That pretty neat. I wasn't aware magma would keep outdoor water from freezing. There is a lot that could be done with this.

[peterix]

prepare three tunnels.
one with magma on z-1. it's floor is made of retractable bridges.
second on z0 with a few levels of water. attach repeaters and pressure plates to atom-smash excess water. the floor is solid
third tunnel on z-2 is the one that serves as magma storage and is hooked up to the z-1 one by pumps.

Add timed mechanisation and you're done (a thing that closes the bridges and opens a floodgate blocking pump flow at the same time and vice-versa)

one lever operation.

And all of this is fairly dependent on my thinking that glass pumps do not deconstruct if magma gets on the front tile...

If anything that is not magma safe shares a tile with magma, it'll melt. I'll think about making a wider hallway feasible though.

Except that it wouldn't... http://www.bay12games.com/forum/index.php?topic=27423.msg333562#msg333562

Vindication!

[Shadowics]

SUCCESS!

It's a bit messy, but the freezer mk1 is up and running, fully automatic freeze thaw cycles!

Not quite perfect, the perpetual-motion-waterwheels driving my screwpumps stall occasionally..

First things first though.. waiting for some 'test subjects' to give it a go...

[Shadowics]

Good news everyone! (though bad news too, unfortunately)


Bad news: My first test was a catastrophic failure. The sieging goblins walked straight through my 'Ice Wall'. STRAIGHT THROUGH!!!!  It didn't even slow them down, much less freeze them.

Good news: Unwilling to let my hard work go to waste, I save-scummed to try again. After some trial and error, I discovered the problem. The bridge beneath their feet was somehow protecting them from the ice completely encasing them, and enabling them to walk through it as if it wasn't there. Removing the bridge solved that problem.

Bad news: As it turns out, flash-freezing in ice atom-smashes anything that was there. No corpse, no bones, no clothing, no weapons, nothing.

Good news: That means the trouble making bridge was completely useless, as there's nothing left behind in the trap corridor to clean out.


I'm going to report both of these issues as bugs, and we'll see where it goes from there.

This is good news for your FPS.

I was hoping for suspended animation orcs.

Dwarven physics in action once again!

(goblin+water) x magma = goblin bits in obsidian

(goblin+water) x freezing = EVERYTHING GONE!

Hmm... Maybe, when the gobbo unfreezes, his molecules are teared apart and dissolved in the frozen water? Technically it won't be "gone", but dissapeared indeed! Then, when the ice melts back in to water, the gobbo is gone!

The goblin disappears the moment the ice freezes, he doesn't even appear 'imbedded' until thawing.

It's worse than you think: Not only do the goblins still appears on the unit list as deceased. All their equipment, weapons, armor, clothing, bones, etc, still shows up on the stocks list! The ice having forever pushed it into an alternate dimension, invisible and untouchable. The items have 'water covering' and zooming to them shows me the tile in the ice path where the gobbo died. But neither unforbidding nor marking for dumping allows the dwarfs to retrieve it. It's the worse possible news, not only can they not be melted down or traded away, they can't even be burnt or chasmed.

[Lehmusjoki]

Oh. That's bad, then.

[Shoku]

Yeowch. Guess I'm never building one of these then.

[Shadowics]

Yeowch. Guess I'm never building one of these then.

Well, they both seem to be bugs. There is a listing already on the known bugs page for
000713 □ [dwarf mode][items] (Report) items can disappear when ice melts after being imbedded
which is kinda what's happening (though they never appear imbedded). Hopefully they'll get fixing at some point and then I can resurrect this project.

[Shadowics]

Update! With possibly good news!

The items, previously described as 'destroyed' or 'stuck in an alternate dimension' are in fact retrievable! Any amount of items can be perfectly preserved embedded in nothing until you choose to retrieve it.

The goblin bodies, equipment, etc were stuck in the melted ice walls. Pouring more water into the same tiles, letting it freeze, then mining it out spontaniously generated huge piles of garbage, as dozens of dead goblins poured out.

This appears to be on the known bugs list as bug 000713 □ [dwarf mode][items] (Report) items can disappear when ice melts after being imbedded. Bug: When ice melts, as opposed to being dug out, embedded items remain embedded in nothing.

[Jim Groovester]

Ah, that's excellent news. And not just about being able to retrieve items.

It's good to know I can send caged prisoners to the Phantom Zone.
