40d Talk:Lever

floodgates vs. doors misinformation?

"Therefore, it is more logical to use doors, at least until doors aren't usable for holding back water."

I'm fairly certain that doors can't be closed while flooded. They work as described for opening via lever, but cannot close when blocked by water or creatures. Granted, the last time i've levered doors was back in 2d. Please verify or change the wording? --Vaevictus 15:49, 2 June 2008 (EDT)

In the current version^{v0.27.176.38c} doors can close if water currently occupies the same square. I believe elsewhere the wiki states this destroys the water, but I have not verified if the water is destroyed. --quartic 16:18, 2 June 2008 (EDT)

Does it matter how much water? -- Vaevictus 13:35, 3 June 2008 (EDT)

I have verified this with water of depth 1 and 7, but not values in between.--quartic 13:38, 3 June 2008 (EDT)

Todo: Check whether two levers connected to the same door operate it in the same way the older versions did - that is, pulling each lever once would open the door, then do nothing as the second lever is pulled. -- Zaratustra 19:23, 7 November 2007 (EST)

I'm using vertical bars as portcullis for my keep, and they attach to levers. Perhaps a comment that bars and grates operate identically in this version, specifically with respect to levers? -Gotthard

controlling at a distance

Does the lever need to be adjacent to the item it is controlling?

I want to put a floodgate at the end of a channel... GarrieIrons 02:52, 23 January 2008 (EST)

No, it can be anywhere.--Dorten 02:57, 23 January 2008 (EST)

so, analog to the support-cave-in-trap how about building a nice water basin, say 4x4 for a start and covering it with grates, all connected to a lever - do grates have to be attached to a wall or floor on one side? I will try *broad grin* --Koltom 21:45, 22 February 2008 (EST)

Grates must be attached to a wall on one side, although you can put grates next to only grates and the dwarves will build them. Followed by their collapse. Like walls off bridges.--Draco18s 18:31, 2 March 2008 (EST)

Try building supports under them. SL's hand of armok uses supports under hatches in a similar way. VengefulDonut 23:37, 2 March 2008 (EST)

Yeah, its not working like i wanted it too. The support thing will probably work. Or I will just leave a few walls in the basin..will try that later, busy right now. *watches goblin fly away in high arc* --Koltom 19:52, 3 March 2008 (EST)

Regarding remote activation/control: I just spent 10 minutes berating my dwarves for completely ignoring two Pull Lever commands while vile forces of darkness approached, only to find that once I removed the Dwarves Stay Indoors restriction, they happily stepped up to the, uh, lever. The bridges are outside, the levers are on the level below. Has anyone else experienced this? Holyfool 17:49, 22 March 2008 (EST)

Was the lever and/or any part of the path to the lever marked as "outside"? Use k to check. --Savok 10:25, 23 March 2008 (EDT)

I checked and one of the levers was indeed marked "outside". In fact, there are several squares on my first underground level that are marked "outside". Is that because they are in the general area of the stairway leading outside? Thank you for the info. --Holyfool 18:42, 29 March 2008 (EDT)

When I quit reading all new forum messages and stayed at the wiki, I thought this would stop. Read The Wiki. Really. Read it. No, really, click on that link. --Savok 19:57, 29 March 2008 (EDT)

Megabeasts

I have noticed that a bridge that a hydra is standing on cannot be retracted ^{v0.27.176.38c}. Has anyone else had similar experiences? VengefulDonut 00:15, 13 March 2008 (EDT)

Titans cause the same problem. I conjecture that bridged can't be retracted while megabeasts are standing on them. VengefulDonut 02:08, 13 March 2008 (EDT)

Also elephants, it seems. Possibly creature size. VengefulDonut 13:18, 13 March 2008 (EDT)

Dragons cause the same problem. Are megabeasts supposed to all show up at once like this? VengefulDonut 21:43, 13 March 2008 (EDT)

Proposed addition: Mechanism sequence

Given the problems that arise when using non magma-safe materials for mechanisms on floodgates, it is quite handy to know which mechanisms go where at the link selection (When for example you're really low on bauxite).
From my experimentation with floodgate-lever, the first mechanism selected goes at the gate and the second one at the lever. I still haven't activated the contraption, but I'm assuming it's going to be ok.
I'm also assuming the same is usefull for grates and bars. --User:Nonickch, unsigned

There is some lower-down text that tells you which mechanism goes in where. --Savok 08:30, 15 June 2008 (EDT)

Finding Links

Is it possible to determine what a lever is linked to without pulling it and checking to see what happens? -Fuzzy 00:43, 6 September 2008 (EDT)

AFAIK the only way is to attempt to link the lever to a built object and notice which one if any is not available.

eg if you have two bridges but only one is available to be linked to, it is because you are already linked to the other one.

This would be a really good feature if it was implemented.

GarrieIrons 09:55, 6 September 2008 (EDT)

I guess this is one good use for the new note-feature: Just use the same note for lever and target. --Doub 10:17, 6 September 2008 (EDT)
