... but only '''stone''' and metal will hold back magma.

Is this true? In the last version only steel was strong enough to contain magma. --[[User:Mizipzor|Mizipzor]] 15:29, 1 November 2007 (EDT)

: Well, my dolomite floodgates were enough to hold magma. So stone floodgates are capable of holding magma. Dunnoe about wooden ones though. [[User:Noctis|Noctis]] 15:59, 1 November 2007 (EDT)

:Not true. I used stone floodgates all the time with magma in the last version. --[[User:RedKing|RedKing]] 00:52, 2 November 2007 (EDT)

::Perhaps the confusion comes from the fact that you needed steel to bridge over magma --[[User:Moller|Moller]] 02:11, 2 November 2007 (EDT)

:::Alright, the dolomite floodgates that I've mentioned earlier seem to have disappeared, presumably melted away. Thus I'm led to belive that only steel(or better) floodgates are capable of holding magma now. [[User:Noctis|Noctis]] 09:29, 3 November 2007 (EDT)

::::From what I've seen stone floodgates are, at the moment, one use like the steel ones listed in the article...but for different reasons. A closed stone floodgate will hold back magma indefinitely (probably for the same reason that the normal stone walls hold magma as they do), but once you link and open it the magma enters the same tile and turns any stone into it's molten counterpart. This means both your stone floodgate and stone mechanism are turned to slag and eventually lost to the magma forever. I would bet that the steel floodgates are still there, but forever locked in their open state since your mechanism just got turned to goo and you can no longer select the flood gate from the lever's link menu. Perhaps [[Bauxite|Bauxite]] might be able to survive the magma, but I need to find some first in order to test that theory.{{version|0.27.169.33b}} --[[User:TheUbie|TheUbie]] 04:28, 19 November 2007 (EST)
::Interestingly enough, I do believe dolomite has a high melting point and is somewhat heat resistant...

----

Interesting note, floodgates seem to take approximately 100 steps to open after activation, from my experimentation. Maybe this could be used in the article somehow?
[[User:NullAshton|NullAshton]] 23:51, 1 January 2008 (EST)

:Ooh, interesting. Exactly the same amount as a bridge. --[[User:Savok|Savok]] 20:36, 11 June 2008 (EDT)

== opening and closing ==

do I '''have''' to use a lever to open and close a floodgate? Early on - I have a room next to a river - I want to put a floodgate in the corridor and "bucket fill" a "pond" from the outside.

will this plan work or do I '''need''' a lever?[[User:GarrieIrons|GarrieIrons]] 01:55, 5 January 2008 (EST)

:You need some kind of machine to trigger it, yes. Pressure plates work as well. --[[User:N9103|Edward]] 06:20, 5 January 2008 (EST)

== Construction ==

All right... I have a 1-wide channel, with a floodgate "placed" not "built" somewhere along it.
Access is from a stair to the right.
No matter if I put the build command closer to the stair, or further away from the stair, the dwarves seem to build the floodgate so that it cuts off their exit! WTF is one to do here? I keep ordering the dwarf that just built the floodgate to remove it so they can get out again.[[User:GarrieIrons|GarrieIrons]] 23:34, 2 February 2008 (EST)

:Hook it to a mechanism and open it. --[[User:Ikkonoishi|Ikkonoishi]] 00:59, 3 February 2008 (EST)

::Yeah well when I get a mechanic that is the general plan ;) but right now it's sitting in the middle of a channel while I prey for more immigrants before all of my dwarves die of thirst![[User:GarrieIrons|GarrieIrons]] 01:48, 3 February 2008 (EST)

:::All right, I have opening and closing floodgates now.[[User:GarrieIrons|GarrieIrons]] 07:45, 5 February 2008 (EST)

::::Would you mind posting a pic of your setup? I'm a mite confused on this also....[[User:Holyfool|Holyfool]] 22:38, 3 February 2008 (EST)

