cage traps for food

Couldn't one generate a mild supplementary food source by putting cage traps out on the map at random? Or create rows of them to catch aggressive creatures that are chasing down a fleeing dwarf. The ability to place them on the surface has some interesting possibilities. Kefkakrazy 04:45, 4 November 2007 (EST)

You can really do this with any kind of trap now - I built a 1 tile wide stair/corridor up an exposed cliff face, and as I was concerned about goblins and the like I stonefall-trapped it. Ever since then some of the local wildlife has used it to get up and down the 5 z-level cliff, with predictable and hilarious results. The goats just die, but the marmots are hurled off the cliff face to splatter on the ground below. It's a nice easy meat/leather/fat source, as well as being entertaining "Dwarfy McDwarf cancels reload stone trap - interrupted by (flying) hoary marmot" Acama 19:48, 20 December 2007 (EST)

berserk dwarves

Will berserk dwarves set off pressure plates? Toady mentioned he was going to stop that from happening VengefulDonut 19:39, 4 November 2007 (EST)

flooding a spiked pit

Will flooding a spiked pit break or cancel the spike trap? I'd test this, but I don't have the channel dug in yet. --Xazak 18:30, 5 November 2007 (EST)

confirmed that flooding doesn't affect spear/spike traps. YayTheDwarves 17:52, 6 January 2008 (EST)

I'm pretty sure the "corpse stuck in trap" chance is 50%, according to Toady either on IRC or some forgotten forum post a few months back. I really can't remember for sure. -EarthquakeDamage 02:31, 10 November 2007 (EST)

cage traps/ fire imps

I've secured the entries oy my magma furnaces with cage traps, but it seems that the fire imps just walk through. Just as the Giant moles did. How so? --Doub

supposedly there is a bug that causes any creatures on the map when it is generated to count as residents, and thus know where your traps are and not trigger them. I've never run into the problem myself, but I've never specifically tested for it so I can't really say for sure if it still exists (or ever did). --BurnedToast 07:41, 6 January 2008 (EST)

I had read about this and tried it out with a trapped coridoor next to my magma vent - an imp I tempted out walked right through 4 cage traps and 4 stonefall traps without triggering them. Seems like indigenous life is currently trap-immune. Most magma creatures can be dealt with by a few marksdwarves though, so you're only in serious trouble if you have a herd of skeletal hippos on your map on embark.--TangoThree 15:42, 19 January 2008 (EST)

There's always the menacing spike + lever combo. And pits. Benitosimies 16:08, 10 March 2008 (EDT)

I'm planning on making the only passage to my fortress filled with cage traps, but I'm not sure if dwarves going out and migrants and traders coming in will be affected by them. Does anyone know? Also, do trolls smash goblin cages? Patarak 21:41, 23 January 2008 (EST)

Only hostile units will trigger traps. Trolls only smash buildings and after a goblin is captured the cage is not built. So the answer to your second question is no. --Karlito 21:45, 23 January 2008 (EST)

Make sure to forbid the traps when the siege starts. Otherwise your dwarves will rush out to reload them and store all the cages. --Ikkonoishi 22:53, 23 January 2008 (EST)

Is it possible that Kobold thieves/Goblin master thieves can also trigger traps? I think I killed one and caged another master thief in the past. Maybe the quality of the mechanism is important here? --Qwertyu 13:24, 17 March 2008 (UTC+1)

goblin thieves, both regular and master, have always triggered traps -Chariot 14:18, 17 March 2008 (EDT)

So why does the article then say "Sneaking enemies do not trigger traps"? Goblin master thieves seem very sneaky to me. --Qwertyu 20:33 17 March 2008 (UTC+1)

once goblin thieves are revealed they are captured fine. even revealed kobolds dont trigger. -Chariot 15:45, 17 March 2008 (EDT)

At least "normal" goblin thieves are scewered fine without being detected, says my weapon trap --Koltom 16:58, 17 March 2008 (EDT)

I have to agree with Koltom, I got an "Ambush" event when a goblin (master) thief went into a cage trap, and had another one cut to pieces by a serrated disc, which I only noticed when suddenly all my dwarves rushed off to remove his clothes. --Qwertyu 13:31 (UTC+1)

Crossbow Trap?

How does a crossbow trap work? Does it have line of sight, like a Dwarf?
