40d Talk:Bridge

Does a raised bridge prevent the flow of fluids? Guess I'll experiment and see if I can answer my own question. Yvain 21:21, 29 February 2008 (EST)

Yes. VengefulDonut 04:55, 1 March 2008 (EST)

Here's a picture of a bridge that raises South, to clear up any confusion over which direction bridges raise. Basilisk 18:03, 27 March 2008 (EDT)

Items...

When a creature is crushed by a bridge, what happens to the items they had?--Lordmick134

When the bridge lowers, it completely ans permanently destroys anything it crashes on. So, there will be absolutely nothing under bridge, when it raises back.--Dorten 03:29, 4 April 2008 (EDT)

Not true! I had trapped a goblin inside a room with a bridge in it, and set the lever connected to the bridge to be repeatedly pulled. The goblin was stunned at most.--CrazyMcfobo 09:37, 16 April 2008 (EDT)

The goblin was likely flung from the bridge after stepping onto the extended bridge which then raised with the goblin still on it. Crushing is definitely an irrevocable and utter destruction. --JT 16:30, 20 April 2008 (EDT)

Channeling

Checked the channeling article, nothing there, either. I have a bridge that raises to the right to form a wall, part of my outer defensive perimeter. I was digging a channel around the fortification wall and wanted to channel under the bridge. I raised the bridge ... I cannot channel. It never creates the flashy 'this is gonna be channeled' designation anywhere where the bridge could lay over. I can channel any where else. I can also remove the bridge, channel what I want, and replace the bridge just fine. What gives? Is this a known bug? --Geofferic 02:35, 29 May 2008 (EDT)

As far as I know you can't dig on constructions. When the bridge is raised it is still considered to be constructed there. (or something like that) I had the same problem with some retracting bridges. To fix it I just removed the bridges and dug the channels, and then rebuilt them. --Lotus 10:13 (CST) June 11, 2008

Bridges as a temporary wall

I want to build a wall by pulling a lever, to block off a tunnel three squares wide. It is a mine tunnel with no channel above it.

How long should the bridge be?

It looks like this:

GarrieIrons 05:12, 3 June 2008 (EDT)

Well, you have to be careful. Don't forget, by raising a bridge, you can potentially obliterate your dwarves in the process. So try not to make it too wide. --AlexFili 05:41, 3 June 2008 (EDT)

My question is, if I make it too long will it smash into the roof or anything?GarrieIrons 06:09, 3 June 2008 (EDT)

As far as I know of, it won't smash into the roof. The only concern is that if the bridge is too long, a dwarf may get accidently crushed. --AlexFili 06:14, 3 June 2008 (EDT)

Buildings that span multiple/variable z-levels are, at the current time, not possible. So, just build a 1x3 bridge, set it to raise west or east, and you have a wall! A toggleable wall! --Savok 09:09, 3 June 2008 (EDT)

I'd suggest doing a 2x bridge, as you'll have to track down the lever anytime you're curious as to whether the bridge is up or down, as a 1x or x1 bridge looks the same raised or lowered when raised on it's short axis. (e.g. the bridge above would look the same raised or lowered.) --Edward 09:59, 18 June 2008 (EDT)

Retractable/drawbridge

How can you specify which type of bridge you want to build? --AlexFili 05:45, 3 June 2008 (EDT)

When you go to place a bridge, by default it retracts. If you press wadxs you change the direction it raises: w = north, a= west, d=east, x=south, s=retracts. I don't know how to set the direction it retracts though.GarrieIrons 06:12, 3 June 2008 (EDT)

So if it retracts, it creates an impassable wall? -AlexFili 06:15, 3 June 2008 (EDT)

No, it disappears. If it raises, it creates an impassable wall, whose direction is the same as the raise direction. Try it out.

And, Garrie, it isn't possible to set retract direction since there is no such thing. --Savok 09:09, 3 June 2008 (EDT)

Well I guess it doesn't really matter which way it retracts... although if a bridge is built outward from a cliff running east-west out to the chasm which is to the north then obviously the bridge retracts back to the edge it is anchored at (it can hardly retract back into mid-air...).GarrieIrons 23:22, 6 June 2008 (EDT)

Oh, really? --Savok 23:32, 6 June 2008 (EDT)

well I guess applying common sense to DF might not be the best idea... but common sense would [bold]suggest [/bold] the bridge retracts back to where it was built from.GarrieIrons 00:03, 7 June 2008 (EDT)

We don't use BBcode here. I don't think that even is BBcode, but it is in that style. To make bold text, type '''bold text'''.

And you're right that applying common sense to DF doesn't work. Even the least of peasants can carry thousands of pounds pebbles in a backpack. --Savok 09:06, 7 June 2008 (EDT)

Bridge-on-bridge action

I've just added a note about retractable bridges being able to be built using existing bridges as support. However I'm currently unable to test what happens when an intermediary bridge is retracted or raised (I have no stone for mechanisms!). I'm assuming that any bridges relying on the retracted/raised bridge for support will collapse, but it should be tested (and noted), if someone else has the time and inclination! Raumkraut 12:04, 14 June 2008 (EDT)

I can confirm that when the first bridge is retracted the second one deconstructs. And also if you choose to do your testing using extreme cliffs and "accidently" make 6 of your 7 dwarves stand on the second bridge then they will die a horrible death after falling 18 stories. --Makuus 16:54, 16 June 2008 (EDT)

What if you raise both of the bridges at the same time? --AlexFili 05:48, 17 June 2008 (EDT)

The same thing happens, the second bridge deconstructs again --Makuus 13:48, 22 June 2008 (EDT)

lockdown system

in one of my old forts i had a setup so if the opponent got near my bridges a lever would be pulled and the opponents would fall into the lava with a godlike imp in it, it would use multiple bridges however and i would have to rebuild atleast 1, it was sort of like a tesselation of crosses