== River crossings ==

I can dam/divert a river with floodgates I hope.
If I dig a channel 1 z-level down, then build a wall, the top is a floor I can walk across. Why isn't the top of a floodgate a floor? it is silly that I have to build a floodgate then a bridge as well, and connect them to the same lever, if I want a floodgate I can walk over. (in real life even a simple drop-board weir - which is pretty mcuh a timber floodgate - can be walked over so that you can put the boards in and out).[[User:GarrieIrons|GarrieIrons]] 07:45, 5 February 2008 (EST)
:PS. I am diverting my brook by digging a channel through it while it is frozen then building a series of floodgates in the resulting channel. I guess this will work (here's for trying) but how would one divert a river?[[User:GarrieIrons|GarrieIrons]] 07:47, 5 February 2008 (EST)

::Non-freezing? Very difficult to get to work properly, dependent on the terrain of course. Basically, you'd have to dig quite a large pond/lake for the river to fill while scrambling like mad to get those dwarves to install all the floodgates or build the walls before the flow into the lake slows enough for construction-blocking waterlevels to start flowing again. Definitely suggest a stockpile immediately adjacent to the closest entry point to the downstream side of the dam to hopefully avoid a waste of time if only one or two dwarves get their lazy butts over to the work that needs to be done! As for freezing; well, that's always been child's play, and I always wonder why people bother asking someone "if the map they're on freezes," anytime someone says they need help trying to dam a flow. ;) --[[User:N9103|Edward]] 09:30, 5 February 2008 (EST)

:Well, I have dug a channel in the ice. There are some boulders left behind as well as it seems some ice blocks. I think these will be off to make a pond as ice hauling seems much more efficient to me than bucket hauling?
:But anyway, the channel is all marked as "blocked" when I try to build floodgates. Will see what it's like when the ice blocks are all gone.[[User:GarrieIrons|GarrieIrons]] 06:40, 6 February 2008 (EST)

== Floodgate swept away ==

With version 38a I noticed that floodgates can be swept away by molten rock which is pushed by the flowing lava. I don't know if this also happend with earlier versions since this was the first time, because of lack of fule and wood, that I actually used magma.
Somebody should probably mention in the article that it is advisable to remove rocks from the magma channel to prevent this. [[User:Buckermann|Buckermann]] 11:53, 9 February 2008 (EST)

:The floodgate was verified beforehand to have been built, and not simply dropped and forgotten? --[[User:N9103|Edward]] 07:39, 13 February 2008 (EST)

::I'm quite sure that it was build, and not just dropped. It was even connected to a lever and was working. For a short time at least... And I'm also quite sure that I used Bauxit mechanism for it. [[User:Buckermann|Buckermann]] 09:53, 13 February 2008 (EST)

:::A non-bauxite mech. would be my next point of inquiry, and just to make sure we're not missing the obvious, the floodgate itself was magma-proof? --[[User:N9103|Edward]] 04:14, 14 February 2008 (EST)
::::Yes, the floodgate too was made of Bauxit, and it is still visible in my magma silo. ([http://i162.photobucket.com/albums/t243/TaBu-NiW/magmachamber.png?t=1203005405 Link to image]) [[User:Buckermann|Buckermann]] 11:11, 14 February 2008 (EST)
:::::Can you reproduce this? [[User:VengefulDonut|VengefulDonut]] 12:21, 14 February 2008 (EST)
::::::No. I tried a few times to reproduce this, but never succeeded. Probably I just forgot to use bauxit mechanism the first time. Though, I would have sworn that I did. [[User:Buckermann|Buckermann]] 20:14, 8 March 2008 (EST)

== No Access ==

I dug a diagonal tunnel towards a water source and I wanted to put a floodgate inside it - and one on the end where my farm will be - to create a reservoir. But I get the message, "no access" when I try to build the floodgate inside the tunnel. Apparently floodgates can only be placed when there is horizontal or vertical access to the square? (I planned to connect a lever to it so I don't need to stand next to it.)<br />
That does indeed seem to be the case. I was able to place one in the middle of a horizontal tunnel but not in a diagonal one. I dug an extra square (ruining my perfect symmetry with an ugly dogleg :)) and was able to put the floodgate inside my diagonal tunnel. --[[User:Danny Rathjens|Danny Rathjens]] 01:15, 6 April 2008 (EDT)

