Do screw pumps pressurize magma, allowing the magma to go up to the hight of the screw pump?

Do magma vents fill from the top or bottom?

Yes, pressurized magma is a well know secret. Due to this property some players have constructed magma cannons.

By Armok thats dwarven!

[speculation]The tiles seem to use the pit(maximum magma level) and the current magma level(where to spawn the magma if not over maximum magma level) to determine where to spawn the magma at.  If it's missing one of those it seems to not know what to do and sits idle.[/speculation]

All other experiments I have done failed to activate the tiles.

So there's no way to hack in a "maximum magma level"? Presumably it's there for pits already because pits use the same generation process as magma pipes

Does catching fish in a river have anything to do with the actual number of vermin swimming in the water?

Does smoothing walls only improve the value of the room from the side they're smoothed from?

Yes!

Bottom

No dependence at all

Haven't seen or run a conclusive test myself.

Edit: This thread is heavily full of fail, i'm just throwing pebbles at a flash flood. To passers-by, I recommend you test all these things yourself or ask someone knowledgable, I only got to page 6 in this thread and already saw more ignorant statements and falsely-busted "myths" than I could count on both hands :>

You're not being very nice. This is one of my favorite threads!

This isn't necessarily a myth, but it is a question I'm interested in. What determines the exact value of a room? There's some info on the wiki here but it looks like some of it is out of date.

Anyway, I came up with a theoretical list that all you bored mythbusters can attempt to verify.

I think the value of a room is broken down like this:

• The sum of the values of all furniture.
• The sum of all floor and wall tiles as follows:
• For unsmoothed, natural floors and walls, the material value of the floor or wall is added.
• For smoothed, natural floors and walls, the material value is multiplied by five, and then added.
• For engraved, natural floors and walls, the material value is multiplied by five from smoothing, and then multiplied by the quality modifier of the engraving, and then added.
• For constructed walls and floors, the material value of the building material is multiplied by five and added.

For furniture adding to the value, as far as I can tell, the answer is "usually".  Every room I've ever made, the furniture's value has added directly to the room...except when the room is 1x1 over a bed, in which case its value is only half that of the bed (rather than the bed's full value).  For instance, if I base a 1x1 room on a -bed-, the value will be 10, rather than 20.

I eventually got fed up with trying to come up with an equation, and gave up on it.  Hopefully somebody will have the patience to get it all figured out.  Also, I haven't tried with multiple overlapping rooms though and haven't tried with non-bedrooms (i.e. tombs, offices, etc.).

And yes, the wiki is thoroughly out-of-date, so much so that it's just plain WRONG.

I read this on the wiki.

Cage traps capture creatures that set them off in cages. After a creature is captured, it's stored, cage and all, in an animal stockpile. Then the trap is reloaded with another cage. You can do all sorts of fun things with captured creatures. Creatures in cages will not be fed, they will survive indefinitely without nourishment. Cage traps will alert you to ambushes when triggered by hidden invaders, making a useful forward defense mechanism.

Now, as far as I know, all non civ creatures do not require food or drink, so of course they can survive indefinately in a cage.  However, the wiki seems to imply that a dwarf/ human/ etc. can also survive indefinately in a cage without food or water.

I tried this once (unintentionally, dwarf ran away from orc siege after being mangled to bits), and my poor dwarf champion died of thirst in his cage.  Is the wiki just plain wrong, or am I doing something incorrectly?

The other is about steel vs. iron anvils.  Can anyone point me to somewhere where someone has shown this to be one way or the other?

[zchris13]

We know, for a fact, that iron vs. steel anvils, the answer is yes.  Neither is better.

Dorfs need water and food in cages. Wasn't true until a little while ago.

The bottom tile is a generator tile.  It makes magma.

What would happen if you put one of these generator tiles in the sky? I know it would require tweaking or hacking or something, but it's just too dwarfy not to do.

Well, I have some gen settings that let you dig underneath se'eral magma pipes on embark, no adv visit beforehand. They don't behave particularly oddly- though you can't dig through them, either.

dwarves can create infinite pressure and water with a powered pump.

required:power source, power setup, pump, single body of water, walled in 1X1 area to pump into, over the single body of water.

The next question: is there some way to do that with magma?

Magma-proof pump?

[Leafsnail]

Anyone done it?

[Andir]

Anyone done it?

yes, search the wiki for magma pump.

[Firnagzen]

Anyone done it?

Going to try the magma generator as soon as I have time.

I don't believe it has to be a 1x1 walled in area, though, as I discovered to my chagrin while trying to drain a river. It's just that the area allows it to work faster.
