== Missing Information ==

From the Pressure Plate page: "(See the individual device pages for complete details of how open and close signals affect each device.)"

This page is lacking *complete* details about how signals effect bridges. I'm not sure myself so would prefer someone else add the information. -[[User:AnnanFay|AnnanFay]] ([[User talk:AnnanFay|talk]]) 01:24, 9 February 2015 (UTC)

== Value calculation ==

It would be interesting to add something about value calculation of bridges. Does someone know what multipliers are used? In my case for example, my finely-designed and finely-built bridge had 25 displayed added (5*stone blocks) and 125 architecture. Is that simply x5 for the design then? I personally don't know, otherwise I'd add it myself.--[[User:Afghani84|Afghani84]] ([[User talk:Afghani84|talk]]) 07:11, 12 March 2015 (UTC)

You definitely cannot safely extend an otherwise supported C-menu construction alongside a bridge safely in version 0.47.04. You must still build it in sections, extending out from already built parts, same as you always had to, to avoid unsupported portions adjacent to the bridge being built before the parts that support them.

I've been playing Dwarf Fortress on and off since the days when you needed to make sure you didn't excavate too large an underground area to avoid it caving it, so I am well versed in avoiding cave-ins. I have just started playing 0.47.04. I had this exact situation come up. I figured there was no reason for me to be micromanaging things I no longer needed to micromanage if the game had advanced, which it has in so many ways.

Here is what I had:

 > ╚══════╝
 > +++++xxx
 > +...+xxx
 > +...+xxx
 > +...+xxx
 > +++++xxx

The south end of the bridge is to the north of a constructed floor, actually the top of a wall around a windmill. The squares marked x are where I wanted to build a 3x5 constructed floor, which would have been perfectly safe to designate all at once if the bridge were not there (except I would have needed to build a ramp by the wall for dwarf access). In older versions with the bridge there I would have had to carefully designate and build the five sections to the west, then designate the middle five once those were finished, and finally the last five. That was how I was going to do it, but then I remembered reading something about how it was now safe to extend otherwise supported constructions alongside a bridge. So I reread this page, then confidently designated the entire floor.

I figured the worst that would happen is that I would learn the wiki was wrong. Which is exactly what happened.

I have generally found this wiki to be reliable. Could someone versed in editing here please fix this, amending the cited section so it says whatever it was supposed to say--I'm not even sure what the intent of the last sentence of my quoted passage is if not sabotage, though I trust someone wrote it with a valid reason--but without conveying misinformation?

:The article wording dates back to the [[v0.34:Bridge|v0.34 version of the article]], and hasn't changed much since then. I think these two statements are saying the same thing (or are intended to):
:* From the article: "extending a supported construction alongside a bridge will not cause a cave-in"
:* From you: "You must still build it in sections, extending out from already built parts"
:I'm guessing what happened is that your dwarves tried to build sections of the floor that were accessible from the bridge, but were not yet connected to a supported construction, thus causing a cave-in. If this is what happened, the issue was that you were connecting the floors next to the bridge to an ''uncompleted'' construction, not a ''supported'' construction (which must be completed by definition). At any rate, the statement in the article is not "sabotage" or "misinformation". It could be clarified that constructions actually need to be built to provide support, so I'll try to add some wording to emphasize this. &mdash;[[User:Lethosor|<span style="color:#074">Lethosor</span>]] ([[User talk:Lethosor|<span style="color:#092">talk</span>]]) 20:29, 25 October 2020 (UTC)

:: Thank you. The previous wording made it seem that a designation that was safe in the absence of the bridge would also be safe in its presence, which isn't true. Your wording is clear. I've signed up, as you can see, and have contributed some new text and corrected clear errors, but I am still reluctant to change things where I am uncertain of what was meant without a much better feel for the community.

== Draw Bridge Blocking Liquid while both down and up ==

I don't know if this is a new bug or not, but I don't see it listed here. Feel free to delete this is this is a known issue.

A drawbridge built over channels normally prevents liquid from flowing into the channel when down, but allows the liquid to flow into the channel when up. However, it seems that if you use the drawbridge to "atom-smash" any liquid on it's level (ie above the channels) and then raise the bridge again, the bridge will continue to block liquid from flowing into the channels even when raised.

I just had this happen with my obsidian generator, and I'm not sure what to do to allow liquids to flow back into the channels. I think I may need to deconstruct the bridge.

:UPDATE - I worked out what was going on with the above "bug." Apparently you can't remove the ground layer under a bridge after the bridge is built. If you dig a ramp under the bridge you will get the ramp, but the ground layer above it will not be removed. What was happening in my case was that I was digging out obsidian under the bridge using ramps, without realizing that this left the ground layer above the ramp, so it looked like the bridge stopped allowing liquids past even when raised.

-The lever on off states should be per item on the wiki I've been thinking for a long while, as you probably know there are a number of exceptions to the general convention so it feels like it belongs more to the items page rather than a central one that tries to list all items.
-I'd be happy to write a short section (adapted from the lever on off states page) I guess the best place to get this agreement would be over on that page's discussion?