== bug? ==

i wanted to water some rock below my fortress with the water from my moat, so i built a setup like this:
..~.<br>
..x.<br>
.> . surface level -1<br>
..x.<br>
..~.<br>

....<br>
.< x surface level -2<br>
....<br>

basically, the idea was that the area between the floodgates on the top level would fill with water, BUT while the top two were open, the bottom one would be closed. so i hooked up the top two to a lever, pulled it, built the third floodgate, linked that to the lever. so now my top two gates are open, and the bottom one closed. this would make sure that only the amount of water i wanted would go onto my plot. however, when i next pulled the lever, the top two closed, but the bottom one didnt open. i pulled it again and all 3 opened. so dont go doing this yourself, use two levers instead of 1. [[User:Twiggie|Twiggie]] 12:09, 16 May 2008 (EDT)

::This is intended. Levers have an "on" and an "off" state. Pulling them switches the lever state and updates all connected constructions to the new state. --[[User:Doniazade|Doniazade]] 12:47, 16 May 2008 (EDT)

== A Question on Flow and Floodgates ==

So I had my two-[[floodgate]] system for letting [[magma]] into the trench below my smelting and forging rooms, each floodgate hooked up to a separate [[lever]]. The 'downstream' gate was right next to the [[ramp]] down which the magma was meant to [[flow]]. The upstream floodgate worked fine, and the magma went into the trench fine, but when I attempted to close the downstream gate, it re-appeared at the bottom of the channel. Was it swept away by the flow as it was trying to close? What happened there? --[[User:Zombiejustice|Zombiejustice]] 19:21, 11 June 2008 (EDT)

:What material was the floodgate made out of? What material were the mechanisms made out of? It seems that the magma melted something and deconstructed the floodgate. --[[User:Savok|Savok]] 20:36, 11 June 2008 (EDT)

::It looks like this was answered higher on this page: The floodgate was made of bauxite, but the mechanism was not and must have melted once the gate was opened. Should really have seen that coming, I guess. Well, only a few rooms are full of magma, I'm sure it'll cool in a month or two. Lesson learned. --[[User:Zombiejustice|Zombiejustice]] 22:19, 11 June 2008 (EDT)

40d:Floodgate

2008-06-12T23:08:00Z

Plasma:

A '''floodgate''' is an object used to regulate the flow of fluids, such as [[water]] and [[magma]]. A [[wood]], [[stone]] or [[metal]] floodgate will suffice for water flow, but only [[magma-safe materials|magma-safe]] materials with a melting point higher than about 1200°C, such as [[bauxite]], [[steel]] or [[raw adamantine]] <small>(don't do that)</small> will hold back magma. Floodgates function much like [[door]]s with the 'Forbidden' option set at all times. Floodgates generally have to be built prior to flooding (obvious for magma, isn't it?) but can still be built at a water level of 1/7.

Floodgates have to be linked to [[lever]]s or [[pressure plate]]s to allow them to be opened and closed remotely. An open floodgate also can be walked through, whereas a closed one can not.

For example, a water floodgate connected to a river can be opened to create a shallow pool, then closed, the pool then be drained or allowed to evaporate. The resulting mud can be used for underground [[farm]]s. Standing water can be used for drinking, or sufficiently rushing water used as a defense against invaders.

If there is no roof above a floodgate, and water comes to it from a source with higher elevation, the water can spill over it.

If a magma floodgate is opened, the magma will flow over it and melt any non-magma-safe mechanism, thus breaking the open/close trigger. Using magma-safe mechanisms will prevent this from happening.

The floodgate can also be used to cover fortifications when they are not being used. This will prevent enemies from firing into your fort through the fortifications, and can be useful if your marksdwarfs arrive at the fortification one at a time.

