crushes the water, and blocks more water from getting in.
Also makes a good drowning trap.

^^ Well played sir. That would indeed work.

Perhaps I'm having a hard time understanding your diagram but wouldn't this leave water in the floor squares at the very top?  I'm also confused as to how the B bridge would block further water from entering unless it raised towards the bottom.

As to a water destroying airlock: floodgates destroy water when they close, but won't close on an object (ie: dwarf).

Therefore, a dwarf enters a room comprised of raised floodgates. They all lower, then raise, leaving a dwarf in a 7/7 cube of water, which can easily spread out.

The only question is will the dwarf drown in the 200 or so steps the floodgates take to trigger?

I tried this as a possible way to drain a lake.  Problem is, it quickly got *super* tedious to hook up the floodgates to levers.  There isn't an easy way to do it that I'm missing is there?

Also I'm almost positive the dwarf will survive 200 steps of water.  Might depend on toughness?  I've had particularly cool dwarves survive long enough to learn how to swim, I've also had goblins do that.