Unlike doors, floodgates can be built directly adjacent to each other; that is, floodgates do not require an adjacent wall. This allows channels wider than two squares to be regulated. This characteristic also permits for the construction of "siege doors", allowing areas wider than two tiles to be sealed off from the enemy. For instance, the three tile wide access point for a Trade Depot within the fortress can be closed down into a chokepoint with floodgates and a lever, giving your marksdwarves more of a chance to shoot invaders.

Once activated, it will take approximately 100 steps for the floodgate to open or close: the same as bridges.

== Floating Dwarves and etc ==

Certain situations can occur that will break pathfinding on a dwarf and leave him stranded in the air. Building a stairs to his location doesn't seem to help.

== Floating Boulders ==
If you dig an up ramp to a tile with boulders, then remove the up ramp, the boulders may end up floating in midair.

== Rewalling Quirks ==

# Diagonal rewalling is silently pathblocked.
# Rewalling from the top of a ramp is apparently silently pathblocked.

== Optimal pathfinding ==

When digging an area from two ends (ie. farm from outside river and inside hallway) dwarves sometimes choose to start digging from the other end, causing them to run back and forth, digging just one rock at a time in worst case.

== The Most Dangerous Game ==

If you have two or more miners digging a channel, they ''will'' try to dig it under each other's feet, sending their fellows plummeting into the hole.

Related but not really: If you ask a dwarf to remove a floor you've built, he will -stand on it- while removing it. Problematic if, say, it's over a hundred-yard cliff.

== Contents Under Pressure ==

Melting metal items produces a crapload of metal.

== Making Metal Bars ==

At [[Talk:Galena]] a bug is mentioned that apparently gives you less metal bars than you should have when producing them at a smelter. I havent confirmed it though. --[[User:Mizipzor|Mizipzor]] 17:35, 31 October 2007 (EDT)

This refers to alloys. When making an alloy, only one bar is created, instead of the 2-4 that are supposed to show up. Avoid alloys until the version after 0.27.169.32a is released.--[[User:McFrugal|McFrugal]] 20:08, 31 October 2007 (EDT)

== Ducky Go Down The Hoooole ==

Wells crash the game now and then.

== Infinite Blood ==

For some reason, blood is constantly 'growing'. Blood from an accident in the centre of the village (wooden buildings) seems to be spreading further and further without dissapearing. --[[User:Plasma|Plasma]] 20:23, 31 October 2007 (EDT)

== Hole in a Wall ==

If a dwarf removes a floor that's on top of a wall, the dwarf will get stuck, and the Visualisation reveals that the floor tile of that wall is completely missing. --[[User:Plasma|Plasma]] 20:23, 31 October 2007 (EDT)

== We All Fall Down==

If a dwarf goes to remove a floor, he removes it while standing on it, and will subsequently fall down if there's no ground underneath. --[[User:Plasma|Plasma]] 20:23, 31 October 2007 (EDT)

40d:Dwarf fortress mode

2007-10-30T14:26:52Z

Plasma:

After creating a new world, most new users will play in fortress mode. In fortress mode, you pick a location in your world, then assign your seven initial dwarves some starting skills and pick items and animals to bring along. When the game starts, unlike previous versions, you will not be presented with the typical |river|field|cliff| layout that we are all used to, but instead with whatever area of the map you picked. There is a new Z axis (up and down) which you probably have to use if you picked a non mountainous area. You can get to the different layers using {{K|>}} (down) and {{K|<}} (up). To dig to other layers first designate a down staircase, then go down a layer and designate and up staircase below it. You can then build buildings and workshops in the space you have dug out.

As there is no promise of finding a Cave River, farming must now require the lower level of the nearest river to be tunneled out to connect to your fortress. Although the water will flow through the new passage on its own, it will move very slowly, and the miners will be able to escape with ease. Also note that floodgates will no longer speed the water flow up, and will only keep the water out.

It is suggested that digging downwards to get further in the game is to replace digging to the right in the older versions, and that better stones and ore can be found lower down.
